CAUTION

1. 24-V Power Supplies Required for UL Certification

PCON controllers (PCON-C/CG, CY, SE, PL/PO) are UL-certified, where one condition for the certification is to use Class 2 24-V power supplies.

Accordingly, you must use Class 2 power supplies for both the input power supply and I/O power supply for your equipment incorporating the PCON, if the equipment as a whole must be UL-certified.

PCON controllers can be used in an environment of pollution degree 2 or equivalent.

3. PC Software and Teaching Pendant Models

New functions have been added to the entire PCON controller series.

To support these new features, the communication protocol has been changed to the general

Modbus (Modbus-compliant) mode. As a result, the existing PC software programs and teaching pendants compatible with RCP2 controllers can no longer be used.

If you are using this controller, use a compatible PC software program and/or teaching pendant selected from the following models.

4. Recommendation for Backing up Latest Data

This product uses nonvolatile memory to store the position table and parameters. Normally the memory will retain the stored data even after the power is disconnected. However, the data may be lost if the nonvolatile memory becomes faulty.

(We strongly recommend that the latest position table and parameter data be backed up so that the data can be restored quickly in the event of power failure, or when the controller must be replaced for a given reason.)

The data can be backed up using the following methods:

[1] Save to a CD or FD from the PC software.

[2] Hand write the position table and parameter table on paper.

CAUTION

5. Initial Parameter Settings at Startup

After applying power, at least the three parameters specified below must be set in accordance with the specific application.

Inappropriate settings of these parameters will prevent the controller from operating properly, so exercise due caution.

For details on how to set the parameters, refer to “Parameter Settings” in the operation manual for the PC or teaching pendant.

[1] Selecting the PIO pattern

This controller provides six PIO pattern types to meet the needs of various applications.

To select a desired type, set a corresponding value from 0 to 5 in parameter No. 25 (PIO pattern selection).

The factory setting is “0 [Standard type].”

Parameter No.

25 setting

Feature of PIO pattern type

A basic type supporting 64 positioning points and two zone outputs.

* How to set zone boundaries within which to output a zone signal:

Zone boundaries are set using parameter Nos. 1 and 2 for one zone output, and in the position table for another zone output.

2

3

In this type, 64 positioning points and one zone output (boundaries are set in the position table) are supported.

In addition to the normal positioning mode, the user can also select the teaching mode in which the actuator can be jogged via commands from a PLC and the current actuator position can be written to a specified position.

(Note 1) Jog commands from a PLC are also accepted in the positioning mode.

(Note 2) Positions can be rewritten by approximately 100,000 times.

256-point positioning type

The number of positioning points is increased to 256, so only one zone output is available (boundaries are set in the position table).


The number of positioning points is increased to 512, so no zone output is available. type

The number of positioning points is limited to seven to offer separate direct command inputs and position complete outputs for respective positions.

PLC ladder sequence circuits can be designed easily. type

Use of the controller as an air cylinder is assumed in this type.

Position complete output signals function differently in this type, compared to the 7point type.

Specifically, the signal functions not only to “indicate position complete,” but also to

“detect a position” in the same manner as auto-switches of an air cylinder.

CAUTION

[2] Enabling/disabling the servo ON input signal (SON)

The servo ON input signal has been added to allow for servo ON/OFF control on the PLC side.

Depending on the needs, therefore, the user must enable/disable this signal.

To select a desired setting, set “0” or “1” in parameter No. 21 (Servo ON input disable selection).

Setting

Enable (use)

Disable (do not use)

The factory setting is “0 [Enable].”

[3] Enabling/disabling the pause signal (*STP)

The pause signal uses the contact b logic to provide a failsafe function.

Therefore, this signal must remain ON in normal conditions of use.

Since there are applications where this signal is not used, a parameter is provided to disable the pause signal so it doesn’t have to be turned ON.

To select a desired setting, set “0” or “1” in parameter No. 15 (Pause input disable selection).

Setting

1. Overview

1.1 Introduction

This product is a dedicated RCP2 actuator controller that provides the same functions of the RCP2 controller as well as a set of new functions designed to achieve greater convenience and safety.

The product also provides a power-saving function in response to growing energy-saving needs.

The key features and functions are listed below. z More positioning points

The standard type supports up to 64 points, while the extended types can handle up to 512 points.

Availability of more positioning points is ideal for production lines where many types of products are produced in small volumes. z Setting of zone output boundaries for each position in the position table

Before, zone output boundaries were set by parameters and therefore fixed. To add flexibility, new fields have been added to the position table so that different boundaries can be set for each position.

This feature is useful in preventing contact with surrounding equipment and reducing the tact time, among others. z Separate acceleration/deceleration settings

Acceleration and deceleration are now set in separate fields of the position table.

Depending on the material or shape of the load, it is desirable to reduce shock and vibration when the actuator stops.

Since acceleration and deceleration can be set differently, only the deceleration value can be reduced to make the deceleration curve more gradual. z Limitation of feed speed in test operation and adjustment

The feed speed to be used in test operation and adjustment can be limited for added safety. z Power-saving measures

In general, pulse motors consume more holding current in standstill state than AC servo motors. This product provides a power-saving means to support situations where the actuator must stand by for a long period.

When actually starting up your system or if you have encountered any problem, also refer to the operation manuals for the actuator, teaching pendant, PC software and other components used with the system, in addition to this manual.

This manual does not cover all possible operations other than normal operations, or unexpected events such as complex signal changes resulting from use of critical timings.

Accordingly, you should consider items not specifically explained in this manual as “prohibited.”

* We have made every effort to ensure accuracy of the information provided in this manual. Should you find an error, however, or if you have any comment, please contact IAI.

Keep this manual in a convenient place so it can be referenced readily when necessary.

[2] Install the controller. applicable actuator.

→ Chapter 3, “Installation”

Wiring/connection

• Wire the 24-V power supply.

• Connect the grounding wire to ground.

• Wire the emergency stop circuit and motor drive power supply.

• Connect the motor cable and encoder cable.

• Connect the I/O flat cable.

4

Turn on the power and check for alarms

Supply the 24-V power after confirming that the emergency stop circuit is not actuated.

If the monitor LED [SV/ALM] on the front face of the controller illuminates for two seconds and then turns off, the controller is functioning properly. If [SV/ALM] illuminates in red, it means an alarm has generated.

Connect a PC or teaching pendant to check the nature of the alarm, and remove the cause by referring to

Chapter 10, “Troubleshooting.”

5

Set the PIO pattern/safety speed

Set the mode selector switch on the front face of the controller to the “MANU” side.

On the PC screen or teaching pendant, set the MANU operating mode to [Teaching mode: Enable safety speed/Inhibit PIOs].

In this condition, set appropriate values in parameter No. 25 (PIO pattern selection) and parameter No. 35

(Safety speed).

* The factory-set PIO pattern and safety speed are “standard type” and “100 mm/s or less,” respectively.

→ Chapter 8, “Parameter Settings”

6

Turn on the servo

Confirm that the slider or rod is not contacting a mechanical end.

If the slider/rod is contacting a mechanical end, move it away from the mechanical end.

If the actuator is equipped with a brake, turn on the brake forced-release switch to forcibly release the brake before moving the actuator.

The load may suddenly drop when the brake is released, so exercise due caution not to pinch your hand or damage the robot hand by the falling load.

Turn on the servo from the PC or teaching pendant.

If the actuator enters a servo lock mode and the monitor LED [SV/ALM] on the front face of the controller illuminates in green, the controller is functioning properly.

7

Check the operation of the safety circuit

Confirm that the emergency stop circuit (or motor drive-power cutoff circuit) operates properly.

→ Chapter 4, “Wiring”

8

Set a target position

Perform home return first, and then set a target position in the “Position” field for each position in the position table. Determine a desired position by finely adjusting the load or robot hand.

* Once a target position is set, all other fields (speed, acceleration/deceleration, positioning band, etc.) will be automatically populated with their default values.

→ Chapter 6, “Position Table Settings”

* To ensure safety, it is recommended that the safety speed be enabled during initial movements.

To move the actuator at the actual speed set in the “Speed” field of the position table, change the

MANU operating mode to [Teaching mode 2: Disable safety speed/Inhibit PIOs].

9

Trial operation and adjustment

Set the mode selector switch on the front panel of the controller to the “AUTO” side.

Input a movement command from the PLC to perform positioning.

If necessary, perform fine adjustments including the items specified below:

• Vibration or noise may generate depending on the weight, material or shape of the load. If vibration or noise is observed, lower the speed, acceleration and/or deceleration.

• To prevent contact with surrounding equipment or reduce the tact time, adjust the boundaries for each zone output signal and also adjust the positioning band.

• Adjust the current-limiting value, judgment time and push speed to be used in push & hold operation.

Caution: Before changing any parameter, set the mode selector switch to the “MANU” side. Or, keep the mode selector switch on the “AUTO” side and turn on the MODE input signal.

Explanation of each switch

If multiple axes are used, the PC/teaching pendant must be plugged into/out of different connectors to communicate with different axes.

To save the hassle, you can use link cables to connect all axes via SIO converters.

Under this method, however, the PC/teaching pendant must be able to identify each axis by the number assigned to the axis.

This switch is used to set this number.

For details, refer to Chapter 9, “How to Connect a PC/Teaching Pendant to Multiple Axes.”

[2] Mode selector switch

This interlock switch is used to prevent unexpected movement or data rewrite as a result of duplicate operation in which a movement command is input from the PLC and operation using the PC/teaching pendant is performed at the same time.

AUTO: Always set to the “AUTO” side during auto operation using PIO signals from the PLC.

MANU: Always set to the “MANU” side during operation using the PC/teaching pendant.

[3] Brake release switch

When the actuator is equipped with a brake, this switch is used to forcibly release the brake.

3. Installation and Noise Elimination

Pay due attention to the installation environment of the controller.

Environment

(1) When installing and wiring the controller, do not block the cooling ventilation holes. (Insufficient ventilation will not only prevent the controller from demonstrating its full performance, but it may also cause breakdown.)

(2) Prevent foreign matter from entering the controller through the ventilation holes. Since the enclosure of the controller is not dustproof or waterproof (oilproof), avoid using the controller in a place subject to significant dust, oil mist or splashes of cutting fluid.

(3) Do not expose the controller to direct sunlight or radiating heat from a large heat source such as a heat treatment furnace.

(4) Use the controller in an environment free from corrosive or inflammable gases, under a temperature of 0 to 40

°C and humidity of 85% or less (non-condensing).

(5) Use the controller in an environment where it will not receive any external vibration or shock.

(6) Prevent electrical noise from entering the controller or its cables.

The power supply specification is 24 VDC

± 10%.

(Supply current: 2 A max.)

This section explains how to eliminate noise in the use of the controller.

(1) Wiring and power supply

[1] Provide a dedicated class D grounding using a wire with a size of 2.0 to 5.5 mm

2

or larger.

Controller

Use a cable of a maximum possible size and keep the wiring length at a minimum.

Metal frame

Class D grounding

Other equipment

Good

Controller

Other equipment

Avoid this grounding method.

12

[2] Precautions regarding wiring method

Use a twisted cable for connection to the 24-VDC external power supply.

Separate the controller cables from high-power lines such as a cable connecting to a power circuit. (Do not bundle together the controller cables with high-power lines or place them in the same cable duct.)

When extending the supplied motor cable or encoder cable, consult IAI’s Technical Support.

(2) Noise sources and elimination

Among the numerous noise sources, solenoid valves, magnet switches and relays are of particular concern when building a system. Noise from these sources can be eliminated by implementing the measures specified below.

[1] AC solenoid valves, magnet switches and relays

Measure: Install a surge absorber in parallel with the coil.

Å Point

Install a surge absorber to each coil over a minimum wiring length.

Installing a surge absorber to the terminal block or other part will be less effective because of a longer distance from the coil.

[2] DC solenoid valves, magnet switches and relays

Measure: Install a diode in parallel with the coil. Determine the diode capacity in accordance with the load capacity.

In a DC circuit, connecting a diode in reverse polarity will damage the diode, internal parts of the controller and/or DC power supply, so exercise due caution.

13

3.4 Heat Radiation and Installation

Design the control panel size, controller layout and cooling method in such a way that the temperature around the controller will not exceed 40

°C.

Install the controller vertically on a wall, as shown below. Since cooling is provided by way of natural convection, always observe this installation direction and provide a minimum clearance of 50 mm above and below the controller to ensure sufficient natural airflows.

When installing multiple controllers side by side, providing a ventilation fan or fans above the controllers will help maintain a uniform temperature around the controllers.

Keep the front panel of the controller away from the wall (enclosure) by at least 95 mm.

Fan

50 mm or more

95 mm or more

50 mm or more

Airflow

Regardless of whether your system consists of a single controller or multiple controllers, provide sufficient clearances around each controller so that it can be installed/removed easily.

5. I/O Signal Control and Signal Functions

The standard interface specification of the controller is NPN, but the PNP specification is also available as an option.

To prevent confusion during wiring, the NPN and PNP specifications use the same power line configuration. Accordingly, there is no need to reverse the power signal assignments for a PNP controller.

5.2 PIO Patterns and Signal Assignments

This controller provides six PIO pattern types to meet the needs of various applications.

To select a desired type, set a corresponding value from 0 to 5 in parameter No. 25 (PIO pattern selection).

The features of each PIO pattern are explained below:

Parameter No.

25 setting

Feature of PIO pattern

0

Positioning mode (Standard type)




1

2

3

Teaching mode (Teaching type)


In addition to the normal positioning mode, the user can also select the teaching mode in which the actuator can be jogged via I/Os and the current actuator position can be written to a specified position.

(Note) Positions can be rewritten by approximately 100,000 times.

256-point mode (256-point positioning type)


512-point mod (512-point positioning)

The number of positioning points is increased to 512, so no zone output is available.

4

Solenoid valve mode 1 (7-point type)

The number of positioning points is limited to seven to offer separate direct command inputs and movement complete outputs.

PLC ladder sequence circuits can be designed easily.

5 Solenoid valve mode 2 (3-point type)


Movement complete output signals function differently in this type, compared to the 7point type.

Specifically, the signal functions not only to “indicate movement complete,” but also to

“detect a position” in the same manner as auto-switches of an air cylinder. Push & hold operation cannot be performed.

(Note) For “Zone” and “Position zone,” different methods are used to set boundaries defining the range within which the zone signal will turn ON.

“Zone” is set by parameter Nos. 1 and 2, and thus its setting will become effective after home return is completed.

“Position zone” is set in the “Zone+” and “Zone-“ fields for each position number in the position table, and thus its setting will become effective after a movement command is input.

5.2.1 Explanation

The following explains the signal names, and gives a function overview of each signal.

In the explanation of operation timings provided in a later section, each signal is referenced by its selfexplanatory name for clarity. If necessary, however, such as when marker tubes are inserted as a termination of the flat cable, use the signal abbreviations. z PIO pattern = 0: Positioning mode [Standard type]

Caution: [1] The signals indicated by * in the table (*ALM, *STP and *EMGS) are based on the negative logic, meaning that they remain ON in normal conditions of use.

[2] Do not connect pins denoted by “Not used” (orange-1, yellow-1, blue-4, purple-4, gray-

4), but insulate them instead.

[3] The NPN and PNP specifications use the same power line configuration, so there is no need to reverse the power signal assignments for a PNP controller.

[4] The LOAD/TRQS signal is available only with the PCON-CF controller.

5.3 Details of I/O Signal Functions

An input time constant is provided for the input signals of this controller, in order to prevent malfunction due to chattering, noise, etc.

Except for certain signals, switching of each input signal will be effected when the signal has been received continuously for at least 6 msec. For example, when an input is switched from OFF to ON, the controller will only recognize that the input signal is ON after 6 msec. The same applies to switching of input signals from ON to OFF (Fig. 1).

5.3.1. Details of Each Input Signal

Operating mode (RMOD)

This controller has a mode selector switch on the front panel of the controller to prevent malfunction and data loss due to duplicate operations.

Normally this switch should be set to the “AUTO” position when the actuator is operated in the auto mode using I/O signals exchanged with a PLC, or to the “MANU” position when the actuator is operated manually using a PC or teaching pendant.

If the controller is mounted in a control panel, however, this switch is not readily accessible. Accordingly, a function has been added to allow the setting of this switch to be changed from a PLC for added convenience.

Specifically, the internal operating mode of the controller will become “AUTO” when this signal is turned

OFF, or “MANU” when this signal is turned ON, if the mode selector switch is set to the “AUTO” position.

If the mode selector switch is set to the “MANU” position, the internal operating mode of the controller will remain “MANU” regardless of the status of this signal.

Use this signal in applications where the operation mode must be switched frequently between auto and manual and the selector switch is provided on the equipment side.

Start (CSTR)

Upon detecting an OFF Æ ON rise edge of this signal, the controller will read, as a binary code, the target position number consisting of six bits from PC1 to PC32 (or eight bits from PC1 to PC128 when the PIO pattern is “256-point type,” or nine bits from PC1 to PC256 when the PIO pattern is “512-point type”), and execute positioning to the target position of the corresponding position data.

Before executing this command, the target position, speed and other operation data must be set in the position table using a PC/teaching pendant.

If a start command is issued when home return operation has not been performed yet after the power was input (the HEND output signal is OFF), the controller will automatically perform home return operation before positioning to the target position.

Command position number (PC1 to PC256)

When a movement command is effected upon OFF

→ ON of the start signal, the nine-bit binary code consisting of signals PC1 to PC256 will be read as the command position number.

In the standard or teaching type, six bits of PC1 through PC32 are used. In the 256-point type, eight bits of

PC1 to PC128 are used. In the 512-point type, nine bits of PC1 through PC256 are used.

The weight of each bit is as follows: 2

0

for PC1, 2

1

for PC2, 2

2

for PC4, …, and 2 position number between 0 and 511 (maximum) can be specified.

Pause (*STP)

When this signal turns OFF while the actuator is moving, the actuator will decelerate to a stop.

The remaining movement is retained and will be resumed when the signal is turned ON again.

To abort the movement command, turn ON the alarm reset signal while this signal is OFF to cancel the remaining movement.

The *STP signal can be used for the following purposes:

[1] Provide a low-level safety measure to stop the axis while the servo is ON, such as a sensor that detects a person approaching the system

[2] Prevent contact with other equipment

[3] Perform positioning based on sensor or LS detection

(Note) If the *STP signal is input while the actuator is performing home return, the movement command will be retained if the actuator is yet to contact a mechanical end. If the signal is input after the actuator has reversed upon contacting a mechanical end, home return will be performed again from the beginning.

Home return (HOME)

The controller will start home return operation upon detection of an OFF

→ ON edge of this signal.

When the home return is complete, the HEND signal will be output. The HOME signal can be input as many times as required.

Servo ON (SON)


When the power is turned on, make sure this signal will turn ON after the safety of the entire equipment is ensured, i.e., after a confirmation that the actuator will not contact surrounding equipment.

If the SON signal need not be used in view of the nature of the equipment, you can disable the signal using parameter No. 21.

When this signal is disabled, the servo will turn on automatically after the power is turned on.

The factory setting is to enable the SON signal.

Alarm reset (RES)

This signal provides two functions.

[1] Reset the alarm output signal (*ALM) that turned OFF due to an alarm

If an alarm has generated, turn ON this signal after confirming the nature of the alarm.

The controller will reset the alarm upon detection of a rise edge of the RES signal.

(Note) Certain alarms cannot be reset by the RES signal. For details, refer to 10, “Troubleshooting.”

[2] Cancel the remaining movement when the pause signal is OFF

This function is used when the remaining movement must be cancelled to allow for incremental moves (movements at a constant increment) from the position where the actuator stopped following a sensor detection.

49

Brake release (BKRL)

When the actuator is equipped with a brake, you may want to forcibly release the brake in certain situations such as when starting up the system for the first time. Normally the brake release switch on the front panel of the controller is set to the “RLS” side to release the brake. For added convenience, the brake can now be released from the PLC.

If this signal is ON while the servo is off, the brake is released.

Use this signal to provide a release switch near the actuator when the actuator is located away from the controller.

Operation mode (MODE)

This signal is effective when the teaching type is selected.

When this signal is turned ON while the actuator is standing still, the normal operation mode will change to the teaching mode.

The controller will turn ON the MODES output signal upon receiving this signal.

Program the PLC so that it will accept a current-position write command after confirming that the MODES output signal is ON.

When this signal is turned OFF, the controller will return to the normal operation mode.

Current-position write (PWRT)

This signal is enabled when the aforementioned MODES output signal is ON.

When this signal has remained ON for 20 msec or longer, the controller will read the position number specified by a binary code consisting of PC1 through PC32 as currently detected, and write the current position data in the “Position” field of the corresponding position number.

If data of other items (speed, acceleration/deceleration, positioning band, etc.) are yet to be defined, the default settings of the corresponding parameters will be written.

When the writing completes successfully, the WEND output signal will turn ON.

Configure the system in such a way that the PLC will turn OFF the PWRT signal when WEND turns ON.

The controller will turn OFF WEND once the PWRT signal turns OFF.

(Note) An alarm will generate if a write command is issued when home return has not been performed yet or while the actuator is moving.

Manual operation switching (JISL)

This signal is enabled when the teaching type is selected.

The JISL signal is used to switch operations in the manual mode. Specifically, the actuator will jog when this signal is OFF, or inch when this signal is ON.

If this signal is turned ON while the actuator is jogging, the actuator will decelerate to a stop.

If this signal is turned OFF while the actuator is inching, the actuator will continue with its inching movement.

50

Jog (JOG+, JOG-)


When the actuator is jogging (i.e., the JISL signal is OFF), it will jog toward the +/- software stroke limit upon detection of an OFF Æ ON rise edge of this signal.

If an ON Æ OFF fall edge of this signal is detected while the actuator is moving, the actuator will decelerate to a stop.

The jogging speed is defined by parameter No. 26, “PIO jog speed.”

* If any of the following input signal changes occurs while the actuator is jogging, the actuator will decelerate to a stop:

[1] Both the JOG+ and JOG- signals have turned ON.

[2] The JISL signal has turned ON (i.e., the operation mode has changed to inching).

[3] The CSTR signal has turned ON (i.e., a positioning command has been input).

Upon detection of an OFF Æ ON rise edge of this signal while the actuator is inching (i.e., the JISL signal is ON), the actuator will travel the distance defined in parameter No. 48, “PIO inching distance.”

The actuator will continue with its inching movement if this signal is switched while the actuator is inching.

Caution: If jogging or inching is performed before a home return is completed, the actuator may collide with a mechanical end because the software stroke limits are not yet effective.

Exercise due caution.

Direct position command (ST0 to ST6) [7-point type]

These signals are effective when “4” is set in parameter No. 25.

Upon detection of an OFF Æ ON rise edge of this signal or detection of the ON level of the signal, the actuator will move to the target position set in the corresponding position data.

Before executing this command, the target position, speed and other operation data must be set in the position table using a PC/teaching pendant.

If ON edges of two or more signals are detected at the same time, priority will be given to the position command of the smallest number among all detected command signals. (Example: If ON edges of ST0 and ST1 signals are detected at the same time, the actuator will start moving to position 0.)

Although commands are executed upon detection of an ON signal edge, priority is given to the command that was specified the earliest. In other words, a signal input will not be accepted while the actuator is moving. Even if a different position signal is turned ON while the actuator is moving, the actuator will not commence moving to the new position after reaching the target position.

Movement to each position (ST0 to ST2) [3-point type]

Since the number of positioning points is limited to three, the actuator can be controlled just like an air cylinder.

While this signal is ON, the actuator will move toward the target position.

If the signal turns OFF while the actuator is moving, the actuator will decelerate to a stop.

Before executing this command, enter a target position in the “Position” field for position No. 0, 1 or 2 in the position table.

5.3.2 Details of Each Output Signal

Operating mode status (RMDS)

The internal operating mode of the controller is output based on the AUTO/MANU selector switch on the controller and the RMOD signal received by the input port. If the selector switch is set to “AUTO” and the

RMOD signal is OFF (AUTO), the controller is in the AUTO (OFF) mode. If the selector switch is set to

“MANU” and/or the RMOD signal is ON (MANU), the controller is in the MANU (ON) mode.

Completed position number (PM1 to PM256)

These signals can be used to check the completed position number when the PEND signal turns ON.

The signals are output as a binary code.

Immediately after the power is input, all of the PM1 to PM256 signals are OFF.

In the standard or teaching type, six bits of PM1 through PM32 are used. In the 256-point type, eight bits of PM1 through PM128 are used. In the 512-point type, nine bits of PM1 through PM256 are used.

All of these signals are OFF also when the actuator is moving.

As described above, this signal is output only when positioning is completed.

(Note) All of these signals will turn OFF when the servo is turned OFF or an emergency stop is actuated.

They will return to the ON status when the servo is turned ON again, provided that the current position is inside the in-position range with respect to the target position. If the current position is outside the range, the signals will remain OFF.

When the power is input, the PEND signal will turn ON. These signals are all OFF, this condition is the same as one achieved after positioning to position “0” is completed.

Check the position of position 0 after the movement command has completed.

If an alarm is present, the corresponding alarm code (abbreviated form) consisting of four bits from PM1 to

PM8 will be output.

The meanings of these signals vary between the normal condition and the alarm condition, so be careful not to use them wrongly in the sequence.

Moving (MOVE)

This signal is output while the servo is ON and the actuator is moving (also during home return, push & hold operation or jogging).

Use the MOVE signal together with the PEND signal to allow the PLC to determine the actuator status.

The MOVE signal will turn OFF after positioning or home return is completed or a judgment is made during push & hold operation that the load is being contacted.

Position complete (PEND)

This signal indicates that the target position was reached and positioning has completed.

Use the PEND signal together with the MOVE signal to allow the PLC to determine the positioning status.

When the controller becomes ready after the power was input and the servo has turned ON, this signal will turn ON if the position deviation is within the in-position range.

Then, when a movement command is issued by turning ON the start signal, the PEND signal will turn

OFF. It will turn ON again when the deviation from the target position falls within the in-position range.

Once turned ON, the PEND signal will not turn OFF even when the position deviation subsequently exceeds the in-position range.

(Note) If the start signal remains ON, the PEND signal will not turn OFF even when the deviation from the target position falls within the in-position range: it will turn ON when the start signal turns OFF.

Even when the motor is stopped, the PEND signal will remain OFF if the pause signal is input or the servo is OFF.

53

Home return completion (HEND)

This signal is OFF immediately after the power is input, and turns ON in either of the following two conditions:

[1] Home return operation has completed with respect to the first movement command issued with the start signal.

[2] Home return operation has completed following an input of the home return signal.

Once turned ON, the HEND signal will not turn OFF unless the input power supply is cut off, a soft reset is executed, or the home return signal is input again.

The HEND signal can be used for the following purposes:

[1] Check prior to establishing the home if movement toward the home direction is permitted, in cases where an obstacle is located in the direction of the home

[2] Use as a condition for writing the current position in the teaching mode

[3] Use as a condition for enabling the zone output signal

Zone (ZONE1, ZONE2)

[1] ZONE1

This signal will remain ON while the current actuator position is inside the zone specified by Parameter

No. 1, “Zone boundary+” and Parameter No. 2, “Zone boundary-,” or OFF while the actuator is outside this range. This signal is always effective once home return has been completed and is not affected by the servo status or presence of an alarm.

(Note) This signal becomes effective only after the coordinate system has been established following a completion of home return. It will not be output immediately after the power is turned on.

[2] PZONE

This signal will turn ON when the current actuator position enters the area between the zone boundaries set in the position table. After the current position movement command is completed, the signal will remain effective until the next position movement command is received.

Current operation mode (MODES)


The MODES signal will turn ON when the teaching mode is enabled upon selection of the teaching mode via the operation mode input signal (MODE signal ON).

Thereafter, the MODES signal will remain ON until the MODE signal turns OFF.

Configure the system in such a way that the PLC will start teaching operation after confirming that the

MODES signal has turned ON.

Write completion (WEND)

This signal is enabled only when the teaching type is selected.

The WEND signal is OFF immediately after the controller has switched to the teaching mode. It will turn

ON when the writing of position data in response to the current-position write signal is completed.

When the current-position write signal turns OFF, this signal will also turn OFF.

Configure the system in such a way that the PLC will acknowledge completion of writing when the WEND signal turns OFF.

54

Movement complete at each position (PE0 to PE6) [7-point type]

When PIO pattern is “4,” a position number (0 through 6) corresponding to each movement command will be output upon completion of positioning. Simple alarm-code output function is not provided for these signals. If an alarm generates, only the *ALM signal will turn OFF. Check the details of the alarm code using each tool.

Note) These signals turn OFF when the servo is turned OFF or an emergency stop is actuated. They will return to the ON status when the servo is turned ON again, provided that the current position is inside the in-position range with respect to the target position. If the current position is outside the range, the signals will remain OFF.

Position detection output at each position (LS0 to LS2) [3-point type]

These signals have the same meanings as the LS signals of an air cylinder. Each signal will turn ON when the current position enters the positioning band of the target position.

(Note) Even if the servo turns off or an emergency stop is actuated while the actuator is stopped at the target position, the signal will remain ON as long as the actuator is inside the positioning band.

Output signal Position detected Remarks

Ready (SV)

This is a monitor signal indicating that the servo is ON and the motor is ready.

Use this signal as a condition for starting a movement command on the PLC side.

Alarm (*ALM)

This signal remains ON while the controller is operating properly, and turns OFF when an alarm has generated.

Provide an appropriate safety measure for the entire system by allowing the PLC to monitor the OFF status of this signal.

For details of alarms, refer to 10, “Troubleshooting.”

55

Emergency stop (*EMGS)

This signal remains ON while the controller is normal, and will turn OFF if the emergency stop circuit is cut off.

Program the PLC so that it will monitor this signal and implement appropriate safety measures for the entire system if the signal turns OFF.

Load output judgment status (LOAD) * This is a dedicated signal available only with the PCON-CF.

If used in a press-fitting application, the controller must be able to know if the specified load threshold was reached during push & hold operation.

A desired load threshold and check band range are set in the position table, and this signal will turn ON when the command torque exceeds the threshold while the actuator is inside the check band range.

With the LOAD signal, judgment is made based on whether the total duration of periods in which the command torque has exceeded the threshold corresponds at least to a specified time. The specific processing procedure is the same as the one used when determining a completion of push action. The time used for judgment of load output can be changed freely using user parameter No. 50, “Load output judgment time.”

Torque level status (TRQS) * This is a dedicated signal available only with the PCON-CF.

If a load threshold is set, this signal will turn ON when the motor current reaches the load threshold while the actuator is moving.

Since the level of current is monitored, the ON/OFF status of this signal will change when the current changes.

In the weak field-magnet vector control used for stepping motors, the balance of current and torque will be lost once a specific speed is exceeded. To use the command current to determine if the threshold has been reached, therefore, the push speed must be limited. Note, however, that the range of permissible push speeds varies depending on the motor and lead, which means that the push speed set in user parameter No. 34 must also be adjusted according to the applicable motor and lead.

6. Data Entry <Basics>

To move the actuator to a specified position, a target position must be entered in the “Position” field.

A target position can be specified in the absolute mode where a distance from the home is entered, or in the incremental mode where a relative travel from the current position is entered.

Once a target position is entered, all other fields will be automatically populated with their default values set by the applicable parameters.

The default values vary depending on the characteristics of the actuator.

Basically, the acceleration and deceleration should be inside the rated acceleration/deceleration range specified in the catalog.

The input range is greater than the rated range in the catalog to accommodate situations where you want to “reduce the tact time when the load mass is significantly smaller than the rated load capacity.”

If vibration of the load causes problem during acceleration/deceleration, decrease the set value.

Increasing the set value makes the acceleration/deceleration quicker while decreasing the value makes it more gradual.

Caution: Refer to the attached list of supported actuator specifications and set appropriate speed and acceleration/deceleration so that the actuator will not receive excessive impact or vibration under the applicable installation condition and for the load of the specific shape.

Increasing the speed and acceleration/deceleration may significantly impact the actuator depending on the load mass, and the actuator characteristics also vary from one model to another. Contact IAI for the maximum limits that can be entered in your specific application.

* This field is available only with the PCON-CF controller.

• The meaning of this field varies between “positioning operation” and “push & hold operation.”

“Positioning operation”

This field defines how much before the target position the completion signal will turn ON.

Increasing the positioning band allows the next operation in the sequence to be started early, and consequently the tact time can be reduced. Set an optimal value by checking the overall balance of the system.

Holding current can be reduced by servo-controlling the pulse motor.

Although the exact level of current reduction varies depending on the actuator model, load condition, etc., the holding current will decrease by approx. 1/2 to 1/4.

Since the servo remains on, position deviation will not occur.

The actual holding current can be checked in the current monitor screen of the PC software.

Automatic servo-off mode

After positioning is completed, the servo will turn off automatically upon elapse of a specified time.

(Since no holding current generates, power consumption will decrease.)

When the next movement command is received from the PLC, the servo will turn on and the actuator will start moving.

Upon reaching the target position set in the “Position” field of the position table, the actuator moves at the push speed for the distance set in the “Positioning band” field.

If the actuator contacts the load while moving and the controller recognizes that “push action has completed,” the position complete signal will turn ON.

(maximum push distance)

The push speed is set by parameter No. 34.

The factory setting varies with each actuator in accordance with the actuator’s characteristics.

Set an appropriate speed by considering the material and shape of the load, among others.

Since the maximum speed is 20 mm/s, operate the actuator at a speed not exceeding this value.

Set a positioning band slightly longer than the last position, in order to absorb possible mechanical variation of the load.

“Completion of push action” is determined based on a combination of the current-limiting value set in the “Push” field of the position table and the push completion judgment time set by parameter No. 6.

Set an appropriate condition by considering the material and shape of the load, among others.

For details, refer to Chapter 8, “Parameter Settings.”

Warning

• If the actuator contacts the load before reaching the target position, a servo error alarm will generate. Pay due attention to the relationship of the target position and the load position.

• The actuator continues to push the load at the push force at standstill determined by the current-limiting value. Since the actuator is not inactive, exercise due caution when handling the machine in this condition.

(2) Load was not contacted (missed)

If the actuator does not still contact the load after having moved the distance specified in the “Positioning band” field, the position complete signal will not turn ON.

Therefore, include timeout check processing in the sequence circuit on the PLC side.

• It is recommended that a zone signal be also used as a “simple ruler” to supplement the judgment of missed load.

(3) Load moves during push & hold operation

[1] Load moves in the pushed direction

If the load moves in the pushed direction after completion of push action, the actuator will chase the load within the positioning band.

If the current drops to below the current-limiting value set in the “Push” field of the position table while the actuator is moving, the position complete signal will turn OFF. The position complete signal will turn ON when the current-limiting value increases to the specified level again.

The push speed is set by parameter No. 34, “Push speed.”

The factory setting varies with each actuator in accordance with the characteristics of the actuator.


Take note, however, that the maximum speed is limited to 10 mm/s.

Set parameter No. 51, “Torque check range” to “0 [Enable].”

6.2.4 Speed

Speed control involving multiple speed levels is possible in a single operation. The actuator speed can be decreased or increased at a certain point during movement.

However, the position at which to implement each speed change must be set.

Position 1 Position 2 Position 1 Position 2 Position 1 Position 2 Position 3

6.2.5 Operation at Different Acceleration and Deceleration Settings

If the load is a CCD camera or other precision equipment, the deceleration curb at stop must be made as gradual as possible.

To accommodate these sensitive applications, the position table has separate fields for “acceleration” and

“deceleration.”

For example, you can set the deceleration differently from the acceleration, such as setting 0.3 G (rated acceleration) in “Acceleration” and 0.1 G in “Deceleration.”

Speed

Acceleration:

0.3 G

Starting position

Deceleration:

Time

Caution: Basically, the acceleration and deceleration should be inside the rated acceleration/deceleration range specified in the catalog.

The input range is greater than the rated range in the catalog, but this is only to accommodate situations where you want to “reduce the tact time when the load mass is significantly smaller than the rated load capacity.”

If you want to use acceleration/deceleration settings greater than the rating, consult IAI beforehand because it may affect the life of the actuator.

70

6.2.6 Pause

The actuator can be paused during movement using an external input signal (*STP).

The pause signal uses the contact b logic (always ON) to ensure safety.

Turning the *STP signal OFF causes the actuator to decelerate to a stop. When *STP is turned ON subsequently, the actuator will resume the remaining movement.

(Note) The deceleration corresponds to the value set in the “Deceleration” field for the current position number in the position table.

6.2.7 Zone Signal Output

The zone output is suitable for the following applications, because a signal can be output when the actuator enters a specified zone during movement:

[1] Issue a trigger signal to surrounding equipment to reduce the tact time

[2] Prevent contact with surrounding equipment

[3] Use as a “simple ruler” in push & hold operation

A different method is used for the zone output signal, and for the position zone output signal, to set the zone within which the signal will turn ON.

Return

After the power is turned on, home return must be performed to establish the home position.

The method of home return varies depending on the PIO pattern. z When a dedicated input is used [PIO pattern

≠ 5]

Home return is performed using the home return (HOME) input.

The actuator will return home regardless of whether or not home return has been completed once before.

When home return is completed, the home return complete (HEND) output signal will turn ON. z When a dedicated input is not used [PIO pattern = 5]

When a rear end move command is input while home return is not yet completed, the actuator will perform home return first and then move to the rear end.

For details, refer to 7.2, “How to Execute Home Return.”

72

of

Depending on your system, it may be desirable to be able to use a touch panel, etc., to perform jogging operation or write the current position to the “Position” field of the position table, without using a PC or teaching pendant.

The teaching type is provided to support these applications.

The features of the teaching type are summarized below:

[1] The actuator can be jogged using I/O signals input from the PLC.

Continuous jog feed or inching feed can be selected by the manual switching signal to facilitate fine position adjustment.

* This function is effective regardless of the ON/OFF state of the operation mode input (MODE) signal.

[2] The current position can be written to the “Position” field of the position table using I/O signals input from the PLC.

* This function is effective only when the operation mode input (MODE) signal is ON.

(Note) The number of I/O points is limited, so some I/O ports are used in both the teaching type and the normal positioning type. Remember this when creating a sequence circuit for the PLC.

Warning: Jog commands are effective even before home return is completed, but the soft stroke checks are not performed prior to home return. Accordingly, the actuator may move all the way to the mechanical end if the jog command (JOG+/JOG-) signal remains ON.

Exercise caution not to let the actuator hit the mechanical end.

73

6.2.10 Overview of 7-point Type

The number of positioning points is kept small, or specifically to seven or less. This type assumes simple applications where the PLC ladder sequence only requires a simple circuit configuration.

I/O signals provide separate command inputs and movement complete outputs for respective position numbers.

Accordingly, the signal pattern is different from the one in the 64-point positioning type (PIO pattern = 0).

Example) The differences are explained by using an example of moving the actuator to the target position for position No. 5. type

The key differences between this controller and an air cylinder are summarized in the table below.

Program appropriate controls by referring to this table.

Determined in accordance with the load, supplied air volume, as well as the performance of the speed controller and electromagnetic valve.

Desired coordinates are entered in the [Position] field of the position table.

Accordingly, external detection sensor is not required.

A desired feed speed is entered in the [Speed] field of the position table (unit: mm/sec).

Note that the rated speed is automatically set as the initial value.

Desired acceleration/deceleration are entered in the

[Acceleration] and [Deceleration] fields of the position table

(minimum setting unit: 0.01 G).

Reference: 1 G = Gravitational acceleration

Note that the rated acceleration/deceleration is automatically set as the initial value.

Since the acceleration/deceleration can be set in fine steps, a gradual acceleration/deceleration curve can be programmed.

RCP2

Immediately after the power is turned on, the controller cannot identify the current position because the mechanical coordinates have been lost.

Accordingly, a rear end command must always be executed after the power is turned on, to establish the coordinates.

The actuator will perform home-return operation first, and then move to the rear end.

Power is turned on here.

Home position

Rear and position

[1] The actuator moves at the home return speed toward the mechanical end on the motor side.

[2] The actuator contacts the mechanical end and turns back, and then stops temporarily at the home position.

[3] The actuator moves to the rear end at the speed set in the

[Speed] field of the position table.

(Note) Pay attention not to allow any obstacle in the travel path of the actuator during home return.

The relationship of each movement command input/position detected and corresponding position number is shown below.

The input/output signals are given easy-to-identify names by following the naming convention of air-cylinder switches.

However, the target position is determined by the value set in the [Position] field for each position number.

Therefore, changing the magnitude relationships of settings under position Nos. 0, 1 and 2 will change the meanings of input/output signals.

For this reason, it is recommended that you always use the signals under their names defined in this manual, unless doing so presents problem, so that the signals have the same meanings at all time.

6.3 Notes on the ROBO Gripper

(1) Finger

[1] Definition of position

The specified stroke of the 2-finger type indicates the sum of travel distances of both fingers. In other words, the travel distance of one finger is one half the specified stroke.

A position you specify defines the distance traveled by one finger from the home position in the closing direction.

Accordingly, the maximum command value is 5 mm for the GRS type and 7 mm for the GRM type.

[2] Definition of speed and acceleration

The command value applies to each finger.

The relative speed and acceleration of the 2-finger type are twice the command values.

[3] Operation mode in gripper applications

When the actuator is used to grip the load, be sure to select the “push & hold mode.”

(Note) In the “positioning mode,” a servo error may occur while the load is gripped.

78

(2) Removing the gripped load

This gripper is designed to maintain the load-gripping force via a self-lock mechanism even when the servo is turned OFF or the controller power is cut off.

If the gripped load must be removed while the power is cut off, do so by turning the open/close screw or removing the finger attachment on one side.

[2-finger type]

Turn the open/close screw or remove the finger attachment on one side.

6.4 Power-saving Modes at Standby Positions

One general feature of pulse motors is that their holding current in standstill state is greater than AC servo motors.

Therefore, this product provides energy-saving modes to reduce power consumption in situations where the actuator remains standstill for a long period at a standby position.

Use these modes after confirming that they will not present problems to any part of your system.

Each mode produces a different level of power-saving effect. Follow the instructions provided below and select an optimal mode appropriate for the specific standstill condition of your actuator. z PIO pattern = 5: Solenoid valve mode 2 [3-point type]

The actuator stands by with the servo on after the power has been turned on

In this condition, you can select full servo control using parameter No. 53 (Default standstill mode).

Automatic servo-off control cannot be selected. If you have set 1, 2 or 3 by mistake, the setting will be ignored.

(This setting is not affected by the value in the “Standstill mode” field of the position table.)

The actuator stands by after completing the positioning to the target position set in the “Position” field for the applicable position number

In this condition, you can select one of two modes based on the value in the “Standstill mode” field of the position table.

(This setting is not affected by the value of parameter No. 53.)

[1] Full servo control

[2] Automatic

● PIO pattern = Other than 5: Solenoid valve mode 2 [3-point type]

The actuator stands by after completing the home return operation effected by the HOME input signal

In this condition, you can select one of two modes based on the value of parameter No. 53 (Default standstill mode).

(This setting is not affected by the value in the “Standstill mode” field of the position table.)

[1] Full servo control servo-off control

The actuator stands by after completing the positioning to the target position set in the “Position” field for the applicable position number

In this condition, you can select one of two modes based on the value in the “Standstill mode” field of the position table.

(This setting is not affected by the value of parameter No. 53.)


2. Meanings of values set in the “Standstill mode” field of the position table and in parameter No. 53

The pulse motor is servo-controlled to reduce the holding current.

Although the exact degree of current reduction varies depending on the actuator model, load condition, etc., the holding current decreases to approx. 1/2 to 1/4.



Take note that micro-vibration or noise may occur in certain conditions where external force is applied, or depending on the position where the actuator has stopped.

If micro-vibration or noise presents problem, do not use this mode.



(Since no holding current flows, power consumption will decrease.)


* Since the servo turns off once, some position deviation may occur. Do not use this function at standby positions where position deviation will cause problem.

You should also note that the position complete (PEND), completed position number (PM1 to PM256) and movement complete (PE0 to PE6) signals will turn OFF because the servo turns off. However, you can keep the signals ON via a parameter in situations where the PLC sequence circuit is designed in such a way that problems will occur if complete signals turn OFF.

Setting of parameter No. 39

PE6) signal status

0 [PEND] The signal will turn OFF unconditionally when the servo turns off.

Even when the next movement command is issued and the servo turns on again, the actuator has already started moving to the next target position, so the signal still remains OFF.

1 [INP]

(Note) The factory setting is “0.”

Even when the servo is off, the signal turns ON if the current position is within the range set by the “Positioning band” field of the position table, with respect to the target position, and turns OFF if the current position is outside this range.

Warning: If the next movement command is specified in the incremental mode (based on constant pitch feed), never use the automatic servo-off mode. The current position may deviate slightly as the servo turns off and then on again.

Caution: In push & hold operation, both the full servo control mode and automatic servo-off mode become ineffective once the operation has completed successfully.

If the actuator has missed the load, the specified mode becomes effective.

Basically, you should not use either the full servo control mode or automatic servo-off mode in push & hold operation.

7. Operation <Practical Steps>

7.1 How to Start

7.1.1 Timings after Power On

Procedure after initial startup until actuator adjustment

[1] Connect the motor relay cable to the MOT connector and encoder relay connector to the PG connector.

[2] Connect the supplied flat cable to the PIO connector (for connection between the host PLC and I/O unit).

[3] Reset the emergency stop or enable the supply of motor drive power.

[4] Supply the 24-VDC I/O power (1A/2A pins (+24 V) and 19B/20B pins (0 V) in the PIO connector).

[5] Supply the 24-VDC controller power (24-V and 0-V terminals on the power-supply terminal block).

* If the monitor LED [SV/ALM] on the front panel illuminates for 2 seconds initially and then turns off, the controller is normal. If [SV/ALM] illuminates in red, an alarm is present. In this case, connect a PC or teaching pendant to check the nature of the alarm and remove the cause by referring to Chapter 10, “Troubleshooting.”

[6] Set the minimum set of required parameters initially.

Set the mode selector switch on the front panel to the “MANU” side.

On the PC or teaching pendant, set the MANU operation mode to “Teaching mode: Enable safety speed].

Change the necessary parameters in this condition.

(Example)

• Use a PIO pattern other than “Standard type” → Parameter No. 25 (PIO pattern selection)

• Reduce the safety jog speed → Parameter No. 35 (Safety speed)

[7] Check the actuator position.


If the slider/rod is contacting a mechanical end, move it away from the mechanical end. If the slider/rod is not contacting a mechanical end but is closer to the home position, move the slider/rod away from the home position.


The slider/rod may suddenly drop due to its dead weight when the brake is released, so exercise caution not to damage the robot hand or load by the falling slider/rod.

If the actuator cannot be moved by hand because the screw lead is short, change the setting of parameter No. 28 (Default direction of excited-phase signal detection) to the direction opposite to the mechanical end.

Warning

If the servo is turned ON while the slider/rod is contacting the mechanical end, excitation phase detection may not be performed correctly and an abnormal operation or excitation detection error may result.

[8] Turn on the servo.

Turn on the servo using the “servo ON function” of the PC software or teaching pendant.

If the actuator enters a servo lock mode and the monitor LED [SV/ALM] on the front panel illuminates in green, the controller is functioning properly.

[9] Check the operation of the safety circuit.

Confirm that the emergency stop circuit (or motor drive-power cutoff circuit) operates properly.

83

[10] Perform home return. z Overview of operation on the teaching pendant

• On the RCM-T, select the “Edit/Teach” screen, bring the cursor to “*Home” in the sub display area, and then press the Return key.

• On the RCM-E, select the “Teach/Play” screen, scroll until “*Home Return” is displayed, and then press the Return key.

[11] Set a target position in the “Position” field of the position table.

Set a target position in the “Position” field of each position table.

Determine a desired target position by fine-adjusting the load and hand via jogging or inching.

Also adjust the servo gain, if necessary.

* Once a target position has been set, other fields (speed, acceleration/deceleration, positioning band, etc.) will be automatically populated by their default values. Set optimal values for the speed, acceleration/deceleration, positioning band, etc.

* For safety reasons, it is recommended that the safety speed be enabled during the initial movement.

To move the actuator at the actual speed set in the “Speed” field of the position table, change the

MANU operation mode to [Teaching mode: Disable safety speed].

(If the home return signal is input while SV is OFF, the signal input will be ignored.)

6 msec or less

Continuous operation starts.

86

Warning: Since the drive motor uses a pulse motor, excited-phase detection is performed when the servo is first turned on after the power on.

Therefore, the actuator must be able to move when the servo turns on.

If the slider or rod is contacting a mechanical end or the load is contacting any surrounding equipment, excited-phase detection will not be performed correctly and an abnormal operation or excited-phase detection error may occur.

In this case, move the actuator by hand to a position where it can move before the servo turns on.

If the actuator is equipped with a brake, the brake must be forcibly released by turning on the brake release switch. The slider/rod may suddenly drop due to its dead weight when the brake is released, so exercise caution not to pinch your hand or damage the robot hand or load by the falling slider/rod.

If the actuator cannot be moved by hand, one possible solution is to change the setting of parameter No. 28 (Default direction of excited-phase signal detection). If you wish to change this parameter, consult IAI beforehand.

87

7.1.2 Position Table and Parameter Settings Required for Operation

Startup adjustment

Immediately after the system has been started, the moving speed can be reduced by the methods specified below to ensure safety of operators and prevent damage to jigs, etc.

Change the applicable parameters, if necessary.

→ For details on the setting-change operations, refer to the operation manual for your PC software/teaching pendant.

Safety speed during manual feed

To move the actuator using the PC/teaching pendant, set the mode selector switch on the front panel of the controller to the “MANU” side.

For safety reasons, it is recommended that the actuator be moved at the safety speed during manual feed.

To do this, change the MANU operation mode to [Teaching mode: Enable safety speed] on the

PC/teaching pendant.

The safety speed is defined by parameter No. 35. Change the parameter value, if necessary.

Take note that the maximum speed is limited to 250 mm/s or below.

The factory setting is “100 mm/s” or below.

Speed override for movement commands from the PLC

You can lower the feed speed to be applied when the actuator is moved by the movement commands output from the PLC.

To lower the speed to below the level set in the “Speed” field of the position table, you can use parameter

No. 46 to override the “Speed” field.

Actual moving speed = [Speed set in the position table] x [Value of parameter No. 46]

÷ 100

Example) Value in the “Speed” field of the position table 500 (mm/s)

Value of parameter No. 46 20 (%)

Under the above settings, the actual moving speed becomes 100 mm/s.

The minimum setting unit is “1%,” while the input range is “1 to 100 %.” The factory setting is “100 %.”

88

Full-scale operation

This product provides energy-saving modes to reduce power consumption in situations where the actuator remains standstill for a long period at a standby position.

You can also select the status of position complete signal to be applied if the servo turns off or “position deviation” occurs while the actuator is standing still after completing positioning.

Use these functions after confirming that they will not present problems to any part of your system.

Saving energy when the actuator stands by for a long time after the power has been turned on

Applicable to PIO pattern = 5 (3-point type)

In this condition, you can select full servo control using parameter No. 53 (Default standstill mode). (This setting is not affected by the value in the “Standstill mode” field of the position table.)

Saving energy when the actuator stands by after completing the home return operation effected by the

HOME input signal

Applicable to PIO pattern = 0 to 4

In this condition, you can select one of two modes based on the value in parameter No. 53 (Default standstill mode). (This setting is not affected by the value in the “Standstill mode” field of the position table.)

[1] Full servo control

[2] Automatic

Saving energy when the actuator stands by for a long time at the target position

Common to all PIO patterns

In this condition, you can select one of two modes based on the value in the “Standstill mode” field of the position table. (This setting is not affected by the value in Parameter No. 53.)


→ For details, refer to 6.4, “Power-saving Modes at Standby Positions” and 8.2.2, “Parameters Relating to the Actuator Operating Characteristics.”

Output mode of complete signal

Applicable to PIO pattern = 0 to 4

You can select the status of position complete signal to be applied if the servo turns off or “position deviation” occurs while the actuator is standing still after completing positioning.

This setting uses parameter No. 39. Consider the characteristics of the control you need and select an appropriate mode.

→ For details, refer to 8.2.3, “Parameters Relating to the External Interface.”

7.2 Home Return Operation

7.2.1 Method Using the HOME Input Signal (PIO Pattern = 0 to 4)

Since the home return signal (HOME) is provided in PIO patterns 0 to 4, perform home return using this signal.

• When the home return signal (HOME) turns ON, the actuator starts moving toward the mechanical end on the home side.

Once the mechanical end is contacted, the actuator reverses its direction and moves, and then stops at the home position.

• At the start of movement, the position complete output (PEND) turns OFF while the moving output

(MOVE) turns ON.

• When the actuator stops at the home position, the position complete output (PEND) and home return complete output (HEND) turn ON. On the other hand, the moving output (MOVE) turns OFF.

• On the PLC side, turn OFF the home return signal (HOME) after the home return complete output

(HEND) has turned ON.

Caution: When performing home return, pay attention to the following:

[1] Confirm that no obstacle is present in the home return direction.

[2] If any obstacle is present in the home return direction, review the PLC sequence circuit and change the circuit so that home return will be executed only when there is no obstacle.

90

(Note) If the home is not yet established immediately after the power has been turned on, directly inputting the command position signal and start signal without inputting the home return signal

(HOME) first will cause the actuator to perform home return operation and then move to the target position.

However, it is recommended that the PLC sequence circuit use the home return signal (HOME) to prevent errors.

7.2.2 Method Used When No HOME Input Signal Is Available (PIO Pattern = 5)

Since no home return signal (HOME) is available in PIO pattern 5, input the rear end move command

(ST0) first to perform home return.

• When the rear end movement command (ST0) turns ON, the actuator starts moving toward the mechanical end on the home side.

Once the mechanical end is contacted, the actuator reverses its direction and moves to the home position, stops temporarily at the home position, and then moves to the rear end.

• Once the home position is reached, the home return complete output (HEND) turns ON.

Caution: When performing home return, pay attention to the following:

[1] Confirm that no obstacle is present in the rear end direction.

[2] If any obstacle is present in the rear end direction, move the actuator toward the front end and remove the obstacle. Issuance of the front end move command is permitted for this reason. In this case, the actuator moves forward at the home return speed and when the actuator reaches the mechanical end, the front end position complete output (LS1) turns ON.

[3] Do not input the intermediate point move command (even if the command is input, it will be ignored).

92

7.3 Positioning Mode (Back and Forth Movement between Two Points)

Example of use in operation) The actuator moves back and forth between two positions. The position 250 mm from the home is set as position 1, and the position 100 mm from the home is set as position 2. The travel speed to position 1 is set as 200 mm/sec, and to position 2 is set as 100 mm/sec.

Each command position must be input after the position complete output has turned ON for the movement to the previous position.

Caution:

• When the start signal turns ON, the position complete output will turn OFF and the moving output will turn ON.

Always turn OFF the start signal after confirming that the start signal is currently ON and the position complete output has turned OFF.

If the start input remains ON as shown below, the position complete output will not turn ON even when the actuator movement is completed.

Movement is complete.

• If another movement command to the same position is issued, the position complete output will turn OFF, but the moving output will not turn ON.

• If the position complete signal turns ON, the moving output will also turn OFF simultaneously even when the actuator is moving.

This means that, if the positioning band in the position data is increased, there may be cases where the actuator will continue to move after the moving output turns OFF simultaneously when the position complete output turns ON.

• When a software stroke limit is reached after continuous incremental moves, the actuator will stop immediately and a position complete signal will be output.

94

7.4 Push & Hold Mode

Example of use in operation) The actuator is caused to move back and forth in the push & hold mode and positioning mode. The position 280 mm from the home is set as position 1, and the position 40 mm from the home is set as position 2.

Movement to position 1 is performed in the push & hold mode (the actuator is caused to contact the load and push it in the counter-motor direction). The maximum push amount at position 1 is set as 15 mm, and the current-limiting value during the push & hold operation by the stepper motor is set as 50%.

Movement to position 2 is performed in the positioning mode. The travel speed to position 1 is set as 200 mm/sec, and that to position 2 is set as 100 mm/sec.

Each command position must be input after the position complete output has turned ON for the movement to the previous position. z Conditions for determining completion of push & hold operation

Push & hold operation is deemed to have completed upon elapse of the time set by parameter No. 6

(Push completion judgment time) after the motor current reached the current-limiting value set in the

“Push” field of the position table.

Set an appropriate value by considering the material and shape of the load, and so on.

The minimum setting unit is “1 msec,” while the maximum value is “9999 msec.” The factory setting is “255 msec.”

(Note) The chart below explains how completion of push & hold operation is determined if the load shifted during the judgment and the current has changed as a result, based on a judgment time of

255 msec.

Push current

Starting position Target position Counting starts.

The count increases to 200.

20 msec

The count decreases to 180.


75 msec

Push & hold operation is deemed to have completed.

If the motor current remains at or above the push current for 200 msec and then drops below this level for

20 msec, the count will decrease by 20. When the push current is reached again thereafter, counting will start from 180. If the motor current remains at or above the push current for 75 msec, the count will increase to 255 and thus push & hold operation will be deemed to have completed.

In total, 295 msec was required for the judgment.

96

7.4.1 Return Action after Push & Hold by Relative Coordinate Specification

z Positioning mode

The reference position is the target position for the position number used in the applicable push & hold operation.

In the aforementioned example, the actuator moves to the 240-mm position if position No. 2 is set to -40 mm in the incremental mode (280 – 40 = 240 mm).

Speed

Position where the push & hold operation completed

Return action

Returned position

240 mm

Target position

280 mm z Push & hold mode

The reference position is the position where the push & hold operation completed.

In the aforementioned example, the actuator moves to the 250.34-mm position if position No. 2 is set to

-40 mm in the incremental mode and the push & hold operation completed at 290. 34 mm (290.34 – 40 =

250.34 mm).

(Note) In this case, the controller determines that the actuator has missed the load and thus does not turn ON the position complete signal.

It is therefore recommended that the zone output signal be used to determine completion of push

& hold operation on the PLC side.

Change

Example of use in operation) The actuator speed is reduced at a certain point during movement.

The position 150 mm from the home is set as position 1, and the position 200 mm from the home is set as position 2. The actuator is initially located between the home and position 1. The actuator is moved to position 2 being the target position, at a travel speed of 200 mm/sec to position 1 and that of 100 mm/sec from position 1 to position 2.

Method) In this example, the actuator is caused to move to position 1 and to position 2 successively. Before the actuator is stopped at position 1, command position 2 must be selected/entered and the start signal must be input. To do this, set a wide positioning band at position 1 and cause the start signal for movement to position 2 to be input immediately after the completion signal for movement to position 1 is output. (Command position 2 should be entered while the actuator is moving to position 1.)

108

Method

Although completion judgment is based on the applicable count managed by the PLC, the zone output signal can be used additionally to double-check the completion of movement.

Program the PLC so that the ON/OFF status of the zone output signal is checked when positioning is completed, and if the signal is OFF, the applicable position will be determined as the last load position.

If the count in the PLC does not match the zone output signal status, signal timings may not be synchronized.

7.9.2 Notes on Incremental Mode

If an operation command is issued based on relative coordinate specification while the actuator is moving (in the normal positioning mode or push & hold mode), how the actuator will operate varies depending on whether or not push action is specified in the operation command by relative coordinate specification, as explained below.

(1) When the relative coordinate operation command specifies an operation in the normal positioning mode (without push action)

[1] When a relative coordinate operation command is specified while the actuator is moving in the normal positioning mode

If any incremental position number is selected and input and then a start signal is input while positioning is in progress, the actuator will move to the position corresponding to the target position of the initial command plus the incremental distance.

(If the incremental distance is a negative value, the actuator will move to the position corresponding to the target position minus the incremental distance.)

Example) If the start signal for movement to position 2 is input while the actuator is moving to position 1, the actuator will move to the position 215 mm from the home.

If the start signal for movement to an incremental position number is input multiple times during positioning, the actuator will move to the position corresponding to the initial position plus the “increment x number of times the signal was input.”

Example) If the start signal for movement to position 2 is input twice while the actuator is moving to position 1, the actuator will move to the position 230 mm from the home.

The following explains how the actuator will move if an incremental position number is selected and input and then a start signal is input while the actuator is moving in the push & hold mode.

Example) If the start signal for movement to position 2 is input while the actuator is moving to position 1, the actuator will move to the position corresponding to the target position set in the position 1 data plus the incremental distance. Accordingly, the push & hold mode will be cancelled.

If the position table is set as follows, the actuator will move to the 215-mm position.

7.10 Jogging/Teaching Using PIO

If the teaching type is selected, you can jog the actuator via operation from the PLC.

You can also write the current actuator position to the “Position” field of the position table under a specified position number via operation from the PLC.

If the actuator position is written to a blank “Position” field where no position has yet been defined, the positioning band and other fields will be automatically populated by their default values set in the applicable parameters.

Example of use in operation) Move the actuator to the target position by inputting a jog command from the PLC and write the achieved position to position No. 1.

When the operation mode (MODE) input is turned ON, the current operation mode (MODES) output will turn ON and the teaching mode permitting PIO teaching will become effective.

The teaching mode will not become effective unless the operation mode (MODE) input is turned ON while the actuator is stopped.

To confirm that the teaching mode is effective, check if the current operation mode (MODES) output is

ON.

If both the Jog+ input and Jog- input turn ON at the same time, the actuator will stop. In this case, turn both inputs OFF and then restart jogging.

The manual operation switching (JISL) input is ON during inching and OFF during jogging.

The inching distance is set by parameter No. 48, while the jog speed is set by parameter No. 26.

If the current-position write (PWRT) input has remained ON for 20 msec or longer, the current actuator position will be written to the selected command position number.

When writing is completed, the write complete (WEND) output will turn ON.

When the current-position write (PWRT) input is subsequently turned OFF, the write complete (WEND) output will turn OFF.

If a signal to be written is input from the PLC while the position table screen is open on the PC or teaching pendant, the position data display will not be refreshed. Perform one of the following operations to check the retrieved position data:

PC --- Click the button.

Teaching pendant --- Open the user adjustment screen and enter “4” as the adjustment number to reset the software.

7.11 Operation in 7-point Type

Separate movement command inputs are provided for the target positions for position Nos. 0 to 6, so simply turn ON the input signal corresponding to the position you wish to move the actuator to, and the actuator will start moving.

Example of use in operation) Move the actuator to position No. 0 (5 mm), position No. 1 (200 mm) and position No. 2 (390 mm) in sequence.

Caution: Movement commands are executed based on the rise edge, so input each signal continuously for 6 msec or more.

If two or more movement commands are input simultaneously, they will be executed according to the following priorities:

The priorities follow the command numbers in ascending order: [1] Direct position command

0, [2] Direct position command 1, …, [7] Direct position command 6.

The sequence circuit on the PLC side must ensure only one command is input at a time.

z The movement command input operates in two modes.

You can select the operation condition of the movement command input (ST0 to ST6) in parameter No.

27.

The factory setting is “0: [Level mode].”

Description of the movement command input Setting

Level mode:

The actuator starts moving when the input signal turns ON. When the signal turns

OFF during the movement, the actuator will decelerate to a stop and complete its operation.

0

Edge mode:

The actuator starts moving when the rise edge of the input signal is detected. The actuator will not stop even when the signal turns OFF during the movement, until the target position is reached.

z Handling of the pause (*STP) signal

This signal is a contact B signal, meaning that it must remain ON while the actuator is moving.

If the pause signal turns OFF while the actuator is moving, the actuator will decelerate to a stop.

The actuator will start moving when the signal turns ON again.

Use this signal as an interlock that actuates when an operator entry prohibition sensor or contact prevention sensor is activated.

If the pause signal is not to be used, set parameter No. 15 (Pause input disable selection) to “1,” and the actuator will move even when this signal is OFF.

(Note) When the “edge mode” is selected as the movement command type, you can change the target position while the actuator is stopped with this signal turned OFF, as follows:

[1] Input a reset signal (RES) for 6 msec or more to cancel the remaining travel.

Next, turn ON the pause signal, and then input a movement command specifying the new target position.

(Example) Turn OFF the pause signal while the actuator is moving under direct position command

1. The actuator decelerates to a stop.

→ Turn OFF direct position command 1, and turn ON the reset signal for 6 msec or more.

→ Turn ON the pause signal again, and input direct position command 2.

7.12 Operation in 3-point Type

After the power has been turned on, input the rear end move command first to complete home return, and then perform continuous operation.

→ Refer to 7.2.2, “Method Used When No HOME Input Signal Is Available.”

Example of use in operation) How to move the actuator from the rear end to the front end is explained.

Although the actuator does not stop at the intermediate point, you can increase the positioning band and use the intermediate point detected output signal (LS2) as a quasi zone output signal.

Caution: Provide a ladder sequence circuit where only one move command signal turns ON at a time. If two or more signals are input at the same time, the signals will be processed in the following priorities:

Priorities: [1] Rear end, [2] Front end, [3] Intermediate point

119

z Meaning of position detected output signals (LS0, LS1, LS2)

These signals are handled in the same manner as limit switches (LSs), and turn ON when the following conditions are met:

[1] The home return complete output signal (HEND) is ON.

[2] The current position is within the positioning band from each target position in the positive or negative direction.

Accordingly, these signals turn ON not only when the actuator is moving under a move command, but also when the actuator is moved by hand with the servo turned off.

In a case where none of these signals (LS0, LS1, LS2) is ON when an emergency stop was actuated while the actuator was moving, if LS0, LS1 or LS2 must be ON as a condition for resuming actuator operation from the PLC, move the actuator to any target position.

Caution: These signals will turn OFF if a phase-A/B disconnection detection alarm occurs. z Notes on positioning band setting

The positioning band setting defines the range within which the position detected output signal turns

ON.

Condition for the position detected output signal to turn ON = Target position

± (Positioning band)

With any normal move command, once the position detected output signal turns ON the sequence processing will be executed and the move command input signal will turn OFF.

Take note that if the positioning band is wide and the move command input signal turns OFF quickly, the actuator may not reach the target position.

(Example) When the feed speed is 300 mm/s and deceleration is 0.3 G, the deceleration distance becomes approx. 15 mm.

If the positioning band is set to 30 mm, the position detected output signal will turn ON before the actuator starts decelerating.

In this case, promptly turning OFF the move command input signal on the PLC will cause the controller to initiate the deceleration stop processing.

Depending on the timing, therefore, the actuator may stop before the target position.

z Speed change during movement

If the load is made of soft material or is a bottle or otherwise topples easily due to its shape, one of the following two methods can be used to prevent the load from receiving vibration or impact when it stops:

[1] Reduce the deceleration to make the deceleration curve gradual.

[2] Initially move the actuator at the rated speed, and reduce the feed speed immediately before the target position.

Method [2], where the feed speed is reduced, is explained below.

(Example) Move the actuator from the rear end to the front end by using the intermediate point as a dummy point, where the feed speed is set to 300 mm/s until the intermediate point and then reduced to 20 mm/s after passing the intermediate point.

z Pause during movement

Since move commands are based on level mode, the actuator continues to move while a move command is ON. Once the move command turns OFF, the actuator will decelerate to a stop and complete the operation.

Therefore, turn OFF the move command if the actuator must be stopped temporarily as a low-degree safety measure.

(Example) Temporarily stop the actuator while it is moving to the front end.

Operation timings

PLC processing 1: Turn ON the rear end move command signal (ST0) upon occurrence of the emergency situation, and then turn OFF the front end move command signal (ST1).

8.2 Detail Explanation of Parameters

If a parameter has been changed, always restart the controller using a software reset command or by reconnecting the power.

8.2.1 Parameters Relating to the Actuator Stroke Range

z Soft limit (No.3/4 LIMM/LIML)

Set the soft limit in the positive direction in parameter No. 3, and that in the negative direction in parameter

No. 4.

The factory setting for the soft limits conforms to the effective actuator length. Change the settings, as necessary, to prevent crash with an obstacle or when the actuator must be stroked slightly beyond its effective length.

A wrong soft limit setting will cause the actuator to crash into the mechanical end, so exercise due caution.

The minimum setting unit is “0.01 [mm].”

(Note) To change a soft limit, set a value corresponding to 0.3 mm outside of the effective range.

Example) Set the effective range to between 0 mm and 80 mm

Approx. 0.1 mm

These parameters set the zone within which the zone output signal (ZONE1) turns ON when the selected

PIO pattern is “0” (standard type), “4” (7-point type) or “5” (3-point type).

The zone output signal turns ON when the current position is between the negative-side boundary and positive-side boundary. Set the positive-side boundary in parameter No. 1, and negative-side boundary in

No. 2.


Example) To turn ON the ZONE1 signal when the actuator with a 300-mm stroke enters the section of

100 to 200 mm, set 200.00 in parameter No. 1 (Zone boundary+) and 100.00 in parameter No.

(Note) This controller does not use parameter No. 23 (Zone boundary 2+) and parameter No. 24 (Zone boundary 2-).

125

z Home return direction (No.5 ORG)

Unless specified by the user, the home return direction is set to the motor direction at the factory.

Should a need arise to change the home direction after the actuator has been assembled into your system, reverse the setting in parameter No. 5 between “0” and “1.”

If necessary, also change the home return offset, soft limit and excited-phase signal detection direction parameters.

Caution: The home direction cannot be reversed for a rod-type actuator. z Home return offset (No.22 OFST)

The controller is shipped from the factory with an optimal value set in parameter No. 22, so the distance from each mechanical end to the home becomes uniform.


The home return offset can be adjusted in the following conditions:

[1] Want to align the actuator home and the system’s mechanical home after the actuator has been assembled into the system

[2] Want to set a new home after reversing the factory-set home direction

[3] Want to eliminate a slight deviation generated after replacing the actuator

Caution: If the home return offset has been changed, the soft limit parameters must also be adjusted accordingly.

8.2.2 Parameters Relating to the Actuator Operating Characteristics

z

PIO jog speed (No.26 IOJV)

When the selected PIO pattern is “1” (teaching type), this parameter defines the jog speed to be applied when jog input commands are received from the PLC.

The factory setting is “100 [mm/sec].”

Set an appropriate value in parameter No. 26 in accordance with the purpose of use.

The maximum speed is limited to “250 [mm/sec].”

(Note) Parameter No. 47 (PIO jog speed 2) is not used for this controller. z PIO inching distance (No.48 IOID)

When the selected PIO pattern is “1” (teaching type), this parameter defines the inching distance to be applied when inching input commands are received from the PLC.

The factory setting is “0.1 [mm].”

Set an appropriate value in parameter No. 48 in accordance with the purpose of use.

The maximum limit is limited to “1 [mm].”

(Note) Parameter No. 49 (PIO inching distance 2) is not used for this controller. z Default speed (No.8 VCMD)

The factory setting is the rated speed of the actuator.

When a target position is set in an unregistered position table, the setting in this parameter will be used as the speed data for the applicable position number.

To reduce the default speed from the rated speed, change the setting in parameter No. 8.

126

z Default acceleration/deceleration (No.9 ACMD)

The factory setting is the rated acceleration/deceleration of the actuator.

When a target position is written to an unregistered position table or the current position is read in the teaching mode, the setting in this parameter will be used as the acceleration/deceleration data for the applicable position number.

To reduce the default acceleration/deceleration from the rated acceleration/deceleration, change the setting in parameter No. 9. z Default positioning band (in-position) (No.10 INP)

The factory setting is “0.10 [mm].”

When a target position is written to an unregistered position table or the current position is read in the teaching mode, the setting in this parameter will be used as the positioning band data for the applicable position number.

Increasing the default positioning band will allow the position complete signal to be output early. Change the setting in parameter No. 10, as necessary. z Current-limiting value at standstill during positioning (No.12 SPOW)

The factory setting conforms to the standard specification of the actuator.

Increasing this setting will increase the holding torque at standstill.

This setting need not be changed in normal conditions of use. However, to prevent hunting caused by large external force applied while the actuator is at standstill, the value set in parameter No. 12 must be increased.

(Do not increase the value beyond 70%.) z Current-limiting value during home return (No.13 ODPW)

The factory setting conforms to the standard specification of the actuator.

Increasing this setting will increase the home return torque.

This setting need not be changed in normal conditions of use. However, if an increased slide resistance causes the home return to complete before the correct position depending on the affixing method, load condition or other factor when the actuator is used in a vertical application, the value set in parameter No.

13 must be increased.

(As a guide, the maximum limit is 100% for the RA3C/RA3D types and 75% for all other types.) z Home sensor input polarity (No. 18, LS)

This parameter is supported when a RCP2-RTB/RTC rotational axis is used in the home sensor mode.

Definition of settings : 0 (Sensor not used)

: 1 (Sensor polarity of contact a)

: 2 (Sensor polarity of contact b) z Speed override (No.46 OVRD)

Use this parameter when moving the actuator at a slower speed to prevent danger when the system is initially started for test operation.

When move commands are issued from the PLC, the moving speed set in the “Speed” field of the position table can be overridden by the value set by parameter No. 46.

Actual moving speed = [Speed set in the position table] x [Value of parameter No. 46]

÷ 100

Example) Value in the “Speed” field of the position table 500 (mm/s)

Value of parameter No. 46 20 (%)

Under the above settings, the actual moving speed becomes 100 mm/s.

The minimum setting unit is “1 [%],” while the input range is “1 to 100 [%].” The factory setting is “100 [%].”

(Note) This parameter is ignored for move commands from the PC and teaching pendant.

127

z Default direction of excited-phase signal detection (No.28 PHSP)

When the servo is turned on for the first time after the power on, excited-phase detection is performed

This parameter defines the direction of this detection.

The parameter need not be changed in normal conditions. In certain situations, such as when the actuator was contacting a mechanical end or obstacle when the power was turned on and cannot be moved by hand, change the direction to one that allows the motor to operate smoothly.

To do so, set parameter No. 28 to “0” or “1.” If the detection direction should be the same as the home return direction, specify the same value currently set in parameter No. 5 (Home return direction).

To set a direction opposite to the home return direction, specify the value different from the one currently set in parameter No. 5 (Home return direction).

(Example 1) Power was turned on when the slider was contacting the bottom mechanical end in a configuration where the actuator is installed vertically with the motor at the top.

Home return direction z Excited-phase signal detection time (No.29 PHSP)

Set different values.

When the servo is turned on for the first time after the power on, excited-phase detection is performed.

This parameter defines the time of this detection.

The parameter need not be changed in normal conditions, because a detection time appropriate for the standard specification of the actuator has been set at the factory.

Should an excitation detection error or abnormal operation occur when the servo is turned on for the first time after the power on, one remedial action that can be taken is to change the detection time set by parameter No. 29.

If you wish to change this parameter, contact IAI beforehand. z Safety speed (No.35 SAFV)

This parameter defines the feed speed to be applied during manual operation.

The factory setting is “100 [mm/sec].”

To change this speed, set an optimal value in parameter No. 35.

Take note that the maximum speed is limited to “250 [mm/s]” and that you should set a speed not exceeding this value.

128

z Automatic servo-off delay time (No.36 ASO1/No.37 ASO2/No.38 ASO3)

This parameter defines the delay time after the positioning is completed until the servo turns off automatically, when the “Standstill mode” field of the position table is set to “1,” “2” or “3” (automatic servooff control enabled) or parameter No. 53 (Default standstill mode) is set to “1,” “2” or “3”(automatic servooff control enabled).

Meaning of settings: 1: T becomes the value set by parameter No. 36.

2: T becomes the value set by parameter No. 37.

3: T becomes the value set by parameter No. 38.

The factory setting is “0 [sec].”

(Since no holding current flows, power consumption will decrease.)


Refer to the above timing chart.


The pulse motor is servo-controlled to reduce the holding current.

Although the exact degree of current reduction varies depending on the actuator model, load condition, etc., the holding current decreases to approx. 1/2 to 1/4.



129

z Push speed (No.34 PSHV)

This parameter defines the push speed to be applied after the actuator reaches the target position in push

& hold operation.

Before the shipment, this parameter has been set to the default value selected in accordance with the characteristics of the actuator.

Set an appropriate speed in parameter No. 34 by considering the material and shape of the load, and so on.

Take note that maximum speed is limited to “20 [mm/sec]” even on high-speed types and that you should use the actuator at push speeds not exceeding this level.

Speed Push speed

Load

Positioning band

Caution: It is recommended that you set the push speed to 5 [mm/s] or above to minimize the negative effect of push force variation. z Push completion judgment time (No.6 PSWT)

This parameter is used as a condition for determining that the load was contacted and the push & hold operation has completed.

As for the specific method of judgment, the push & hold operation is deemed to have completed if the current-limiting value set in the position table has been retained for the time set by parameter No. 6.

Set an optimal time matching the current-limiting value, by considering the material and shape of the load, and so on.

The minimum setting unit is “1 [msec],” while the maximum value is “9999 [msec].” The factory setting is

“255 [msec].”

(Note) The chart below explains how completion of push & hold operation is determined if the load shifted during the judgment and the current has changed as a result, based on a judgment time of

255 msec.

Push current

Starting position Target position Counting starts.


The count decreases to 180.


Push & hold operation is deemed to have completed.

If the motor current remains at or above the push current for 200 msec and then drops below this level for

20 msec, the count will decrease by 20. When the push current is reached again thereafter, counting will start from 180. If the motor current remains at or above the push current for 75 msec, the count will increase to 255 and thus push & hold operation will be deemed to have completed.

In total, 295 msec was required for the judgment.

z Enable function (No.42 FDIO4)

Whether to enable or disable the deadman switch function on an ANSI-type teaching pendant is defined by parameter No. 42.

* An ANSI-type teaching pendant will be developed in the future.

Setting

Enable (Use) 0

Disable (Do not use) 1

The factory setting is “1 [Disable].” z Polarity of home check sensor input (No.43 AIOF)

The home check sensor is not included in the standard specification, but it can be installed as an option.

Normally this parameter need not be changed, but if the customer wishes to change the mode after the shipment, change the value of Parameter No. 43.

Definition of settings: 0 (Standard specification without home check sensor)

1 (Use the home check sensor based on contact-a sensor polarity)

2 (Use the home check sensor based on contact-b sensor polarity)

[Explanation of operation]

[1] When a home return command is issued, the actuator moves until contacting the mechanical end.

Upon contact with the mechanical end, the home check sensor signal is detected.

[2] Next, the actuator reverses its direction and stops at the home position.

[3] The controller determines that the movement has completed successfully if the home check sensor signal had changed when the actuator stopped. If the sensor signal remains the same, the controller recognizes that “position deviation” has occurred, in which case the controller will generate a “Home sensor not detected” error and output an alarm signal.

Mechanical end

Home check sensor

Home position z Load output judgment time (No.50 LDWT)

Power on position

If the torque check function is used in push & hold operation, the load output (LOAD signal) will turn ON when a specified condition is met. Since the command torque does not remain constant but fluctuates within a certain band while the actuator is moving, whether or not to turn ON the load output is determined based on whether the total duration of periods in which the command torque has exceeded the threshold corresponds at least to a specified time. This specified time is set using this parameter. The default value is “255 msec.”

131

z Torque check range (No.51 TRQZ)

This parameter sets whether or not to use the check range when determining if the threshold has been exceeded. The default value is “0,” i.e., to enable the check range.

Setting

Enable (Use the check range to make judgment) 0

Disable (Do not use the check range to make judgment) z Ball screw lead length (No.77 LEAD)

This parameter defines the ball screw lead length.

A default value appropriate for the characteristics of the actuator is set at the factory. z Axis operation type (No.78 ATYP)

This parameter defines the type of the actuator used.

Definition of settings : 0 (Linear axis)

: 1 (Rotational axis) z Rotational axis mode selection (No.79 ATYP)

If the axis operation type (No. 78) is set to “rotational axis,” selecting the index mode will fix the current value to a range of 0 to 359.99. If the index mode is selected, shortcut control can be used.

Definition of settings : 0 (Normal mode)

: 1 (Index mode)

Caution: Push & hold operation cannot be performed in the index mode. If push action data is entered in the position data, the data will be disabled and the actuator will perform normal movement.

The positioning band will correspond to the default positioning band set by the applicable parameter. z Shortcut selection for rotational axis (No.80 ATYP)

Set this parameter if you want to rotate the rotational axis in a specific direction.

“Shortcut” refers to a type of operation in which the actuator moves to the next point by taking the shortest path.

In addition to the normal positioning mode, the user can also select the teaching mode in which the actuator can be jogged via commands from a PLC and the current actuator position can be written to a specified position.

(Note 1) Jog commands from a PLC are also accepted in the positioning mode.

(Note 2) Positions can be rewritten by approximately 100,000 times.

The number of positioning points is increased to 512, so no zone output is available.

7-point type

The number of positioning points is limited to seven to offer separate direct command inputs and movement complete outputs for respective positions.

PLC ladder sequence circuits can be designed easily.

3-point type


Movement complete output signals function differently in this type, compared to the 7point type.

Specifically, the signal functions not only to “indicate movement complete,” but also to

“detect a position” in the same manner as auto-switches of an air cylinder. Push & hold operation cannot be performed.

134

z Movement command type (No.27 FPIO)

When the PIO pattern is set to “7-point type,” define the operation condition of the movement command input (ST0 to ST6) in parameter No. 27.

The factory setting is “0 [Level mode].”

Description of the movement command input Setting

Level mode:

The actuator starts moving when the input signal turns ON. When the signal turns OFF during the movement, the actuator will decelerate to a stop and complete its operation.

0

Edge mode:

The actuator starts moving when the rise edge of the input signal is detected. The actuator will not stop even when the signal turns OFF during the movement, until the target position is reached.

z Output mode of position complete signal (No.39 FPIO)

This parameter is effective when any PIO pattern other than “5” [3-point type] is selected.

It defines the status of completed position number signals [PM1 to PM256], movement complete signals at respective positions [PE0 to PE6] and position complete signal [PEND] to be applied if the servo turns off or “position deviation” occurs while the actuator is standing still after completing positioning.

The following two conditions can be considered:

[1] The position has deviated, due to external force and while the servo was on, beyond the value set in the “Positioning band” field of the position table.

[2] The position has deviated, due to external force and while the servo was off, beyond the value set in the “Positioning band” field of the position table.

This parameter is provided to permit flexible specification of how the “position complete status” is monitored in accordance with the characteristics of the system or sequence circuit on the PLC side.

The ON/OFF status of each position complete signal is controlled as follows in accordance with the setting of parameter No. 39.

Setting of parameter No. 39

0 [PEND]

Definition of completed position number signals [PM1 to PM256], movement complete signals at respective positions [PE0 to PE6] and position complete signal

[PEND]

[1] The servo is on

The signal remains ON even after the current position has exited the range set by

1 [INP] the “Positioning band” field of the position table, with respect to the target position.

[2] The servo is off

The signal is OFF unconditionally regardless of the current position.

Regardless of the servo on/off status, the signal turns ON if the current position is within the range set by the “Positioning band” field of the position table, with respect to the target position, and turns OFF if the current position is outside this range.

* In this mode, the applicable signals are used as limit switches.

The factory setting is “0 [PEND].” z SIO communication speed (No.16 BRSL)

Set the communication speed to be used when the control is performed via serial communication using the PLC’s communication module.

Set an appropriate value in parameter No. 16 in accordance with the specification of the communication module.

One of 9600, 19200, 38400 and 115200 bps can be selected as the communication speed.

The factory setting is “38400 [bps].” z

Minimum delay time for slave transmitter activation (No.17 RTIM)

This parameter defines the minimum delay until the controller’s transmitter will be activated after completion of command reception, when serial communication is performed using the PLC’s communication module.

The factory setting is “5 [msec],” but other necessary delay time must be set in parameter No. 17 if the specification of the communication module exceeds 5 msec.

137

z Silent interval multiplier (No.45 SIVM)

This parameter is not used for this controller. It is applied to controllers of RS485 serial communication type.

If specified, this parameter defines the multiplier to be applied to the silent interval time for delimiter judgment in the RTU mode.

The default setting is the communication time corresponding to 3.5 characters in accordance with the

Modbus specification.

This setting need not be changed for normal operations performed with a PC or teaching pendant.

If the scan time of the PLC is not optimal and the character transmission interval exceeds the silent interval, the silent interval time can be extended using parameter No. 45.

The minimum setting unit is “1 [time],” while the input range is “0 to 10.” If “0” is set, no multiplier is applied.

138

Gain

Before the shipment, the servo has been adjusted in accordance with the standard specification of the actuator. Accordingly, the servo settings need not be changed in normal conditions.

Nonetheless, the parameters relating to servo adjustment are made accessible by the customer so that speedy actions can be taken in situations where vibration or noise occurs due to the affixing method of the actuator, load condition, or the like.

In particular, custom types (having a longer ball screw lead or stroke than standard types) are more vulnerable to vibration and noise due to external conditions.

In these circumstances, the following parameters must be changed. Contact IAI for details. z Servo gain number (No.7 PLG0)

7 5 rad/sec 0 ~ 31 6

This parameter determines the response when a position control loop is used.

Increasing the set value improves the tracking performance with respect to the position command.

However, increasing the parameter value excessively increases the chances of overshooting.

If the set value is small, the tracking performance with respect to the position command drops and positioning takes a longer time.

Speed

Set value is large (overshooting).

Set value is small.

z

Speed loop proportional gain (No.31 VLPG)

Time

31 --- 1 ~ 27661

Default


This parameter determines the response when a speed control loop is used.

Increasing the set value improves the tracking performance with respect to the speed command (i.e., servo rigidity increases).

The greater the load inertia, the larger this parameter value should be.

However, increasing the parameter value excessively makes the actuator more vulnerable to overshooting or shaking, leading to mechanical vibration.

Default


This parameter determines the response when a speed control loop is used.

Increasing the set value lowers the response with respect to the speed command, while also decreasing the reactive force that generates upon load change.

Decreasing the parameter value excessively makes the actuator more vulnerable to overshooting or shaking, leading to mechanical vibration.

If the set value is small, the tracking performance with respect to the position command drops and positioning takes a longer time.

Speed

Set value is small. (overshooting).

Set value is large z Torque filter time constant (No.33 TRQF)

Time

33 --- 1 ~ 2500

Default


This parameter determines the filter time constant for torque commands.

If the resonance frequency of the machine is smaller than the response frequency of the servo loop, the motor vibrates.

This mechanical resonance can be suppressed by increasing the value set in this parameter.

However, increasing the parameter value excessively may reduce the stability of control.

10. Troubleshooting

10.1 Action to Be Taken upon Occurrence of Problem

Upon occurrence of a problem, take an appropriate action according to the procedure below in order to ensure speedy recovery and prevent recurrence of the problem. a. Check the status indicator lamps.

SV (green) --- The servo is ON.

ALM (red) --- An alarm is present, or an emergency stop has been actuated or the motor drive power is cut off. b. Check for error in the host controller. c. Check the voltage of the main 24-VDC power supply. d. Check the voltage of the 24-VDC power supply for I/O signals. e. Check for alarm.

Confirm the details of error on the PC or teaching pendant. f. Check the cables for connection error, disconnection or pinching.

Before performing a continuity check, turn off the power (to prevent a runaway actuator) and disconnect the cables (to prevent accidental power connection due to a sneak current path). g. Check the I/O signals. h. Check the noise elimination measures (grounding, installation of surge killer, etc.). i. Review the events leading to the occurrence of problem, as well as the operating condition at the time of occurrence. j. Check the serial numbers of the controller and actuator. k. Analyze the cause. l. Take

Please check items a through j before contacting IAI.

(Note) The *ALM output signal is a contact-b signal.

After the power is turned on, this signal will remain ON while the controller is normal, and turn

OFF if an alarm occurs.

Although the *ALM signal will turn OFF when the power is cut off, it cannot be used as a contact-b interlock.

How to reset operation-cancellation level alarms

Input an alarm reset signal (RES) continuously for 6 msec or more.

This resets the *ALM signal to ON, so turn OFF the RES signal after confirming that the *ALM signal is

10.4 Alarm Description and Cause/Action

(1) Message level alarms signal during movement

Cause/Action

Cause: The current-position write signal (PWRT) was input in the teaching mode while the actuator was jogging.

Action: Input the PWRT signal after confirming that the jog button is not pressed and the actuator is stopped (MOVE output signal is OFF).

signal before completion of home return

0A1 Parameter data error Cause: The input range of parameter range data is not appropriate.

(Example) This error occurs when the magnitude relationship of a pair of range parameters is inappropriate, such as when the value of soft limit- is mistakenly set to 300 mm when the value of soft limit+ is 200.3 mm.

Action: Change the parameters to appropriate values.

0A2 Position data error

Cause: The current-position write signal (PWRT) was input in the teaching mode when home return was not yet completed.

Action: Input the HOME signal first to perform home return, and then input the PWRT signal after confirming that home return has completed (HEND output signal is ON).

Cause: [1] A move command was input when no target position was set in the “Position” field.

[2] The target position in the “Position” field exceeds a soft limit setting.

[3] An incremental target position was specified in the “Position” field in the 3-point type.

Action: [1] Set a target position first.

[2] Change the target position to a value inside the soft limit setting.

[3] Specify an absolute target position.

0A7 Deceleration command error

If a position command is issued while the actuator is moving where the target position corresponding to the position number is located near a soft limit and the deceleration is also set low, the actuator may move past the soft limit.

Deceleration starting position not resulting in soft limit overshoot

If a command is issued here, soft limit overshoot will occur.

Soft limit

Cause: When the speed was changed during movement, the next move command was not issued quick enough.

Action: Quicken the speed change timing so that the actuator will not overshoot the soft limit.

149

0B6 Phase-Z timeout

Cause/Action

Cause

Phase Z could not be detected within the phase-Z output status detection time set in the simple absolute unit.

[1] When the detail code is H’0001

A timeout occurred during the pole sensing operation performed in conjunction with magnetic pole check operation.


A timeout occurred while the actuator was operating after reversing its direction upon contacting the load in a home return.

Action

• Check the wiring condition of the motor relay cable.

• Check the wiring condition of the brake cable, and also turn on/off the brake release switch and check if the brake makes “click” sounds.

• Check the assembly condition of mechanical parts for any abnormality.

• Move the actuator away from the mechanical ends, and then reconnect the power.

• If the payload is normal, turn off the power and move the actuator by hand to check the slide resistance. sensor detected

This error indicates that the actuator equipped with the home check sensor has not yet successfully completed the home return operation.

Cause: [1] The load contacted any surrounding equipment or structure during home return.

[2] The slide resistance of the actuator is high in some location.

[3] The home check sensor is not properly installed, faulty or open.

Action: If the load is not contacting any surrounding equipment or structure, [2] or [3] is suspected. Please contact IAI.

0BE Home return timeout Cause: Home return does not complete after elapse of the time set by the applicable manufacturer’s parameter following the start of home return operation. (This error does not occur in normal operations.)

Action: The controller and actuator combination is wrong, among others.

Please contact IAI.

0C0 Excessive speed

0C1 Servo error

Cause: The motor speed exceeded the maximum level set by the applicable manufacturer’s parameter. Although this error does not occur in normal operations, it may occur if the load decreased before a servo error was detected and the actuator moved quickly as a result, which can be caused by various reasons including the following:

[1] The slide resistance of the actuator is high in some location.

[2] The load increased due to momentary application of external force.

Action: Check the assembly condition of mechanical parts for any abnormality.

If the actuator itself is suspected as the cause, please contact IAI.

This error indicates that the motor could not be operated for 2 seconds or more after the move command was accepted and before the target position was reached.

Cause: [1] The motor relay cable connector is loose or open.

[2] If the actuator is equipped with a brake, the brake cannot be released.

[3] The load increased due to application of external force.

[4] The slide resistance of the actuator itself is high.

Action: [1] Check the wiring condition of the motor relay cable.

150

power-supply overvoltage

0CA Overheating

Cause/Action

[2] Check the wiring condition of the brake cable. Also, turn on/off the brake release switch and check if the brake makes “click” sounds.

[3] Check the assembly condition of mechanical parts for any abnormality.

[4] If the payload is normal, turn off the power and move the actuator by hand to check the slide resistance.

If the actuator itself is suspected as the cause, please contact IAI.

This error indicates that the motor power-supply voltage is excessively high

(24 V + 20%: 28.8 V or above).

Cause: [1] The 24-V input power-supply voltage is high.

[2] A faulty part inside the controller.

Action: Check the input power-supply voltage.

If the voltage is normal, please contact IAI.

This error indicates that the temperature around the power transistor in the controller is excessively high (95

°C or above).

Cause: [1] The ambient temperature is high.


Action: [1] Lower the ambient temperature.

If [1] does not apply, please contact IAI. power-supply overvoltage

This error indicates that the 24-V input power-supply voltage is excessively high (24 V + 20%: 28.8 V or above).

Cause: [1] The 24-V input power-supply voltage is high.



If the voltage is normal, please contact IAI. power-supply voltage low

This error indicates that the 24-V input power-supply voltage is low (24 V

- 20%: 19.2 V or below).

Cause: [1] The 24-V input power-supply voltage is low.



If the voltage is normal, please contact IAI.

0D8 Deviation overflow stroke overtravel error

The position deviation counter has overflowed.

Cause: [1] The speed dropped during movement due to the effect of an external force, etc.

[2] The pole sense detection operation after power on is unstable.

Action: [1] Check the load conditions—such as whether the load is contacting a surrounding object or the brake is disengaged— and then correct the abnormality, if any

[2] An overload condition is suspected, so review the load weight.

Cause: [1] The actuator installed vertically overshot and exceeded a software stroke limit due to a large load or high deceleration setting when the target position was set to a point near the software stroke limit.

[2] The actuator was moved to outside the software stroke limits with the servo turned off, and then the servo was turned on.

Action: [1] Set the deceleration curve properly so that the actuator will not overshoot when stopping.

[2] Return the actuator to inside the software stroke limits, and then turn on the servo.

151

0DC Out of push & hold operation range error memory write verification error memory write timeout

Cause/Action

This error occurs when the actuator was pushed back to the target position due to an excessive push force after completion of push & hold operation.

Review the entire system.

When data has been written to the nonvolatile memory, the written data is read again to check (verify) if it matches the original data.

This error indicates that the two data do not match.

Cause: [1] Faulty nonvolatile memory

[2] The memory has been rewritten more than 100,000 times.

(The nominal rewrite limit of the nonvolatile memory is around

100,000 times.)

Action: If the alarm generates again after reconnecting the power, please contact IAI.

This error indicates that response is not received within the specified time after data was written to the nonvolatile memory.




100,000 times.)

(2) Cold-start level alarms

0B8 Pole sense error

0E5 Encoder error

0E8 Phase-A/B disconnection detection

0E9 Phase-A disconnection detection

0EA Phase-B disconnection detection

Cause/Action

This controller performs excited-phase detection when the servo is turned on for the first time after the power on. This error indicates that the specified encoder signal level could not be detected after excitation for the time set by parameter No. 29 (Excited-phase signal detection time).

Cause: [1] Loose or disconnected motor-relay cable connector

[2] Brake cannot be released on a controller equipped with brake.

[3] Large motor load due to application of external force

[4] Power was input when the actuator was contacting a mechanical end.

[5] Large slide resistance of the actuator itself

Action: [1] Check the wiring condition of the motor relay cable.

[2] Check the wiring condition of the brake cable, and also turn on/off the brake release switch to see if the brake makes

“click” sounds.

[3] Check for abnormality in the assembly condition of mechanical parts.

[4] Move the actuator away from the mechanical end and then reconnect the power.

[5] If the load is normal, cut off the power and move the actuator by hand to check the slide resistance.

If the actuator is suspected to be the cause, please contact IAI.

Cause:

[1] The controller was powered up before the simple absolute unit when the 24-V power supply was turned on.


The controller cannot communicate with the simple absolute unit properly due to noise, etc.


The controller cannot communicate with the simple absolute unit properly due to encoder cable disconnection, etc.

Action:

[1] Make sure the simple absolute unit is powered up before the controller

(or at least the two are powered up simultaneously).

[2] Change the installation location of the controller. Provide noise elimination measures such as setting a frame ground, noise filter or clamp filter.

[3] Check the encoder relay cable connecting the controller and simple absolute unit to see if the connectors are loose. Or, replace the cable.

Encoder signals cannot be detected correctly.

Cause:

[1] Loose or disconnected encoder-relay cable connector

[2] Piano switch 4 on the simple absolute unit is not set correctly.

[3] If a RA10C actuator is used together with an actuator or actuators of other type, the encoder cables may not be connected in the correct combination.

Action:

[1] Check for loose or disconnected connector.

[2] Check if the settings conform to 5.1.1, “Piano Switch Settings” in the operation manual for the simple absolute unit.

153

error (1)

0EE Absolute error (2)

0EF Absolute error (3)

Cause/Action

[3] Check the model name of the encoder cable.

(Encoder cable connecting the simple absolute unit and actuator)

Note) This action is applicable only to RCP2 series controllers.

Cable for RA10C type: CB-RFA-*

Other actuators: CB-RCP2-*

Cause:

[1] When the power was reconnected after completion of an absolute reset, the current position changed due to an external factor or for other reason while the absolute unit was communicating with the controller.

[2] When an absolute reset was performed, the current position changed due to an external factor or for other reason while the simple absolute unit was communicating with the controller.

Action:


Turn off the power, make sure the actuator is not receiving vibration, etc., and then turn the power back on.


Make sure the actuator is not receiving vibration, etc., and then perform a home return operation again.

Cause:

[1] The power was turned on for the first time after connecting the battery to the simple absolute unit.


The battery voltage dropped to a level at which the encoder counter in the simple absolute unit could no longer retain the count.


The encoder connector was unplugged during a power outage, or the encoder cable was disconnected.


A parameter was changed.

Action:

If [1], [2] or [4] is suspected as the cause, perform an absolute reset by referring to the operation manual for the simple absolute unit (5.2,

“Absolute Reset Method”).

[2] Supply power for at least 48 hours to charge the battery fully, and then perform an absolute reset.

Cause:

The current value changed at a speed equal to or greater than the specified rotational speed due to an external factor or for other reason while the power was cut off.

Action:

Change the speed setting in the simple absolute unit and also implement measures to prevent the actuator from moving at a speed equal to or above the specified setting while the power is cut off.

If the battery backup time is more than sufficient, try setting a higher motor speed.

See also: 5.1.1, “Piano Switch Settings” in the operation manual for the simple absolute unit.

If this error occurred, perform an absolute reset by following the specified procedure (5.2, “Absolute Reset Method”).

154

0F4 Unmatched PCB

0F8 Damaged memory

0FA CPU error

Cause/Action

This controller uses a different motor drive circuit depending on the motor capacity, and thus adopts a different printed circuit board (PCB) appropriate for each motor capacity.

For this reason, whether the motor type set by the applicable manufacturer’s parameter matches the board is checked in the initialization process after startup.

This error indicates that the two do not match.

Cause: The parameter was not entered correctly or the correct board was not assembled.

Action: Should this error occur, please contact IAI.

Abnormal data was detected during the nonvolatile memory check after starting.




100,000 times.)


The CPU is not operating properly.

Cause: [1] Faulty CPU

[2] Malfunction due to noise

10.5 Messages Displayed during Operation Using the Teaching Pendant

This section explains the warning messages that may be displayed during operation using the teaching pendant.

Description

112 Invalid data

113

114

Value too small

Value too large return completion

117 No movement data

An inappropriate value was entered in a parameter.

(Example) 9601 was entered as the serial communication speed by mistake.

Enter an appropriate value again.

The entered value is smaller than the setting range.

The entered value is larger than the setting range.

Refer to the actuator specifications or parameter table and enter an appropriate value again.

The current position was written when home return was not yet completed.

Execute home return again.

Target position is not set under the selected position number.

Enter the target position first.

11E Paired data mismatch

11F Absolute position too small The minimum movement toward the target position is determined by the lead length of the drive system and resolution of the encoder.

This message indicates that the entered target value is smaller than the minimum movement.

(Example) If the lead length is 20 mm, the encoder’s resolution is

800 pulses and accordingly the minimum movement becomes 20

÷ 800 = 0.025 mm/pulse.

In this case, this message will be displayed if 0.02 mm is entered as the target position.

121 Push & hold search end over

The values indicating the magnitude relationship of a pair of data are inappropriate.

(Example) The same value was entered in both the parameters for + and – soft limits.

Enter appropriate values again.

The final position in push & hold operation exceeds the soft limit.

This has no negative effect if the actuator contacts the load. If the actuator misses the load, however, the soft limit will be reached and thus this message is displayed as a warning.

Change either the target position or positioning band.

122 Multiple axes connected at assignment

157

30C No connected axis

Description

This message indicates that no controller address is recognized.

Cause: [1] The controller is not operating properly.

[2] Only the supplied communication cable (SGA/SGB) is disconnected.

[3] If a SIO converter is used, 24V is supplied to the converter but the link cable is not connected.

[4] The ADRS switch settings are duplicated by mistake when multiple controllers are linked.

Action: [1] Check if the RDY lamp on the controller is lit. If the lamp is not lit, the controller is faulty.

[2] If a spare teaching pendant is available, replace the current pendant with the spare unit, or with a PC, and see if the message disappears.

[3] Supply power after connecting the link cable between the converter and controller.

[4] Make sure the ADRS switch settings are not duplicated.

If the message is still displayed after taking the above actions, please contact IAI.

158

10.6 Specific Problems

z I/O signals cannot be exchanged with the PLC.

Cause: [1] The 24-V I/O power supply is connected in reverse.

[2] If the problem is with an output circuit, a circuit component may have been damaged due to a large load that caused the current flowing into the circuit to exceed the maximum current.

[3] Contact failure in the connector or relay terminal block on the PLC end.

[4] Contact failure between the female pins in the flat cable connector and the male pins on the controller due to expanded female pins.

Action: Check the connection condition of the power supply and connector, as well as the load on the output side.

If the cause is identified as [1] or [2], the controller must be replaced. If there is a possibility of

[4], the flat cable must be replaced. Please contact IAI.

Warning: When performing a continuity check of the flat cable, pay due attention not to expand the female pins in the connector. It may cause contact failure and disable normal operation of the controller. z The ALM lamp illuminates when the power is input.

(An alarm is present, or an emergency stop has been actuated or the motor power cut off.)

* If the ALM output signal is OFF, an alarm is present. Connect a PC or teaching pendant to check the nature of the error and then remove the cause.

* If the ALM output signal is ON, the emergency stop circuit has been actuated. Check the following points, among others:

[1] Is the emergency-stop switch on the operation panel pressed or any necessary interlock released?

[2] Is the emergency-stop switch on the teaching pendant pressed?

[3] Is parameter No. 42 (Enable function) enabled by mistake by connecting a teaching pendant not supporting the enable switch?

[4] If multiple controllers are connected, is the crossover wiring correct? z The SV lamp does not illuminate when the servo ON signal is input after the power was input.

(The servo does not turn ON.)

Cause: [1] Contact failure of the flat cable

[2] Faulty controller

Check the servo ON signal (SON) on the I/O monitor screen of the PC or teaching pendant.

If the signal is input, probably the controller is faulty. Please contact IAI.

159

z Home return ends in the middle in a vertical application.

Cause: [1] The load exceeds the rating.

[2] The ball screw is receiving torsional stress due to the affixing method of the actuator, tightening of bolts only on one side, etc.

[3] The slide resistance of the actuator itself is large.

Action: [1] Increase the value set in parameter No. 13 (Current-limiting value during home return).

Increasing the parameter value will increase the home return torque. As a guide, however, remember that the maximum limit is 100% for the RA3C/RGD3C types and 75% for all other types.

[2] Loosen the fixing bolts and check if the slider moves smoothly.

If the slider moves smoothly, review the affixing method and bolt tightening condition.

[3] If the slide resistance of the actuator itself is large, please contact IAI. z Noise occurs during downward movements in a vertical application.

Cause: The load exceeds the rating.

Action: [1] Decrease the speed.

[2] Decrease the value set in the parameter No. 7 (Servo gain number). Do not decrease the parameter setting below “3.” z Vibration occurs when the actuator is stopped.

Cause: The slider is receiving an external force.

Action: If the external force cannot be removed, increase the value set in parameter No. 12 (Currentlimiting value at standstill during positioning).

Increasing this value will cause the holding torque at standstill to increase, so do not increase the parameter setting above 70%. z The actuator overshoots when decelerated to a stop.

Cause: The load inertia is high due to an inappropriate balance of load and deceleration.

Action: Decrease the acceleration/deceleration setting. z The home and target positions sometimes shift.

Cause: [1] The encoder waveform is disturbed by the effect of noise.

[2] In the case of a rod-type actuator, the non-rotation accuracy increased due to application of rotating moment to the rod.

Action: [1] Check if the grounding is implemented correctly. Also check for any equipment being a potential noise source.

[2] The actuator may have to be replaced in some cases. Please contact IAI. z The speed is slow during push & hold operation.

Cause: The set current-limiting value is low with respect to the load and slide resistance.

Action: Increase the current-limiting value for push & hold operation. z The actuator moves only a half of, or twice as much as, the specified movement.

Cause: [1] The combination of controller and actuator is wrong.

The lead length of the ball screw varies depending on the actuator type, so a wrong combination will cause the movement and speed to change.

[2] Factory setting error at IAI

Action: [1] If multiple actuators of different types must be used, confirm using the identification labels, etc., that the correct actuator is connected to the controller.

[2] Please contact IAI.

160

z A servo error occurred while the actuator was moving (ROBO Gripper).

Cause: The load was not positioned properly and contacted the finger attachment in the positioning mode.

Action: Adjust the starting position of push action and the thickness of finger attachment (including buffer material) by considering a possible offset of load position, so that the load can be clamped properly in the push & hold mode.

Immediately after recovery from the error, the feed mechanism may still be locked. Be sure to turn the open/close screw to loosen each finger attachment before resetting the alarm.

Caution: If the servo ON signal is disabled or the alarm is reset while the servo ON signal is still

ON, the servo will remain ON.

If the open/close screw is turned in this condition, the screw will return automatically and the lock cannot be released. Therefore, reissuing a movement command will cause the alarm to generate again.

[2-finger type]

Open/close screw

Turn the screw counterclockwise using a flathead screwdriver.

[3-finger type]

Remove one finger attachment and take out the load first, and then turn the open/close screw clockwise.

Remove one finger attachment.

Open/close screw

Turn the screw clockwise.

Opening direction

161

z Abnormal operation results when the servo is turned ON after the power ON.

Cause: Excitation phase detection was not performed correctly when the servo was turned ON, because one of the following conditions existed when the power was input:

[1] The slider or rod was contacting the mechanical end.

[2] The load was being pushed by a strong external force.

Action: [1] Check if the slider or rod is contacting the mechanical end.

If the slider/rod is contacting the mechanical end, move it away from the mechanical end.

If the actuator is equipped with a brake, move the slider/rod after turning ON the brake release switch to forcibly release the brake.

At this time, exercise caution not to allow the load to drop suddenly due to its own weight.

Your hand may be caught by the dropped load or the robot hand or load itself may be damaged.

If the actuator cannot be moved by hand, one possible solution is to check the direction of excited-phase signal detection and change the direction if necessary. If you wish to use this method, consult IAI beforehand.

For details, refer to the applicable parameter in 8.2.2, “Parameters Relating to Actuator

Operating Characteristics.”

[2] Check if the load is contacting any surrounding part.

If the load is contacting any surrounding part, provide a clearance of 1 mm or more from the applicable part.

If the checks in [1] and [2] did not find any problem, please contact IAI. z The SV lamp blinks.

The automatic servo-off mode is active. (This is not an error or fault.)

z Fault check and replacement of the cooling fan

A cooling fan is installed in the large-capacity type (PCON-CF).

To check if the fan is faulty, or when replacing the fan, follow the procedure below:

1) Unplug all connectors and wires connected to the controller, and take out the controller.

Appendix

Remove all cables except for the MPI/MPO jumper wire.

2) Remove the resin case.

• The cutout holes in the resin case are engaged with the hooks on the mounting base plate. Use a screwdriver, etc., to release the case from each hook, and push the mounting base plate upward.

• Pull out the resin case.

172

3) Check if the fan is normal.

Appendix

Check method:

[1]

Connect the power cable to the 24-V and 0-V terminals on the power-supply terminal block.

[2]

Turn on the power to check if the fan operates.

If the fan is normal, it should operate for approx.

2 seconds.

If the fan is faulty, it will not operate.

(Note) To extend the service life of the fan, a temperature sensor is used to detect the temperature around the power transistor. The fan will operate when the detected temperature reaches

60

°C or above, and stop when the temperature drops to 50°C or below.

Because of this specification, the fan is designed to operate for approx. 2 seconds when the power is turned on to allow the user to check if the fan is faulty.

4) If the fan is faulty, replace it after cutting off the power.

[1] Remove the fan.

Remove the flat countersunk head screws

(M3x5 x 2 pcs).

Pull out the connector by hand.

Remove the pan head screws

(M3x12 x 2 pcs).

Removed fan and mounting bracket

[2] Install a new fan to the mounting bracket, plug in the connector, and affix the mounting bracket using the flat countersunk head screws.

(Reference) Tightening torque for pan head screws: 61.5 N•cm (6.27 kgf•cm)

[3] To make sure, turn on the power to confirm that the fan operates.

5) Turn off the power and pull out the power cable.

6) Install the resin case. Engage the cutout holes in the resin case with the hooks on the mounting base plate.

7) Plug in the connectors and cables back to their original conditions.
