Introduction
1. Overview
1.1
Overview
This product is a pulse-train input controller used exclusively with RCP2 actuators.
It can control actuators using the positioning control function of the host controller (PLC).
This controller also provides power-saving functions to address the growing need for saving energy.
The key features and functions of this controller are summarized below.
„ Dedicated Homing Signal
This signal supports IAI’s original homing operation based on push motion at the stroke end.
With this signal, homing can be performed automatically without having to program a complex sequence or using
an external sensor, etc.
„ Brake Control Function
The electromagnetic brake power is supplied internally from the controller. However, 24 V must be supplied
externally to forcibly release the brake when the servo is off.
„ Torque Limiting Function
This controller lets you limit torque using an external signal (set by a parameter). A signal is output when the
specified torque is reached. This function enables push-motion operation, press-fit operation, etc.
„ Full Servo Control Function
The holding current can be reduced via servo-control of the pulse motor.
Although the exact level of current reduction varies in accordance with the actuator type and load condition,
normally the holding current drops to approx. one-half to one-fourth.
When actually starting your system or if you have encountered any problem, also refer to the manuals for the actuator,
teaching pendant, PC software and/or any other component you are using, in addition to this manual.
This manual does not cover all possible deviations from normal operations or unexpected phenomena such as
complex signal changes resulting from critical timings.
Therefore, the reader should assume that items not described in this manual are “not permitted,” as a rule.
*
This manual has been prepared with the utmost attention to ensure accuracy and completeness. However, there
may still be inaccuracies and omissions. Should you find any inaccurate description or if you have any comment,
please contact IAI.
Keep this manual in a convenient place so that you can easily reference it whenever necessary.

Cautions on wiring method
Use a twisted cable to connect the 24-VDC external power supply.
Separate the controller wiring from high-power lines of motive power circuits, etc. (Do not tie them together or place in
the same cable duct.)
If you want to extend the motor or encoder cable beyond the length of the supplied cable, contact IAI.
(2) Noise sources and elimination
Noise generates from many sources, but the most common sources of noise you should consider when designing a
system are solenoid valves, magnet switches and relays. Noise generation from these components can be prevented
by the method explained below.
AC solenoid valves, magnet switches, relays
Method --- Install a surge absorber in parallel with the coil
Point
Connect to each coil over the shortest possible wiring distance.
When a surge absorber is installed on the terminal block, etc., its noise
elimination effect will decrease if the distance from the coil is long.

Heat Radiation and Installation
Fan
3. Installation and Wiring
Design the control panel size, controller layout and cooling method so that the temperatures around the controller will
always be kept to 40?C or below.
Mount the controller vertically on the wall, as shown below. Since cooling is provided by means of natural convection,
follow this orientation and provide a minimum clearance of 50 mm above and below the controller to allow sufficient
airflows to circulate.
If you are installing multiple controllers side by side, provide a fan on top of the controllers to agitate the airflows as
an effective way to keep the surrounding temperatures constant.
Provide a minimum clearance of 80 mm between the front face of the controller and the wall (cover).
At least 50 mm
At least 80 mm

Recognition of Input Signals
4. Operation Using I/O Signals
The input signals of this controller have an input time constant to prevent malfunction due to chattering, noise, etc.
Each input signal is switched when the new signal state has continued for at least 6 msec.
In other words, when the input is switched from OFF to ON, the controller will recognize that the input signal is ON after
6 msec. The same applies when the input is switched from ON to OFF.
* Excluding command pulse input (PP•/PP, NP•/NP).

Notes on the ROBO Gripper
4. Operation Using I/O Signals
(1) Finger Operation
[1] Definition of position
With the two-finger type, the stroke specification indicates the total sum of travels by both fingers. In other
words, the travel by one finger is one-half this stroke.
A position is specified as a travel by one finger from the home position toward the closing direction.
Therefore, 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 one finger.
With the two-finger type, the relative speed and acceleration are double the command values, respectively.
[3] Gripper operation mode
In applications where the work is to be gripped, be sure to use the “push-motion mode.”

„ Servo-on Command Input (SON)
The servo remains on while this signal is ON.
The actuator can be operated while the SON signal is ON.
While this signal is OFF, the actuator does not operate even when the controller power is supplied.
If the SON signal is turned OFF while the actuator is operating, the actuator will decelerate at the forced-stop torque
until it stops. After the actuator stops, the servo will turn off and the motor will enter a free-run state.
At this time, the function specified by the applicable parameter (electromagnetic brake) becomes active (provided
that the actuator is equipped with a brake).
When the servo turns off, the deviation counter will be cleared if User Parameter No. 58 (Clear deviation at servo
off/alarm stop) is set to “Enable.”
„ Reset Signal Input (RES)
This signal resets the alarms currently detected by the controller.
You can turn the RES signal ON to reset the alarms currently detected by the controller.
Caution:
This signal cannot reset cold-start level alarms. Identify the cause of each alarm and remove the cause
before restarting the controller.
37
37
 Torque-limit Selection Signal (TL)
This signal limits the motor torque.
While this signal is ON, the actuator thrust (motor torque) is limited to the torque set in User Parameter No. 57
(Torque limit).
4. Operation Using I/O Signals
Caution:
Excessive deviation (standing pulses) may generate while torque is limited (while the TL signal is
ON) (for example, when the actuator receives load and is prevented from moving just like in
push-motion operation).
If the TL signal is turned OFF in this condition, the controller will instantly start controlling the
actuator at the maximum torque and the actuator may move suddenly or run out of control.
This signal can be disabled using User Parameter No. 61 (Torque-limit command input). Disable the TL signal if it is
not used.
 Homing Signal (HOME)
This command signal is used to perform homing automatically.
The homing command is processed at the leading edge (ON edge) of the HOME signal to cause the actuator to
return to its home automatically.
When the homing is completed, the HEND (homing complete) output signal turns ON.
Program the host controller (PLC) so that its current-value register will be reset to the home (“0” will be input to the
register) by the current-value preset function, etc., upon turning ON of the HOME signal.
* This signal is always enabled as long as the servo is on.
* Even after homing has been performed once, homing can be performed again by turning the HOME signal ON.
Caution:
38
38
 The HOME signal is given priority over pulse train commands. Even while the actuator is moving
under a pulse train command, it will start moving to the home once the HOME signal is turned
ON.
 The HOME signal is processed only at its leading edge (ON edge).
 If the SON signal turns OFF or an alarm is detected during homing, the homing operation will
stop. If the servo turns off, the homing command will be cancelled even if the HOME signal is
still ON. To perform homing again, turn the HOME signal OFF, and then turn it back ON.
 The actuator can be operated without using this function. If this function is not used, however, all
management actions over position data will be left to the host controller.
In this case, take necessary measures to prevent an over-stroke error, such as not sending pulse
commands exceeding the effective stroke, or providing external limit switches or other devices for
detecting stroke ends to forcibly stop the actuator upon detection of a stroke end.

Command Pulse Input
Command pulses can be input in the open collector mode (MAX 60 kpps) or differential line driver mode (MAX 200
kpps).
You can select a desired input pattern of command pulses from 90° phase-difference (phase-A/B x4) signal, pulse
train + forward/reverse signal, and forward pulse/reverse pulse. The positive logic or negative logic can be selected
for each of these patterns.
Caution:
●
4. Operation Using I/O Signals
The actuator moves in the negative direction (the motor runs in the forward direction) when
forward pulses are input, and moves in the positive direction (the motor runs in the reverse
direction) when reverse pulses are input. (These directions are reversed if the actuator is of motor
reversing type.)
When determining the forward/reverse directions, pay attention to the host controller setting as
well as the PP•/PP and NP•/NP connection.
For actuator accelerations/decelerations, set values not exceeding the rated
acceleration/deceleration of the actuator. (The rated acceleration/deceleration of each actuator is
specified in the actuator’s catalog.)
* The motor direction is determined based on CCW representing the forward direction when viewed
from the load-end of the shaft.

Positioning Complete Signal (INP)
This signal turns ON when the deviation in the deviation counter (standing pulses) is within the positioning band. It
remains OFF while the servo is off.
Caution:
●
●
●
40
This signal turns ON when the servo is turned on (to perform positioning at the present position).
This signal turns ON simply due to accumulation of deviation (standing pulses). Therefore,
setting an excessively wide positioning band in the applicable position control parameter will
cause the INP signal to turn ON once the actuator enters the positioning band during
low-speed operation (before positioning is completed).
The INP signal is recognized even when the TL signal is ON.
 Homing Complete Signal (HEND)
This signal turns ON after homing has completed and the coordinate system has been established.
It turns ON upon completion of homing initiated by the HOME signal or a command from the teaching pendant or
PC software.
This signal turns OFF once the servo turns off. Perform homing again after the servo has turned off.
Caution:


 Servo-on Output Signal (SV)
When the SON (servo-on) signal turns ON, the servo turns on. As the controller subsequently enters a ready state
(where it can accept pulse train input) (the condition where the controller can accept pulse train input = pulse mode),
this signal turns ON.
This signal turns OFF when the servo is turned off upon turning OFF of the SON signal.
This signal is linked to the LED (green light) on the front panel of the controller.
 Alarm Signal (*ALM)
This signal turns OFF when the controller’s protective circuit (function) has actuated following an alarm detection
and the basic cutoff procedure has been implemented as a result.
The signal will turn ON if the RES (reset) signal is turned ON after the cause of the alarm has been removed
(except when the alarm relates to a cold-start level error).
When an alarm is detected, a red LED light will illuminate on the front panel of the controller. A green LED remains
on while the controller is operating normally.
Caution:
 Identify the cause of each alarm and remove the cause before restarting the controller.
You can check alarm codes using the teaching pendant or PC software. The controller can
store data of up to 16 most recent alarms. This alarm history data will be retained even after
the power is cut off.
Each alarm record is displayed with the time it was generated, so you can check which alarm
occurred when.
 For details on alarm history, refer to 6.3, “Alarms, Causes and Actions.”
41
4. Operation Using I/O Signals
The software stroke limits set by the corresponding actuator parameters are effective only
while this signal is ON.
The actuator can be operated without using this function. In this case, however, take
necessary measures, such as not sending pulse commands exceeding the effective stroke, or
providing external limit switches for detecting stroke ends to forcibly stop the actuator upon
detection of a stroke end.
4.2.2

4. Operation Using I/O Signals
Warning:
Since the drive motor is a pulse motor, the excited phase is detected when the servo is turned on for
the first time after turning on the power.
Therefore, one condition for the servo to turn on is that the actuator can move once the servo is turned
on.
If the slider or rod is contacting a mechanical end or the work is contacting any peripheral equipment,
the excited phase may not be detected correctly and an erroneous movement or excitation detection
error may occur.
In this case, move the actuator manually to an appropriate position before turning the servo on.
If the actuator is equipped with a brake, the brake must be forcibly released by turning on the brake
release switch. At this time, be careful not to pinch your hand or damage the robot hand or work by the
slider/rod, as the slider/rod may drop unexpectedly by its dead weight. If the actuator cannot be moved
by hand, you can change Parameter No. 28 (Direction of excited phase signal detection). Before
changing this parameter, contact IAI.

 Torque-limit Selection Signal (TL)
This signal limits the motor torque.
While this signal is ON, the actuator thrust (motor torque) is limited to the torque set in User Parameter No. 57
(Torque limit).
Caution:
 Do not turn the TL signal OFF while it is ON.
 If the TL signal is turned OFF in this condition, the controller will instantly start controlling the
actuator at the maximum torque and the actuator may move suddenly or run out of control.
4. Operation Using I/O Signals
This signal can be disabled using User Parameter No. 61 (Torque-limit command input). Disable the TL signal if it is
not used.
 Homing Signal (HOME)
This command signal is used to perform homing automatically.
When the HOME signal is turned ON, the command will be processed at the leading edge (ON edge) of the signal
and the actuator will return to its home automatically.
When the homing is completed, the HEND (homing complete) output signal turns ON.
Program the host controller (PLC) so that its current-value register will be reset to the home (“0” will be input to the
register) by the current-value preset function, etc., upon turning ON of the HOME signal.
* This signal is always enabled as long as the servo is on.
* Even after homing has been performed once, homing can be performed again by turning the HOME signal ON.
Caution:
 The HOME signal is given priority over pulse train commands. Even while the actuator is moving
under a pulse train command, it will start moving to the home once the HOME signal is turned
ON.
 The HOME signal is processed only at its leading edge (ON edge).
 If the SON signal turns OFF or an alarm is detected during homing, the homing operation will
stop. If the servo turns OFF , the homing command will be cancelled even if the HOME signal is
still ON. To perform homing again, turn the HOME signal OFF, and then turn it back ON.
 The actuator can be operated without using this function. If this function is not used, however, all
management actions over position data will be left to the host controller.
In this case, take necessary measures to prevent an over-stroke error, such as not sending pulse
commands exceeding the effective stroke, or providing external limit switches or other devices for
detecting stroke ends to forcibly stop the actuator upon detection of a stroke end.

Command Pulse Input
Command pulses can be input in the open collector mode (MAX 60 kpps) or differential line driver mode (MAX 200
kpps).
You can select a desired input pattern of command pulses from 90° phase-difference (phase-A/B x4) signal, pulse
train + forward/reverse signal, and forward pulse/reverse pulse. The positive logic or negative logic can be selected
for each of these patterns.

Caution:
●
The actuator moves in the negative direction (the motor runs in the forward direction) when
forward pulses are input, and moves in the positive direction (the motor runs in the reverse
direction) when reverse pulses are input. (These directions are reversed if the actuator is of motor
reversing type.)
When determining the forward/reverse directions, pay attention to the host controller setting as
well as the PP•/PP and NP•/NP connection.
For actuator accelerations/decelerations, set values not exceeding the rated
acceleration/deceleration of the actuator. (The rated acceleration/deceleration of each actuator is
specified in the actuator’s catalog.)
* The motor direction is determined based on CCW representing the forward direction when viewed
from the load-end of the shaft.

This signal turns OFF when the servo is turned off upon turning OFF of the SON signal.
This signal is linked to the LED (green light) on the front panel of the controller.
Alarm Signal (*ALM)
This signal turns OFF when the controller’s protective circuit (function) has actuated following an alarm detection
and the basic cutoff procedure has been implemented as a result.
The signal will turn ON if the RES (reset) signal is turned ON after the cause of the alarm has been removed
(except when the alarm relates to a cold-start level error).
When an alarm is detected, a red LED light will illuminate on the front panel of the controller. A green LED remains
on while the controller is operating normally.
Caution:

52
The software stroke limits set by the corresponding actuator parameters are effective only
while this signal is ON.
The actuator can be operated without using this function. In this case, however, take
necessary measures, such as not sending pulse commands exceeding the effective stroke, or
providing external limit switches for detecting stroke ends to forcibly stop the actuator upon
detection of a stroke end.
Identify the cause of each alarm and remove the cause before restarting the controller.
You can check alarm codes using the teaching pendant or PC software. The controller can
store data of up to 16 most recent alarms. This alarm history data will be retained even after
the power is cut off.
Each alarm record is displayed with the time it was generated, so you can check which alarm
occurred when.
For details on alarm history, refer to 6.3, “Alarms, Causes and Actions.”

Warning:
56
Since the drive motor is a pulse motor, the excited phase is detected when the servo is turned on for the
first time after turning on the power.
Therefore, one condition for the servo to turn on is that the actuator can move once the servo is turned
on.
If the slider or rod is contacting a mechanical end or the work is contacting any peripheral equipment, the
excited phase may not be detected correctly and an erroneous movement or excitation detection error
may occur.
In this case, move the actuator manually to an appropriate position before turning the servo on.
If the actuator is equipped with a brake, the brake must be forcibly released by turning on the brake
release switch. At this time, be careful not to pinch your hand or damage the robot hand or work by the
slider/rod, as the slider/rod may drop unexpectedly by its dead weight. If the actuator cannot be moved
by hand, you can change Parameter No. 28 (Direction of excited phase signal detection). Before
changing this parameter, contact IAI.

Detail Explanation of Parameters
If you have changed any parameter, be sure to restart the controller via a software reset or reconnect the controller
power.
5.2.1
Parameters Relating to Actuator Stroke Range
z Soft Limits (No.3 LIMM) (No.4 LIML)
5. Parameter Settings
Set the + soft limit in parameter No. 3 and – soft limit in parameter No. 4.
Both parameters have been set to the effective actuator length at the factory. Change the parameter settings if
necessary, such as when an obstacle is present and collision between the actuator and obstacle must be prevented or
when the actuator must be operated beyond the effective length.
Exercise due caution when setting these parameters, as wrong settings will cause collision with the mechanical end.
The minimum setting unit is 0.01 mm.
(Note) To change these parameters, set values corresponding to positions that are 0.3 mm wider than the desired
effective range.
Example) Set the effective range to between 0 and 80 mm

z Home Direction (No.5 ORG)
If not specified by the user, the home direction is set to the motor side before shipment.
If you must change the home direction after the actuator has been assembled to your equipment, change the setting of
parameter No. 5.
Also change the parameters for home offset, soft limits and default direction of excited phase signal detection, if
necessary.
Caution:
64
64
Rod-type actuators do not permit reversing of the home direction.
Note that if the home direction is reversed, all the entered position data will be cleared.
z Home Offset (No.22 OFST)
Parameter No. 22 has been set to an optimal value at the factory so that the distance from the mechanical end to home
will remain constant.
The minimum setting unit is 0.01 mm.
This parameter can be adjusted in the following conditions:
[1] Align the actuator’s home with the mechanical home on the equipment after the actuator has been assembled to
the equipment.
[2] Set the home position again after reversing the factory-set home direction.
[3] Correct the minor position deviation that has generated after the actuator was replaced.
Caution:
If you have changed the home offset, the soft limit parameters must also be reviewed.
5. Parameter Settings
65
65
5.2.2
Parameters Relating to Actuator Operating Characteristics
Default Acceleration/Deceleration (No.9 ACMD)
The factory setting is the rated acceleration/deceleration of the actuator.
This value will be the acceleration/deceleration value during jog operation from the teaching pendant or PC software.
To decrease the default acceleration/deceleration from the rated acceleration/deceleration, change the value set in
Parameter No. 9.
Default Positioning Band (In-position) (No.10 INP)
5. Parameter Settings
Factory setting for parameter No. 10 is 0.01 mm.
This value is used for evaluating positioning completion. With a pulse-train input type, the positioning complete signal
(INP) turns ON when the deviation in the deviation counter (standing pulses) is within the range indicated by this
parameter.
Increasing this value may cause output of positioning complete signal (INP) even though the actuator is still moving.
Caution:
For the positioning band, set the value greater than that of the encoder resolution.
Setting it smaller may cause a servo error.
Current-limiting Value during Homing (No.13 ODPW)
Before shipment, this parameter is set to a current level appropriate for the standard specification of the actuator.
Increasing this parameter value increases the homing torque.
This parameter need not be changed in normal conditions of use. However, if the actuator is used in vertical orientation
and the slide resistance increases due to the affixing method, load condition, etc., homing may complete before the
correct position. In this case, the value set in Parameter No. 13 must be increased. (As a guide, the setting should not
exceed 75%.)
Current-limiting Value at Standstill after Positioning (No.12 SPOW)
Before shipment, this parameter is set to a current level appropriate for the standard specification of the actuator.
Increasing this parameter value increases the holding torque.
This parameter need not be changed in normal conditions of use. If the actuator receives large external force while
standing still, however, hunting will occur. In this case, the value set in Parameter No. 12 must be increased. (As a
guide, the setting should not exceed 50%.)
66
66
z Default Direction of Excited Phase Signal Detection (No.28 PHSP)
The excited phase is detected when the servo is turned on for the first time after turning on the power. This parameter
defines the direction of this detection.
This parameter need not be changed in normal conditions of use. However, if the actuator is contacting a mechanical
end or any obstacle when the power is turned on and cannot be moved by hand, change the direction of detection to
one in which the motor can be driven easily.
To do this, set the value of Parameter No. 28 to either “0” or “1.” If the direction of detection is to be the same as the
home direction, specify the same value currently set in Parameter No. 5, “Home direction.”
To set the direction opposite to the home direction, specify the value different from the one currently set in Parameter
No. 5, “Home direction.”
(Example 1) The power is turned on when the slider is contacting the bottom mechanical end in a configuration where
the motor is positioned at the top.

z Excited Phase Signal Detection Time (No.29 PHSP)
The excited phase is detected when the servo is turned on for the first time after turning on the power. This parameter
defines the time of this detection.
Before shipment, this parameter is set to a detection time appropriate for the standard specification of the actuator, and
thus the setting need not be changed in normal conditions of use.
Should an excitation detection error or abnormal operation occur when the servo is turned on for the first time after
turning on the power, you can try changing the detection time set in Parameter No. 29 as a possible countermeasure.
Before changing this parameter, contact IAI.
z Safety Speed (No.35 SAFV)
This parameter defines the feed speed during jog operation from the teaching pendant or PC software.
The factory setting is “100” [mm/sec].
To change the speed, set an optimal value in Parameter No. 35.
Since the maximum speed is limited to 250 mm/sec, set the safety speed to below this level.
* This parameter is invalid during pulse train control.
67
67
z Default Standstill Mode (No.53 HSTP)
This parameter defines the power-saving mode to be applied when the standby time while the servo is on is long after
power on.
In Parameter No. 53, define whether or not to implement power-saving.
All power-saving modes are disabled
Full servo control mode
The factory setting is “0” [Disable].
Setting
0
4

5. Parameter Settings
The pulse motor is servo-controlled to reduce the holding current.
Although the specific level of current reduction varies in accordance with the actuator model, load condition, etc.,
generally the holding current drops to around a half to one-fourth.
The servo remains on, so position deviation does not occur.
The actual holding current can be checked in the current monitor screen of the PC software.

Setting unit: %
Upper limit of the setting range will be 70% of the rated value.
z Monitor Error White Limitation Torque (No.59 FSTP)

internal parameter setting during torque limiting (while TL signal is ON).
Setting

If this parameter is set, it sets the communication speed to be used when the controller implements serial
communication control via the PLC’s communication module.
Set Parameter No. 16 to a value appropriate for the specification of the communication module.
9600, 19200, 38400 or 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 is not used with this controller. It applies to controllers of serial communication type.
If this parameter is set, it defines the minimum delay before the controller’s transmitter is activated following the
completion of command reception, when the controller implements serial communication control via the PLC’s
communication module.
The factory setting is “5” msec. If the communication module specification exceeds 5 msec, set the required time in
Parameter No. 17.
z Silent Interval Multiplication Factor (No.45 SIVM)
This parameter is not used with this controller. It applies to RS485 serial communication commands.
If this parameter is set, it defines the multiplication factor of silent interval time to be used for delimiter judgment in the
RTU mode.
The factory setting is the communication time corresponding to 3.5 characters in accordance with the Modbus
specification.
This parameter need not be changed in normal conditions of use where the actuator is operated using a PC or teaching
pendant.
If the character sending interval exceeds the silent interval because the scan time of the PLC is not ideal, however, you
can extend the silent interval time through Parameter No. 45.
The minimum setting unit is 1 (times), and the input range is 0 to 10. If “0” is set, it means that the silent interval
multiplication factor is disabled.

Servo Gain Adjustment
Since the servo has been adjusted at the factory in accordance with the standard specification of the actuator, the
servo gain need not be changed in normal conditions of use.
However, vibration or noise may occur depending on how the actuator is affixed, specific load condition, and so on, and
therefore the parameters relating to servo adjustment are disclosed to allow the customer to take quick actions should
adjustment become necessary.
Particularly with custom models (whose ball screw lead or stroke is longer than the that of the standard model),
vibration/noise may occur due to external conditions.
In this case, the parameters shown below must be changed. Contact IAI for details.

Troubleshooting
What to Do When A Problem Occurs
If you encountered a problem, follow the steps below to conduct the specified checks to gather information needed to
implement quick recovery and prevent recurrence of the problem.
6. Troubleshooting
a. Check the status indicator lamps
SV (green) --- The servo is on.
ALM (red) --- An alarm is present or emergency stop has been actuated, or the motor drive power is cut off.
b. Check the host controller for abnormality.
c. Check the voltage of the 24-VDC main power supply.
d. Check the voltage of the 24-VDC power supply for I/O signals.
e. Check for alarms.
Check the details of each alarm on the PC or teaching pendant.
f. Check the cables for miswiring, disconnection and pinching.
Before checking the continuity of cables, turn off the power (to prevent a runaway actuator) and disconnect all
wirings (to prevent the power from being supplied unexpectedly due to a sneak path).
g. Check the I/O signals.
h. Check the noise elimination measure (ground connection, surge killer installation, etc.).
i. Identify how the problem occurred and the operating condition when the problem occurred.
j. Check the serial numbers of the controller and actuator.
k. Analyze the cause.
l. Take an action.
Before contacting IAI, please check the items in a through j above. Provide the information to our technical staff.

After the start of homing, homing does not complete after elapse of the
time set by the manufacturer’ s parameter. (This alarm does not
generate during normal operation.)
As one possible cause, the controller and actuator combination may be
incorrect. Contact IAI.
The motor speed exceeds the maximum speed set by the
manufacturer’ s parameter.
This alarm does not generate during normal operation, but it may occur
if the load decreased before a servo error was detected and the motor
speed has increased as a result. This condition occurs due to the
following reasons:
[1] The slide resistance of the actuator is large in some areas.
[2] The load increased due to momentary application of external force.
Check the assembly condition of mechanical parts for any abnormality.
If the actuator itself is suspected as the cause, contact IAI.
This alarm indicates that after the acceptance of the move command, the motor
could not operate for 2 seconds or more before the actuator reached the target
position.
Cause: [1] The connector of the motor relay cable is loose or its circuit is 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 sliding resistance of the actuator itself is high.
[5] The positioning band setting is smaller than the encoder resolution.
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 check if “click” sound is heard.
[3] Check the assembly condition of mechanical parts for any
abnormality.
[4] If the load is normal, cut off the power and move the actuator by
hand to check the slide resistance.
If the actuator itself is suspected as the cause, contact IAI.

Common Problems and Recommended Actions
z I/O Signals Cannot Be Sent or Received to/from the PLC.
Cause:
Action:
6. Troubleshooting
Caution:
[1] The 24-V I/O power supply is connected in reverse polarities.
(In this case, input circuits are not affected, but output circuits will be damaged.)
[2] If an output circuit presents this problem, electrical current exceeding the maximum current flowed
due to a large load and a circuit component was damaged.
[3] Poor contact at the connector or relay terminal block on the PLC side.
[4] The female pins on the flat cable connector are bent outward, thus causing contact failure with the
male pins on the controller connector.
Check the connection condition of the power supply and connector, as well as the load on the output
side.
If [1] or [2] is suspected, the controller must be replaced. If [4] is likely, the flat cable must be replaced.
Either way, contact IAI.
When checking the continuity of the shield cable, exercise due caution not to bend the female pins
on the connector outward. It may cause contact failure, resulting in malfunction.
z The ALM Lamp Illuminates after the Power Is Turned On.
(An alarm is present, emergency stop is actuated, or the motor power is 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 remove the cause.
* If the ALM output signal is ON, the emergency stop circuit is actuated.
Check the following items:
[1] Is the emergency stop switch on the operation panel pressed by mistake? Is the necessary interlock canceled?
[2] Is the emergency stop switch on the teaching pendant pressed by mistake?
[3] Is Parameter No. 42 (Enable Function) set to enabled by mistake after connecting a teaching pendant that does
not support the enable switch?
[4] If multiple controllers are linked together, are they wired correctly?
z After Turning On the Power, the SV Lamp Does Not Illuminate upon Servo-on Signal Input.
(The Servo Does Not Turn On.)
Cause:
[1] I/O shield cable contact failure
[2] Faulty controller
Check the servo-on signal (SON) in the I/O monitor screen on the PC or teaching pendant.
If the signal is input, the controller may be faulty. Contact IAI.

z The Actuator does not Operate when a Pulse Train is Input.
Cause:
Action:
Caution:
[1]
[2]
[1]
[2]
The I/O I/F signal issued with the pulse train is invalid.
The command-pulse train pattern is not set properly in the parameters.
Check the input signal.
Check User Parameter No. 63 (Command-pulse input mode) and No. 64 (Polarity in command-pulse
input mode).
With certain third-party host controllers, the positive and negative logic settings of pulse train
patterns are opposite to those of IAI’s controllers. Reverse the positive and negative logic settings
to see if the problem is resolved.
z With an Actuator Installed in Vertical Orientation, Noise Generates during Downward Movement.
6. Troubleshooting
Cause:
Action:
The load exceeds the rated load capacity.
[1] Decrease the speed.
[2] Decrease the value set in User Parameter No. 7 (Servo gain number). As a guide, do not decrease
the setting to below 3.
z Vibration Occurs when the Actuator Is at Standstill.
Cause:
Action:
The slider is receiving external force.
If external force cannot be removed, increase the value set in User Parameter No. 12 (Current-limiting
value at standstill after positioning).
Increasing the setting of this parameter increases the holding torque. As a guide, keep the current
limiting value to 70% or below.
z Stopped Position Sometime Deviates from the Home Position or Target Position.
Cause:
Action:
[1] Encoder waveforms are disturbed due to noise.
[2] If the actuator is of rod type, non-rotational error increased due to application of rotational moment to
the rod.
[1] Check if the grounding is provided correctly, and also check for any equipment that may be
generating noise.
[2] Depending on the condition, the actuator may have to be replaced. Contact IAI.
z The Actuator Moves Only a Half, or as Much as Twice, the Specified Travel.

Cause:
[1] The controller and actuator combination is incorrect.
[2] The ball screw lead varies according to the actuator type. If the actuator is not combined with an
appropriate controller, the travel and speed will change.
[3] Wrong electronic gear setting
[4] Pre-shipment setting error at IAI
Action:
[1] If multiple actuators of different types are used, check the label on each actuator or use other means
to see if they are connected to correct controllers.
[2] Recalculate for electronic gear.
[3] Contact IAI.
z A Servo Error Occurred while the ROBO Gripper Was Moving.
Cause:
Action:
The work was not positioned properly and a finger attachment contacted the work in the positioning
mode.
Consider how much the work deviates and adjust the start position of push-motion operation, as well as
the thickness of the finger attachment (including buffer material), so that the work can be clamped
properly in the push-motion mode.
Before resetting the error, be sure to turn the open/close screw and loosen the finger attachments first,
because the feed mechanism may be locked.
Caution:
If the alarm is reset when the servo-on signal is disabled or while the servo-on signal is ON, the servo will
turn on.
Turning the open/close screw in this condition only results in the screw returning to the original position, and
the feed mechanism remains locked. Therefore, the alarm will generate again the next time a move
command is issued.
6. Troubleshooting
[Two-finger type]
OPEN
Open/close screw
Turn counterclockwise using a flat-head screwdriver.
[Three-finger type]
Remove one of the finger attachments and take out the work, and then turn the open/close screw clockwise.
Remove one of the finger attachments.
Open/close
screw
Turn clockwise.

z The Actuator Malfunctions when the Servo Is Turned On after Turning On the Power.
Cause:
6. Troubleshooting
Action:
86
86
Excited phase detection is not performed properly when the servo is turned on, because one of the
following conditions exists when the power was turned on:
[1] The slider or rod was contacting a mechanical end.
[2] The work was pushed by a strong external force.
[1] Check if the slider or rod is not contacting a mechanical end. If the slider/rod is contacting a
mechanical end, separate the slider/rod from the mechanical end.
If it is equipped with a brake, turn the power ON to force release the brake before moving.
At this time, be careful not to pinch your hand or damage the robot hand or work by the slider/rod, as
the slider/rod may drop unexpectedly by its dead weight.
If the actuator cannot be moved by hand, one measure is to check the direction of excited phase
signal detection and change the direction of detection as necessary. If you wish to change the
direction, contact IAI beforehand.
For details, refer to the applicable parameter explained in 6.2.2, “Parameters Relating to Actuator
Operating Characteristics.”
[2] Check if the work is not contacting any peripheral equipment.
If the work is contacting peripheral equipment, separate the work from the equipment by providing a
minimum clearance of 1 mm in between.
If neither [1] nor [2] applies, contact IAI.

The push force is based on the rated push speed (factory setting) indicated in the list, and provides
only a guideline.
Make sure the actual push force is equal to or greater than the minimum push force. If not, the push
force will not stabilize.
Do not change the setting of push speed (parameter No. 34). If you must change the push speed,
consult IAI.
If, among the operating conditions, the positioning speed is set to a value equal to or smaller than
the push speed, the push speed will become the set speed and the specified push force will not
generate.

Appendix
Push Force and Current-limiting Value
Caution




The relationship of push force and current-limiting value is based on the rated push speed (factory setting) and
provides only a guideline.
Make sure the actual push force is equal to or greater than the minimum push force. If not, the push force will not
stabilize.
Do not change the setting of push speed (parameter No. 7). If you must change the push speed, consult IAI.
If, among the operating conditions, the positioning speed is set to a value equal to or smaller than the push speed,
the push speed will become the set speed and the specified push force will not generate.
