1 Conveyor Synchronized Function

1.2

Conveyor Synchronized Operation

The position tracking type conveyor synchronized operation function modifies the taught path in conveyor non-moving state according to the conveyor moving amount so that the manipulator performs follow-up motion in the conveyor moving direction with constant speed relative to the workpiece.

For example, teach P1 to P7 (P2 to P6 are the points in synchronization) with the conveyor stopped. In playback operation, the manipulator follows the conveyor (workpiece) with the motion path modified in

the conveyor moving direction as shown in the Fig. 1-3 “Synchronized Motion Path in Playback Mode” .

The conveyor synchronized function can use either the manipulator base axis or the traveling axis

(external axis) to follow the movement of conveyor. However, the base axis and the traveling axis can not be selected simultaneously.

1 Conveyor Synchronized Function

1.2.1

Conveyor Home-position Limit Switch

The conveyor home-position limit switch turns ON the conveyor home-position input signal when a workpiece is detected by a sensor.

1.2.2

Conveyor Home-position Input Signal

When the conveyor home-position input signal is input, the conveyor current value is automatically reset to 0 mm.

Then, the manipulator can enter synchronized operation status by execution of SYSTART instruction.

Conveyor home-position limit switch

Conveyor moving direction

0 mm

1.2.3

SYSTART Instruction and Manipulator Motion

The SYSTART is a conveyor synchronized operation start instruction.

Format: SYSTART CV#(1) <STP= Synchronization start position (units: mm)>

After having executed the SYSTART instruction, when the conveyor reaches the position specified at

STP as the synchronization start position, the manipulator enters the synchronized operation status.

Up to this moment, the manipulator does not move.

When a workpiece reaches the position set as the synchronization start position, the manipulator starts the synchronized operation.

1 Conveyor Synchronized Function

If the SYSTART instruction is executed before the input of conveyor home-position input signal, the manipulator waits until the conveyor home-position input signal is input and the conveyor reaches the synchronization start position, then starts the synchronized operation.

If the conveyor home-position input signal is input before the execution of SYSTART instruction, the manipulator waits until the conveyor reaches the synchronization start position, then enters in synchronized operation status.

1.3.2

Definition of Conveyor Moving Direction

The conveyor moving amount pulses detected by the encoder mounted on the conveyor are scalar.

From this number of pulses, the manipulator determines how far to move, but not in which direction.

Therefore, the conveyor moving direction must be defined for the manipulator. For the definition of moving direction, a user coordinate is used. (Refer to “



TRACKING (ROBOT-AXIS/BASE-AXIS/

CIRCULAR)".)

For registration of user coordinates, refer to “NX100 INSTRUCTIONS”.

1.3.3

Conveyor Distance for Follow-up

With the conveyor synchronized function of NX100, a manipulator can synchronize a conveyor continuously over a maximum distance of 21 m within the manipulator working envelop.

Since the distance more than 21 m can not be processed internally, if the moving distance reaches 21 m during synchronized operation, the alarm 5022 “CONVEYOR POSITION LIMIT” occurs and the manipulator stops disregarding the succeeding synchronization.

1.3.4

Measurement of Conveyor Moving Amount

How far the conveyor has moved from the conveyor home-position is measured by the cumulative number of feedback pulses from the encoder mounted on the conveyor. The accumulation starts when the conveyor home-position limit switch is turned ON. At the start, the cumulative amount is zero (0).

Connecting Conveyor Home-Position Signals

to NX100

174074-1CD

The conveyor home-position input signals are connected through each encoder input port on the

JANCD-NSL01 board. Since the conveyor home-position input signals are used for the reference to the conveyor position, they must be as in phase as possible. It is recommended to connect the conveyor home position signal from the conveyor home-position limit switch directly to the NX100 so as to eliminate dispersion caused by sequencer scan time errors. Input the conveyor home-position limit switch signals to the corresponding conveyor port channels as shown in the figure below so that each signal will not be received while the corresponding channel is executing synchronization.

Check whether the conveyor home-position input signals function correctly on the conveyor condition file window explained later.

AVERAGED TRAVEL TIME (0 to 3000 ms)

At sudden change in the conveyor moving amount, the moving amounts is automatically averaged so that the manipulator moves smoothly. However, the synchronization responsiveness is lowered in this case. When the conveyor motion is not smooth, set the value to approx. “200”. When this function is not used, set at “0”.

RESET SIGNAL MONITORING (0 to 65535 ms)

Set a time to wait for the conveyor home-position input signal when no encoder reset signal for a specified conveyor has been input at the execution of SYSTART instruction.

When the waiting time exceeds the set value, the SYSTART instruction is aborted and the next instruction is executed. Therefore, prepare the job so that the manipulator takes retreat motion by internal status. When “0” is set, the system waits for the conveyor homeposition input signal without being interrupted by the time limit for encoder reset signal monitoring.

CONVEYOR SPEED DOWN MODE (EXECUTE/ALARM/PAUSE JOB)

Specify the manipulator motion when the conveyor speed is reduced lower than the conveyor lower speed limit specified in 16 .

This mode is used where a conveyor stop detection mechanism does not exist in the conveyor control board.

When the conveyor speed is lowered below the conveyor lower limit speed, an alarm occurs and the manipulator stops.

PAUSE JOB: When the conveyor speed is so lowered that it becomes below the set value in “CONVEYOR LOWER LIMIT SPD” of the conveyor condition file continuously for 0.1 second, the job motion is interrupted and the manipulator performs only the follow-up motion in the conveyor moving direction.

Then, when the conveyor speed is recovered to the set value in CONVEYOR

When the conveyor speed is lowered below the conveyor lower limit speed, the execution of move instruction in the job is interrupted and the manipulator performs only the follow-up motion in the conveyor moving direction.

When the conveyor speed is recovered and become higher than the conveyor lower limit speed, the execution of job restarts.

Setting Conveyor Positional Resolution

The encoder mounted on the conveyor sends a pulse amount as the conveyor current position. In order that the manipulator recognizes this pulse amount as the conveyor moving amount for its synchronized motion, the pulse amount must be converted into a distance.

The conveyor moving amount (

μ m) per 1 pulse to be used for this conversion is called “POSITIONAL

RESOLUTION”.

Encoder

NX100

Pulse amount

(in units of pulse)

Distance

(in units of mm)

Converted by the conveyor positional resolution

POSITIONAL RESOLUTION 240.00 /p

Conveyor Condition File Window

The conveyor positional resolution is set in units of μ . For example, when the positional resolution is 30

μ /pulse, set “30.00” in POSITIONAL RESOLUTION”.

The setting range is from 0 to 999.99 μ . Since the NX100 internally quadruples every encoder pulse number, the actual conveyor positional resolution for the conveyor encoder is up to 3999.96 μ /pulse.

As the resolution error accumulates for the conveyor moving pulse amount, the setting must be made correctly. For example, setting the resolution 0.01 μ /pulse bigger causes the follow-up error of 0.1 mm at the point that the conveyor moves for 10000 pulses.

The conveyor resolution is mentioned in the specification of each conveyor, however, the value cannot be used as it is for the reasons explained below. Measure the actual conveyor resolution in the following manner.

NOTE

The NX100 internally quadruples the feedback pulse from the conveyor encoder.

Accordingly, the conveyor positional resolution set in the conveyor condition file is 1/4 of the conveyor resolution mentioned on your conveyor specification.

SYSTART Instruction



Function

This instruction indicates the start of a conveyor synchronized operation sequence. The manipulator starts follow-up motion by a move instruction after the SYSTART instruction, or TIMER or WAIT instruction.

When this instruction is executed, the manipulator stops and waits until the conveyor current position value exceeds the synchronization start position value. When it exceeds, the manipulator starts the synchronized motion.

After the instruction is executed, if the encoder reset signal is OFF and remains OFF for the time specified for “Reset signal monitoring” in the conveyor condition file, the execution of instruction is skipped and the succeeding instructions are executed. In this case, no synchronization takes place.

When the SYSTART instruction is executed, if the conveyor current position value already exceeds the synchronization start position value and the difference is within the tolerance (OL), the manipulator starts immediately from the current position the synchronized motion.

However, when the SYSTART instruction is executed, if the conveyor current position value already exceeds the synchronization start position value and the difference is greater than the tolerance (OL), execute the succeeding instructions without synchronized operation resetting the system variable

Instruction



Function

These move instructions perform the conveyor synchronized motion. Except that the conveyor position at the time of teaching is registered as CTP (conveyor teaching position), these instructions are the same as ordinary move instructions. Joint motion, linear interpolation, and circular interpolation can be performed in the same way as the ordinary move instructions. However, SYMOVJ (joint motion for conveyor synchronized operation) can be used only when the base axis is selected for synchronization.

If SYMOVJ is executed when the robot axis is used for synchronization, the alarm 4583 “CAN NOT

USE SMOVJ DURING TRACKING” occurs and the manipulator stops.

Operation

5 Teaching

The interpolation mode of move instructions for conveyor synchronized operation differs from that of ordinary move instructions. Therefore, teaching is performed in “interpolation mode for conveyor synchronized operation”. Switch the interpolation mode in the following manner.

Since the conveyor positions at teaching is registered, they must be properly set up in relation to the conveyor home-position (the position where the conveyor home-position limit switch is ON).

Motion Speed

Generally, teaching in the direction opposite to the conveyor moving direction gives such a result as a manipulator can move more easily and slowly in playback operation.

In the conveyor synchronized operation, the manipulator motion speed is the teaching speed added the conveyor motion speed.

However, depending on the relation between the direction of manipulator motion and the conveyor moving direction, the speed is added in the different way as shown below.

Wrist Posture in Synchronization

In the synchronization section, the wrist maintains its taught posture while the manipulator is synchronizing the conveyor. Teach a posture so that the wrist can be moved in the conveyor moving direction.

R-axis

T-axis

T-axis

Fig. 5-11: Wrist Posture Not Recommended

Fig. 5-12: Wrist Posture Recommended

For example, if the wrist is taught the posture as shown in Fig. 5-11:, the structure of the manipulator

prevents T-axis control in the conveyor moving direction. Trying to compensate this, R-axis turns sharply, possibly leading to an alarm such as segment over during the synchronized operation, which stops the manipulator.

On the contrary, if the wrist is postured as shown in Fig. 5-12: in teaching, T-axis can turn to adapt to

position changes in the conveyor moving direction. In this case, sufficient clearance must be provided around the wrist to allow T-axis to turn for position control.

To check whether the wrist posture is appropriate, move the user coordinate X-axis in the conveyor moving direction with the wrist held in the taught posture to confirm that any axis does not move sharply.

With a move instruction for conveyor synchronized operation, when teaching is performed so that the posture changes largely in short distance, a segment over alarm may occur. To avoid such an alarm, take the following method.

• Set the speed not as “V =



(Tool center point speed)” but as “VR =



(Posture angle speed)

• Lower the speed of “V =

”

Circular Interpolation Steps

Continuous circular interpolation steps should be performed on the same conveyor position.

When continuous circular interpolation steps are taught on different conveyor positions, a path different from the taught path may be resulted in the synchronized operation.

5.5

Teaching

Since the conveyor positions at teaching are registered in a job, they must be properly set up in relation to the conveyor home-position (the position where the conveyor home-position limit switch is ON).

When teaching with a workpiece, move the conveyor and turn ON the conveyor home-position limit switch by the workpiece, then move to a teaching position. When the conveyor home-position limit switch is turned ON, the position where the switch is turned ON is registered automatically as the conveyor home-position.

Notes on Operation

The conveyor synchronized move instructions are special instructions for registering a conveyor position together with a manipulator position. Therefore, different from ordinary move instructions such as MOVJ, these instructions have the following restrictions on operations.

5.7.1

Confirming Reach to Step

When the manipulator reaches the target step in FWD/BWD operation or test run (step motion mode) by a conveyor synchronized move instruction, the operation is stopped and the cursor stops blinking.

In this way, it can be easily confirmed that the manipulator reaches the target step.

NOTE

When the manipulator reaches the target step, the cursor stops blinking, however, the cursor restarts blinking when the following operations are performed. In this case, move the cursor to the target step and perform FWD operation again.

• Emergency stop

• The cursor is moved in editing job

• File and job editing operation

• Jog operation

5.7.2

Backward (BWD) Operation

Releasing [FWD] and pressing [BWD] in middle of FWD operation does not return the manipulator to the previous step, but the manipulator continues the FWD operation to the next step. Pressing [BWD] after the manipulator reaches the next step, returns the manipulator to the previous step.

5.7.3

Changing Tool

The FWD operation of the first SYMOV  instruction after changing a tool, should be performed on the conveyor position at changing a tool.

Performing the FWD operation after changing a tool and moving the conveyor causes a segment over alarm.

5.7.4

Deleting Taught Points

Before deleting a move instruction, the manipulator must be placed at the step position to be deleted.

However, this condition can not be satisfied with conveyor synchronized move instructions. This is because a taught position for a conveyor synchronized move instruction is interpreted to different step positions on the conveyor position, as explained before. Therefore, ordinary deleting operation is not possible.

To delete a conveyor synchronized move instruction, press [MODIFY] to change the step position.

Then, after the cursor blinks, press [DELETE].

Conveyor Speed Down

When the conveyor slows down while the manipulator is synchronizing the conveyor, the manipulator will react according to the mode setting in the conveyor condition data file:

CONVEYOR SPEED DOWN MODE

CONVEYOR LOWER LIMIT SPD

: EXECUTE

: 0 mm/sec

Conveyor Condition File Window

• EXECUTE

Regardless of the conveyor speed, the manipulator continues its operation.

• ALARM

An alarm occurs when the conveyor speed slows down.

• PAUSE JOB

The manipulator stops the job operation but only continues follow-up motion when the conveyor speed slows down.

For details of these three modes, refer to “ 15

CONVEYOR SPEED DOWN MODE (EXECUTE/

ALARM/PAUSE JOB)" explained in

section 4.1 “Conveyor Condition File” .

6.2

Accuracy

The conveyor synchronized operation function reproduces the path taught with the conveyor in stop status.

Therefore, the accuracy of conveyor synchronized operation function is determined by the amount of difference between the taught path and the synchronized path. Since the object is moving, it is impossible to appreciate the accuracy in the same way as the repetitive positioning accuracy for the still-object.

The amount of difference between the taught path and the synchronized path is resulted from the following factors in interaction. Even if the following factors are adjusted not to cause the difference, the difference shows about ten times the difference from repetitive positioning for still-object.

• Linearity of the conveyor in the synchronization section.

• Conveyor movements that are not indicated in motion pulse data from a conveyor encoder (such as swings with a hanger conveyor).

• Differences between the manipulator actual dimensions and the dimensions registered in

NX100.

• Conversion resolution error that occurs when converting the conveyor motion pulse

(number of pulses) from the conveyor encoder to the conveyor moving amount (mm).

The details of conversion resolution error will be explained in section 6.3 “Conveyor

Resolution Error” .

• Manipulator mechanical accuracy such as arm bending.

• Follow-up delay for the conveyor speed fluctuation.

• Manipulator system lag time.

• Difference between the conveyor moving direction and the traveling axis moving direction when the synchronization is performed by the traveling axis.

6.3

Conveyor Resolution Error

The synchronization error resulted from the conveyor resolution setting error increases as the conveyor position value increases. The farther the conveyor moves, the bigger the synchronization error becomes. The minimum value for conveyor positional resolution setting is 0.01

μ m. Therefore, a maximum error of 0.005

μ m per pulse may occur.

For example, when the conveyor resolution is 10 μ m and the synchronization distance is 2 m, 200000 pulses are output while the conveyor moves for 2 m. Since the maximum error per pulse is 0.005

μ m, the synchronization error would be: 200000 pulses ∗ 0.005

μ m = 1 mm.

Restarting Synchronization After Manipulator

Stops

6 Playback

When a manipulator stops during the conveyor synchronized operation in the following cases, the synchronized operation is restarted by restarting the manipulator:

• Minor failure alarm (excluding occurrence of alarm related to the conveyor synchronized function)

• Emergency stop or external emergency stop

• Hold or external hold

• Switch of the mode (mode switching between play and teach mode)

• Switch of the operation cycle (switching among auto/ 1 cycle/ step)

6.5

Continuance of Conveyor Synchronized Status

The conveyor synchronized status started by execution of SYSTART instruction remains until SYEND instruction is executed or the control power supply is turned OFF. Even if a manipulator stops in the cases explained in the previous section, the conveyor synchronized status remains.

Note that conveyor synchronized status is cancelled when a job is executed after the cursor is moved in teach mode, the master job is called or a job selection is made.

6.6

Continuance of Parallel Shift Status

The parallel shift status in the conveyor synchronized status continues even after a manipulator stops in the cases explained in the previous section. However, the parallel shift status is cleared in the following cases. Be careful when using the parallel shift function in combination with the conveyor synchronized function.

• Execution of SFTOF instruction

• The cursor is moved in teach mode

• The master job is called

• Job selection

• The main power supply is shut down.

6.7

Conveyor Synchronized Operation During

Execution of TIMER and WAIT

While the manipulator is in waiting status by execution of TIMER, WAIT, and so forth, the conveyor synchronized operation continues.

Virtual Encoder Mode

8.1

Virtual Encoder Pulse Count

When the manipulator is stopped during operation with a virtual encoder, the virtual encoder pulse counting is stopped as well as the manipulator. Since the virtual encoder continues counting pulses by restarting the manipulator, the manipulator can be restarted from the position where it stopped.

8.2

Relation Between Encoder Input and Virtual

Encoder Input

There are two types of settings for encoder input:

• Setting by “ENCODER INPUT” in the conveyor condition file.

• Setting by “VIRTUAL ENCODER INPUT” in the conveyor condition file.

The relation between “ENCODER INPUT” setting and the virtual encoder by “general purpose input signal” setting is as follows:

• When the “ENCODER INPUT” = “VIRTUAL ENCDR”

Regardless of the status of general purpose input signal, the manipulator operates with the virtual encoder pulse.

• When the “ENCODER INPUT” = “ENCODER”

When the general input signal is ON, the manipulator operates with the virtual encoder pulse.

When the general input signal is OFF, the manipulator operates with the encoder input.

8.3

Precaution on Switching the Encoder Mode

Switching the mode “Encoder/Virtual Encoder” by the general purpose input signal during the conveyor synchronized operation causes the alarm “CANNOT CHANGE CONVEYOR MODE”.

Be sure to switch the encoder mode by the general purpose input signal while the manipulator is not in the conveyor synchronized operation.

Manual Conveyor Function

Manual Conveyor Function is a manual setting function for conveyor position. This function enables the conveyor position to be set from the programming pendant without moving the conveyor to modify the taught job.

With this function, instead of moving the conveyor to move the workpiece to the teaching position, by removing a fastening device such as a dog and moving the workpiece to the desired position on the conveyor, the conveyor position can be input to modify the taught job. When the taught job is modified by using the Manual Conveyor Function, the newly set value of the conveyor position is registered to the value of CTP when the registration of the move instruction for the synchronized motion (SYMOV  ) is modified.
