4.2 Troubleshooting Motion Errors

Troubleshooting Motion Errors

4-10

Bit 6: Positive Overtravel and Bit 7: Negative Overtravel

Bit 8: Servo ON Incomplete

Bit 9: SERVOPACK Communications Warning

Note: If communications errors occur consecutively, an alarm will be shown in IL04 bit 11 (SERVOPACK Com-

munications Error).

Bit A: SERVOPACK Stop Signal Active

Detection Timing

During execution of a movement motion command. Overtravel detection is enabled
while the OT signal in travel direction is OFF.

Processing When
Warning Occurs

• Stop processing is performed in the SERVOPACK.

The stop method and the operation after stopping depend on the SERVOPACK param-
eter settings.

• Controller Processing

The current movement command is continued.

Details and Cause

Any of the following is possible.
• A command was issued that caused a travel limit of the machine to be exceeded for one

of the following:
A command from a user program
Manual operation that exceeds the travel limit

• An error in the overtravel signal

Correction

• Check the following items:

Check the overtravel signal.
Check programmed and manual operation.

• After completing the above checks, return the axis to eliminate the overtravel condi-

tion.

Detection Timing

Anytime

Processing When
Warning Occurs

Movement commands cannot be executed.

Details and Cause

The power to the Servomotor was not turned ON even though bit 0 (Servo ON) of the
OW00 setting parameter was turned ON.
Any of the following is possible.
• The change in the Servo ON command from OFF to ON was not detected.
• There is an alarm in the SERVOPACK.
• The main circuit power supply to the SERVOPACK is OFF.

Correction

Turn ON the Servo ON command again.
Check the SERVOPACK for alarms and check the power supply status and stop signal
status.

Detection Timing

Anytime

Processing When
Warning Occurs

The current movement command is continued. Movement commands can be executed.

Details and Cause

This bit shows individual errors in MECHATROLINK communications.

Correction

When the communications error stops, normal status is recovered automatically.
If warnings occur frequently, reroute the MECHATROLINK cable, change the ground,
or implement other noise countermeasures.

Detection Timing

Anytime

Processing When
Warning Occurs

The power supply to the Servomotor is turned OFF and movement commands are not
executed.

Details and Cause

The stop signal (or an HWBB for

Σ-V/Σ-7 SERVOPACKs) was received by the SERVO-

PACK.

Correction

Confirm safety, and then disable the stop signal.
