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.
