Troubleshooting Motion Errors
12-25
( 6 ) Bit 6: Positioning Time Over
The above check is not performed if the Position Complete Timeout (OW
26) is set to 0.
( 7 ) Bit 7: Excessive Positioning Moving Amount
( 8 ) Bit 8: Excessive Speed
( 9 ) Bit 9: Excessively Following Error
The above check is not performed if the Deviation Abnormal Detection Value (OL
22) is set to
0.
Detection Timing
• Positioning was not completed after completing pulse distribution.
Processing when
Alarm Occurs
• The current command was ended forcibly.
• The Command Error Occurrence in the Servo Module Command Status (IW
09 bit 3) will turn ON.
Error and Cause
One of the following is possible.
• The position loop gain and speed loop gain are not set correctly, creating poor response.
• The Position Complete Timeout (OW
26) is too short.
• The capacity of the motor is insufficient for the machine load.
• Connections are not correct between the SERVOPACK and the motor.
Correction
Check the following.
• Check the SERVOPACK gain parameters.
• Check connections between the SERVOPACK and the motor.
• Check the motor capacity.
• Check the Position Complete Timeout (OW
26).
Detection Timing
• Enabled when the electronic gear is used and detected when positioning command is executed.
Processing when
Alarm Occurs
• The move command is not executed.
• The Command Error Occurrence in the Servo Module Command Status (IW
09 bit 3) will turn ON.
Error and Cause
• A move command (commands for positioning, external positioning, or STEP operation) was executed that
exceeded the limit of the positioning moving amount.
Correction
• Check the moving amount for the axis being positioned.
Detection Timing
• Enabled when the electronic gear is used and detected when positioning command is executed.
Processing when
Alarm Occurs
• The move command is not executed.
• The Command Error Occurrence in the Servo Module Command Status (IW
09 bit 3) will turn ON.
Error and Cause
• The limit to the moving amount that can be distributed during one scan has been exceeded.
Correction
• Check the moving amount for the axis that is being subjected to position control.
Detection Timing
• Detected during execution of positioning commands (commands for positioning, external positioning,
STEP operation, JOG operation, etc.).
• Detected during execution of phase control commands.
Processing when
Alarm Occurs
• The move command is not executed.
• The Command Error Occurrence in the Servo Module Command Status (IW
09 bit 3) will turn ON.
Error and Cause
One of the following is possible.
• The position loop gain and speed loop gain are not set correctly, creating poor response.
• The Deviation Abnormal Detection Value (OL
22) is too small.
• The capacity of the motor is insufficient for the machine load.
• SERVOPACK failure
Correction
Check the following and correct the problem. If the problem persists, contact the maintenance department.
• Check the position loop gain and speed loop gain.
• Check the Deviation Abnormal Detection Value (OL
22).
• Check the motor capacity.
