Troubleshooting Motion Errors
12-27
( 14 ) Bit 17: Servo Driver Communication Error
( 15 ) Bit 18: Servo Driver Command Timeout Error
The above error occurs when Module allocations of SERVOPACK for MECHATROLINK commu-
nication have been completed and the power is not being supplied to the SERVOPACK.
( 16 )
Bit 19: ABS Encoder Count Exceeded
Detection Timing
• Detected by the communication control section when communication is not synchronized between the
MP2300 and SERVOPACK.
Processing when
Alarm Occurs
• The current command will be aborted.
• The SERVOPACK will be Servo OFF status.
Error and Cause
• MECHATROLINK communication stopped because the cable was disconnected or the power supply to
the SERVOPACK was turned OFF.
Correction
• Check the MECHATROLINK cable and reset the alarm.
Detection Timing
• Detected during execution of each motion commands.
• Detected by the MECHATROLINK communication control section when the Servo command responses
are checked for each process.
Processing when
Alarm Occurs
• The current command will be aborted.
Error and Cause
• The MECHATROLINK Servo command did not complete within the specified time (5 s).
Correction
• Check for alarms in the SERVOPACK for MECHATROLINK communication.
Detection Timing
• Enabled only when an absolute encoder is used for a finite length axis, and the electronic gear used.
Detected by the position management section when power is turned ON.
Processing when
Alarm Occurs
• The absolute position information read from the absolute encoder when the SEN signal turned ON is
ignored.
Error and Cause
• An operation error occurred when the absolute position information read from the absolute encoder is
converted from pulses to reference units at power ON.
Correction
• Check the gear ratio, number of encoder pulses for other motion fixed parameters.
