Yaskawa MP2200 Machine Controller - Manual (Page 505)

10.1 Motion Errors
10-19
( 16 ) Servo Driver Communication Error (IL††04 Bit 17)
( 17 ) Servo Driver Command Timeout Error (IL††04 Bit 18)
The above error occurs when Module allocations of SERVOPACK have been completed and power is
not being supplied to the SERVOPACK for MECHATROLINK communication.
( 18 ) ABS Encoder Count Exceeded (IL††04 Bit 19)
Detection Timing
• Detected by the communication control section when communication is synchronized between the MP2200/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 has stopped (the cable is disconnected or the power supply to the SERVOPACK is
OFF).
Correction
• Check the MECHATROLINK cable and reset the alarm.
Detection Timing
• Detected during execution of motion commands.
• Detected at the MECHATROLINK communication control section when 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 the connections between the MP2200/MP2300 and SERVOPACK for MECHATROLINK communication.
• Check for alarms in the SERVOPACK for MECHATROLINK communication.
INFO
Detection Timing
• Detected by the position management section when power is turned ON, but only when an absolute encoder is used, a
finite length axis is set, and the electronic gear used.
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, and other motion fixed parameters.
