Revision December, 2017
Incremental motor does not support the absolute function.
1. Check to see if your servo motor has an incremental or absolute
encoder.
2. Check the setting of P2.069 and correctly set the value. Set P2.069 to 0
if your encoder does not use the absolute function.
Set P2.069 to 0 and then cycle power on the servo drive.
Condition:
1. Motor in use for the first time.
2. Power supply of the servo drive is cut off and the battery is drained, or
the battery has been replaced and the absolute position is lost.
Cause: the motor is used for the first time or the absolute position is lost due
to changing the battery.
Check if the absolute position is correctly initialized (see Section 10.3.1).
This alarm is cleared after you complete the initialization of the absolute
position.
Command is not completed when the barcode is written to the encoder.
Check if the wiring is correct and firmly connected. If not, please correctly
connect the wiring again.
Cycle power on the servo drive.
When encoder is powered by the servo drive: over 8800 rpm;
When encoder is powered by the battery: over 10000 rpm.
1. Check if the motor is well grounded; make sure the power cable is
grounded to the heat sink of the servo drive.
2. Make sure the encoder cable is separated from the power supply or any
high-current cable to avoid interference.
3. Use shielded cable for the encoder and pull out the shielded mesh and
