Condition: the number of turns for the absolute encoder exceeds the range:
-32768 to +32767.
Cause: motor's rotation cycle exceeds the allowable range.
Check if the motor's number of turns while operating is within the range
between -32768 and +32767. If not, please execute homing again.
Cycle power on the servo drive.
Condition: the encoder temperature is over 85℃ (warning level), but still
under 100℃, which is within the protective range.
Cause: encoder temperature warning (85℃ -- 100℃).
Set P0.002 to 120d and check if the encoder temperature is identical to the
motor temperature. If the encoder temperature is too high, please improve
the heat dissipation or reduce the operating load. If the temperature
difference between the encoder and motor is over 30℃, please send the
motor back to the distributor.
Cycle power on the servo drive.
Condition: the sequence is wrong when reading the absolute position with
DIO.
Causes:
1. Time sequence is wrong.
2. Reading timeout.
1. Correct the time sequence for reading the data with DIO:
(A) DI.ABSQ switches to off after DO.ABSR is off.
(B) DI.ABSQ switches to on after DO.ABSR is on.
2. Check the duration from when DO.ABSR switches on to the time that
DI.ABSQ switches on and see if this duration is over 200 ms. The
correct procedure should be: when DO.ABSR switches on and after the
bit data of absolute position is ready, read DO.ABSD within 200 ms and
switch DI.ABSQ on. Then inform the servo drive that data reading is
complete.
