Cause : The hybrid motor drive detects excessive output current.
1. Check if the hybrid servo motor is
stalled.
2. Replace the hybrid servo drive with a
larger output capacity model.
3. Set Pr00-04=29, observe if the value
returns to zero after every molding
cycle. If the number accumulates to
100, OL occurs
4. The causes of this error could be
loose contact/ disconnection between
encoder, servo drive and the motor.
This error also occurs when a motor
or an oil pump is stalled which make
unusual rotating speed and over
current.
