If using an encoder, ensure the encoder parameters are correctly aligned. An unaligned or faulty encoder can disrupt the identification sequence if the drive is set to perform a rotating identification. Fault Values: Decoding the Specific Diagnostics
: The drive is unable to provide enough torque to move the load because limits (p0640) are set too low.
: The load on the motor exceeds its torque capability, physically preventing it from turning. Incorrect Parameter Settings
Once your system is running, implement these best practices to prevent recurrence:
The drive continuously monitors several internal metrics to calculate a stall condition:
