If the peak current limit is being reached, this may be due to:
Incorrect Motor Data. Refer to Motor Data Incorrect for additional
information.
Encoder Position Incorrect. Refer to Encoder/Motor Pole Position

Mechanical Issues (eg. Brake not releasing)
For open loop induction motors, the LC32 Low Speed Torque Boost
