Diagnostics and Troubleshooting
Problem Cause/Solution/Troubleshoot
High peak current at either
start or stop
Check the brake timing such that the motor is not starting against
the brake and that the brake is not stopping the load.
For digital input speed control, the Speed Start Delay LF.70 can be
extended to prevent starting under the brake. For analog and serial
speed controls, this may need adjustment on the controller.
