Cause : Selected signal has fallen below the user underload curve.

Programmable fault:
37.04 -  ULC underload actions

1. Check for any operating conditions decreasing the monitored signal (for example, loss of load if the torque or current is being monitored).
2. Check the definition of the load curve (parameter group 37 User load curve).
