Check for any operating conditions
increasing the monitored signal (for
Selected signal has exceeded the user
overload curve.

example, the loading of the motor if the
torque or current is being monitored).
Check the definition of the load curve
(parameter group 37 User load curve).
Check for any operating conditions
decreasing the monitored signal (for
Selected signal has fallen below the user
underload curve.
ULC underloadA8BF
example, loss of load if the torque or
current is being monitored).
Check the definition of the load curve
(parameter group 37 User load curve).
Check the auxiliary code. The code
indicates which fan is to be replaced.
A cooling fan has reached the end of its
estimated lifetime.
