F090 MId Param.
An error occurred when attempting to change
a parameter from the standstill measurement
or the rotating measurement (Mot ID).
Power down and power up again. If it re-
occurs, replace the CU.
F091 MId Time
The rotating measurement takes longer than
programmed in a measured status. Possible
causes:
• Load torque too high
• Load torque not uniform
• Ramp-function generator disabled
Eliminate the cause and re-start the
measurement (power up the converter again).
If it re-occurs, replace the CU.
