Cause Remedy
The device has detected a motor current which exceeds
the maximum current limit at permanent switching
frequency of the inverter.
• If a permanent switching frequency inverter is set, a
certain limit arises for the maximum current,
depending on the setting. If this current limit is
exceeded due to a load impulse or overload, an error
message is displayed.
• Observe the maximum current setting depending on
the set switching frequency of the inverter.
• Reduce the required load or setting of the dynamic
switching frequency if necessary.

Cause Remedy
The output of the speed controller has reached the
internal limit value. In this state, the speed controller is
not able to correct the system deviation anymore.
• Only in "VFCplus: V/f linear/quadratic + encoder" or
SLVC (vector control) operation.
• Observe load requirements.
• Correct dimensioning or reduce setpoint generation
dynamics if necessary.

Cause Remedy
Maximum speed for chopper frequency has been
reached.
• The maximum speed has been exceeded depending
on the switching frequency.
Select the correct maximum speed as a function of the
switching frequency.
