Cause Remedy
The output of the speed controller has reached the
internal limit value. In this status, the speed controller is
not able anymore to correct the system deviation.
• Only during "Closed loop" operation or with vector
control (SLVC).
• 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.

Cause Remedy
Cross current controller limitation is active. • Observe load requirements.
• Correct dimensioning or reduce setpoint generation
dynamics if necessary.
• Check parameter setting of the current controller
with regard to the motor controllers (e.g. reduce Vp).
