654 ENABLE RS IDENTIFICATION 6 (2.6.24.5)
With this parameter its possible to disable Rs identification during DC brake start. The
parameter default value is 1 (Yes).
655 MODULATION LIMIT 6 (2.6.23.34)
This parameter can be used to control how the drive modulates the output voltage. Reducing
this value limits the maximum output voltage. If a sinusoidal filter is used set this parameter
to 96%.
