5.1.11 Jump Frequencies
Allows the “jumping” of critical frequencies so that the motor can operate without resonant vibrations caused by
some machine systems. This is also used for deadband control. A setting of 0.0 Hz disables this function.

5.1.12 Field Forcing
This function compensates the delaying influence of the motor time constant when changing the excitation current
reference and improves motor responsiveness. Field Forcing has no effect during DC Injection Braking.

Field Forcing Limit
Maximum level at which the Field Forcing function can
boost the excitation current reference. The value is set
as a percentage of the motor no load current. This
