533 SlewRateTimeLimt
Defines the time limit in seconds during which torque producing voltage (Vqs) regulator output variations are
limited by each slew rate at the transition where the Vqs regulator turns on. The same time limit is applied at
the transition to the slip regulator when the slip regulator turns on. A value of zero disables the slew rate
function on both the Vqs regulator output and the slip regulator output. Par 553 defines the slew rate for the
slip regulator and Par
586 [IdsCmd Slew Rate] defines the slew rate for the Vqs regulator.
Notes: This parameter was added for firmware version 3.001. This parameter was renamed from “Flux Gain
Adjust” to “SlewRateTimeLimit”, the default value was changed to “10.0” and the minimum value was
changed to “0.0” for firmware version 4.001.
