Switching frequency; slip gain; voltage reserve; flux braking;
anti-cogging (signal injection); IR compensation.
Defines the switching frequency of the drive that is used as
long as the drive does not heat too much. See section
on page
.
Higher switching frequency results in lower acoustic noise-
Note:
If you have a multimotor system, contact your local
ABB representative.

Defines the relative output voltage boost at zero speed (IR
compensation). The function is useful in applications with a
high break-away torque where vector control cannot be
applied.
