(see header for parameter U641 ff.)
Off-load switching is recommended to increase the service life of the rotor
contactors.
A disadvantage of off-load switching of rotor contactors: there is a torque-
free interval, and this may lead to a deviation in the speed.
Whenever a rotor contactor is switched in, the firing pulses are disabled for
the time set at index 001 (zero current interval).
Whenever a rotor contactor is switched out, the firing pulses are disabled
for the time set at index 002 (zero current interval).

Preventing current peaks during rotor stage stepping:
To prevent excessive stator current values occurring when switching in the next rotor contactor, it is desirable, at the same time as the
contactor is switched in (delayed by the time set at U640 index 003), to reduce the I component of the speed controller by roughly the
same proportion by which the rotor resistance is also reduced.
