can be enabled.
0.00–50.00Hz
When the actual speed is higher than the
reference speed, if the actual speed is higher
than (Reference speed + P28.08) and exceeds
this upper limit, the speed has to be adjusted.
0.00–50.00Hz
When the actual speed is lower than the
reference speed, if the actual speed is lower
than (Reference speed - P28.09) and the
window lower limit, the speed has to be
adjusted.
0–50000
Applicable only in master/slave mode 4, for
slave rotation speed regulation
