SINAMICS V20 and scaled into a frequency
setpoint (0 to 50Hz) there.
The lower and upper limit of the frequency
setpoint depend on the minimum and
maximum motor speed which has been
configured in SINAMICS V20 (P1080=min and
P1082=max).

The duration of the acceleration and

time and ramp-down time (P1122=ramp-up
time and P1121=ramp-down time) configured
in SINAMICS V20.
