Figure 7-19 Speed controller with droop
Precondition
● All connected drives must be operated with vector and speed control (with or without
speed actual value encoder).
● The setpoints at the ramp function generators of the mechanically connected drives must
be identical; the ramp function generators must have identical ramp-up and ramp-down
times.
