200 Parameters
Maximum Combination of selections Speed and Torque: the torque
selector compares the speed controller output (
25.01 Torque
reference speed control ) and the torque reference ( 26.74
Torque ref ramp out ) and selects the greater of the two.
If speed error becomes positive, the drive follows the speed
controller output until speed error becomes negative again.
This prevents the drive from accelerating uncontrollably if the
load is lost in torque control.
