Combination of selections
and
: the
torque selector compares the speed controller output
(
25.1 Torque reference speed control
) and the torque
reference (
) and selects the
smaller of the two.
If speed error becomes negative, the drive follows the
speed controller output until speed error becomes
positive again.
This prevents the drive from accelerating uncontrollably
if the load is lost in torque control.
