Parameters 155
Torque
Torque control. The torque reference used is
26.74
Torque
ref ramp out
(output of the torque reference chain).

Minimum
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 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.
