Figure 4-76
● Speed control
The speed control of a variable-speed drive has the task of following the speed according
to a specified setpoint (reference variable) as precisely as possible and without
overshoot.
● Torque control
With torque control, the torque is the reference value and the actual torque value should
follow the torque setpoint with as little ripple as possible and without delay.
Selecting the control type
1. Select one of the following control types (p1300) in the drop-down list:
– Speed control with encoder
– Speed control without encoder
– Torque control with encoder
If you have selected a control type with encoder, this encoder is now shown in the
diagram.
