Speed control

Via the Speed control tab, simply make the drive rotate in the "Speed follower" operating mode

without the need to set control parameters or feedback systems:

How to make the motor rotate in its most basic way:

1. Set the desired speed setpoint in [%] based on the reference speed, e.g. directly in the

Setpoint PC input field or via the slider.

• Via the -- / 0 / ++ buttons, the currently set speed setpoint can be reduced/increased in

steps of 10 percent or set to zero.

• Via the Set setpoint A/B buttons, the speed setpoint can be set to a previously set

constant value A/B.

2. To start the speed follower:

Enable the controller via the Enable controller button.

• Please note that the controller is only enabled if no other sources of a controller inhibit

(e.g. terminal RFR) are active.

• The enabled controller is now following the selected speed setpoint.
• To avoid shocks or overload in case of great setpoint changes, the speed setpoint follows

a linear ramp generator with adjustable acceleration/deceleration time.

• Via the Inhibit controller button, the controller can be inhibited again, i.e. the motor

becomes torqueless and is coasting unless it already is at standstill.
