3.10.2 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.
