3.10.2 Speed control
The Speed control serves to easily rotate the drive without setting control parameters or feedback
systems in the "Speed follower" mode:
How to easily rotate the motor:
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 inverter via the Enable controller button.
• Please observe that the inverter will not be enabled if other sources of controller inhibit
(e.g. RFR terminal) are active.
• The enabled drive now follows the defined speed setpoint.
• In order to prevent shocks or overload at higher setpoint changes, the speed setpoint is
lead via a linear ramp generator with adjustable acceleration/deceleration time.
•Via the Inhibit controller button, the inverter can be inhibited again, i.e. the motor
becomes torqueless and is coasting unless it already is at standstill.
