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.
