5 Enabling the servo drive and selecting the set values
5.2.2 Speed-controlled mode (speed control)
In speed-controlled mode, a specific speed setpoint is specified. The servo drive
determines the actual speed n_actual by evaluating the encoder data. To ensure
compliance with the speed setpoint, the current setpoint i_set is determined.
To activate the speed-controlled mode, "Speed control" must be selected in the
"Commands" window.
The menu Operating mode/Controller overview provides a simplified control-related
overview of this operating mode to help you with using the associated menus.
Figure 25: "Controller overview" window
This operating mode is used if the servo drive is controlled by a superordinate control
system, e.g. via an analogue input or via a fieldbus, so that positioning processes are
calculated by the control system, and if a superordinate, external position control circuit
and an external positioning control system are present.
