Setpoints and setpoint conditioning
The setpoint generally determines the motor speed.
Setpoints (Page 327)
The setpoint processing uses a ramp-function generator to prevent speed steps occurring and
to limit the speed to a permissible maximum value.
Setpoint processing (Page 338)
Technology controller
The technology controller controls process variables, e.g. pressure, temperature, level or flow.
The motor closed-loop control either receives its setpoint from the higher-level control - or from
the technology controller.

Motor control
The motor closed-loop control ensures that the motor follows the speed setpoint. You can
choose between various control modes.

Drive protection
The protection functions prevent damage to the motor, converter and driven load.
Drive protection (Page 404)
Increasing the drive availability
The drive can bridge temporary power failures or be switched on while the motor is rotating.

Saving energy
The converter enhances the efficiency optimization of the standard induction motor or
disconnects the power module from the system, if necessary.
