The converter can control a motor holding brake. The motor holding brake holds the motor in
position when it is switched o󹪜.

Safety functions
The safety functions ful󹪝ll increased requirements regarding the functional safety of the drive.

Setpoints and setpoint processing
The setpoint normally de󹪝nes the motor speed.
Setpoints (Page255)
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265)
Technology controller
The technology controller controls process variables, e.g. pressure, temperature, level or
󹪞ow. The motor control receives the setpoint either from the higher-level control or from the
technology controller.

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

The converter provides several methods to brake the motor electrically. During electrical
braking, the motor develops a torque that reduces the speed to standstill.
