Safety functions
The safety functions fulfill increased requirements regarding the functional safety of the drive.
Safe Torque Off (STO) safety function (Page 215)
Setpoints and setpoint conditioning
The setpoint generally determines the motor speed.
The setpoint processing uses a ramp-function generator to prevent speed steps occurring and
to limit the speed to a permissible maximum value.
Setpoint calculation (Page 243)
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.
PID technology controller (Page 252)
Motor control
The motor closed-loop control ensures that the motor follows the speed setpoint. You can
choose between various control modes.
The inverter has various methods to electrically brake the motor. When electrically braking,
the motor develops a torque, which reduces the speed down to standstill.
