Description
The breakaway time determines the period during which the breakaway
voltage is to be present. Once the breakaway time has expired, the soft
starter begins its run-up procedure with the selected type of start, e.g. the
voltage ramp or torque control.
Select a breakaway time that is at least long enough to ensure that, after the
set time has elapsed, the motor does not stop again but continues to
accelerate in the selected start type immediately.
The parameter value "0" deactivates the breakaway pulse function.

The breakaway voltage is used to set the breakaway torque to be
generated. The breakaway torque can be up to 100% of the switch-on
torque generated during direct-on-line starting.
Select a breakaway voltage that is high enough to ensure that the motor
starts rotating as soon as the start command is issued to the soft starter.
