Boost mode can be activated if an increased breakaway torque is required.
If boost mode is activated, the motor is activated with the boost voltage U
B
after en-
abling before the soft start begins. After the boost time t
B
has elapsed, the soft start
phase commences with the parameterized starting voltage U
