Here, the percentage of current threshold (based on the motor
current 33,031) can be adjusted at the start of integration.

max: 128000
Def: 2
Only for asynchronous motors.
Is the time interval during which the drive is maintained with
direct current after stoppage of the braking ramp.
Switching frequency
The internal switching frequency (clock frequency) can be varied to control the
power unit. A high setting value leads to noise reduction in the motor, but also to
increased EMC emission and higher losses in the drive controller.

Def: 2
Selecting the switching frequency of the inverter.
1 = 16 kHz
