The figure below shows the principle of the loaded motor:
Figure 3-3 Principle of soft run-down on motor starters with mechanical braking
You can find more information on the "Brake holding time on stopping" in the chapter
"Mechanical braking".
During the parameterized starting time, the motor terminal voltage is increased linearly from
the starting voltage to the full line voltage. A setting of 0s means that the motor is switched
on with a voltage ramp of 100 milliseconds to reduce the peak inrush current.
