Setting The Soft Stop Function; Setting The Ramp-Down Time - Siemens SIRIUS 3RW30 Manual

13.3 Setting the soft stop function

13.3 Setting the soft stop function
In "soft stop" mode, the natural stop process of the load is decelerated. The function is used
when the load must be prevented from stopping abruptly. This is typically the case in
applications with a low mass inertia or a high counter-torque.
13.3.1

Setting the ramp-down time

t potentiometer
You can set a ramp-down time with the t potentiometer. This determines how long power
should still be supplied to the motor after the ON command is removed. The torque
generated in the motor is reduced by means of a voltage ramp function within this ramp-
down time and the application stops smoothly.
If the potentiometer is set to 0, there is no voltage ramp during stopping (stop without load).
