Soft stopping
Operating principle
A voltage ramp is used to implement a smooth ramp-down. With the "voltage ramp" stopping
function, the motor voltage is decreased along a linear, negative voltage ramp until the motor
stops.
Application
●
Drives that abruptly come to a stop when switched off, thereby damaging the transported
goods.
●
E.g. bottle filling plants

Description
Stopping time
The length of the stopping time defines the time within which the motor
voltage is reduced from line voltage to 0 V. It may take longer for the motor
to actually coast down to a standstill.
The parameter value "0" causes the motor to be shut down immediately
without a down ramp.
