Quick stop

Unlike the

Stop

function, quick stop (QSP) is required for a stop in the event of an error. If

quick stop is activated, the drive will be braked to standstill irrespective of the defined

setpoint within the deceleration time set.

Tip!
The quick stop can be set for many monitoring functions as an error response as

well ("quick stop by trouble").
The source which activated the quick stop function is shown bit-coded in C00159.

Activation of quick stop by the master control
Quick stop can be activated by the master control using the "

Quick stop

" command when

the operation is enabled.

The device state "

Operation enabled

" is changed to device state "

Quick stop active

".

 The active quick stop function can be deactivated again using the "

Enable operation

"

command.

Lenze parameters for the "Quick stop" basic function:

Note!

During quick stop, the drive carries out the setpoint generation and does not

follow the setpoint anymore defined by the master control!
If several drives carry out a coordinated motion by means of actual value

transfer, the quick stop function should only be used for the motion master

(master drive) in order to maintain the coordination.
