can vary greatly due to different loads. Determine the values for the maximum brake time.

To do this, input the following settings under the point "Configure measurement data".

The two speed values are now immediately recorded for 2.55 s as soon as you actuate the

button. During this time, you remove the controller enable and so determine the

brake time from the measurement curve. This is stored under the point "Measurement
data".

FCT PlugIn Version V1.0

The maximum time until the drive stands still after controller
enable at speed = 0 is 499.2 ms. If this time is exceeded, the
Quick Stop delay must be set to a higher value.

FCT PlugIn Version V1.1

The maximum time until the drive stands still after controller
enable at speed = 0 can be set via the ‚maximum switch off
delay‛ from 2 … 10000 ms.

A possible measurement curve could look as follows.
