The quick stop deceleration in velocity mode is set with object
velocity quick stop. Ob-
ject
velocity quick stop consists of delta speed in RPM and delta time in seconds.
The gradient of the frequency in the deceleration period is written to parameters
Emergency Stop (clockwise)
424 and
Emergency Stop (anti-clockwise)
425 (data set
5, all data sets in RAM only !). Both parameters are set to the same value.
The values of p.424 and p.425 are converted internally to a frequency/sec value, taking
into account the parameter
No. of Pole Pairs
373 (in data set 1 !).
The gradient is changed internally by altering the objects delta time or delta speed.
