6.18 Quick stop (QSP)
The quick stop function serves to brake the drive to standstill within an adjustable
deceleration time. The function is triggered by:
ƒ Control word bit 3 (QSP) = 1 (TRUE)
ƒ LOW level at X6/DI1
The deceleration time for the braking process can be set with C0105 in the GDC parameter
menu under Motion
W Machine parameter.

Behaviour when reaching the current limit
The actual quick stop deceleration time prolongs if C0105 is set so shortly that the
controller must operated at its current limits (I
max
, M
max
). The following error occurring in
this case in the position control loop is automatically modified internally so that the drive
does not reverse when reaching standstill to process the following error but rests at
standstill. Thus, the position control loop provides for a drift−free standstill at quick stop
(QSP).

Tip!
The quick stop function may require a setting of the position controller gain
under C0254.
