3.5.43.8 Quick stop QSP
The QSP function is used to stop the drive within an adjustable time independently of the setpoint
selection.
The QSP function is active
l if the input MCTRL−QSP is triggered with HIGH.
l if the controller is triggered via the control words (DCTRL).
Function:
l If torque control has been selected, it will be deactivated. The drive is controlled by the speed
controller.
l The speed runs with the deceleration time set under C0105 to zero speed.
l The torque limitations MCTRL−LO−M−LIM and MCTRL−HI−M−LIM are deactivated.
l The angle controller is activated. If the rotor position is shifted actively, the drive generates a
torque against this displacement if:
– C0254 is not zero
– The input MCTRL−PHI−LIM is triggered with a value > 0 %.
( Stop!
If the field is weakened manually (MCTRL−FLD−WEAK < 100%), the drive is unable
to generate the max. torque.
