9.2.40.8 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
z if the input MCTRL-QSP is triggered with HIGH.
z if the controller is triggered via the control words (DCTRL).
Function:
z If torque control has been selected, it will be deactivated. The drive is controlled by the speed
controller.
z The speed runs with the deceleration time set under C0105 to zero speed.
z The torque limitations MCTRL-LO-M-LIM and MCTRL-HI-M-LIM are deactivated.
z The phase 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.
