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