l If the actual phase is lagging, the drive is accelerated
l If the actual phase is leading, the drive is decelerated, until the desired phase synchronization
is achieved.
The influence of the phase controller consists of:
l Phase difference multiplied by the P-gain C0254
l Additional influence via analog signal at MCTRL-P-ADAPT
l limit of the phase controller output to  MCTRL-PHI-LIM
Limitation of the phase controller output
This limits the maximum speed-up of the drive in the event of large phase differences.
7.6.47.8 Quickstop QSP
The quick stop function is used to stop the drive independently of the setpoint input, within a time
to be set.
The quick stop function is active,
l if the input MCTRL-QSP is triggered with HIGH.
l if the controller is triggered through the control words (DCTRL).
Function:
l If torque control is selected, this will be deactivated. The drive is controlled by the speed
controller.
l The speed decelerates with the deceleration rate set under C0105 to zero speed.
l The torque limits MCTRL-LO-M-LIM and MCTRL-HI-M-LIM are deactivated.
l 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 cannot supply the
maximum torque.
