Quick stop QSP
The quick stop function is used to stop the drive independently of the setpoint input, within a time
to be set.
•
The Quickstop function is active if
MCTRL_bQsp_b
= TRUE
•
If the SB
DCTRL_DriveControl
is to trigger QSP, the QSP function must be programmed as
follows:
MCTRL_bQspOut_b
MCTRL_bNMSwt_b
MCTRL_nLoMLim_a
MCTRL_nHiMLim_a
C0907/3
C0906/4
C0906/3
C0907/2
OR
DCTRL_bQspIn_b
Any Variable

The torque limitation
MCTRL_nLoMLim_a
and
MCTRL_nHiMLim_a
are deactivated, i.e. the
drive runs at
±
100 % .
•
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
–
MCTRL_nPosLim_a
triggered with a value > 0% .
Stop!
If the field is weakened manually (
MCTRL_nFldWeak_a
< 100% ), the drive cannot supply the
maximum torque.
