2.12.11 Quick stop (QSP)
The QSP function is used to stop the drive independently of the selected setpoint within an adjustable
time interval.
·
The QSP function is active if MCTRL_bQsp_b is set = 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

Function:
·
If torque control is selected, it will be deactivated. The drive is controlled by the speed
controller.
·
Speed is reduced to 0 within the deceleration time set under C0105:

·
The torque limits MCTRL_nLoMLim_a and MCTRL_nHiMLim_a are deactivated, i.e. the drive is
operated with
± 100 %. ( ^ 2−50)
·
The phase controller is activated. If the rotor position is shifted actively, the drive generates a
torque against this displacement if
– C0254 is set non−zero,
– MCTRL_nPosLim_a is triggered with a value > 0 %.
Stop!
If the field is weakened manually (MCTRL_nFldWeak_a < 100 %), the drive cannot supply the
maximum torque.
