Quick stop (QSP)
By means of the QSP function, the drive can be stopped within an adujstable time,
irrespective of the setpoint selection. The QSP function is active if:
ƒ
SPEED−QSP.Set1 (C7411/17) = TRUE
or
ƒ
SPEED−QSP.Set2 (C7411/18) = TRUE
Function:
If a torque control has been selected, it is switched inactive. The drive is guided by the speed
controller. The speed is reduced to zero within the deceleration time set under C0105. The
torque limitation SPEED−MCTRL.NegLoMLim (C7431/3) and SPEED−MCTRL.HiMLim
(C7431/4) is switched inactive, i. e. the operation runs with ±100 %. The phase controller
is switched active, achieving a drift−free standstill. If the rotor position is actively displaced,
the drive creates a torque against the displacement if
