If LimitSwitchStopMode (06.002) = 0 then when Limitswitchactive (10.066) is activated the motor is stopped without ramps (under dc injection control).
If LimitSwitchStopMode (06.002) = 1 then the motor is stopped with the currently selected ramp rate.

If SupplyLossMode (06.003) > 0 and the D.c.LinkVoltage (05.005) falls below SupplyLossDetectionLevel (06.048) then the supply loss condition is detected. If SupplyLossMode (06.003) =
2 (ride through) the supply loss system will attempt to control the D.c.LinkVoltage (05.005) to a level just below the SupplyLossDetectionLevel (06.048) using a d.c. link voltage controller
which provides a torque producing current reference to the current controllers to regulate the power flow into the d.c. link. Therefore CurrentControllerKpGain (04.013) and
CurrentControllerKiGain (04.014) must be set up correctly for the application. When the supply is reapplied it must be at a level that is high enough for the D.c.LinkVoltage (05.005) to rise
above SupplyLossDetectionLevel (06.048) plus a hysteresis margin. This will disable the supply loss controller and the drive will return to normal operation. The table below gives the d.c. link
voltage levels used by the supply loss detection system for different drive voltage ratings.

0: Disable
No supply loss detection is provided by monitoring the D.c.LinkVoltage (05.005). The drive will continue to operate normally unless the under voltage condition is detected.
1: Ramp Stop
The action taken by the drive is the same as for ride through mode, except that the ramp down rate is at least as fast as the currently selected deceleration ramp and the drive will continue to
decelerate and stop even if the supply is re-applied. If StopMode (06.001) = 3 or 4 (i.e. d.c. injection) the drive will use ramp mode to stop on loss of the supply. If StopMode (06.001) = 2 (i.e.
ramp stop followed by injection) the drive will ramp to a stop and then attempt to apply d.c. injection. The ramp down rate is at least as fast as the currently selected deceleration ramp and the
drive will continue to decelerate and stop even if the supply is re-applied. Once the sequencer state machine has reached the DISABLE state the drive can restart provided the necessary
controls are still active to initiate a start.
2: Ride through
The drive attempts to control the d.c. link voltage to take energy from the motor and load inertia to ride through the Supply loss condition for as long as possible.

This parameter changes the functions of the input terminals which are normally associated with the enabling, starting and stopping the drive. This also writes to EnableSequencerLatching
