The related conguration and description is as follows:
Select the ARD with the nominal output power equal to or larger than the rated motor power.
Monarch 380V ARD outputs the single-phase emergency voltage between the R and T
phases to the control cabinet. Note that for ARDs of other brands, the phases that output the
emergency voltage may be different.

Shorting PMSM Stator
Shorting PMSM stator means shorting phases UVW of the PMSM, which produces
resistance to restrict movement of the elevator car. In field application, an auxiliary NC
contact is usually added to the NO contact of the output contactor to short PMSM UVW
phases to achieve the effect. It is feasible in theory but may cause overcurrent actually.
Due to poor quality of the contactor and wiring of adding the auxiliary contact, the residual
current of the controller is still high when the outputs UVW are shorted at abnormal stop.
This results in an overcurrent fault and may damage the controller or motor.
Monarch's shorting PMSM stator scheme requires installation of an independent contactor
for shorting PMSM stator. The shorting PMSM stator function is implemented via the NC
contact of the relay. On the coil circuit of the RUN contactor, an NO contact of the shorting
PMSM stator contactor is connected in serial, to ensure that output short-circuit does not
occur when the parameter setting is incorrect.
The following gure shows wiring of the independent shorting PMSM stator contactor.
