POINT
(1) 1: Configure up the power supply circuit which switch off the electromagnetic contactor (MC) after detection alarm occurrence on
the PLC CPU.
(2) 2: It is also possible to use a full wave rectified power supply as the power supply for the electromagnetic brake.
(3) 3: When MR-J4-GF is used, to set the axis number of servo amplifier, set it using the axis select rotary switch of servo
amplifier. Refer to the servo amplifier instruction manual for details.
(4) 4: Refer to the servo amplifier instruction manual for selection of the circuit breaker and electromagnetic contactor.
(5) 5: The status of forced stop input signal can be confirmed with "[Md.50] Forced stop input". Be sure that the forced stop 24VDC
power supply is not used with the electromagnetic brake of the motor or the electromagnetic valve power supply.
(6) 6: The surge suppressor is recommended to be used for an AC relay or electromagnetic contactor (MC) near the servo amplifier.
Refer to the servo amplifier instruction manual for selection of the surge suppressor for wiring.
(7) 7: Wire the electromagnetic brake power supply and the control power supply using a separate power supply.

(Note-1): Be sure to shut off the both of main circuit power supply L1/L2/L3 and control power supply L11/L21 after disconnection of CC-
Link IE Field Network communication at the time of exchange of servo amplifier. At this time, it is not possible to communicate
between the servo amplifier and Simple Motion module. Therefore, be sure to exchange the servo amplifier after stopping the
operating of machine beforehand.
(Note-2): The dynamic brake is operated, and servomotor occurs to the free run when EM1 (forced stop) of servo amplifier turn OFF. At the
time, the display shows the servo forced stop warning (E6.1). During ordinary operation, do not used forced stop signal to
alternate stop and run. The service life of the servo amplifier may be shortened.
