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: It is also possible to perform the forced stop using forced stop terminal of the servo amplifier.
(4) 4: Set the axis selection rotary switch of servo amplifier as follows to set the axis No. of servo amplifier.
• Axis 1: 0 • Axis 5: 4
• Axis 2: 1 • Axis 6: 5
• Axis 3: 2 • Axis 7: 6
• Axis 4: 3 • Axis 8: 7
(5) 5: The status of forced stop input signal can be confirmed with "[Md.50] Forced stop input". Be sure that the forced stop 24 V DC
power supply is not used with the electromagnetic brake of the motor or the electromagnetic valve power supply.
(6) 6: Refer to the servo amplifier instruction manual for selection of the circuit breaker and electromagnetic contactor.
(7) 7: 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.
(8) 8: Wire the electromagnetic brake power supply and the control power supply using a separate power supply.

(Note): If the emergency stop signal of Simple Motion module turns OFF when setting of "[Pr.82] Forced stop valid/invalid selection" to "0:
Valid", servomotor is stopped with dynamic brake. (The LED display of servo amplifier indicates "E7.1" (Controller forced stop input
warning).)
