2.5 External Circuit Design
*1 Configure up the power supply circuit which switches off the electromagnetic contactor (MC) after detecting the alarm occurrence on the
CPU module.
*2 It is also possible to use a full wave rectified power supply as the power supply for the electromagnetic brake.
*3 It is also possible to perform the forced stop using the emergency stop function of the Motion module.
For details, refer to "Functions to Limit the Control" in the following manual.
MELSEC iQ-F FX5 Motion Module/Simple Motion Module User’s Manual (Application)
*4 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.
*5 Refer to the servo amplifier instruction manual for selection of the circuit breaker and electromagnetic contactor.
*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.
*7 Wire the electromagnetic brake power supply and the control power supply using a separate power supply.
Precautions
• Be sure to shut off power supply L1/L2/L3 after disconnection of CC-Link IE TSN communication by the connect/disconnect
function of CC-Link IE TSN 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.
• The dynamic brake operates and servomotor occurs to the free run when EM1 (forced stop) of the servo amplifier is turned
OFF. At the time, the display shows "0E6.1" (Forced stop warning). During ordinary operation, do not use EM1 (forced stop)
of the servo amplifier to alternate stop and run. The service life of the servo amplifier may be shortened.
• When the power supply of servo amplifier is shut off, it is not possible to communicate with the servo amplifier after that.
