*1 Configure up the power supply circuit which switches off the electromagnetic contactor (MC) after detecting the alarm occurrence on the
*2 It is also possible to use a full wave rectified power supply as the power supply for the electromagnetic brake.
*3 Set the axis selection rotary switch of servo amplifier as follows to set the axis No. of servo amplifier.
● Axis 1: 0, Axis 2: 1, Axis 3: 2, Axis 4: 3
*4 Refer to the servo amplifier instruction manual for selection of the circuit breaker and electromagnetic contactor.
*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 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.
• Be sure to shut off the both of main circuit power supply L1/L2/L3 and control power supply L11/L21 after disconnection of
SSCNET communication by the connect/disconnect function of SSCNET 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 "E6.1" (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 control power supply of servo amplifier is shut off, it is not possible to communicate with the servo amplifier after
When the control power supply L11/L21 of the servo amplifier B in the figure is shut off, it is also not possible to communicate
with the servo amplifier C.
If only a specific servo amplifier main circuit power supply is shut off, be sure to shut off the main circuit power supply L1/L2/
L3, and do not shut off the control power supply L11/L21.
