3 DESIGN
POINT
1) (Note-1) : The following is the Motion SFC program example.
2) (Note-2) : It is also possible to use a full wave rectified power supply as the power
supply for the electromagnetic brake.
3) (Note-3) : It is also possible to use forced stop signal of the servo amplifier.
4) (Note-4) : It recommends using one leakage breaker for one servo amplifier. When electric
power is supplied to multiple servo amplifiers for one leakage breaker, select the
wire connected to the servo amplifier according to the capacity of the leakage
breaker.

(Note-1) : When the control power supply of servo amplifier is shut off, it is not possible to communicate with the servo amplifier after that.
Example) When the control power supply L11/L21 of servo amplifier in above
communicate with the servo amplifier
If only a specific servo amplifier 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.
(Note-2) : Be sure to shut off the both of main circuit power supply L1/L2/L3 and control power supply L11/L21 at the time of exchange of
servo amplifier. At this time, it is not possible to communicate between the servo amplifier and Motion controller. Therefore, be
sure to exchange the servo amplifier after stopping the operating of machine beforehand.
