POINT
(1) (Note-1) : Make the forced stop input cable within 30m(98.43ft.).
The forced stop by the forced stop terminal of input module is also
possible.
(2) (Note-2) : Motion SFC program example is shown in the right record.
(3) (Note-3) : It is also possible to use a full wave rectified power supply as the
power supply for the electromagnetic brake.
(4) (Note-4) : It is also possible to use forced stop signal of the servo amplifier.
(5) (Note-5) : 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.
<Example> For control axis 1 and axis 2

(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
B
figure is shut off, it is also not possible to
communicate with the servo amplifier
C
.
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.
