Wiring Example for Three-Phase, 200-VAC Power Supply Input
The following diagram shows the wiring to stop both Servomotors when there is an alarm for
one axis.
WARNING
Even after you turn OFF the power supply, a high residual voltage may still remain in the
SERVOPACK. To prevent electric shock, do not touch the power supply terminals after you
turn OFF the power. When the voltage is discharged, the CHARGE indicator will turn OFF.
Make sure the CHARGE indicator is OFF before you start wiring or inspection work.
