Servo ON Enable Input (ON_EN1 and 2)
This function divides the system into multiple servo areas and turns ON the servo power for
each area.
In the standard specification, this is short-circuited by a jumper lead.
1. Remove jumper leads between CN28-7 and -8, and between CN28-9 and -10 of the
power ON unit (JZRCR-XSU02).
2. Connect the switch 1 for servo area to the servo ON enable input (ON_EN1) across
CN28-7 and -8, the switch 2 to the servo ON enable input (ON_EN2) across CN28-9
and -10. Make a connection so that both of these switches turn ON/OFF simulta-
neously. When both of ON_EN1 and 2 are ON, the servo power supply turns ON.
When only one is ON, an alarm occurs.
