Wiring for servo power-on and other signals

*1. The brake release output signal as shown in Fig. 4.1 is for 2-axis servo units. For 1-axis servo
units, use only pins 14 and 15. For 2-axis servo units, use pins 14 and 15 for the first axis, and
pins 16 and 17 for the second axis.
*2. If the voltage of power input to the PS module is 100-120 VAC, short the JUMPER120 VAC
ONLY terminals together.
*3. To use the UPS module, short the On/Off terminals together. Otherwise an alarm would result.
*4. To use the battery module, insert a 15-A fuse in its fuse holder. Otherwise an alarm would result.
When inserting a fuse, a spark may occur (if the battery is in the charged state). Don’t worry
about the spark since it’s quite safe to you and the module.
*5. To make the UPS, emergency, and NC-ready functions available, program the necessary
sequences in the PLC. Once the shutdown sequence has been programmed, disconnecting or oth-
erwise disabling the UPS module would cause a switched-on NC to shutdown soon. To make the
NC powered up normally, always keep the UPS module functional.
