5. Switching Power Supply Module
5.1 Layout and Functions
Switching Power Supply Module 1: AES100W-24
Switching Power Supply module 1 rectifies AC200V (or the local equivalent) and outputs
+24V. The +24V is converted by the DPB to supply power to the control power
sources: the motor driver ( - 5V) and the encoder (5V).
Switching Power Supply Module 2: NSP7-100-X2S2
Switching Power Supply module 2 rectifies AC200V (or the local equivalent) and outputs
+ 12V, +5V.

5.2 Inspection
Inspect the Switching Power Supply modules by following the steps below:
(1) Turn ON the Controller.
(2) From the Controller's front panel, check if the POWER LED (green) is ON.
NOTE
(3) From the Controller's front panel, check if the RUN LED (green) is blinking.
NOTE
RC420 Rev.9
If this LED is either OFF or dim, suspect that the + 24V power output is not normal.
If this LED is not blinking or it is dim, the +5V and +12V power outputs may be not
normal.
