4.3.3 Inspecting a Switching Power Supply Module
The Switching Power Supply module rectifies AC200V (or the local equivalent) and
outputs DC24V. The DC24V is converted by the DPB to supply power to: VCC (
+
5V),
the motor driver (
+
5V) and the encoder (5V).
Inspect the Switching Power Supply module by following the steps as described below:
(1) Turn ON the Drive Unit(s).
(2) Check on the Drive Unit’s front panel if the POWER LED (green) is ON.
If this lamp is either OFF or dim, suspect that the
+
24V power output is not normal.
(3)
Check on the Drive Unit’s front panel to make sure that the LED (green) on the left
of and behind the ERROR LED (red) is ON. When this lamp is OFF, either the
+
24V or
+
5V power output may not be normal, or the
+
24V power voltage may be
too low.
