3.3.1 Power-On
Connect the commercial power supply and the servomotor to the servo amplifier.
For the wiring method, refer to "CHAPTER 2 WIRING."
 Supplying commercial power
Operate MCCB/ELCB to supply power.
Supply main power simultaneously or later to the control power.
If necessary, insert an electromagnetic contactor in the upstream of the main power input so that
the power can be shut off at any time.
The main power (L1, L2 and L3) and control power (L1C and L2C) are separated internally. Be
sure to supply power to both of them. The following results indicate the correct state.
(1) The charge LED lights up in red.
(2) If the servo amplifier is in the factory shipment state, the keypad
shows the following.
~ -PSoF
 If the charge LED fails to light up
Appropriate voltage (200 [V] or 100 [V]) is not supplied to the main power terminals (L1, L2 and
L3). Check the source voltage.
Furthermore, if using a three-phase 400 V power supply, supply power after first dropping the
voltage to 200 V with a transformer (the servo amplifier will suffer damage with 400 V.)
