3.3 Operation Check
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.
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 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 display on the amplifier
shows the following.
If the charge LED does not light up
200 V is not supplied to the main power terminals (L1, L2 and L3). Check the source voltage.
Operation does not start with single-phase 100 V power supply. In case of three-phase 400 V, use
a transformer to drop to 200 V to supply. (400 V will cause the servo amplifier to be broken.)
If the display does not light up
200 V is not supplied to the main power terminals (L1, L2 and L3). Check the source voltage.
Operation does not start with signal-phase 100 V power supply. In case of three-phase 400 V, use
a transformer to drop to 200 V to supply. (400 V will damage the servo amplifier.)
