Applying Power to the Drive

Users please observe the following steps when applying power supply to the servo drive.
1. Please check and confirm the wiring connection between the drive and motor is correct.
1) Terminal U, V, W and FG (frame ground) must connect to Red, White, Black and Green cables
separately (U: Red, V: White, W: Black, FG: Green). If not connect to the specified cable and
terminal, then the drive cannot control motor. The motor grounding lead, FG must connect to
grounding terminal. For more information of cables, please refer to section 3.1.
2) Ensure to connect encoder cable to CN2 connector correctly. If users only desire to execute JOG
operation, it is not necessary to make any connection to CN1 and CN3 connector. For more
information of the connection of CN2 connector, please refer to Section 3.1 and 3.4.
Do not connect the AC input power (R, S, T) to the (U, V, W) output terminals. This will damage the AC servo
drive.

2. Main circuit wiring

Connect power to the AC servo. For three-phase input power connection and single-phase input power
connection, please refer to Section 3.1.3.

3. Turn the Power On

The servo power is main circuit power (R, S, T). When the power is on, the AC servo drive will start many
items of self-test. After the test, if
result is normal. If there is any text or value displayed on the display, please refer to parameter P0-01
(Drive Fault Code) to know the fault message and refer to Chapter 10 (Troubleshooting) to clear or
remove the fault.
1) When display shows:

Over voltage:

The main circuit voltage has exceeded its maximum allowable value or input power is error (Incorrect
power input).
Corrective Actions:
Use voltmeter to check whether the input voltage falls within the rated input voltage.
Use voltmeter to check whether the input voltage is within the specified limit.
