Wiring Precautions
Caution

Be sure to use AC 200-230 V for the input power of the servo drive.

Be sure to connect the servo drive ground terminal.

Do not connect commercial power directly to the servo motor.

Do not connect commercial power directly to the U, V, W output terminal of the servo drive.

Directly connect U, V, W output terminals of the servo drive and U, V, W input terminals of the
servo motor, but do not install a magnetic contactor between the wiring.

Be sure to use a pressurized terminal with an insulation tube when you connect the power
terminal for the servo drive.

When wiring, be sure to separate the U, V, and W cables for the servo motor power and
encoder cable.

Be sure to use robotic cable if the motor requires movement.

Before you perform power line wiring, turn off the input power of the servo drive, and then wait
until the charge lamp goes off completely.

Be sure to use shielded twisted-pair wire for the pulse command signal (PF+, PF-, PR+, PR-),
speed command signal (SPDCOM), and torque command signal (TRQCOM).

Precautions for Initial Operation
Caution

Check the input voltage (AC 200-230 V) and power unit wiring before you turn on the power.

The servo must be in the OFF mode when you turn on the power.

Before you turn on the power, check the motor's ID and the encoder pulse for L7
□
A
□□□
A.

Set the motor ID ([P0-00]) and the encoder pulse ([P0-02]) for L7
□
A
□□□
A first after you
turn on the power.

After you complete the above settings, set the drive mode for the servo drive that is connected
to the upper level controller to [P0-03].

Refer to Chapter 1.2 "System Configuration" to perform CN1 wiring for the servo drive
according to each drive mode.

You can check the ON/OFF state for each input terminal of CN1 at [St-14].

Precautions for Handling and Operation
Caution

Check and adjust each parameter before operation.

Do not touch the rotating unit of the motor during operation.

Do not touch the heat sink during operation.

Be sure to attach or remove the CN1 and CN2 connectors when the power is off.

Extreme change of parameters may cause system instability.
