4 STARTUP
4.1 Switching power on for the first time
6.
Test operation of the servo motor alone by commands
For the test operation with the servo motor disconnected from the machine and operated at the speed as low as possible, give
commands to the servo amplifier and check whether the servo motor rotates correctly.
7.
Test operation with the servo motor and machine connected
After connecting the servo motor with the machine, check machine motions with sending operation commands from the
controller.
8.
Gain adjustment
Make gain adjustment to optimize the machine motions.

Actual operation
10.
Stop
Stop giving commands and stop operation.
Wiring check
Before switching on the main circuit and control circuit power supplies, check the following items.
Power supply system
• The power supplied to the power input terminals (L1/L2/L3/L11/L21) of the servo amplifier should satisfy the defined
specifications.

Page 30 FUNCTIONS AND CONFIGURATION
• When the power factor improving DC reactor is not used, between P3 and P4 should be connected.
*1 The 100 V class servo amplifiers do not have P3 and P4.
Connection of servo amplifier and servo motor
• The servo amplifier power output (U/V/W) should match in phase with the servo motor power input terminals (U/V/W).
• The power supplied to the servo amplifier should not be connected to the servo motor power terminals (U/V/W). Doing so
will fail the servo amplifier and servo motor.
• The grounding terminal of the servo motor is connected to the PE terminal of the servo amplifier.
• The CN2 connector of the servo amplifier should be connected to the encoder of the servo motor securely using the
encoder cable.
