Wiring check
Before switching on the power supply, check the following items.
Power supply system wiring
Power supply system wiring
• Check that the power supplied to the power input terminals (L1/L2/L3) of the servo amplifier satisfies the defined
specifications.
For the power supply specifications, refer to "Servo amplifier standard specifications" in the User's Manual (Introduction).
Connecting the servo amplifier to the servo motor
• Check that the phases (U/V/W) of the servo amplifier power outputs and the phases (U/V/W) of the servo motor power
inputs match with each other.
• Check that the power to be supplied to the servo amplifier is not connected to the power outputs (U/V/W) as doing so will
cause the servo amplifier and the servo motor to malfunction.
• Check that the grounding terminal of the servo motor is connected to the PE terminal of the servo amplifier.
• Check that the CN2 connector of the servo amplifier is securely connected to the encoder of the servo motor using the
encoder cable.
Using options or peripheral equipment
■
Regenerative option
• Check that the built-in regenerative resistor and wiring have been removed from the servo amplifier.
• Check that the lead wires of the built-in regenerative resistor connected to the P+ terminal and C terminal have been
removed.
• Check that the wire of the regenerative option is connected to terminal P+ and terminal C.
• Check that twisted wires have been used for connecting the regenerative option to the servo amplifier.
