Introduction
(1) Visual wiring check
Before switching on the main circuit and control circuit power supplies, check the following items.
Power supply system wiring
The power supplied to the power input terminals (L1, L2, +24V, 0V) of the servo amplifier should satisfy
the defined specifications. (Refer to section 1.3.)
Connection of servo amplifier and servo motor
The servo motor power supply terminals (U, V, W) of the servo amplifier should match in phase with the
power input terminals (U, V, W) of the servo motor.

When regenerative option is used
The built-in regenerative resistor and its wirings should be removed from the servo amplifier.
The regenerative option should be connected to P and C terminals.
A twisted cable should be used. (Refer to section 11.2 (4).)
I/O signal wiring
The power supplied to CN1 connector (DICOM and DOCOM) of the servo amplifier should satisfy the
defined specifications. (Refer to section 1.3.)
SD and DOCOM of CN1 connector should not be shorted.
