6.3.1 Minimum Wiring
1 Wire 200 VAC to terminals r and t of connector CNA of the Servo Amplifier
(hereinafter referred to "amplifier").
2 Wire 200 VAC to terminals R, S and T of amplifier connector CNA.
Ground the PE (protective earth ) terminal of the amplifier.
3 Wire the motor power lines to the U, V and W terminals as well as to the PE ( ) terminals of the
amplifier connector CNB. (For amplifiers having 15 A or 30 A capacity, connect an external
regenerative resistor between the P and Y (or COM) terminals of the connector CND.)
4 Wire the encoder cable to amplifier connector CN2.
5 Connect the remote operator to the amplifier connector OP.
6 When a brake is fitted with the motor, apply a specified voltage to the brake cable and release the
brake.
The parameter setting at the first power ON is assumed to be a standard setting.
In taking a runaway into consideration, be sure to fasten the motor to a fixing table or the
like, and also do not apply any load to its shaft side.
Wire the power supply so that it can be immediately cut off in case of an emergency.
