2.3 Servomotor
There are wiring of the following three units: the main body of the servomotor, brake (servomotor equipped
with a brake) and encoder.
CAUTION

Keep consistency in the phase order between the servomotor and servo amplifier.

Do not connect commercial power to the servomotor. Otherwise it may cause failure.
2.3.1 Brake Connector
Connector kit type: WSK-M02P-E (GYB,GYC,GYS type servomotor side ,0.75 kW or less)
The brake of the servomotor equipped with a brake is a non-exciting brake. To rotate the servo motor,
supply the power of 24 VDC to this connector and release the brake. There is no polarity in the brake
input circuit.
If the brake is left released, although the periphery of the brake becomes hot it is not a fault.
The brake terminal of GYH type 1.0 to 3.0 kW, GYG type, GYC type 1.0 to 2.0 kW and GYS type 1.0 to
5.0 kW is located inside the motor power connector.
The brake terminal of GYH type 4.0 to 7.0 kW is located inside the motor brake connector.
