Installation method of Yaskawa encoder and common alarm codes of driver

1. Remove the three screws at 1, 2, and 3

　　二. Screw in with an M6 screw

　　(2) Push out the encoder at the middle screw hole

　　 (can't pry out)

　　三. When the encoder and the steel sheet are installed,

　　Encoder yellow jack (1)

　　 and the small gap of the steel sheet (2) need to be in the opposite direction

　　4. The bayonet of the encoder must be aligned with the bayonet of the motor during installation

　　 Note that the direction of the yellow socket of the encoder is on the left hand side after installation

　　 (viewed from behind the motor)

　　■Mechanical aspects

　　 Real shaft type: Do not rigidly connect the encoder shaft and the user shaft, please use an elastic coupling.

　　 When installing, please pay attention to the allowable shaft load of the encoder.

　　Empty shaft type: Do not rigidly connect the encoder shaft and the user shaft, please use an elastic coupling plate.

　　 When installing, please pay attention to the allowable shaft load of the encoder.

　　■Electrical aspects

　　 Please do not wind the encoder output line and power line together or transmit in the same pipeline, nor should it be used near the switchboard. When wiring, please press

Wiring table or instruction manual, turn on after checking
