IS810N-INT Series Servo System User Manual (Brief) Chapter 4 Wiring
For the power supply and the main circuit connection, make sure that the main circuit power 
supply is cut off and the servo changes from the ON state to the OFF state after the alarm 
signal is detected.
Connect the U, V, and W cables of the servo drive to the U, V, and W terminals of the motor 
directly. Do not connect an electromagnetic contactor. Failure to comply may result in 
abnormalities and faults.
