4.6.6 Wiring procedure for main circuit terminal CN6
1. Connect the input power cable to the drive power input terminals R, S, and T. Connect
the ground conductor of the input power cable to any of drive ground screws and fasten
the screw properly to ensure a smooth connection.
2. Connect the motor three-phase input terminals W, V and U to the motor connection
terminals W, V and U respectively, and fasten the screws properly to ensure a smooth
connection. Connect the motor ground terminal to any of the drive ground screws (screen
printed with PE). Connect the motor temperature measuring resistor terminals to the
drive terminals T1 and T2. Connect the motor resolver connection terminal to the drive
connector CN2, and fasten the screws.
3. Connect the two wiring terminals of braking resistor to the drive terminals U+ and PB
respectively, and fasten the screws properly to ensure a smooth connection.
