4.1.2 Wiring Introduction
Wiring Notes:

Cable length, command cable within 3M, encoder length within 20m.

Check whether the power supply and wiring of L1, L2 and L3 are correct. If only 220VAC
drives are supported, do not connect to 380VAC power supply.

The phase sequence of the motor output u, V and W terminals must correspond to the
corresponding terminals of the driver one by one. If the motor is connected incorrectly, the
motor may not rotate or run fast. The motor cannot be reversed by changing the three-phase
terminals, which is different from asynchronous motor.

Because the servo motor flows through the high-frequency switching current, the leakage
current is relatively large. The motor grounding terminal must be connected with the servo
driver grounding terminal PE and well grounded.

For the relay installed in the output signal, the direction of the diode for absorption shall be
connected correctly, otherwise it will cause failure and fail to output the signal.

To prevent the wrong action caused by noise, please add insulation transformer, noise filter
and other devices to the power supply.

Please wire the power line (strong current circuit of motor line, power line, etc.) more than
30cm away from the signal line, and do not place it in the same wiring pipe.

Please install a non fusible circuit breaker to cut off the external power supply in time in
case of driver failure.

Because there is a large capacity electrolytic capacitor inside the servo driver, even if the
power supply is cut off, there is still high voltage in the internal circuit. After cutting off the
power supply, wait at least 5 minutes to contact the driver and motor.
