Pay special attention to the following when wiring:
1. When the power is off, do not touch R, S, T and U, V, W, and P , D, C,
built-in capacitor of the servo drive can still contain a dangerously large amount of electric
charge. Wait until the "CHARGE" indicator is off.
2. Separate the RST power cable and the UVW power cable from other cables. The
separation should be at least 30 cm (11.8 inches).
3. For the encoder cable for CN2, use a metal braided shielded twisted-pair cable that
conforms to the UL 2464 standard.
4. When using RS-485, CANopen, DMCNET, EtherCAT, or PROFINET, use the shielded
twisted-pair communication cable to ensure the communication quality.
5. When selecting the wires, refer to Section 3.1.6.
6. Do not use any external capacitors, or it may damage the servo drive.
