Pay special attention to the following when wiring:
1. When the power is off, do not touch R, S, T, U, V, W, P , D, C, and
capacitance inside the servo drive can still contain a dangerously large amount of electric
charge. Wait until the charging light is off.
2. Separate R, S, T and U, V, W from other wires. The separation should be at least 30 cm
(11.8 inches).
3. When using RS-485, use the shielded twisted-pair cable to ensure the communication quality.
4. When selecting the wires, refer to Section 3.1.6.
5. Do not use any external capacitor, or it might damage the servo drive.
