Pay special attention to the followings when wiring:
1. When the power is cut off, do not touch R, S, T and U, V, W since the capacitance inside
the servo drive still contains huge amount of electric charge. Wait until the charging light is
off.
2. Separate R, S, T and U, V, W from the other wires. The interval should be at least 30 cm
(11.8 inches).
3. If the wire of CN2 is not long enough, please use shielded twisted-pair cable which cannot
exceed 20 meters (65.62 inches). If it exceeds 20 meters, please choose the bigger wire
diameter of signal cable to ensure it will not cause signal fading.
4. When selecting the wire rod, please refer to Section 3.1.6.
