Pay special attention to the followings when wiring:
1. When the power is cutoff, 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 encoder CN2 or CN5 connecter 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. As
for the encoder wiring specification of 20-meter-long cable, please use AWG26 of wire size
and metal braided shield twisted-pair cable which complies with the standard of UL 2464.
4. When using CANopen, please use the standard shielded twisted-pair cables to ensure the
communication quality.
5. When selecting the wire rod, please refer to Section 3.1.6.
6. Do not install the plug-in capacitance in servo drive. It might burn out the soft-start resistance
and danger will occur.
