Wiring Notes

Please observe the following wiring notes while performing wiring and touching any electrical
connections on the servo drive or servo motor.
1. Ensure to check if the power supply and wiring of the "power" terminals (R, S, T, U, V, & W) is
correct.
2. Please use shielded twisted-pair cables for wiring to prevent voltage coupling and eliminate
electrical noise and interference.
3. As a residual hazardous voltage may remain inside the drive, please do not immediately touch
any of the "power" terminals (R, S, T, U, V, & W) and/or the cables connected to them after the
power has been turned off and the charge LED is lit. (Please refer to the Safety Precautions on
page ii).
4. The cables connected to R, S, T and U, V, W terminals should be placed in separate conduits
from the encoder or other signal cables. Separate them by at least 30cm (11.8 inches).
5. If the encoder cable is too short, please use a twisted-shield signal wire with grounding
conductor. The wire length should be 20m (65.62ft.) or less. For lengths greater than 20m
(65.62ft.), the wire gauge should be doubled in order to lessen any signal attenuation.
6. As for motor cable selection, please use the 600V PTFE wire and the wire length should be less
than 98.4ft. (30m). If the wiring distance is longer than 30m (98.4ft.), please choose the
adequate wire size according to the voltage.
7. The shield of shielded twisted-pair cables should be connected to the SHIELD end (terminal
marked
8. For the connectors and cables specifications, please refer to section 3.1.6 for details.
