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, L
1C
,
L
2C
, 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, L
1C
, L
2C
, 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 (CN2) or the cable for position feedback signal connector (CN5)
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
