Wiring Notes
5. Installation
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, L1,
L2, 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, L1, L2, 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 chapter 2 "Before you begin - safety
information").
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) 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
) of the servo drive.
8. For the connectors and cables specifications.
