2) 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 as far as possible more than 30 cm interval.
3) If the encoder cable is need to lengthen, please use a twisted-shield signal wire with grounding
conductor. The wire length should be 20m or less. For lengths greater than 20m, the wire gauge
should be doubled in order to lessen any signal attenuation.

3-1-4 Power supply connections for control circuit
Servo drives wiring connections include single phase connection and three phase connection.
Single phase connection can only fit for 1KW following models. In below drawing, 1MC/x is
electromagnetic contactor coil, 1MC/ a is self-holding power, 1MC is main circuit interface.
