13. OPTIONS AND AUXILIARY EQUIPMENT

(2) Encoder cable

CAUTION

If you have fabricated the encoder cable, connect it correctly.

Otherwise, misoperation or explosion may occur.

POINT

The encoder cable is not oil resistant.
Refer to Section 12.4 for the flexing life of the encoder cable.
When the encoder cable is used, the sum of the resistance values of the
cable used for P5 and the cable used for LG should be within 2.4 .
When soldering the wire to the connector pin, insulate and protect the
connection portion using heat-shrinkable tubing.

Generally use the encoder cable available as our options. If the required length is not found in the
options, fabricate the cable on the customer side.

(a) MR-JCCBL M-L MR-JCCBL M-H

These encoder cables are used with the HC-KFS HC-MFS HC-UFS3000r/min series servo
motors.
