APPENDIX 1.2 Serial absolute synchronous encoder cable
Generally use the Serial absolute synchronous encoder cables available as our
options. If the required length is not found in our options, fabricate the cable on the
customer side.
(1) Selection
The following table indicates the Serial absolute synchronous encoder cables
used with the servomotors.
Make selection according to your operating conditions. Connector sets(MRJ2CNS) are also available for your fabrication.
