Manufacturer setting connector (CN7)
This connector is attached on the MR-J4-_A-RJ servo
amplifier, but not for use. The MR-J4-_A servo amplifier
does not have this connector.
Note 1. This is for the MR-J4-_A-RJ servo amplifier. The MR-J4-_A servo
amplifier does not have the CN2L connector.
2. "External encoder" is a term for linear encoder used in the linear servo
system and load-side encoder used in the fully closed loop system in this
manual.
