connector is attached only on MR-J4-_B_-RJ.
Note 1. This is for MR-J4-_B-RJ servo amplifier. MR-J4-_B servo
amplifier does not have CN2L connector.
2. "External encoder" is a term for linear encoder used in the linear
servo system, load-side encoder used in the fully closed loop
system, and scale measurement encoder used with the scale
measurement function in this manual.
