Charge lamp
When the main circuit is charged, this will light.
While this lamp is lit, do not reconnect the cables.
The lamp may light up when only the control circuit
is powered on. Before wiring or inspection, turn off
the main circuit power and the control circuit power,
and wait for 15 minutes or more until the charge
lamp turns off. Then, check the voltage between P+
and N- using the tester, etc.

Optional unit connector 1 (CN7)
This is for connecting the optional unit. This
connector is attached only on MR-J4-_B_-RJ.
(20)
Optional unit connector 2 (CN9)
This is for connecting the optional unit. This
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.
