(17) Charge lamp
When the main circuit is charged, this will light up. While this lamp is lit, do not reconnect the cables.
*1*2
(18) External encoder connector (CN2L)
Used to connect the external encoder. Refer to the following for the compatible external encoders.
Page 18 Summary
(19) Optional unit connector 1 (CN7)
This connector is used for connection with an optional unit. This connector is attached only on MR-J4-
_GF_-RJ.
(20) Optional unit connector 2 (CN9)
This connector is used for connection with an optional unit. This connector is attached only on MR-J4-
_GF_-RJ.
*1 This is for MR-J4-_GF4-RJ servo amplifier. MR-J4-_GF4 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.
■MR-J4-350GF4(-RJ)
The diagram shows MR-J4-350GF4-RJ.
