1. LINEAR ENCODER
1 - 26
1.3.2 LIC 4193M/LIC 4195M/LIC 4197M/LIC 4199M (absolute type)
POINT
These linear encoders have two-wire type and four-wire type. When using a
four-wire type linear encoder, change the parameter to select the four-wire type.
For changing parameters, refer to each servo amplifier instruction manual.
When using a linear encoder of four-wire type with fully closed loop control, use
an MR-J4-(DU)_A_-RJ/MR-J4-(DU)_B_-RJ.
When using a linear encoder of four-wire type with scale measurement function,
use an MR-J4-(DU)_B_-RJ.

Note 1. The connection to CN2C is for the MR-J4 3-axis servo amplifier. MR-J4 2-axis servo amplifier does not
have CN2C.
2. It should be prepared by the customer.
3. For connectors for thermistor signals, change how to connect depending on the customer's system.
