When not using a
branch cable
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.
POINT
When the absolute position detection system is configured, the absolute position
battery is not required.
POINT
This linear encoder is of four-wire type. When using this linear encoder, change
the parameter to select the four-wire type. For changing parameters, refer to
each servo amplifier instruction manual.
This linear encoder cannot be used in the fully closed loop system.
