When not using a
branch cable
5) Connector set MR-J3CN2
(Refer to (2) (b) of this
section.)
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. When mounting ST741A, ST742A, ST743A, ST744A or ST748A, a personal computer (with RS-232C port) for the signal
adjustment and confirmation, and a software and conversion unit for signal adjustment are required. For details, contact
Mitutoyo.
4. For connectors for thermistor signals, change how to connect depending on the customer's system.
