Note 1. The MR-J4THCBL03M branch cable is necessary.
2. The MR-J4FCCBL03M branch cable is necessary.
3. When the communication method of the servo motor encoder is four-wire type, MR-J4-_A4 and MR-J4-_B4 cannot be used.
Use an MR-J4-_A4-RJ or MR-J4-_B4-RJ.
4. Supported by servo amplifiers with software version A8 or above.
5. Connect a thermistor to CN2.
