A/B/Z-phase differential output method
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 and A/B/Z-phase differential output
method, MR-J4W2-_B cannot be used. Use an MR-J4-_B-RJ.
4. This is used with servo amplifiers with software version A3 or later.
5. This is used with servo amplifiers with software version A8 or later.
6. The synchronous encoder Q171ENC-W8 cannot be used due to the four-wire type.
