■External encoder connector
The following table shows the external encoder communication methods connectable with MR-J5W2-_G-N1 and MR-J5W3-
_G-N1 servo amplifiers.
Operation mode
Linear servo system
Fully closed loop system
Scale measurement function
*1 The MR-J4THCBL03M branch cable is required.
*2 The MR-J4FCCBL03M branch cable is required.
*3 If the external encoder communication method is the four-wire type, MR-J5W2-_G-N1 cannot be used. In that case, use MR-J5-_G-
RJN1.
