Function and Operation

Connect an MR-J4A, MR-J3A, MR-J2(S)A, or MR-HA servo amplifier (with absolute position
detection function) manufactured by Mitsubishi to your system, and use this instruction to read out the
absolute position (ABS) data. The data will be converted into a pulse value before being read out.
Command

1) For
servo amplifier. Number of occupied points: 3 (
is the "send data ready" signal.)
2) For
signal to the servo amplifier. Be sure to use transistor outputs for the PLC outputs.
Number of occupied points: 3 (
