Abz-Phase Differential Output Load Side Encoder - Mitsubishi Electric MELSERVO-J3 Series Instruction Manual

3. LOAD SIDE ENCODER

3.3 ABZ-phase differential output load side encoder

This section describes the connecti on of the ABZ-phase differential output load side encoder. Prepare the MR-
J3CN2 connector set for the load side encoder cable and produce it according to the wiring diagram in (3) in
this section.
(1) ABZ-phase differential output load side encoder specifications
Each signal of the A, B and Z-phase of the load side encoder is provided in the differential line driver output.
It cannot be provided in the collector output.
The phase differences of the A- and B-phase pulses and the pulse width of the Z-phase pulse need to be
200ns or more.
The load side encoder without the Z-phase cannot make a home position return.
