3. LOAD SIDE ENCODER
3.3 ABZ-phase Differential Output Encoder
This section describes the connection of the ABZ-phase differential output encoder. Prepare the MR-J3CN2
connector set for the encoder cable and produce it according to the wiring diagram in (3) of this section.
(1) ABZ-phase differential output encoder specifications
Each signal of the A-, B- and Z-phase of the 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 encoder without the Z phase cannot make a home position return.
