I/F circuit
PO1 P.3-35
• Feeds out the divided encoder signal or feedback scale signal (A, B, Z-phase) in differential.
(equivalent to RS422)
• Ground for line driver of output circuit is connected to signal ground (GND) and is not insulated.
• Max. output frequency is 4 Mpulse/s (after quadrupled)
• Can be used as position compare output, by setting bits 0 to 2 of Pr4.47 “Pulse output
select” to 1.

• Open collector output of Z-phase signal
• The emitter side of the transistor of the output circuit is connected to the signal ground (GND)
and is not insulated.
• When using the CZ signal, isolate it from external noise.
• Note that the logic of Z phase open collector output (CZ) is a reversal of the line driver
output (OZ) logic.
