Pin No.24:
• 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 4Mpps (after quadrupled)

No.
CZ
Symbol
• 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.
Note
• When the output source is the encoder
• If the encoder resolution ×
with A-phase. In other case, the Z-phase width will be equal to the encoder resolution, and
will not synchronize with A-phase because of narrower width than that of A-phase.

• In case of the 5-wire, 20-bit incremental encoder, the signal sequence might not follow the
above fig. until the first Z-phase is fed out. When you use the pulse output as the control
signal, rotate the motor one revolution or more to make sure that the Z-phase is fed out at
least once before using.
