You can set up the pulse counts to be fed out from the pulse output (X5 0A+ : Pin-
21, 0A- : Pin-22, 0B+ : Pin-48, 0B- : Pin-49).
• Pr45=<0> (Default)
You can set up the output pulse counts per one motor revolution for each OA
and OB with the Pr44 setup. Therefore the pulse output resolution after
quadruple can be obtained from the formula below.
• Pr45 ≠ 0 :
The pulse output resolution per one revolution can be divided by any ration
according to the formula below.
<Cautions>
• The encoder resolution is 131072 [P/r] for the 17-bit absolute encoder, and
10000 [P/r] for the 5-wire 2500P/r incremental encoder.
• The pulse output resolution per one revolution cannot be greater than the
encoder resolution.
(In the above setup, the pulse output resolution equals to the encoder resolution.)
• Z-phase is fed out once per one revolution of the motor.
When the pulse output resolution obtained from the above formula is multiple of 4,
Z-phase synchronizes with A-phase. In other case, the Z-phase width equals to
output with the encoder resolution, and becomes narrower than A-phase, hence
does not synchronize with A-phase.

Valid
Invalid
Command pulse input will be inhibited by opening the connection of INH input to
COM–. When you do not use INH input, set up Pr43 to 1 so that you may not
need to connect INH (CN I/F Pin-33) and COM– (Pin-41) outside of the driver.
