(4) Pulse regeneration function
The information on the amount of movement can be sent to the host controller in the
form of A- and B-phase pulses from the servo driver. When the output source is the
encoder, Z-phase signal is output once per motor revolution; or if the feedback scale,
the signal is output at absolute zero position. The output resolution, B-phase logic and
output source (encoder or feedback scale) can be set with parameters.

Unit
You can set up the output pulse counts per
P/r one motor revolution for each OA and OB
with the Pr0.11 setup.
You can set up the B-phase logic and
the output source of the pulse output.
With this parameter, you can reverse the
0 to 3 —
phase relation between the A-phase pulse
and the B-phase pulse by reversing the
B-phase logic.
For application where the number of
pulses per revolution is not an integer,
this parameter can be set to a value other
—
than 0, and the dividing ratio can be set by
setting numerator of division to Pr0.11 and
denominator of division to Pr5.03.

Full-closed control using serial absolute
feedback scale. When outputting pulses by

pulse
the output, set the Z phase output interval
in units of A phase output pulses of the
feedback scale (before multiplied by 4).
Select the pulse regeneration method of A,
0 to 1 —
B and Z parallel feedback scale.
You can set up the clearing conditions of the
0 to 4
counter clear input signal.
