5 DATA USED FOR POSITIONING CONTROL
PULSE F
PULSE R
Forward run
Forward run
Forward rotation when one
command pulse is output
A phase
(A )
B phase
(B )
When B phase is
90 behind A phase
Forward run
Forward rotation when one
command pulse is output
A phase
(A )
B phase
(B )
When B phase is
90 behind A phase
(2) CW/CCW mode
During forward run, the forward run feed pulse (PULSE F) will be output.
During reverse run, the reverse run feed pulse (PULSE R) will be output.
Positive logic
Reverse run
(3) A phase/B phase mode
Forward run and reverse run are controlled with the phase difference of the A
phase (A) and B phase (B).
When the B phase is 90 ° behind the A phase, the motor will forward run.

When the B phase is 90 ° ahead of the A phase, the motor will reverse run.

The D75P2 defines a waveform having four edges (rising/falling) in one command
pulse as "multiple of 4", and one having a single edge (rising/falling) in one
command pulse as "multiple of 1".
(a) For multiple of 1 setting
Positive logic
Reverse run
Forward rotation when one
command pulse is output
When B phase is
90 ahead A phase
Example) When one command pulse is output at 1 pulse/s, rising and falling
occur once per second.
(b) For multiple of 4 setting
Positive logic
Reverse run
Forward rotation when one
command pulse is output
When B phase is
90 ahead A phase
Example) When one command pulse is output at 1 pulse/s, rising and falling
occur four times per second.
