■A phase/B phase mode
Forward run and reverse run are controlled with the phase difference of the A phase (Aφ) and B phase (Bφ). 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.
• For multiple of 1 setting
Positive logic
Forward run
Command 1 pulse output
A phase
(AΦ)
B phase
(BΦ)
The B phase lags
the A phase by 90°.
Example) When the command 1 pulse output is set to 1pulse/s, the pulse rises and falls four times per second.
• For multiple of 4 setting
Positive logic
Forward run
Command 1 pulse output
A phase
(AΦ)
B phase
(BΦ)
The B phase lags
the A phase by 90°.
Example) When the command 1 pulse output is set to 1 pulse/s, the pulse rises and falls one time per second.
