Pulse output mode
Set the pulse output mode to match the servo amplifier being used.
(The QD75 outputs the pulse in negative logic at default.)
(1) PLS/SIGN mode
Forward run and reverse run are controlled with the ON/OFF of the direction sign
(SIGN).
• The motor will run in the forward direction when the direction sign is LOW.
• The motor will run in the reverse direction when the direction sign is HIGH.
Forward run
Move in + direction
Reverse run
Move in - direction

(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.

(3) A phase/B phase mode (Common for multiple of 4 and multiple of 1)
Forward run and reverse run are controlled with the phase difference of the A
phase (A
φ
) and B phase (B
φ
).
• When the B phase is 90° behind the A phase, the motor will run in the forward
direction.
• When the B phase is 90° ahead of the A phase, the motor will run in the reverse
direction.

(2) For multiple of 1 setting
