Judging The Pulse Signals Of Phase A And B, And Forward/Reverse Directions - Panasonic AAD03011 Instruction Manual

Note4) Control the cable wiring length of the encoder within 5m or less.
Note5) The max. input pulse frequency and the min. input pulse width
should be used at the following setting.
Max. input pulse frequency (1/T) : 10 kHz or less
Phase difference (t1): 25 s or more
Overlap (t2) : 25 s or more
Phase A
Phase B
Note6) Confirm the rotation direction before making the connection of
the output signal (phase A and phase B) of the encoder.
[Judging the pulse signals of phase A and B, and forward/
reverse directions]
Open operation in
forward direction
(Count addition)
Close operation in
reverse direction
(Count subtraction)
6. For the communication cable, use a double-core cable(VCTF) or
twisted pair cable ( with shield). Keep the cable away from power
lines and strong electric circuits.
7. The total length of the communication cable must be 500m or less.
