Note5) The max. input pulse frequency and the min. input pulse width
should be used at the following setting.
䊶㩷Max. input pulse frequency (1/T) : 10 kHz or less
䊶㩷Overlap (t2) : 25㱘s or more
Note6) Confirm the rotation direction before making the connection of
the output signal (phase A and phase B) of the encoder.

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.
Note4) Control the cable wiring length of the encoder within 5m or less.
7. The total length of the communication cable must be 500m or less.
