Instructions of Digital Input/output Terminals
Digital input & output signals cables should be as short as possible, shielded, and their shielded layers
should be properly grounded close to the side of drive. The cables should not exceed 20m. When
active drive is selected, take necessary filtering measures against power crosstalk, for which dry
contact control is recommended.
Control cables shall be kept no less than 20cm away from main circuit and strong current lines (e.g.
power lines, motor lines, relay lines and contactor lines) and should not be arranged in parallel with
strong current lines. In case it is inevitable to intersect strong current line, vertical wiring is
recommended to avoid drive faults as a result of noise. Operating instructions for switching value input

ATTENTION:
When external power supply is used, the jumper b24V and PLC must be removed.
Otherwise, it may result in equipment damage
The voltage range of external power supply should be DC20
～
30V. Otherwise, normal operation
could not be assured and/or result in equipment damage.
