Control cables shall be kept no less than 20cm aw ay from main circuit and strong current lines
(e.g. pow er lines, motor lines, relay lines and contactor lines) and should not be arranged in
parallel w ith strong current lines. In case it is inevitable to intersect strong current line, vertical
w iring is recommended to avoid drive faults as a result of noise.
Where analog input & output signals are severely interfered, the side of analog signal source
should be provided w ith filter capacitor or ferrite core.
3.9.4 Instructions of Digital Input/Output Terminals
Digital input & output signal 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 pow er crosstalk,
for w hich dry contact control is recommended.
