Description Use the analog input terminal
Weak analog voltage signals are easy to suffer external interference, and therefore the shielded
cable must be used and the cable length must be less than 20 m, as shown in following figure. When

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
