2.9.1 Cable selection for I/O signal port CN1 and encoder feedback
port CN2
I/O signal cable
To ensure I/O signal to not be affected by electromagnetic interference, a
shielded
twisted pair cable
is recommended for this application.
Diameter
: Recommended to use stranded and shielded cable. For CN1
, ≥0.14mm
2
,
CN2≥0.25mm
2
, shielding layer needs to be grounded.
Length
: Cable length should be as short as possible. No more than 3m for CN1 and 20m
for CN2.
Placement:
Place the cable away from power cables.
Install a surge suppressor in feedback circuit; flyback diode inversely connected in
parallel in DC coil and capacitor connected in parallel in AC coil.
I/O signal included DI, DO and relay output signal
Please keep 30cm away from main power supply cable or motor power cable to avoid
electromagnetic interference.
