Interference Type Solution
Communication
interference
•
Connect the motor housing to the PE of the controller.
•
Connect the PE of the controller to the PE of the mains voltage.
•
Add a safety capacitor to the power input cable and wind the cable
with magnetic rings.
•
Add a matching resistor between the communication cable source
and the load side.
•
Add a common grounding cable besides the communication cable.
•
Use a shielded cable as the communication cable and connect the
cable shield to the common grounding point.
I/O interference
•
Enlarge the capacitance at the low-speed DI. A maximum of 0.11 uF
capacitance is suggested.
•
Enlarge the capacitance at the AI. A maximum of 0.22 uF is
suggested.
