EMC Istallations
The Inverter generates very strong interference. Although EMC measures are taken, the
interference may still exist due to improper cabling or grounding during use. When the Inverter
interferes with other devices, adopt the following solutions.

•
Connect the motor housing to the PE of the Inverter.
•
Connect the PE of the Inverter to the PE of the mains power supply.
•
Add a safety capacitor to the power input cable.
•
Add magnetic rings to the input drive cable.
Inverter interference
•
Connect the motor housing to the PE of the Inverter.
•
Connect the PE of the Inverter 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 safety capacitor to the interfered signal port or wind the signal cable
with magnetic rings.
•
Connect the equipment to the common ground.
Communication
•
Connect the motor housing to the PE of the Inverter.
•
Connect the PE of the Inverter to the PE of the mains voltage.
•
Add a safety capacitor to the power input cable and wind the cable with
magnetic rings.
interference
•
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.
