2. Noise
There is noise that enters from outside and causes the inverter to malfunction and
that which is generated from the inverter and causes the peripheral equipment to
malfunction. The inverter is designed so that it is not easily affected by noise. but
as it is an electronic device which handles weak signals. the following general
countermeasures will be required.
+General countermeasures
• Avoid laying the inverter's power cables (input/output) in parallel with the
signal wires and avoid bundling the power cables and signal wires.
• Use twisted pair shield wires for the connection wires with the sensor and for
the
control signal wires. Connect the sheath of the shield wire to terminal SO.
• Use
one-point grounding for the inverter and motor. etc.
