8-2-9 Controller or AM Radio Receives Noise when
Inverter is Started
·
Noise derives from Inverter switching.
Take the following actions to prevent noise.
S
Lower the carrier frequency of the Inverter in n080.
The number of internal switching times is reduced, so noise can be reduced to
some extent.
S
Install an Input Noise Filter.
Install an Input Noise Filter on the power input area of the Inverter.
S
Install an Output Noise Filter.
Install an Output Noise Filter on the output area of the Inverter.
S
Use metal tubing.
Electric waves can be shielded by metal. Therefore, enclose the Inverter with a
metal tube.
8-2-10 Ground Fault Interrupter is Actuated when
Inverter is Started
·
Leakage current flows through the Inverter.
The Inverter performs internal switching. Therefore, a leakage current flows through
the Inverter. This leakage current may actuate the ground fault interrupter, shutting
the power OFF.
Use a ground fault interrupter with a high leakage-current detection value (sensitivity
amperage of 200 mA or more, operating time of 0.1 s or more) or one with high-fre-
quency countermeasures for Inverter use.
Reducing the carrier frequency value in n080 is also effective.
In addition, remember that a leakage current increases in proportion to the cable
length. Normally, approximately 5 mA of leakage current is generated for each meter
of cable.
