 Notices regarding the use of inverter drives
- Avoiding 'Lint'
Usually, winders are used in a dusty environment.
If this is the case, you have to install the inverter in a cabinet, or please select the IP54 model of VFS11.
- Electromagnetic noise
The inverter is generating 'electromagnetic noise'.
If there are some high accuracy sensors or other sensitive equipment near the inverter drive,
the inverter's noise may cause some trouble or a malfunction.
Electromagnetic noise can be avoided by installing an external noise filter or
using a different wiring method.
- Harmonics
The inverter is generating 'harmonics'.
These harmonics sometimes cause a malfunction in other control equipment
that is connected to the same power source.
Harmonics can be avoided by installing an external 'reactor'.
To decrease 'harmonics', we recommend to install DC reactors in all our inverter models.
(NOTE: 100V input models require AC reactors.)
