Notices regarding the use of inverter drives
- Motor rating
The capacity range of the "Shrink wrapping machines" is small.
Sometimes, there is a 100V motor rating.
In this case, please change the motor from 100V rating to 3 phase, 200V rating.
(The inverter is designed for 3 phase 200V or 400V motor.)
|
If you have only a single phase 100V power supply,
please select the VF-nC3 series that has a line-up for single phase 100V input / 3 phase 200V output.
VFNC3S-1001P (0.1kW)
VFNC3S-1002P (0.2kW)
VFNC3S-1004P (0.4kW)
VFNC3S-1007P (0.75kW)

- Motor maximum speed
The motor maximum speed depends on the motor specifications.
Please confirm the specifications of the manufacturer of your motor.

- 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.)
