Notices regarding the use of inverter drives
- Motor rating
The capacity range of the "Slicers" 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.)
- Deceleration time for cutter
When you stop the cutter quickly, you may need to install a braking resistor.
In this case, please select VF-S15 or VF-AS1 series.
In VF-nC3, you have to prepare also a braking module(BRMD0015Z)
- Maximum motor speed
The maximum motor speed depends on the motor specifications.
Please confirm the specifications of the manufacturer of your motor.
The specifications of TOSHIBA motors are as follows:
- Avoiding "Mist" and "Cutting rubbish"
Usually, slicers 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.
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.)
