Merits of inverter drives

Winders with inverters have the following merits:

- Stable speed control for high textile quality
Inverters can provide stable motor control.
Therefore winders can avoid uneven winding.
If you use the vector control with sensor, you can control a motor with an accuracy of 1:1000.

- Electromagnetic noise reduction by built-in noise filter
Many of TOSHIBA's inverters have buil-in noise filters.
Therefore, you can reduce electromagnetic noise without optional devices.

VF-AS1 series:
200V input class
  Models up to 7.5kW have built-in EMC noise filters.
  Models over 11kW have capacitive noise filters.
400V input class
  All of our products have built-in EMC noise filters.

VF-S15 series:
200V input class
  All of our products have capacitive noise filters.
400V input class
  All of our products have built-in EMC noise filters.

- Multiple control through original communication protocol
In almost all cases, textile machines have many winders which have to work together smoothly.
Toshiba inverters have an original communication method.
This communication method can support proportional control of all inverters by single frequency reference.
