Toshiba VF-A7 instruction manual Ⅱ． Preface, Features

Ⅱ． Preface

Thank you for purchasing the industrial inverter "TOSVERT VF-A7".

This inverter has a "Ver. 315"CPU or later.

Please refer to "10. Table of parameters" for the functions available for the inverter with a CPU in this version.

The CPU version will be frequently upgraded.

■Features

1. Noise filter incorporated

1)Every 200V or 400V model (200V 0.4～7.5KW and 400V 0.75～15kW models) has a built-in noise filter.

2)" VF-A7" complies with the European CE marking requirements. 3)" VF-A7" complies with the UL/cUL standard.

4)" VF-A7" saves space and does not require troublesome wiring.

2.Excellent torque control performance

1)200% torque even at a frequency of 0.5 Hz(with vector control) The speed control ratio is 1 :150.

2)Torque limit function

3.A wide range of applications from simple speed control to system control

1)Auto-tuning function

All you have to do make the " VF-A7" ready for start is to connect it to the motor and the power supply unit; the " VF-A7" does not require cumbersome parameter setting to start it.

2)High flexibility and system expendability

" VF-A7" has a number of functions, including torque control, sensor (or sensorless) vector control, drooping function, commercial power/inverter switching function and various communication functions, which allow the inverter to be used as part of a system.

3)Torque control

In addition to speed control by the frequency command, " VF-A7" is capable of speed control by the torque command, which is best suited to winding control.

4.Options that widen the range of application

･Extended terminal board

･Communication devices

(RS485, RS232C, TOSLINE-F10M/S20)
