Preface
Thank you for purchasing the industrial inverter "TOSVERT VF-A7".
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)
Add-on cassettes compatible with sensor vector control
(Speed feedback, torque control and positioning control, etc... )
Sensor vector control-compatible board
(Speed feedback, torque control)
Extension panel Parameter writer
Other optional devices common to all models
Control power supply unit
Heat-sink attachment
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.
