Introduction
Thank you for purchasing the Toshiba High-Performance Inverter "TOSVERT VF-AS".
The "VF-AS" inverter has many various functions built in for use with a 3-phase induction motor. All
Operations of this unit are done via the easy-to-use keyboard-type operation panel. A blind function
(Refer to page SS) that displays only those functions required for operation, and an edit function (Refer to
page 34) that automatically collects parameters that differ from their default settings are used to make
basic operation and setting easier. Advanced control technology features (sensorless vector control,
feedback control, current limit, retry, and stall prevention functions) are built in, so that the inverter will not
trip easily, and will provide unparalleled reliabilty.
Please read this manual thoroughly before use to properly understand the correct use of the outstanding
functions of the "VF-AS".
This manual should be stored by the user of the "VF-AS" for reference during maintenance and inspection.
