Safety Environmental Compatibility |
Ambient temperature 60 degreeC |
The VF-AS1 can be used at a rating up to an ambient
temperature of 50 degreeC and in environments up to 60 degreeCC at a
derating current. |
Eco Design |
88% of materials used on the VF-AS1 are recyclable, which
design more than meets of the European WEEE (Waste
Electrical and Electronic Equipment) Directive of 70%. |
Various Drive Performance |
Permanent Magnet Motor (PM) Drive |
The PM is driven efficiently by a TOSHIBA oriented control
argorithm to achieve savings in energy and space. |
New DC Braking |
A newly developed DC braking function allows the stop time
to a quarter of that on conventional models. |
A Further Enhanced of Functions |
Multi-PID Control |
As well as process-type PID control (e.g. temperature, pressure,
flow rate), the VF-AS1 incorporates speed-type PID control that
is compatible with speed feedback, for example, in follow-up
operation or winding, for line compatibility with line control. |
Traverse
Power interruption synchronized control |
Two extra controls are achieved, traverse control during
rewinding that is mandatory on fabric machinery, and
power interruption synchronized control for preventing
thread breakage when a power interruption occurs. |
Drooping
Speed gain switching
Zero speed lock
Dwell |
Drooping distributes the load of 2-shaft drive on conveyance
machinery, for example. Speed gain switching enables
adaptation to changes in inertia during operation. Zero speed
is hold when the inverter is stopped. And dwell controls
acceleration/deceleration, for example, when conveying
heavy loads. |
