This panel is an 23-character x
8-line display, and can be used
for simple setup and monitoring
by s e l e c t i o n o f p a ra m e t e r s
using the jog dial. The display

(German, Italian, Spanish, and
Chinese will be available soon.)
Type: RKP004Z
* The photograph shows a screen
currently in development.
Our customers require a "display that is easily visible from
a long way away." In response to this need, we developed
this panel using 20 mm LEDs, the largest in its class in the
market, to ensure outstanding visibility.
It has also been designed to be
fitted into panels for use as an
extension panel or display.
In addition, it can be used as a
parameter copy and is capable of
storing parameters for up to three
models.
Type: RKP002Z
This I/O terminal block can be added on to enhance your
system for extra compatibility with a wide range of systems:
• Contact inputs (4) • Contact outputs (2) • Analog inputs (2)
• Analog outputs (2) • PTC input (1) • Relay output (1 circuit)
• Pulse train input (1)
Type: ETB003Z, ETB004Z
Main fieldbuses are supported to enable connection to a
host controller to achieve savings in space and centralized
control of systems.
• DeviceNet* 1 • PROFIBUS • CC-Link

The VF-AS1 can be used at a rating up to an ambient
temperature of 50°C and in environments up to 60°C at a
derating current.
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%.
The PM is driven efficiently by a TOSHIBA oriented control
argorithm to achieve savings in energy and space.
Software modification increases output up to a high
frequency of 1000 Hz, making it ideal for woodworking and
metalworking machinery.
A newly developed DC braking function allows the stop time
to a quarter of that on conventional models.
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.
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 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.
