Description and Features
For the operation of
A.C.
spindles.
The high frequency converter
SFU 0150
allows
speed frequencies
up to
50,000rpm
with
2-pole A.C. spindles. Maximum
High output power is (150VA)
in a
compact design.
The core of the
SFU 0150
is the
Digital Signal Processor (DSP)
which generates all output
signals and captures all input signals.
All parameters, such as current, voltage and frequency, are captured in
real time
, and are
adjusted according to load condition by Vector Control Mode.
The
highest efficiency
of motors at
both low and high frequencies
is made possible.
Highest level of operational safety:
All operating states such as acceleration, operation at
rated speed, and deceleration, are monitored and critical situations are intercepted and
brought under control automatically.
Display of Rotational Speed:
current load condition and converter status message on
three 7 segment LEDs.
Control:
The high frequency converter can be controlled manually using 2 push buttons on
the front panel or via the control input on the rear panel.
Galvanic isolation:
spindle voltages and electronics using a mains transformer
Short-circuit-protected
Over-temperature-protected
