SFU 0303 Frequency Converter
2. Description and Features
Operation of Asynchronous AC und BLDC Motors
The high frequency converter SFU-0303 makes possible output frequencies 3.3 kHz / 200.000 Upm
with 2pole AC-Motors and with BLDC-Motors up to 100.000rpm
High output power ( 3,6kV @ 230V / 2kVA @ 115V ) in compact style
The core of SFU-0303 is a Digital Signal Processor (DSP) which produces all output signals and collects
all input signals
All parameters like current, voltage and frequency are collected in real time and are regulated by the
implemented vector control depending on the load condition.
High precision sinusoidal output signals with low distortion factor realize very high accuracy in true
running behavior.
Allows highest efficiency of the spindles at low and high frequencies
High operational safety : All operating conditions like acceleration, operation with nominal rotational
speed, deceleration is monitored and critical conditions are intercepted.
Integrated braking resistance (brake chopper).
Without brake chopper the deceleration times down
to standstill can be longer.
Transparency : The user is always informed about the current status of the converter and the spindle
on a plain text and detachable operating panel at the front panel.
Control: If needed, the converter can be controlled and parameterized manually with a pluggable
operating unit.
Easy reversing the direction of rotation by Software without loss of power .
Individual adjustment to the current application and the connected spindle. Up to 16 different
characteristics can be stored in the converter
A variety of options for control and communication possibilities
: For communication with peripheral
devices, such as PC, PLC or CNC, there are 3 ports available:
Easy and flexible integration into existing equipments by free configuration of I/Os
Control inputs: 2 Analog, 6 Digital
Control Outputs: 2 Analog, 6 Digital (Relay)
Galvanic separation of all interfaces from each other and from mains / spindle potential
Short circuit proof
Comfortable Configuration und control with the help of a PC-Windows software "SFU-Terminal"
Cloning-Function with operating panel: Creating of clones of converters by individual read out of the
SFU-parameters into the operation panel and download into another or multiple SFUs.
Automatic spindle calibration by autotuning function
