SFU 0156
Frequency Converter
1.
Description and Features
Operation of
AC spindles
and
BLDC spindles
The frequency converter
SFU 0156
allows
speed frequencies
up to
2000Hz/120.000 rpm
with
2-pole spindles.
The core of SFU-0156 is a
digital signal processor
(DSP) which produces all output parameters
and collects signals.
High-precision sinusoidal
output signals with a low distortion factor and low deformation
allow for optimal rotation qualities in AC motors of all operating conditions
All parameters like power, voltage and frequency are collected in
real time
and are regulated
by the implemented vector control depending on the load.
High
operating safety:
All operating conditions like acceleration, operation with nominal
rotation speed, braking are controlled and critical conditions are intercepted.
Short circuit protected
on board chopper resistor
Protection against excess temperature.
