2. Description and Features
•
Operation
of
a.c. and d.c. motors/spindles
•
The frequency converter SFU-0302 allows speed frequencies up to 180,000Upm with 2-pole
a.c. motors and 60,000Upm with d.c. motors.
•
High output power ( 3,6kVA@230V / 2kVA@115V ) from a compact design
•
The Kernel of the SFU-0302 is a Digital Signal Processor (DSP), which generates all output
variables and captures signals.
•
All parameters, such as current, voltage and frequency, are captured in real time, and adjusted
by implementing via the Vector Control according to loading.
•
Highly-accurate sinusoidal output signals with low harmonic distortion, facilitate the smooth
running of a.c. and d.c. motors/spindles under all operational conditions.
•
The
highest efficiency of motors at both low and high frequencies is made possible.
•
High level of operational safety. All operating states such as acceleration, operation at rated
speed, and deceleration, are monitored and critical statuses are intercepted and brought under
control. This also includes the controlled deceleration of the motor / spindle in the event of
power failure or Emergency Stop.
•
Integrated braking resistor for reduced external wiring.
•
Transparency: The user is continuously informed of the status of the frequency converter and
the motor / spindle by means of a 4-column plain-text display on the front panel.
•
Control: The frequency converter can be manually controlled and calibrated as required using 6
keys on the front panel.
•
Individual adaptation to the application in hand and the spindle in use. Up to 16 different spindle
characteristics can be created and stored in the memory of the frequency converter, or existing
characteristics can be modified and adapted to the application.
•
Diverse control and communication possibilities. 3 types of connection are available to
facilitate communication using peripheral devices - PC , PLC (Programmable Logic Control), CNC
(Computer Numeric Control).
•
Straight-forward and flexible integration into existing systems by means of open configuration
of I/O signals for control and configuration:
Control inputs:
2 analogue, 6 digital
Control outputs:
2 analogue, 6 digital (relay)
•
Galvanic separation of all interfaces from each other and from the network / motor potential
•
Short-circuit-protected
•
User-friendly configuration and control using optional Windows Software for the PC
•
Automatic spindle detection, if supported by the spindle
