1. Introduction Depending on its construction, the speed of a three-phase a.c. motor is directly dependent on the number of poles and the frequency of the network. In a 3ph 380V/50Hz network, with a 2-pole motor, the rated speed would be 50 U/s * 60 = 3000 Upm. With d.c. motors (brushless d.c.), the speed is dependent on the voltage applied. Three-phase a.c. motors provide numerous benefits in industry, such as brushless operation, freedom from wear and tear, favourable capacity/weight ratio, high-speed capability, and much more. These motors can be used many different application areas, such...

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...

CAUTION: To avoid severe motor / spindle damage, select correct motor / spindle characteristic !

5. Safety-Precautions and Warnings • This device produces dangerous electrical voltages and is used for the operation of dangerous moving mechanical parts. For this reason, only professionally trained and qualified personnel should be allowed to install and repair this device! • Before first activation of the device, verify, if it id in a faultless condition. If it was damaged during shipping and transportation it must not be switched on. • During installation the safety regulations have to be observed. • Before the device is turned on for the first time, it should be verified, that the connected...

Operational parameters and outputs: The SFU-0302 covers all current important operational parameters and operating data. Up to 6 digital outputs can be used for signalling and up to 2 analogue values can be output to the analogue outputs (0-10V) . Remote Control and Outputs: 6 digital inputs (24 V) and 2 analogue inputs (0-10V) are available for remote control of the SFU-0302. These assignments can be freely configured. Using the optional Windows PC software SFU0302 the above assignments can be easily achieved, providing exceptional flexibility with each application Each operating parameter can...

7.3 Configuration via the Front Keys STOP and OK , the Menu Spindle Characteristic Menu settings can only be adjusted when the device has come to a complete standstill. By simultaneously pressing the keys Setting will appear: Select the number of the spindle characteristic using the | UP | and DOWN keys. Spindle Characteristic : • Standard: A number of spindle characteristics are already implemented. Existing characteristics can be loaded and displayed using the PC software SFUTerminal. • Variants for Hofer motors: all spindle characteristics for Hofer-Motors are implemented exworks. The LCD...

7.5 Starting and Stopping the Frequency Converter (all references to menues relate to setup software SFU-Terminal) There are different methods of starting and stopping SFU-0302 frequency converters, due to many different requirements, as follows below: • manually via panel keys • Remote control via digital input • Remote control via analogue input • Remote control via serial interface Before starting the converter is possible, a preset of the RPM (> 7.4) has to be done. This is necessary for all options of starting with the exception of analogue starting. Manually via panel keys _ Activation...
