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...

Description and Features Operation of a.c. and bldc spindles The frequency converter SFU 0102/0202 allows output frequencies up to 200 Hz / 120,000Upm with 2-pole AC motors and 1000Hz/ 60,000Upm with Bloc-motors. Output power ( 250VA-0102 / 400VA-0202 ) 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. The highest efficiency of motors at both low and high...

Safety-Precautions and Warnings This device produces dangerous electrical voltages and is used for the operation of fast spinning tools. Because of their high rotational speed, it may be dangerous in case of improper handling. For this reason, only professionally trained and qualified personnel should be allowed to work with and setup this device! Before the first commissioning can be carried out, it should be ensured that the spindle and the tool are fixed properly, to eliminate all dangers because of uncontrolled movement of the spindle. Safety regulations being valid for the country...

Connections, Interfaces and Pinouts Operational parameters and outputs: The SFU 0102/0202 covers all current important operational parameters and operating data. Up to 6 digital outputs can be used for signalling and up to 1 analogue values can be output to the analogue outputs (0-10V). Remote Control and Outputs: 6 digital inputs (24V) and 1 analogue inputs (0-10V) are available for remote control of the SFU 0102/0202. These assignments can be freely configured. Using the optional Windows PC software SFUTerminal the above assignments can be easily achieved, providing exceptional...

Functions, Commissioning, Operation 3 operational possibilities: Control and configuration manually via front keys Automatic control and configuration via PLC / IPC Automatic control and configuration via PC (RS232 interface) Setup and control of the features and functions listed below can be carried out with our setup software SFU-Terminal. All explanations and hints to menu functions relate to this software. CAUTION: The operation of a spindle with a wrong spindle characteristic may cause severe damages at spindle or converter. To avoid this, please ensure that the correct spindle...

7.2 Starting and Stopping the Frequency Converter There are different methods of starting and stopping SFU 0102/0202 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 of spindle start via the green START key. Spindle-stop is activated...

7.3 Remote-Controlled Configuration of Direction of Rotation via Digital Inputs Via digital input RPM direction . Setup is carried out in menu ‘digital inputs’. This is necessary, if the direction of rotation has to be controlled , for example, via a PLC. Reversal can only take place once the spindle / motor has come to a complete stop. If the direction pre-selection setting is changed whilst the spindle / motor is running, the spindle / motor will not turn in the new direction until it has been brought to a complete standstill and then restarted. 7.4 Safety stop functions As shown above,...

During this time all displays flashes a short time one after another. After this automatical check the converter is ready for operation. In case of defect the corresponding display flashes. Spindle "Start" After pressing the „START“-button the spindle starts to come up to the rotational speed adjusted by...
