Depending on its construction, the speed of a three‐phase asynchronous AC motor is directly dependent on the number of poles and the frequency of the voltage network. In a 3ph/50Hz network, with a 2‐pole motor, the rated speed would be 50 U/s * 60 = 3000 rpm. With synchronous motors (brushless DC), the speed is dependent on the voltage applied Three‐phase AC motors offer numerous advantages in industrial applications, such as brushless drive, no wear, favourable power/weight ratio, high speed capability, and much more. Your field of application is correspondingly diverse, e.g. for driving spindles in milling, ...

Operation of Asynchronous‐AC and Synchronous‐BLDC‐Spindles The frequency converter SFU 0103/0203 allows output frequencies up to 4000 Hz / 240.000rpm with 2‐pole asynchronous‐AC‐motors and 1667Hz/ 100.000rpm with synchronous‐BLDC‐motors. Output power ( 300VA/S1‐100% / 480VA/S1‐100%) in a compact format The Kernel of the SFU‐0103/0203 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 depending on the load condition The highest efficiency of motors at both low and high frequencies is made possible. ...

5. 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. All repairs and maintenance on the converter and the relating accessories must be carried out ...

6. Connections, Interfaces and Pinouts Operational parameters and outputs: The SFU 0103/0203 covers all current important operational parameters and operating data. Up to 5 digital outputs can be used for signalling and 1 analogue value (0...10V) can be output at the analogue output. Remote Control and Outputs: 3 digital inputs (0/24V) and 1 analogue inputs (0...10V) are available for remote control of the SFU 0103/0203. These assignments can be freely configured. Using the optional Windows PC software SFU‐ Terminal the above assignments can be easily achieved, providing exceptional flexibility with ...

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) 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 characteristic ...

7.2 Starting and Stopping the Frequency Converter There are different methods of starting and stopping SFU 0103/0203 AC/DC 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 Manually via panel keys Activation of spindle start via the green START key. Spindle‐stop is activated by the red STOP key on the operator panel. Remote control via digital input Start/Stop by external PLC or CNC Digital Input 1 is the default. To change this, click on the menu ‘digital inputs’. The correct ...

ATTENTION: If an operating mode for starting the inverter has been selected from the list above, it an also only be stopped in this operating mode. This does not apply to the safety functions

The emergency shutdown interlock can be programmed by software „active“ or „inactive“. Programming „inactive“ is insignificant, whereas with a „active“ programming a primary stop‐ command can be given. This means that the converter cannot be started again neither by the „Start‐button“ nor by the remote‐control and that the spindle will be controlled slowed down. To abolish the command „shutdown‐interlock“ there has to be applied a voltage of 5V...30V on the control connector Pin 15 (+) and Pin 8 (⊥). In menu "digital inputs" (SFU‐Terminal) the function RPM direction .can be linked with one ...

LED Load Display Display of Rotational Speed LED Display for Converter Status Mains Switch Potentiometer STOP Button START Button After the Power‐switch is "ON", the Frequency Converter starts if activated, automatically a self‐test on the display. 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 a defect the corresponding display flashes. After pressing the "STOP"‐button the spindle will be electronically decelerated and stopped to standstill. The deceleration time corresponds to the adjusted acceleration time. ...
