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 ...

Description and Features Operation of Asynchronous‐AC –Spindles With optionally available integrated sinusoidal filter for special smoothing of the output signal and operation of low‐voltage spindles. This ensures high attenuation of interference emissions on the motor cables The frequency converter SFU 0300 allows output frequencies up to 4000 Hz / 240.000rpm with 2‐pole asynchronous‐AC‐motors. High Output power (1500VA/S1‐100% ) in a compact format The Kernel of the SFU‐0300 is a Digital Signal Processor (DSP), which generates all output variables and captures signals. ...

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. ...

Connections, Interfaces and Pinouts Operational parameters and outputs: The SFU 0300 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 0300. These assignments can be freely configured. Using the optional Windows PC software SFU‐...

7. Functions, Setup, 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) The errors can be evaluated with the help of the windows software SFU‐Terminal, which is available on the website. The documentation of this software shows how evaluation of these errors is possible. ATTENTION: Where several spindles are in use within one system, the user must ensure that these are of the s

The preset of revolutions per minute of the spindle can be achieved by three ways: Preset manually with the radio knob on the front panel Preset via analogue input Set Value Rotational Speed The default scaling for this input is set up to 1V/10.000rpm Preset via RS232 interface The direction of rotation can be set up before start. For this the key STOP has to be pressed approx. 4sec. In the setup mode it can be switched with the START STOP ‐keys alternating between Right and Left. Right means clockwise rotation with view to the back side of the spindle ...

Due to many different requirements, there are several possibilities for starting and stopping the SFU 0300 frequency converter: Manually with the panel keys controlled remotely via a digital input controlled remotely via an analogue input controlled remotely via serial interface In every case, with the exception of analogue start, the start of the converter is only possible, if a preset of the rotational speed is set up. 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. ...

7.6 Remote‐Controlled Configuration of Direction of Rotation via Digital Inputs This can be achieved via the digital input Direction of Rotation . The setup can be done with SFU‐Terminal software in the 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 ...

The setup of this device can be done in a very flexible and comfortable way with the help of our Windows PC‐Software software SFU‐Terminal. It is available on CD or on our website www.bmr‐gmbh.de/html/british/dokumente/bediensoftware.htm for free. It is possible to administrate spindle characteristics or to configure the functions of inputs and outputs. Moreover there are further functions and useful tools available Die Parametrierung des Geräts ist mit Hilfe der PC‐Software SFU‐Terminal vielseitig und ...
