ongratulation for purchasing a BMR-GmbH product. We thank you for the decision for choosing a BMR-GmbH device and wish you much success. Please read this manual carefully before the first use Version 06.April.2009

epending 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 motor D.C.), the speed is dependent on the voltage applied. Three-phase A.C. motors provide numerous benefits in industry, such as brushless motor operation, long life, favourable performance/weight ratio, high-speed capability, and much more. These motors can be used in many different application areas, such as milling...

2 Description and Features For the operation of A.C. spindles. The high frequency converter SFU 0150 allows speed frequencies up to 50,000rpm with 2-pole A.C. spindles. Maximum High output power is (150VA) in a compact design. The core of the SFU 0150 is the Digital Signal Processor (DSP) which generates all output signals and captures all input signals. All parameters, such as current, voltage and frequency, are captured in real time, and are adjusted according to load condition by Vector Control Mode. The highest efficiency of motors at both low and high frequencies is made possible....

ATTENTION: Make sure that the setup for mains voltage is in accordance to the power line used.

4 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 work with this device! Any maintenance or repair work on the device must only be carried out when the mains supply plug has been disconnected! Before the first activation can be carried out, it should be established that the tool is installed correctly and securely, to eliminate the possibility of uncontrolled movement of the motor. Safety...

6.2 Setup of Rotational Speed The rotational speed of a connected spindle or the frequency of the output voltage at the spindle terminals can be set up in several ways. Preselection manually via rpm buttons on the front panel The needed speed of rotation can be adjusted with the buttons on the front panel and is displayed on 3 digits on the LED-Display. During operation of the spindle the speed of rotation is displayed with 2 digits. Start, Stop and Setup with the B.M.R foot controler The maximum value of the rotational speed wished can set with the buttons on the front panel. From zero...

6.4 Setup of direction of rotation The direction of rotation may be changed before the start. To achieve this, the push buttons STOP and START have to be actuated simultaneously for about 5 sec (press Stop first, then Start) In this configuration mode it is possible to change the direction between clockwise (displayed: rE) and counterclockwise (displayed: Li) with the help of the RPM push buttons. If the push buttons are left unpressed for more than 10 sec, it is switched back to operating mode. 6.5 Operation If the converter is started and the spindle is spinning, the speed of rotation is...

7 Safety Functions A controlled spindle stop according to the preset acceleration data is carried out because of the events listed below. Converter switch-off, if maximum power consumption is exceeded constantly. In this case the thermofuse with the ON-OFF switch is triggered. Stop because of exceeding the max. internal temperature of the converter after a time delay of 10sec. Stop because of exceeding the max. nominal output load of the converter after a time delay of 10sec. Immediate-Stop because of exceeding maximum spindle current. 8 EMC Electro Magnetic Compatibility This device was...
