bmR 1. Introduction The SFU0052 is the successor of the SFU051 and can replace it directly with the exception that the spindle characteristics of the DC version are different and can not be interchanged, but are available at BMR on request. It is implemented an improved DC functions which grants a much better overall performance. The rotational speed of BLDC (brushless direct current) motors is direct depending on the voltage applied. Generally this voltage will be connected to a 3 phase winding on the rotor via a collector, which takes over the proper commutation. BLDC motors have the...

lamp3. Block Schematic PLIM Pouer Supply

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! Any maintenance to the device must be carried out after the supply voltage has been disconnected, only! 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...

7. Description of Functions and Operation SFU 0052-SSE gets all important operating conditions and parameters. A selection of two can be output on the digital outputs as messages All setups described below can easily be carried out with the help of SFU Terminal with a Version higher than V5.9 . The multi purpose input X1-PIN 1 input can be used for setting up the desired rotational speed and in combination for START-STOP During operation the current status is displayed at the LEDs ERROR, RUN, READY The LED ERROR is additionally a common indication for an error. Start and Stop of the...

• Another option of the input scaling is 1V/10.000rpm. As soon as the spindle is started the rotational speed can be increased to maximum The analogue input is protected agains voltages beyond 10V for short time and not for permanent duration 7.4 Load Display At the LED bar the current load condition is displayed as fractions of 100%. As soon as the maximum load is superceded the red LED is lit and the relay at X1-PIN 2-3 is switch. In case that this condition is persisting longer than 10s or longer as the value set up with SFU-Terminal, the spindle is stopped. (see 7.5) 7.5 Status LEDs and...

bmR 5. Safety Functions The following safety functions bring about controlled stop of the spindle according predefined deceleration times • Safety stop because of converter excess temperature after delay-time of 10s is exceeded • Safety stop by overload and time delay exceeded (default 10sec) • Safety stop will occur immediately by exceeding the maximum admissible spindle current. 6. EMC This device was developed for use in industrial environments. For trouble-free operation and to reduce emitted interference, the following should be observed during wiring of the equipment: • The EMC of a...
