The SFU400 is developed for the operation of AC-asynchron- and DC-synchron-spindles. speed frequencies up to 1666Hz/100.000 rpm with this 2-pole AC spindle are possible The core of SFU400 is a digital signal processor (DSP) which produces all output parameters and collects signals. High-precision sinusoidal output signals with a low distortion factor and low deformation allow for optimal rotation qualities in AC motors of all operating conditions. All parameters like power, voltage and frequency are collected in real time and are regulated by the implemented vector control depending on the...

The SFU400 inverter is a built-in device intended for installation in stationary electrical, industrial and commercial installations or machines. When installed in machines, it is forbidden to commission the inverter and thus start its intended operation until the machine complies with the Machinery Directive 2006/42/EC. EN 60204 (DIN VDE 0113) must be observed. The machine may only be put into operation for its intended purpose if the EMC Directive (2004/108/EC) is observed. This device produces dangerous electrical voltages and is used for the operation of fast spinning tools. Because of...

Functions, Setup and Operation 5.1 Start / Stopp There are two possibilities to start the spindle: digitally with a digital control signal at digital input1 Start/Stop at X3.DIG_IN. The switching levels for "OFF=0" are 0...5V and for "ON=1" 13...24V, Voltage level between 5V and 13V are undefined. ➔ As soon as this is initiated, the spindle will be accelerated to the set value of the rotational speed which is pre-selected as voltage at analogue input Set Value of Rotational Speed at X3.ANL_IN. analogue with a voltage at X3.ANL_IN Precondition is a valid "ON" signal at digital input...

Example for connecting the I/O Interface For a successful start of the spindle the analogue voltage at ANL_IN has to be higher than the Min-Voltage for Stopp. (→ 5.2). With using a potentiometer for dialing the rotational speed it should be wired to 10V, so that the required range from 0…10V can be covered, representing the speed range. Attention: All these works handle with dangerous voltage and have to be carried out by skilled persons only. Please verify before connecting that the supply voltage is switched off! Attention: Before commissioning, please make sure that all connection...

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 elapsed delay-time Safety Stop because of overload after elapsed delay-time (default 10sec) Immediate-Stop because of exceeding the maximum permissible spindle current When ramping down an asynchronous spindle it can happen that the voltage generated in the spindle will exceed the maximum permissible value. This is detected by the converter and the power stage is switched off for self protection. In this...

USB-Interface für SFU400 On option a remote control unit for direct interfacing with the I/O connection X3 is available. Herewith the communication with the SFU terminal V7.5 for parameterization and debugging is possible very comfortably. …when it comes to quality! BMR GmbH

SFU400 with Remote Control-Adapter On option a remote control unit for direct interfacing with the I/O connection X3 is available. With the help of this unit the converter can be controlled very easily without any further wiring. Starting and stopping becomes possible and all functions can be tested before commissioning and without external control signals. The remote control unit is operated with 3 x AAA Batteries or Accus . All relevant voltages are generated within the adapter For power saveing, an ON/OFF switch is provided. The ready state is indicated at the LED Batt. ON. The switch...
