The LANG company has been developing step and servo motor controls for fine positioning for almost 30 years. In this scope, the micro step was a milestone in the development. The dynamic micro step operation enables very fast positioning processes with highest accuracy. The LSTEP-controls provide a large number of options and special functions. They have been developed in collaboration with our customers. They are high-resolution step motor controls for 2/4 phase step motors. The dynamic micro step operation enables very fast positioning processes with highest accuracy. On the following...

Overview of the components and the connection possibilities of the LANG - controllers 1. RS 232 and USB port Used for the connection between controller and computer 2. Circuit points for motors Circuit points for servo- (and/) or stepping - motors 3. Encoder TTL-Encoder with 4-fold interpolation Sin.-Cos. Encoder with 8000-fold interpolation (1Vss + MR) For higher absolute accuracy in measuring microscopes For absolute positioning security (no loss of steps ) 4. Digital In.-+Outputs 16 In- and Outputs for 24 Volt For the integration in manufacturing sequences SPS-functionality 5. CAN ֖ Bus...

Joystick Used to move the different axis by hand. 9. LCD-Display For the absolute positioning- and status display. For the manual operation without computer. 10. Keypad (only in conjunction with a display) To enter the positioning data without a computer. 11. s. item 10. 12. Joystick Operation Activation of the joystick after pressing the button. 13. Ready - signal To read off status and interferences In the following, some concepts and properties as well as application examples are described. Resolution: The standard resolution is 250 micro steps per full-step. With a 200 step motor you...

The speed in the LSTEP can be adjusted from 0,01 to 40 revolutions / second. For applications where low speeds are required, there is a possibility of speed reduction, with which it is possible to reduce the speed by factor 100. In our example with 1mm spindle pitch, the slowest speed would be 100nm / second. The max. number of 40 revolutions / second can only be reached with suitable motors (low impedance with slighter Inductivity), and depends on the available motor voltage. In the following you will find a list of the different control types with the available motor voltage. ECO-STEP 24...

Multifunction port: (MFP) The MFP is a 25 pol DSub connector and offers a multitude of functions which are described in the following. Pulse + For-Back Inputs: With these inputs, single axes single axes can be moved independently from the computer via a puls- and direction signal. . Application: - Axes are controlled directly by a video camera - Connection of a track ball for fine positioning -Auto focus Pulse + For-Back Outputs: These outputs can be used, to send pulse and direction signal in order to control external power stages for up to three additional axes . Application: - Handling...

API (Program interface): That LANG-API is the interface between user software and control, and contains the DLLs with all Header-files for the following development environments: ҕ Delphi Visual C++ Օ Visual Basic LabVIEW (with VI-Library) Advantage: The programing time is reduced due to integration of the DLLՒs in the application software. Peculiarity: The API offers the possibility to activate an axes correction in X/Y-matrix with linear Interpolation. WinCommander: - This is a comfortable user software designed for Microsoft WindowsΙ - It is suitable for the beginner to become acquainted...

All-in-oneē compact servo controller for highest dynamic and precision The LSTEP-PP is a 2-axis controller, which can be extended to 3 or 4 axes. It has a very flexible final stages concept, with whom you can control alternatively 2- or 3 phase synchron servo motors (linear / rotativ) or 2/4 phase stepping motors. It works in the capacity range of 48V and max. 5A and allows very quick positioning operations with the utmost of precision. Typical operational fields are: microscopy, wafer inspection and handling, image processing, micro assembly, testing systems ... The controller is...

The LANG positioning-system LSTEP is a high-resolution stepping-motor-control for up to three axes equipped with 2/4 phase stepping motors. The dynamic micro step operation enables fast positioning movements with high accuracy. Thermal radiation is drastically reduced due to pulse-width-modulated power amplifiers used in the electronic control-circuitry. Cooling fans are not required. This kind of positioning system is therefore perfectly suited for clean-room applications. The LSTEP may be operated by hand-terminal CommanderӔ or in combination with a PC via its serial interface RS232....

The LANG positioning-system ECO-STEP is a high-resolution stepping-motor-control for three axes equipped with 2/4 phase stepping motors. The dynamic micro step operation enables fast positioning movements with high accuracy. Standalone operation is possible in joystick-mode. Operation via serial interface R232 is offered by hand-terminal COMMANDER or - in combination with a PC - by the Windows software WIN-COMMANDER. A unique feature of ECOSTEP is the reduction of thermal radiation due to pulse-width-modulated power amplifiers. Cooling fans are not required. This kind of positioning system...
