Interpolation and Counter Card MVSPCIe

■ Patented gain and offset regulation

■ Maximum input frequency of 260 kHz for all resolutions

■ Absolute measurement accuracy due to continous data acquisition in realtime (< 4 us)

The MVSPCIe interpolation and counter board from GEMAC provides fast, synchronous and equidistant

acquisition and evaluation of four analog and four digital incremental encoder signals. As a space-saving and

cost-effective alternative to an external electronic system, the MVSPCIe offers maximum application

possibilities for highly dynamic processes. To this end, the user can choose from numerous functions and

delivery scopes of the board. Furthermore, GEMAC provides support in the form of individual consulting and

factory-set board configuration, if necessary.

The signals from the analog encoder are corrected automatically in amplitude and zero position by way of

the patented GEMAC control algorithm. Subsequently, the integrated electronic interpolation unit divides the

signal period of the encoder into max. 2,048 increments. Due to the automatic closed-loop control, an

absolute measuring accuracy (typ. ±0.7 increments) is achieved in realtime of less than four microseconds.

In addition to the signals from the incremental sensors, the MVSPCIe also acquires another analog signal

and up to 11 further digital signals simultaneously. Acqusition of the measured values is triggered by a

programmable timer or externally connected components, e.g. a trigger sensor or camera.

For the evaluation of distance-coded reference marks, it is also possible to start a measurement via the

reference signal from one or several sensors.

Applications:

■ Machines used for quality surveillance (coordinate measuring machines, special measuring machines)

■ Automation and control solutions (components for industrial PCs)

■ Fast and synchonous detection of position values and other physical values simultaneously

■ Detection of position values and position differences depending on trigger occurences
