Function The absolute angle information derived by the encoder is converted into serial information by an internal parallel-serial converter and then transmitted to a receiving electronic circuit in synchronism with a clock. Important advantages are : Low number of data lines and high reliability. Maximum data transmission rate The date rate ist defined by the following factors: □ Clock frequency 1 MHz max up to 40 meters connection line □ Delay time of the overall electronics (between 40 and 150 meters) t = t + 2t + t GV C K E t : Total delay time tC: Delay time of the encoder electronics,...

Rotary encoder TMN42 - 4

Model TMA 42: Analogue outputs 0-20 mA, 4-20 mA, 0-10 VDC or ±10 VDC Function The contactless electromagnetic sensor system is extended with a 12-bit D/A converter so that the measured variable is available as an analogue signal from 0 (4) to 20 mA, 0 to 10 V or ± 10 VDC. Measuring range setting The rotary encoder is equipped with a maximum measuring range of 15 bits, i.e. 32,768 revolutions. As standard, the measuring range is therefore set to 3600°, i.e. 10 revolutions and CW (increasing values clockwise viewed looking towards the sensor shaft) as the code direction. Pre-set measuring...

Functional description and adjustement modes The following parameters can be adjusted by the user in situ: Code sense, zero point, end point and default values, via the multifunctional entries MFP 0 and 1 (entry circuit E8 respectively E9). Before delivery the measuring range will be set at 0 to 3600 degree and the code sense increasing CW with view to the shaft end. If the user chooses a smaller measuring range, e.g. 2700°< there will be an overflow when leaving the specified range. In this event the output signal keeps its maximum level, i.e. 20 mA up to 3600°<. The Analogue Hand...
