... INCREMENTAL ENCODER DESCRIPTION The device iC- evaluator IC for optical increment linear and rotary motion sensors, e.g. glass scales or shaft encoders. A photodiodes array supplies the input signals for the monolithically integrated amplifiers, comparators and the TTL compatible push-pull output drivers. Two tracks, A and B, are evaluated differentially, the index track constant light ...

... Figure 1 illustrates the layout of the entire electronic system of an incremental rotary encoder. The devices iC-OR (photodiodes array), iC-WT (incremental encoder) and iC-WE (line driver) from iC-Haus are used. The rotary encoder requires the supply voltages VCC= +5V and VB= +5V to +30V (line driver) and supplies the conditioned signals of tracks A and B and index track Z at the outputs. It’ ...

... TRI). An error detector monitors the chip temperature as well as the supply voltages VCC and VB. In the event of a fault, the open-collector output NER is switched low and the output stages are switched to high impedance to prevent destruction. The error signal of the incremental encoder iC-WT can be switched through to the output NER via the error input TNER. ...

... INCREMENTAL ENCODER DEMO BOARD The demonstration board provides a survey over the properties of the iC-WT simply and easily. The encoder IC is already connected to the necessary external components. In addition, the board contains subunits which can be utilized to have measurements performed - even without a rotary encoder. Figures show the wiring as well as the top and bottom layout of the test PCB ...

... A regulated power supply of +5V dc must be applied between VCC and GND for all measurements. Since the iC-WT operates with very low sensor currents, the work surface should possess an insulated screen (e.g. a single sided copper-clad plate) which is connected to GND. AGND is pulled down to GND inside the iC-WT and should not be interconnected externally. The transmit LED of the rotary encoder can be connected between LED and VCC ...

... INCREMENTAL ENCODER Modulating ACA around its mean value functions like a linear differential activation of the inputs DPA and DNA. The modulation limits are V and appropriate rectangular signal can be picked off at output A with an oscilloscope. For a pulse duty factor of 1:1 it may be necessary to readjust the temperature-dependent medium voltage at ACA. In addition, at high frequencies over 200kHz the parasitic capacities of the test circuit affect the activation and thus the output signal ...
