Encoder operation modes
It is possible to use the encoder in 2-channel mode (processing of A and B marks) and in single-channel mode (processing of A mark)
Reference mark processing
It is possible to null the values upon receipt of reference mark signal from the encoder. Software reference mark is also available – in the case if the reference impulse has not been received from the encoder within set time period the value is nulled.
Digital filter
Integrated digital filter is necessary when encoder contact chatter is present. Contact chatter distorts sensor measurement results.

Function

of digital encoders ZET 7060-E

Digital encoder ZET 7060-E is used for measuring distance and rotation angle.

Digital encoders are widely used in printing industry, metal processing, elevator equipment, filling and packaging machines, test benches, handlers and other machinery needing precise register of parts movement.

Operation principle

of digital encoders ZET 7060-E

Digital encoder consists of a primary transducer (encoder) and a measuring unit (module ZET 7060-E). At the output of the primary transducer is formed a signal which is proportional to the parameters of rotation / displacement of the controlled object. This signal is processed by the measuring unit and the data obtained is transmitted in digital format from the output of ZET 7060-E.

Since encoder operating principle is based on photoelectronic raster pattern scanning , the encoder has resolution allowing to measure linear displacement in micrometers and angle in permils of degree.

ZET 7060-E supports connection of incremental linenear displacement, rotation and angle sensors.

Incremental sensors of linear displacement (also referred to as quad encoders) form impulses allowing the receiver to determine current location through calculation of the impulse amount. For the purpose of referencing the system to the starting point incremental sensors have reference marks to be checked after equipment operation start.

Incremental sensors of rotation and angle form impulses allowing the receiver to determine current location through calculation of the impulse amount. For the purpose of referencing the system to the starting point incremental sensors have reference marks (one per rotation) to be checked after equipment operation start.

Connection schemes

of Digital Encoder ZET 7060-E

For determination of distance and direction of the displacement two channels are used (“sin” and “cos”, normally referred to as “A” and “B”). These channels have identical sequences of impulses (square wave) with a relative 90° shift, allowing to determine direction of displacement for linear sensors and direction of rotation for angle sensors.

In addition to “sin” and “cos” modern encorders also have a signal “rotation mark” (“mark”, reference mark, referred to as «Z», «C» or «R»), which together with a less precise trailer allow to determine exact ”zero” position of gear coordinates.

Measuring module ZET 7060-E enables receiving of «A», «B» and zero mark signals as well as as control of the button state (in the case if encoder is controlled by a button).

Based on ZETSENSOR modules one can establish measuring networks, control systems, automated equipment complexes. Interface converters are used for the connection of measuring system to ZETLAB and ZETVIEW systems. ZETLAB software enables connection of up to 200 sensors to a single PC. Measuring networks can also be connected to any system using Modbus protocol via interface RS-485.

Control

of Digital Encoder ZET 7060-E

All necessary settings are stored in the memory of the measuring module ZET 7060-E. If it is necessary to perform configuration of the digital sensor (for instance, due to the change of the primary transducer) one can do this by connecting the device to PC via interface converter ZET 7070 and by starting the application “Device manager”.
