Additional information

  • ENCODER OPERATION MODE

    Encoder can operate in a double-channel mode (processing A and B marks) and in a single-channel mode (processing mark A only)

  • PROCESSING REFERENCE MARK

    Value on receipt of the reference mark from the encoder can be reset. There also is a software reference mark: if no new pulse is received from the encoder within a certain period of time, the value will be reset.

  • DIGITAL FILTER

    The integrated digital filter is required in case of encoder’s mechanical contacts chattering. The contact chattering may cause wrong indications of the sensor.

Purpose

of the Digital encoder ZET 7160-E

The digital encoder ZET 7160-E is intended for distance and rotation angle measuring.

The encoders are widely used in the printing industry, metal work industry, elevator engineering, pre-packing, packing and bottling machines, in test benches, as well as in robots and other machines requiring accurate registration of parts movement indicators.

Operating Principles

of the ZET 7160-E Digital Encoders

The digital encoder consists of a primary transducer (encoder) and the measuring element (ZET 7160-E unit). A signal proportionate to the studied object rotation/displacement parameters is formed at the primary transducer output. This signal is processed by the measuring element and the values obtained are transferred from ZET 7160-E unit output in a digital form.

According to the encoder operating principle, photoelectronic raster scanning, when measuring linear displacements, the encoders have a resolution measured in micrometers, and when measuring angles, the resolution constitutes just several thousandth of degree.

Linear displacement, rotation and angle incremental sensors can be connected to the ZET 7160-E unit.

Linear displacement incremental sensors also called quad encoders, generate pulses by means of which the receiving device determines the current position of the coordinate by pulse counting by the counting device. For binding the coordinates system to the reference point, the incremental sensors have reference points to be processed after the equipment power on.

Rotation and angle incremental sensors generate pulses by means of which the receiving device determines the current position of the coordinate by pulse counting by the counting device. For coordinate system binding, the incremental sensors have a reference mark (“marker”), one per rotation, which is to be processed after the equipment power on.

CONNECTION DIAGRAMS

To determine the distance and rotation direction, two channels (“sine” and “cosine”, usually referenced as “A” and “B”) are used, in which the identical pulse sequences (meander) have a shift of 90° relative to each other, which allows the user to determine the displacement direction for linear, and rotation direction for angular, sensors.

Besides “sine” and “cosine” channels, the modern encoders also use the “reverse mark” signal (“marker”, a reference mark usually referenced as “Z”, “C” or “R”) which, in combination with less accurate limit switch, allows the user to determine the precise “zero” position of the drive coordinate.

The ZET 7160-E measuring unit makes it possible not only receive “A” and “B” signals and the zero mark, but to control the button state as well, when button encoders are connected.

The ZETSENSOR sensors are used to build digital systems: distributed measuring networks, control systems, and automated complexes. Interface converter is used for connecting the measurement network to ZETLAB and ZETVIEW systems. The ZETLAB software supports connection of up to 200 gauges to a single computer.

CONTROL

of the ZET 7160-E Digital Encoders

All required settings are stored in the memory of ZET 7160-E measuring unit at factory. When independent setting of a digital gauge is required, for instance, in case of replacement of a primary transducer, it is possible to do so by connecting the unit to a computer via ZET 7174 or ZET 7176 interface converter and launching Device Manager.
