Description

The SMT1, SMARTach™ Portable Incremental Encoder Signal Analyzer, is a versatile instrument designed to streamline both testing and simulation of incremental encoders, and any other equipment that generates square wave output signals, like linear encoders and flow meteG@ìoptions`Vãì€ìstronAS€¸Ã…´ìceÈoJì°bdì€ìboolean ýÛíoˆ€endtrFa† S€method §òÛíBð‹Ì±Ð€cln, high/low ratio, signal frequency, and current draw. The SMT1 allows for direct testing of incremental encoders through their native connector by the use of a native to 9 Pin D-Sub, adapter cable or through its front panel wiring posts using flying leads like those found on the CBL1 encoder cable. Optional DB9 adapter cables are available with each order and allow for direct testing without having to tear out existing wiring.

Replicate real-world encoder outputs to test and troubleshoot encoder-dependent systems. The SMT1 provides two output modes (continuous and single cycle) with adjustable frequency and selectable phase relationships (A/B or B/A) for comprehensive testing scenarios.

The SMT1 eliminates the need for complex setups and multiple instruments, saving you time and effort. Its large LCD display provides clear test results, while the optional Windows software empowers you with detailed analysis and report generation capabilities.

Whether you’re an engineer, technician, or anyone working with encoders, the SMT1 is an indispensable tool for ensuring proper operation and efficient system testing.

PRODUCT GLOSSARY

A Quad B

A Quad B refers to the set of output quadrature signals from an incremental quadrature encoder to indicate speed and direction, including complements: A, A NOT, B, B NOT (, , , ). Most Avtron encoders offer A Quad B output at no extra cost. For more information on quadrature- Wikipedia: http://en.wikipedia.org/wiki/Quadrature_phase
Complements

Also known as complementary outputs. To ensure that signal noise does not cause errors between the encoder and the controller, many encoders output signals that are driven in exactly opposite directions: when A goes high, A NOT goes low (, ); when A goes low, A NOT goes high. Controllers which see a transition in A, but not in the A NOT signal, would report a quadrature error.
Encoder

A device which indicates position and speed via a set of digital outputs. Incremental encoders output quadrature (A Quad B) signals, and may add a marker pulse once per revolution. Absolute encoders typically indicate position via a digital message, a set of parallel outputs, or analog values.
Incremental Encoder

An encoder that produces pulses in proportion to distance moved or rotated. Incremental encoders can also have a marker pulse Z, Z NOT (, ) once per revolution to provide a position reference. Avtron produces a full range of incremental rotary encoders.
Line Driver

The chip or output circuit that forms the electrical pulses output from the encoder. Avtron has extremely advanced line driver technology to prevent damage from overvoltage and short circuits. Avtron offers optional high-power line drivers to permit Avtron encoder signals to travel farther down long wires to remote controller/drive locations without the need for repeaters or amplifiers.
Marker Pulse

The Marker Pulse occurs once per revolution. The purpose of the marker pulse is to provide a repeatable home position location for positioning applications. The marker pulse is often abbreviated as "�Z" or "Z" in the USA and "C" or "N" in Europe.
Missed Pulses

Errors made by an encoder when a pulse should have been generated due to movement but was not. They are often caused by contamination on optical disks that cause a line to be missed.
Optical Errors

Optical Errors include false pulses, missed pulses, and quadrature errors that are generated when there is any type of contamination (dirt, oil, water, condensation) on the optical disk.
PPR

Pulses Per Revolution. Most Avtron encoders output quadrature pulses, with four times as many lines as pulses. Often lines can be counted in the drive/speed controller for higher resolution applications.
Quadrature

To determine which direction an encoder is revolving, encoders output quadrature signals: two streams of pulses, A & B, generated at 90� timing angles. (Also called A Quad B) A leading B indicates rotation in one direction; B leading A indicates the encoder is rotating in the opposite direction. Example: �A leads B with clockwise rotation as viewed from the encoder face on an HS45 encoder." Many encoders with quadrature outputs also have complementary outputs: A NOT and B NOT signals.
Quadrature Errors

Failures of the encoder to generate properly formatted quadrature signals. Most typically, these are failures to create the proper 90� signal separation between the A and B channel outputs, with a less than perfect stream of square waves. Most controllers, when presented with a quadrature error, will report a drive fault or encoder fault and then shut down.
Rotary Encoder

A rotary encoder provides position and/or speed feedback information about a rotating shaft. Rotary encoders may be hollow shaft, no-bearing modular, coupled solid shaft style. They may provide absolute positioning information, or incremental velocity feedback. Avtron rotary encoders are designed and built to be far more reliable than ordinary rotary encoders. Avtron encoder white papers on our blog provide more details of how and why Avtron rotary encoders are more reliable.
Sensor Crash

When the rotating disk in an encoder contacts the sensor (optical or magnetic/magnetoresistive), it damages or destroys the sensor. Sensor crashes can be caused by excessive vibration, shaft runout, or alignment problems in encoder mounting. Avtron encoders feature Wide-Gap technology to eliminate sensor crashes.
