EnCODER BASICS

Encoders provide motion control systems information on position, count, speed, and direction. As the encoder shaft rotates, output signals are produced, proportional to the distance (angle) of rotation. The signal may be in the form of a square wave (for an incremental encoder) or an absolute measure of position (for an absolute encoder).

Due to the performance and reliability advantages of the semi-conductor technology they incorporate, optical encoders are the preferred solution in many common computer, industrial, and automotive applications. Optical encoders also benefit from ease of customization, are suitable to numerous environments, and suffer no effects from high levels of stray magnetic fields.

The basic construction of an incremental encoder is shown to the right. A beam of light emitted from an LED passes through a transparent disk patterned with opaque lines, and is picked up by a photodiode array. The photodiode array (also called a photosensor) responds by producing a sinusoidal waveform which is transformed into a square wave, or pulse train.

LED

SQUARING

CIRCUIT

DISK

Incremental encoders are available in two basic output types, single channel and quadrature.

A single channel encoder, often called a tachometer, is normally used in systems that rotate in one direction only, and require simple position and velocity information. Quadrature encoders have dual channels (A and B), phased 90 electrical degrees apart. These two output signals determine the direction or rotation by detecting the leading or lagging signal in their phase relationship. Quadrature encoders provide very high speed bi-directional information for very complex motion control applications.

Incremental encoders can provide a once-per-revolution pulse (often called index, marker, or reference) that occurs at the same mechanical point of encoder shaft revolution. This pulse is on a separate output channel (Z) from the signal channel or quadrature outputs. The index pulse is often used to position motion control applications to a known mechanical reference.

Resolution is a term used to describe the Cycles Per Revolution (CPR) for incremental encoders, or the total number of unique positions per revolution for an absolute encoder.

Each incremental encoder has a defined number of cycles that are generated for each full

360 degree revolution. These cycles are monitored by a counter or motion controller and converted to counts for position or velocity control. Absolute encoders generate a unique code word for every resolvable shaft angle (often called bits or counts per revolution).

MOUnTInG AnD MECHAnICAL InSTALLATIOn

For over 40 years, our engineers have been designing encoders that are quick and easy to install. With a variety of mounting options available, your encoder should be a perfect match for your existing equipment. Accessories such as pivoting mounting brackets, measuring wheels, flexible couplings, etc., are available from EPC to ease installation.

The first principle for every encoder installation is "Don't force it!". Striking or using excessive force can either damage your new encoder, or introduce excessive shaft loading, shaft misalignment, or other conditions shortening its expected life. Tighten all couplings and bolts to their recommended torque. Remember, tighter isn't always better!

Shaft Style Encoders

Hollow Bore Encoders

• Gently couple the shaft of the Accu-Coder TM to the driving

shaft, using a correctly sized flexible shaft coupling.

never use a rigid coupling.

• Verify proper alignment between the Accu-Coder TM shaft

and the driving shaft.

• If using pulleys or gears, mount them on the shaft as close

as possible to the Accu-Coder TM to reduce bearing load.

• Axial and radial shaft loading should be low as possible.

Never exceed printed specifications.

• Use recommended torques to tighten all clamping bolts and

couplings.

Make sure driving shaft is free from burrs and other defects.

• With flex mount flush against surface, tighten clamp or set

screws first, then bolt flex mount to surface.

• Check for best possible alignment with hollow shaft and

driving shaft to reduce wobble.

• Runout of the driving shaft, or misalignment between the

driving shaft and the encoder’s hollow bore, decreases the

accuracy and bearing life of the encoder and adds vibration

C-Face Style Encoders

to the system. Re-installing the encoder on the driving shaft

may improve alignment.

• Verify that mounting holes are in exact alignment with holes

or studs on the motor frame.

• Tighten all fasteners with equal torque so as not to distort the

shape of the ring.

Caution: Avoid damage to your Accu-Coder

TM

. The following actions may cause damage, and void product warranty.

Do not shock or strike.

Do not subject shaft to excessive axial or radial shaft stresses.

Do not disassemble.

ELECTRICAL COnnECTIOn

Proper wiring and grounding are essential for the longevity and proper operation of your

Accu-Coder TM . In addition, electrical noise should be minimized to prevent improper counts and/or damage to the electronic components.

Since an Accu-Coder TM can be used with a wide variety of input devices (PLC’s, counters, servo controllers, etc.), from many different manufacturers, it is important to determine proper wiring and connections before installation.

Common Signals

Most Accu-Coder TM encoders have the following electrical connections:

Power, Common or Ground, and one or more Output Signals.

Power (Also called supply, power source, encoder power, +V, or +VDC)

• Always use a direct current (DC) voltage.

• Attach power to the positive (+) side of the power source.

• Verify that the Accu-Coder TM is receiving the proper voltage, since most electrical

failures are caused by an improper or improperly regulated power source.

• The use of surge protection is highly recommended.

Common (Also called Com, supply common, and ground)

• Attach common to the negative (-) side of the power source.

Output Signals (Always at least one, but may be as many as six)

• The most common are A, B, and Z. Commutation outputs include U, V, and W.

• Encoders with a Line Driver output also have the complement (A and A’, B and B’,

etc.) as separate outputs that are used to provide differential signals for reduced

noise and greater drive capability.

never connect the output signals together, or to the power source!

Connections

Verify and match up pin numbers, wire colors, or terminal blocks with the input device.

• Be aware that identification terminology may not always be identical.

• Once proper wiring is determined, document it for future reference.

Cable Routing

Cable length should be minimized by using the shortest route possible.

• All cabling should be installed in dedicated metal conduits, or located at least 12” away

from other wiring.

• Route cables away from high current conductors to minimize pulses caused by

electrical transients.

• Signal wire continuity should be maintained from the encoder to the controller/counter.

Avoid junctions and splices, if possible.

6

Radiated Electrical noise

Noise can be generated by solenoids, relays, motors, starters, and similar devices.

• Using shielded cables will dramatically reduce the effects of noise. Most Accu-Coder

TM

cables are double shielded (foil and braid) for optimum protection.

• Ensure all equipment is properly grounded. (Motors, drives, shafts, etc.)

• Connect encoder cable shield to ground at controller/counter end, leaving the end near

the encoder unconnected. Connecting the shield at both ends can cause ground loops,

and improper operation.

• If possible, use differential line driver outputs with high quality shielded, twisted

pair cable. (Complementary signals greatly reduce common mode noise levels, as well

as signal distortion resulting from long cable lengths.)

• EPC’s line of Repeaters and Converters may help reduce the effects of electrical noise.

TROUBLESHOOTInG

no Output/no Counts

If there is no mechanical movement, there will be no output. Therefore, verify that the

Accu-Coder

TM

is rotating.

• Check to make sure the proper supply voltage is present. It is best to do this at the

Accu-Coder

TM

end, if possible.

• Verify all wiring between the Accu-coder TM , the counter/controller, and the power supply.

• Make sure that the proper signal type (OC, PU, LD, PP) is being used for the

application.

• Verify that the counter/controller is properly installed and operational. Consult the

appropriate User’s Manual if necessary.

• If another Accu-Coder TM is available, try it to determine if the encoder is the problem.

Erratic Output/Missing or Extra Counts

Electrical: Check for loose wiring connections, ground loops, encoder outputs

incompatible with the counter/controller, a noisy power supply, electrical noise, proper

termination of shields, or a combination of these problems.

• Mechanical: Check for improper alignment, loose coupling, or, if used, slippage in the

measuring belt or wheel.

Counts Indicate Wrong Direction

Check for reversed wiring of the quadrature signals. Reverse if needed.

• If differential signals are being used, make sure that both sides are properly wired.

note: If an index pulse is being used, reversing the wiring will cause the

reference alignment to change.

Counts In Only One Direction

Make sure that the counter/controller is capable of, and programmed for, bi-directional

counting.

• On quadrature units, both channels (A and B) must be present and operational. Check

by using a dual channel oscilloscope.

• Make sure the input selection type programmed into the counter/controller, matches the

Accu-Coder TM . If there is a mis-match, the system may not work properly.

Index Pulse not Working

• The index pulse occurs only once per revolution, and can be difficult to check with a volt

meter. Check index pulses with an oscilloscope.

• The counter/controller may not be capable of detecting the index pulse at higher RPM’s.

Slowing down the rotation may allow for detection of the index pulse.

• Verify wiring.

Frequently Answers and Questions

What are the basic types of encoders?
There are two basic output types: single channel (tachometer) and quadrature. Single channel encoders are used for systems rotating in one direction, while quadrature encoders provide high speed bi-directional information for complex applications.
What is the principle of operation of an incremental encoder?
An incremental encoder uses a light beam emitted from an LED passing through a transparent disk with opaque lines, and a photodiode array picks up the light, producing a sinusoidal waveform which is transformed into a square wave.
How should I connect the encoder's output signals?
Never connect the output signals together or to the power source! Verify and match up pin numbers, wire colors, or terminal blocks with the input device. Be aware that identification terminology may not always be identical.
What is the recommended cable routing?
Minimize cable length by using the shortest route possible. Route cables away from high current conductors and use shielded cables for optimum protection. Connect the encoder cable shield to ground at the controller/counter end and avoid junctions and splices, if possible.
What should I do if I encounter missing counts?
Check for loose wiring connections, ground loops, encoder outputs incompatible with the counter/controller, a noisy power supply, electrical noise, proper termination of shields, or a combination of these problems.
