Technical Data

HEDS-550x/554x

HEDS-560x/564x

Features

HEDS-5500/5600 and HEDM-

5500/ 5600 are two square waves

in quadrature. The HEDS-5540

and 5640 also have a third chan-

nel index output in addition to the

two channel quadrature. This

index output is a 90 electrical

degree, high true index pulse

which is generated once for each

full rotation of the codewheel.

• Two Channel Quadrature

Output with Optional Index

Pulse

• Quick and Easy Assembly

• No Signal Adjustment

Required

• External Mounting Ears

Available

• Low Cost

The HEDS series utilizes metal

codewheels, while the HEDM

series utilizes a film codewheel

allowing for resolutions to 1024

CPR. The HEDM series is nont

available with a third channel

index.

Applications

• Resolutions Up to 1024

Counts Per Revolution

• Small Size

• -40°C to 100°C Operating

Temperature

• TTL Compatible

• Single 5 V Supply

The HEDS-5500, 5540, 5600,

5640, and the HEDM-5500, 5600

provide motion detection at a low

cost, making them ideal for high

volume applications. Typical

applications include printers,

plotters, tape drives, positioning

tables, and automatic handlers.

These encoders may be quickly

and easily mounted to a motor.

For larger diameter motors, the

HEDM-5600, and HEDS-5600/

5640 feature external mounting

ears.

Description

Note: Agilent Technologies

encoders are not recommended

for use in safety critical

applications. Eg. ABS braking

systems, power steering, life

support systems and critical care

medical equipment. Please

contact sales representative if

more clarification is needed.

The HEDS-5500/5540, HEDS-

5600/5640, and HEDM-5500/

5600 are high performance, low

cost, two and three channel

optical incremental encoders.

These encoders emphasize high

reliability, high resolution, and

easy assembly.

The quadrature signals and the

index pulse are accessed through

five 0.025 inch square pins

located on 0.1 inch centers.

Each encoder contains a lensed

LED source, an integrated circuit

with detectors and output

circuitry, and a codewheel which

rotates between the emitter and

detector IC. The outputs of the

Standard resolutions between 96

and 1024 counts per revolution

are presently available. Consult

local Agilent sales representatives

for other resolutions.

ESD WARNING: NORMAL HANDLING PRECAUTIONS SHOULD BE TAKEN TO AVOID STATIC DISCHARGE.

Theory of Operation

Block Diagram

The HEDS-5500, 5540, 5600,

5640, and HEDM-5500, 5600

translate the rotary motion of a

shaft into either a two- or a three-

channel digital output.

As seen in the block diagram,

these encoders contain a single

Light Emitting Diode (LED) as its

light source. The light is

collimated into a parallel beam by

means of a single polycarbonate

lens located directly over the

LED. Opposite the emitter is the

integrated detector circuit. This

IC consists of multiple sets of

photodetectors and the signal

processing circuitry necessary to

produce the digital waveforms.

The final output of channel I is an

index pulse P_Owhich is generated

once for each full rotation of the

codewheel. This output P_Ois a

one state width (nominally 90

electrical degrees), high true

index pulse which is coincident

with the low states of channels A

and B.

revolution.

The codewheel rotates between

the emitterand detector, causing

the light beam to be interrupted

by the pattern of spaces and bars

on the codewheel. The

photodiodes which detect these

interruptions are arranged in a

pattern that corresponds to the

radius and design of the

codewheel. These detectors are

also spaced such that a light

period on one pair of detectors

corresponds to a dark period on

the adjacent pair of detectors. The

photodiode outputs are then fed

through the signal processing

circuitry resulting in A, A, B and B

(also I and I in the HEDS-5540

and 5640). Comparators receive

these signals and produce the

final outputs for channels A and

B. Due to this integrated phasing

technique, the digital output of

channel A is in quadrature with

that of channel B (90 degrees out

of phase).

Pulse Width (P): The number of

electrical degrees that an output

is high during 1 cycle. This value

is nominally 180°e or 1/2 cycle.

Pulse Width Error (∆P): The

deviation, in electrical degrees, of

the pulse width from its ideal

value of 180°e.

Definitions

Count (N): The number of bar

and window pairs or counts per

revolution (CPR) of the

codewheel.

State Width (S): The number of

electrical degrees between a

transition in the output of channel

A and the neighboring transition

in the output of channel B. There

are 4 states per cycle, each

nominally 90°e.

One Cycle (C): 360 electrical

degrees (°e), 1 bar and window

pair.

State Width Error (∆S): The

deviation, in electrical degrees, of

each state width from its ideal

value of 90°e.

One Shaft Rotation: 360

mechanical degrees, N cycles.

Position Error (∆Θ): The

normalized angular difference

between the actual shaft position

and the position indicated by the

encoder cycle count.

Phase (φ): The number of

electrical degrees between the

center of the high state of channel

A and the center of the high state

of channel B. This value is

nominally 90°e for quadrature

output.

In the HEDS-5540 and 5640, the

output of the comparator for I

and I is sent to the index

processing circuitry along with

the outputs of channels A and B.

Cycle Error (∆C): An indication

of cycle uniformity. The differ-

ence between an observed shaft

angle which gives rise to one

electrical cycle, and the nominal

angular increment of 1/N of a

Phase Error (∆φ): The deviation

of the phase from its ideal value

of 90°e.

Encoder Mounting and Assembly

1. For HEDS-5500 and 5600: Mount encoder base plate onto

motor. Tighten screws. Go on to step 2.

2. Snap encoder body onto base plate locking all 4 snaps.

1a. For HEDS-5540, 5640 and HEDM-5500, 5600: Slip

alignment tool onto motor shaft. With alignment tool in

place, mount encoder baseplate onto motor as shown above.

Tighten screws. Remove alignment tool.

4. Use the center screwdriver slot, or either of the two side

slots, to rotate the encoder cap dot clockwise from the one

dot position to the two dot position. Do not rotate the

encoder cap counterclockwise beyond the one dot position.

3a. Push the hex wrench into the body of the encoder to

ensure that it is properly seated into the code wheel hub set

screws. Then apply a downward force on the end of the hex

wrench. This sets the code wheel gap by levering the code

wheel hub to its upper position.

The encoder is ready for use!

3b. While continuing to apply a downward force, rotate the

hex wrench in the clockwise direction until the hub set

screw is tight against the motor shaft. The hub set screw

attaches the code wheel to the motor's shaft.

3c. Remove the hex wrench by pulling it straight out of the

encoder body.
