HEDM-55xx/560x & HEDS-55xx/56xx Quick Assembly Two and Three Channel Optical Encoders Data Sheet HEDM-55xx/560x HEDS-550x/554x, HEDS-560x/564x The HEDS-5500/5540, HEDS-5600/5640, HEDM-5500/5540 and HEDM-5600 are high performance, low cost, two and three channel optical incremental encoders. These encoders emphasize high reliability, high resolution, and easy assembly. 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 HEDS-5500/5600 and HEDM-5500/ 5600 are two square waves in quadrature. The HEDS-5540/5640 and HEDM-5540 also have a third channel 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. The HEDS series utilizes metal codewheels, while the HEDM series utilizes a codewheel allowing for resolutions to 1024 CPR. 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. The quadrature signals and the index pulse are accessed through inch square pins located on inch centers. x Two channel quadrature output with optional index pulse The HEDS-5500, 5540, 5600, 5640, and the HEDM-5500, 5540,5600 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. Note Avago 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 is needed.

I, the index output. Theory of Operation The HEDS-5500, 5540, 5600, 5640, and HEDM-5500, 5540, 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 codewheel rotates between the emitter and 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 HEDS5540/5640 and HEDM-5540 . Comparators receive these signals and produce the 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 . In the HEDS-5540/5640 and HEDM-5540, 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. The output of channel I is an index pulse PO which is generated once for each full rotation of the codewheel. This output PO is a one state width nominally 90 electrical degrees , high true index pulse which is coincident with the low states of channels A and B. Block Diagram One Cycle C 360 electrical degrees °e , 1 bar and window pair. One Shaft Rotation 360 mechanical degrees, N cycles. Position Error The normalized angular between the actual shaft position and the position indicated by the encoder cycle count. 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 The deviation, in electrical degrees, of the pulse width from its ideal value of 180°e. State Width S The number of electrical degrees between a transition in the output of channel A and the neighbouring transition in the output of channel B. There are 4 states per cycle, each nominally 90°e. State Width Error The deviation, in electrical degrees, of each state width from its ideal value of 90°e. Phase 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. Phase Error The deviation of the phase from its ideal value of 90°e.

The HEDS-5540 and 5640 must be aligned using the aligning pins as in Figure 3, or using the alignment tool as shown in “Encoder Mounting and Assembly”. See also “Mounting Considerations.” The recommended mounting screw torque for 2 screw and external ear mounting is kg-cm in-lbs . The recommended mounting screw torque for 3 screw mounting is kg-cm in-lbs . Electrical Interface To insure reliable encodingperformance, the HEDS5540/5640 and HEDM-5540 three channel encoders require kΩ ± 10% pull-up resistors on output pins 2, 3, and 5 Channels I, A, and B as shown in Figure These pullup resistors should be located as close to the encoder as possible within 4 feet . Each of the three encoder outputs can drive a single TTL load in this The HEDS5500, 5600, and HEDM-5500, 5600 two channel encoders do not normally require pull-up resistors. However, kΩ pull-up resistors on output pins 3 and 5 Channels A and B are recommended to improve rise times, especially when operating above 100 kHz frequencies. Figure Pull-up Resistors on HEDS-5X40 and HEDM-5540 Encoder Outputs. 7 Mounting Considerations The HEDS-5540 and 5640 three channel encoders and the HEDM Series high resolution encoders must be aligned using the aligning pins as in Figure 3, or using the HEDS-8910 Alignment Tool as shown in Encoder Mounting and Assembly. The use of aligning pins or alignment tool is recommended but not required to mount the HEDS-5500 and If these two channel encoders are attached to a motor with the screw sizes and mounting tolerances in the mechanical characteristics section without any additional mounting bosses, the encoder output errors will be within the maximums in the encoding characteristics section. The HEDS-5500 and 5540 can be mounted to a motor using either the two screw or three screw mounting option as shown in Figure The optional aligning pins shown in Figure 3 can be used with either mounting option. The HEDS-5600, 5640, and HEDM-5600 have external mounting ears which may be used for mounting to larger motor base plates. Figure 4 shows the necessary mounting holes with optional aligning pins and motor boss. Figure Mounting Holes. Figure Optional Mounting Aids.

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. The encoder is ready for use!

Electrical Interface

To insure reliable encodingperformance, the HEDS5540/5640 and HEDM-5540 three channel encoders require kΩ ± 10% pull-up resistors on output pins 2, 3, and 5 Channels I, A, and B as shown in Figure These pullup resistors should be located as close to the encoder as possible within 4 feet . Each of the three encoder outputs
can drive a single TTL load in this The HEDS5500, 5600, and HEDM-5500, 5600 two channel encoders do not normally require pull-up resistors. However, kΩ pull-up resistors on output pins 3 and 5 Channels A and B are recommended to improve rise times, especially when operating above 100 kHz frequencies.

The HEDS-5540 and 5640 three channel encoders and the HEDM Series high resolution encoders must be aligned using the aligning pins as in Figure 3, or using the HEDS-8910 Alignment Tool as shown in Encoder Mounting and Assembly.

The use of aligning pins or alignment tool is recommended but not required to mount the HEDS-5500 and If these two channel encoders are attached to a motor with the screw sizes and mounting tolerances in the mechanical characteristics section without any
