2 / 10 page 2 Definitions Count (N): The number of bar and window pairs or counts per revolution (CPR) of the codewheel. Or the number of lines per inch of the codestrip (LPI) 1 shaft rotation = 360 degrees = N cycles 1 cycle (c) = 360 electrical degree, equivalent to 1 bar and window pair. Direction of Rotation: When the codewheel rotates in the counter-clockwise direction (as viewed from the encoder end of the motor), channel A will lead channel B. If the codewheel rotates in the clockwise direction, channel B will lead channel A. Line Density: The number of window and bar pair per unit length, express in either lines per inch (LPI) or lines per mm (LPmm) Optical Radius (Rop): The distance from the codewheel’s center of rotation to the optical center (O.C) of the encoder module. Gap (G): The distance from surface of the encoder to the surface of codewheel or codestrip Mounting Position (RM): Distance from Motor Shaft center of rotation to center of Alignment Tab receiving hole. Radial and Tangential Misalignment Error (ER and Er): For rotary motion mechanical displacement in the radial and tangential directions relative to the nominal alignment Angular Misalignment Error (EA): Angular misalignment of the sensor in relation to then tangential direction. This applies for both rotary and linear motion.of elec- trical degrees that an output is high during one cycle, nominally 180°e or 1/2 a cycle. Theory of Operation The HEDS-97EX is a C-shaped emitter/detector module. Coupled with a codewheel/codestrip, it translates rotary motion into a two-channel analog output. The module contains a single Light Emitting Diode (LED) as its light source. The light is collimated into a parallel beam by means of a single 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 analog waveforms. The codewheel/codestrip moves between the emitter and detector, causing the light beam to be interrupted by the pattern of spaces and bars on the codewheel/ codestrip. The photodiodes, which detect these interruptions, are arranged in a pattern that corresponds to the radius and count density of the codewheel/codestrip. These detectors are also spaced such that a light period on one pair of detectors corresponds to a dark period on the adjacent pairs of detectors. The photodiode outputs are fed through the signal processing circuitry, which produce the final outputs for Channel A and Channel B. Due to this integrated phasing technique, the analog output of Channel A is in quadrature with Channel B (90 degrees out of phase). |
