Incremental Position Encoders！

• Most commonly used type
• Reasonable resolution
• Inexpensive and widely available
• Quality is typically proportional to price
– Poor gratings and poor electronics lead to output signal
orthogonality errors
– Quadrature signals are 90o±No, which cause velocity calculation
errors in control loops

absolute encoder, incremental encoder, hybrid encoder, non-magnetic encoder, multi-turn encoder, multi-turn combination encoder, draw wire encoder, digital readout, linear scale
