Recommended Operating Conditions
Note: The module performance is guaranteed to 20 kHz but can operate at higher frequencies. For operation at 30KHz for resolution options E, F,
G and H, the maximum pulse width and logic state width errors are 40°e and phase error is 15°e.
Encoding Characteristics
Encoding Characteristics over Recommended Operating Range and Recommended Mounting Tolerances. These
characteristics do not include codewheel/codestrip contributions.
Case 1: Module mounted on tolerances of ±0.13 mm (0.005”). Case 2: Module mounted on tolerances of ±0.25 mm
(0.010”)
Note: See Figures in Mounting Considerations for details on Case 1 and Case 2 mounting tolerances.
Electrical Characteristics
