Encoding Characteristics
Encoding Characteristics over Recommended Operating Condition and recommended mounting tolerances. These
characteristics do not include codewheel/codestrip contribution. The Typical Values are averages over the full rotation
of the codewheel. For operation above 40 k­Hz, see frequency derating curves.
Note: 3.3 k­Ω pull-up resistors used on all encoder module outputs.
Frequency Derating Curves
Typical performance over extended operating range. These curves were derived using a 5 pF load with a 3.3 k­ pull-up
resistor. Greater load capacitances will cause more error than shown in these graphs.
