Codewheel Design Example
The following example demonstrates a codewheel design for a Rop of 11 mm @ 828 CPR for a typical 2 channels encoder.
In the case for an index track design, special index tracks have to be utilized.
Codewheel pattern for a 2 channels encoder
Codewheel pattern for a 3 channels encoder
Notes:
a). 2 tracks from the original 828 CPR, 2 channels codewheel design have been utilized for the special track(Index), but CPR remains the same.
Codewheel Characteristics
The most important dimension to remember is that the index (I) channel pattern on the codewheel, the width angle is
made up of 3 x WB° (opaque-non reflective region).
Caution: As the Index track is generated by utilizing the 3xWB (opaque – non reflective)
region, any dirt that blocked the tracks resulting in the encoder’s detector sensing
a 3x WB will result in another erroneous Index.
LW = 1.8 mm (minimum)
Index track width angle is made up of 3 x W B°
