A. Cyclic operation (binary scaling)
Cyclic operation is used when operating with 2
X number of turns
(2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048. 4096... number of
turns). If the desired total measuring range is equal to the speci-
fied single turn resolution * 2 X (where x<= 12) the encoder oper-
ates in endless cyclic operation (0 - max - 0 -max). If the position
value increases above the maximum value by rotating the encod-
er shaft, the encoder continues from 0.
Example of a cyclic scaling:
Measuring units per revolution = 1 000
Total measuring range = 32 000
(2 5 = number of revolutions 32)
