Example of an incremental encoder with 10.000 pulses/revolution:
count. range of rotary table in actual measuring units:... 360.0
edge evaluation (3/1): .................................................... single (factor 1)
mechanical transmission: .............................................. 1:1
multiplier (3/3): ............................................................... 0.3600
value
to be programmed (3/ 8 ) = (360.0 / 0.3600)
∗
(4 / 1) = 4000.0
Only positive values can be entered for the setting of lengths nominal values.
In operation, negative lengths are, however, achieved for values that are larger
than half of the counting range. Thus, a certain travelling direction can be
forced for the drive by an appropriate selection of the nominal length.
Example with the data from the previous exampIe:
desired nominal length: -100.0 (the drive shall move backward by 100.0)
nominal value to be entered
: 360.0 – 100.0 = 260.0 (> 360.0 / 2 !)
