•
CMR must be smaller than or equal to the physical measuring range supported by the en-
coder.
This function is currently
not
implemented for the ATM60/ATM90 encoders.
6.1.3 Case b) Adapted Scaling Functions (without Offset)
The scaled measuring range is mapped completely in the physical measuring range. The cus-
tomer-specified value for CMR is matched to obtaining a 2
N
value for the relationship between
CMR and CPR (there is no
offset
). – The following settings are also valid:
•
R =
2
**N
, with N = {0,1, …13}, R= CMR/ CPR (with CMR being a multiple of CPR
•
CMR
≤
PMR.
The table below shows some configurations for adhering to the limits defined:
