Scaling parameters settings
The scaling parameters are set in the DDLM_Set_Prm function.
The parameters are stored in the octets 40 to 47 of the diagnostic
data. The “Measuring units per revolution” and “Total measuring
range in measuring units” parameters define the selected
resolution of the encoders. The status bit of the scaling function in
the operating status (octet 9 of the diagnostic data) indicates
whether the scaling function is enabled.
Values preset by the manufacturer of the encoder:
Measuring units per revolution = singleturn resolution.
Total measuring range in measuring units = singleturn
resolution x number of distinguishable revolutions.
The data type for both values is unsigned 32 bits.
