3.4.16 Setting of the scaling parameters
The scaling parameters are set in the DDLM_Set_Prm function. The parameters are stored in octets 40 to
47 of the diagnostic data and can be read by the encoder. The parameters "Measuring units per
revolution" and "Total measuring range in measuring units" 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 activated or deactivated.
Values preset by the manufacturer of the encoder:
Measuring units per revolution
Total measuring range in measuring units = singleturn resolution x number of
The data type for both values is 32 bits without sign.
