3.3.5 Scaling
To ensure that the position value exactly matches the variables to be physically
measured, an adjustment can be carried out via the scaling parameters. The scalable
parameters are "Measuring units per revolution (MUPR)" and "Total measuring range
in measuring units (TMR)".
The scaling parameter "Measuring units per revolution (MUPR)"
— increments per
revolution
— indicates the resolution of the position value per revolution (also:
ST-resolution). The value corresponds to 360°. That is, if a value of 3600 Cts is
parametrized, the encoder outputs the position in 0.1° steps (see equation (2)).
