The parameter Encoder Sub Mask (absolute range maximum value) indicates how many bits of the
maximum encoder value are single-turn bits. The default setting is 20 (and therefore 12 multi-turn bits). The
calculation is based on the following equation.
Further calculation example with 13 single-turn bits and 8 multi-turn bits.

Scaling factor
The scaling factor can be changed by selecting "Axis 1_Enc" and tab Parameter in the NC (see Setting the
Scaling Factor). The value can be calculated with the formulas specified below. The calculation is based on
the assumption that one revolution corresponds to 360°.
The number of single-turn bits is taken into account in the calculation of the scaling factor. As indicated
above, the default setting for the EL72x1-0010 is 20 single-turn bits. This value is also used for calculating
the scaling factor. If the single-turn bit value is changed, the scaling factor must be adjusted.
