Example: CNC-controlled, translatory axis with SERCOS Drive

The linear axis moves by 1 mm per motor revolution. The position data in the drive are weighted for translatory movements:

Weighting factor: S-0-0077 = 1

Weighting exponent: S-0-0078 = -7

The path resolution of the measuring system is therefore:

A path motion of 1 mm per motor revolution results in a feedrate constant of:

A translatory weighting is also used for velocity data:

Weighting factor: S-0-045 = 1

Weighting exponent: S-0-046 = -4

The weighting factor for velocity is therefore:

Manipulated variable scaling is therefore:
