Description: Sets the length unit MU per 10 mm set by the user.
For a
linear scale, this establishes a reference between the physical arrangement and the neutral length units LU used
in the drive.
Example, linear scale:
p2503 = 10000 means: 10 mm should be resolved to µm (this means that 1 LU = 1 µm).
Note
When selecting a physical lengt
h unit, the drive automatically preassigns the parameter and it cannot be changed.
The assignment to the grid spacing can be achieved using this for a rotary axis with linear encoder.
