Scaling Of Physical Quantities Of Machine And Setting Data - Siemens SINUMERIK 828D Function Manual

G2: Velocities, setpoint / actual value systems, closed-loop control
7.2 Velocities, traversing ranges, accuracies
Example of rounding:
Computational resolution: 1000 increments/mm
Programmed path: 97.3786 mm
Effective value = 97.379 mm
Example of programming in the
All the linear axes of a machine are to be programmed and traversed within the range of values 0.1 to 1000 μm.
⇒ In order to position accurately to 0.1 μm, the computational resolution must be set to ≥ 10
⇒ MD10200 $MN_INT_INCR_PER_MM = 10000 [incr./mm]:
