Functions of Motion Control Interface (MCI)

Via the Motion Control Interface, numerous positioning functions can be addressed by
a PLC directly.
10.2.1

Reference system

In many modes, the Motion Control Interface uses user units [u]. These user units [u]
result from the conversion of the gear factor parameters and the

The same formulas can be used for converting acceleration values from a[Hz/s] to
a[u/s²] and vice versa. In the formulas, replace speeds f[Hz] and f[u/s] by accelera-
tions a[Hz/s] and a[u/s²].
For more details about the reference system, refer to the "Positioning" application man-
ual.
