10.2 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
No. of pole pairs 373.

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 acceler
a-
tions a[Hz/s] and a[u/s²].
For more details about the reference system, refer to the “Positioning” application man-
ual.
10.2.2 Modes of operation
In Override Modes Of Operation 1454, you can define the operation mode of the fre-
quency inverter.
The available options depend on the set frequency inverter configuration.
Available values for Override Modes Of Operation 1454 in configurations of the fre-
quency inverter with position control (Parameter Configuration 30 = x40):
