Examples
Writing PROFIdrive process data
In this example, the control word STW1 and the setpoint frequency are written in PROFIdrive
mode. The inputs E0.0 and E0.6 are linked to the Start/Stop bit or to the Acknowledge Fault
bit of the control word STW1.
The process data are written in the cyclical time slice of the S7 (e.g. OB1) at logical address
256 of the frequency converter.
Note
Please note that the way cyclic data are interpreted depends on how the frequency converter
is parameterized (P2050, P0922).
Four bytes of process data are always transferred to the central control unit consistently. Use
of the SFC14 and SFC15 is not necessary.
