5.3.1.5. State Machine
The state machine describes the device status and the possible control sequence of the frequency
converter. The state transitions can be generated by using the “Control word”. The “Status word”
indicates the current status of the state machine. The modes
INIT, STOP, RUN
and
FAULT
corres-
pond to the actual mode of the Frequency converter

5.3.1.6. Additional Process data in
ProcessData Master -> Slave
The Master can write max. 8 additional setting values to the device with the help of the Process Data.
How these setting values are used is totally dependent on the application in use.
5.3.1.7. Additional Process data out
ProcessData Slave -> Master
The master can read the frequency converter’s actual values using the process data variables. De-
pending on the used application, the contents are either standard or can be selected with a parame-
ter.
