The state machine describes the device status and the possible control sequence of the frequency
converter. The state transitions can be generated by using “control word” parameter. The “status word”
parameter indicates the current status of the state machine. The modes INIT, STOP, RUN and FAULT
(see figure 7-1) correspond to the actual mode of the Frequency converter.
DISABLE (Bit6=1
) is one value of the “status word”.
Bit0=0 is one value of the “control word”.
