Communication control registers
The address of command word register for communication control is 0x4000.
This register is write-only. The frequency converter is controlled through writing
data into the address. The definition of each bit is shown in table below:

Tab. 13-24: Communication control registers
The address of frequency setting register for communication control is 0x4001.
This register is for read and write. When b1.00 "First frequency setting source"
is set to "5: Given by communication", the frequency converter can be set with
writing data to this address.
If the communication frame check is successful (CRC valid), the frequency con-
verter always accepts the content of the control word. All conflicts (e.g. run
command and stop command active at the same time) are resolved by the appli-
cation functionality (RUN/STOP generator, jog control, ...). This assures that the
frequency converter will always react in the same manner, independent of the
run command source.
