Tab. 14-24: Communication control register (0x7F00)
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.
