Initial process is used by CBL to show the user a power-up of the
converter or a re-initializing of CBL. The user has to acknowledge this
request with the complete flag.

If an error occurs in the converter the status bit error status (RX(n+1)A
is activated. Bit Remote Ready (RX(n+1)B goes inactive. By activating
control bit error reset request (RY(n+1)A you can reset the error
status. This bit is edge sensitive! A 0-1-transition clears the error status.
If the fault in the converter is still active, the error status can't be
cleared!
Initial data setting is used by the PLC program to reset the CBL
interface to CC-Link. Setpoints (written to converter by frequency set
command) will be cleared also with this sequence.

With Initial data setting you can't reset the converter. You only clear
the CC-Link interface!
If drive is controlled with fixed setpoints and the control bits STF or STR
and RL, RM or RH are still be set after Iniital data setting, drive will
start immediately! Using Initial data setting sequence these important
control bits has to be cleared by the user!
