From the following data table we find that the addressing for node 3 frequency is register
40102. We place 3000 (frequency x 100) into that register.

The register for node 3 status command (from the above table) is 40103. From the table below
we determine that for the inverter to run in
reverse
using
#2 acc/dec
pattern we must place a
C009 (hex) into that register.

NOTE:
If the last global write to a node includes a 1 in either the Global Input Command
Enable (bit F) or the Global Frequency Command Enable (bit E), then the inverter at that
node address will not accept any frequency or status commands from a regular write
command (MSTR function 1) until these bits are changed to a 0 and the global write
command is resent. Regular read commands (MSTR function 2) are also overriden while
the Global write command bits are set.
