corresponding addresses of iG5A are acquired by the following
formula. [Modbus address] = [iG5A address] - 1 Modbus word output
area is from 0x40000. Therefore, [0x0005] is to be [0x40004]. Here
D0000 is assigned to 0x40004, which means D0 data value is sent to
ref. Freq. area. In the previous slide, 4 words are to be sent.
Therefore, D0 for Reference Frequency D1 for Run command (D1.0 bit
is on iG5A stop; D1.1 bit is on iG5A forward run, etc). D2 for ACC

Right-mouse click Select [Channel 2] and click [Start] then you
will see its communication frame. Even though XGB has no RTC, but
it shows time stamp when the transmission/reception frame pass
through the comm. port. This is important because in 1:N comm. In
RS-485 (half-duplex) system, transmission and reception frame
should be interlocked. And a user could know the best possible
conditional flag to send each frame by this time stamp. Website:
