FX-Class Inverter Data Stream
8 900-0137-01-00 Rev A
Misc: This is an ASCII expression of an 8-bit byte, displayed in values
ranging from 000 to 255. Each bit represents a different condition. Only
two of the bits are used at this time (see Table 5). Bit 1 indicates an
inverter with greater than 200 Vac output. If this bit is set, then AC input
and output voltages must be multiplied by two and all currents must be
divided by two. Bit 8 indicates the status of the inverter’s AUX output. A
bit value of 1 in the 8
th bit means the AUX output is active.
Warning Codes: This is an ASCII expression of an 8-bit byte, displayed in
values ranging from 000 to 255. Each bit represents a different warning as
shown in Table 6. If more than one warning occurs, the values are
additive. For example, a low AC input voltage and low AC input frequency
would return an ASCII value of 10 (a binary value of 00001010).
Checksum: This is a simple additive checksum of the decimal values of the data stream. Range is 000 to 999.
