Variables and Errors
of the Serial
Communication
8.13.5.1
Basic Variables
V00 (code 00800):
Indication of the inverter type (reading variable).
The reading of this variable allows the inverter type identification. For
the CFW-09 this value is 8, as defined in 8.13.3.7.
V02 (code 00802):
Indication of the inverter state (readingvariable).
- Logical status (byte-high)
- Error code (byte-low)
Where:
Logical status:
EL15 EL14 EL13 EL12 EL11 EL10 EL9 EL8
NOTE!
Values sent and received via serial interface are always integer values. It
is necessary to know the parameter resolution in order to read the correct
value. Ex. Real Current Value = 7.8 A

Received Value = 78.
