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 (reading variable).
- Logical status (byte-high)
- Error code (byte-low)
Where:
Logical status:
E L 1 5 E L 1 4 E L 1 3 E L 1 2 E L 11 E L 1 0
E L 9
E L 8
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.
