CFW-08 OPTIONS AND ACCESSORIES
They act as follows:
they do not disable the inverter;
they do not disable the fault relay;
they inform in the word the logical status (V02).
Fault types:
E22: longitudinal parity fault (BCC);
E24: parametrization fault (when some of the situations occurs as
indicated in table 5.1 (incompatibility between parameters) or when
there is a parameter change attempt that can not be changed with
running motor).
E25: variable or parameter not existing;
E26: expected values out of allowed limits;
E27: writing attempt in a read only variable or logical command disabled;
E29: serial interface watchdog timeout error.
Note:
If a parity fault is detected during inverter data reception, the message
will be ignored. The same happens when syntax errors occur.
Ex.:
Code values different from the numbers 0,...,9;
Separation character different from “ = “, etc.
