NAMUR message word
Fault word according to the VIK-NAMUR definition (MELD_NAMUR)
Bit Significance
P no.
0 1 = converter signals a fault
p2051[5] = r3113
1 1 = line fault: phase failure or inadmissible voltage
2 1 = DC link overvoltage
3 1 = power unit fault, e.g. overcurrent or overtemperature
4 1 = converter overtemperature
5 1 = ground fault/phase fault in the motor cable or in the motor
6 1 = motor overload
7 1 = communication error to the higher-level control system
8 1 = fault in a safety-relevant monitoring channel
10 1 = fault in the internal converter communication
11 1 = line fault
15 1 = other fault

Parameter channel
Structure of the parameter channel
The parameter channel consists of four words. The 1st and 2nd words transfer the parameter
number, index and the type of task (read or write). The 3rd and 4th words contain the
parameter content. The parameter contents can be 16-bit values (such as baud rate) or 32-bit
values (e.g. CO parameters).
Bit 11 in the 1st word is reserved and is always assigned 0.
You can find application examples relating to the parameter channel at the end of this
section.
