Error 03.zzz  Examples:
Error 03.128  128 = Error on the gas module
Error 03. 5  5 = 4 + 1  Error on the frequency converter 1 and motor temperature too high
Variants for xxx (for FC1) and yyy (for FC2)
128 64 32 16 8 4 2 1

Error 03.zzz - xxx - yyy  Examples:
Error 03. 5 - 36 - 0  5 = Error on the frequency converter 1 and motor temperature too high -
36 = 32 + 4  Overcurrent recognition on the FC1+ Electronic temperature of
the FC1-
0 = FC2 is ok
Error 03. 32 - 0 - 144  32 = Error on the frequency converter 2 -
0 = FC1 is ok -
144 = 128 + 16  Motor was stopped because of error + FC output current
remains for a long time above the rated current
