0 to FFFE (in hexadecimal notation)
(When more than FF in hex (255 in decimal), the
number is displayed in order of 163's and 162's, and
161's and 160's places.)

PFC/IGBT error (V-type)
Undervoltage
• Display examples for multiple errors:
Overvoltage (01) + Undervoltage (02) = 03
Undervoltage (02) + Power-sync signal error (08) = 0A
L phase open error (04) + PFC/IGBT error (20) = 24
