A 20 00 SYS
A slave on the system bus reports a fault; warning is only relevant with the
EM-SYS option.
A 40 00 UDC The DC link voltage has reached the type-dependent minimum value.
A 80 00 WARN2 In
Application Warning Status
367 , a warning is present.
Example: The following warning status is displayed:
A008D Ixt IxtLt Tc PTC
The warning status results from the hexadecimal sum of the warning codes
(0001+0004+0008+0080 = 008D).
The short-term overload (1 s), warning limit heat sink temperature and warning limit
motor temperature warnings are present.
