Note 1. The following errors are not included in the error trace: CPF00, 01, 02, 03, UV1, and UV2.
2. If the PUF fault is already indicated in U2- or U3-, even if the PUF fault is detected again, the fault trace is not updated.
* 1. The minimum unit differs depending on the Inverter capacity. (0.01 A for Inverter of 0.4 kW to 7.5 kW, and 0.1 A for Inverter of 11 kW or more)
* 2. Applicable for G7-Series Inverters with software versions PRG 1039 and later.

Description
Display
The input terminal status when
the previous fault occurred.
The format is the same as for U1-
10.
The output terminal status when
the previous fault occurred. The
format is the same as for U1-11.
The fault history stores the status
of U1-11 and U1-12 before the
fault occurs. Therefore, the fault
output and major fault flag may
not be stored.
The operating status when the
previous fault occurred. The for-
mat is the same as for U1-12.
The fault history stores the status
of U1-11 and U1-12 before the
fault occurs. Therefore, the fault
output and major fault flag may
not be stored.
The operating time when the pre-
vious fault occurred.
Displays the peak hold current
when the last fault occurred.
Displays the frequency value at
the moment the current reached
its peak value when the last fault
occurred.
