5.15 Running History Record (Group PE)
PE.00 Type of latest fault
Range: Table 5-14-1【NULL】
PE.01 Output frequency at last fault
Range: 0~Frequency upper limit【0.00Hz】
PE.02 Reference frequency at last fault
Range: 0~Frequency upper limit【0.00Hz】
PE.03 Output current at last fault
Range: 0~2 times of rated current【0.0A】
PE.04 DC bus voltage at last fault
Range: 0~1000V【0V】
Note:
 If faults occur during operating, the inverter stops PWM output immediately, and
accesses to the fault protective state. Moreover, the fault indicator “TRIP” is lit up
and flickered. The operating condition (such as output frequency, reference
frequency, output current, and DC bus voltage etc.) of latest fault and types of the
last 3 faults, could see in PE.01~PE.08. Descriptions of faults are shown in Table
5-14-1:
