 Compared with the software current-limiting function, hardware current-limiting responds more quickly.
Thus, it is suggested that hardware current-limiting function not be cancelled.
5.15 Running History Record (Group PE)
PE.00 Type of latest fault Setting range: Table 5-14-1 [NULL]
PE.01 Output frequency at last fault Setting range: 0~Frequency upper limit [0.00Hz]
PE.02 Reference frequency at last fault Setting range: 0~Frequency upper limit [0.00Hz]
PE.03 Output current at last fault Setting range: 0~2 times of (rated current) [0.0A]
PE.04 DC bus voltage at last fault Setting range: 0~1000V [0V]
Notes:
 If the frequency inverter fails during operation, the PWM output will be blocked immediately to enter the
fault protection state and the fault indicator light TRIP will be flickering. For working conditions during the
time of fault (e.g. output frequency, set frequency, output current, and DC busbar voltage, etc) and the fault
content of recent three times can be found in the function code PE.01~PE.08. Instruction of fault types is
showed in Table 5-14-1:
