MICRO SERIES FAULT HISTORY
Parameter 70 — FAULT HISTORY stores the last eight faults that
tripped the drive. The FAULT HISTORY indicates the number of
the fault (number 1 is the most recent fault), the fault message,
and the status of the drive at the time of the fault. An example is
shown below:
FAULT DESCRIPTION
OUTPUT Output Transistor fault. Output current exceeded 200%.
May be ground fault or short circuit.
LO VOLTS Low DC Bus Voltage fault. DC bus voltage dropped below 60%
May be low line voltage.
HI VOLTS High DC Bus Voltage fault. DC Bus voltage exceeded 120%.
May be overhauling load .
HI TEMP High Temperature fault. Heatsink or ambient temperature
too high.
OVERLOAD Current Overload fault. Output current exceeded 100% for
too long. VFD may be undersized.
PWR TRAN Power Transient fault.
PWR SAG Power Sag fault: New control board installed. Perform
factory reset using Parameter 65.
LANGUAGE Language EEPROM fault.
EXTERNAL External fault: TB-130 activated (Parameter 50).
DB ERROR Dynamic Brake fault. DB Resistors overloaded.
CONTROL Control Board fault. New solfware installed. Perform factory
reset using Parameter 65.
INTERNAL Internal fault
INTERN (#) Internal fault.
