MC1000 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:

Low DC Bus Voltage fault: DC bus voltage
dropped below 60%. May be low line voltage.
High DC Bus Voltage fault: DC bus voltage
exceeded 120%. May be overhauling load.
High Temperature fault: Heatsink or ambient
temperature too high.
Current Overload fault: Output current exceeded
100% for too long. VFD may be undersized.
Power Transient fault.
Power Sag fault: New control board installed.
Perform factory reset using Parameter 65.
Language EEPROM fault.
External fault: TB-13D activated (Parameter 50).
Dynamic Brake fault: DB Resistors overloaded.
Control Board fault: New software installed.
Perform factory reset using Parameter 65.
Internal fault.
Internal fault.
In the example above, the second fault is being viewed, which is an
