11.2.1 Fault
Generation
The following sequence occurs when the protection circuits generate a fault.
•
One or more faults are detected by the control logic.
•
The fault source is latched – only for latched faults.
•
The output stage is disabled.
•
The LED indicates the appropriate fault code.
•
For non-latched faults. When the fault condition is cleared, the drive re-enables
automatically.
Latched faults are cleared by setting the Enable/ input to the disable state or by cycling (off/on)
the Control Power.
NOTE
: The large bus capacitors store substantial energy. To use the control power to reset a
fault, the power should be removed for at least 30 seconds to ensure that the fault resets. Self-
resetting faults disable the drive and do not return it to normal operation until 50-100 ms after
the fault condition clears.
When multiple faults occur, the highest priority fault is reported. After the fault is cleared and the
drive is reset by cycling the enable input, the next highest priority fault that still exists will be
displayed.
