Clear Fault
You can clear a fault using any of several methods:
•
Program the SMC Flex controller for a Clear Fault, which can be found in
Main Menu/Diagnostics/Faults.
•
If a human interface module is connected to the controller, press the Stop
button.
•
If a RESET push button is present, the NO push button auxiliary contact
can be connected to Option Input #2 (terminal 15). Option Input #2 must
be programmed for Clear Fault.
•
Cycle control power to the SMC Flex controller.
Fault Buffer
The SMC Flex controller stores in memory the five most recent faults. Display
the fault buffer by selecting the View Faults Queue and scrolling through the
fault buffer parameters. The information is stored as fault codes and fault
descriptions. A fault code cross-reference is provided in
.
TIP
A stop signal from the HIM will always stop the motor and clear the
fault regardless of Logic Mask configuration (Logic Mask, parameter
#87, equals ø).
IMPORTANT
An overload fault cannot be reset until the Motor Thermal Usage,
parameter 12, value is below 75%. Refer to
for further details.
