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.
Note: A stop signal from HIM will always stop the motor and clear
the fault regardless of Logic Mask.
• If a RESET push button is present, the N.O. 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.
Important: An overload fault cannot be reset until the Motor
Thermal Usage, parameter 12, value is below 75%. See
Protection and Diagnostics on page 1-11 for further
details.
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 Table 8.A.
