Overview
This chapter describes the fault diagnostics of the MV SMC Flex controller.
Further, this section describes the conditions that cause various faults to occur.
Protection Programming
Many of the protective features available with the SMC Flex controller can be
enabled and adjusted through the programming parameters provided. For further
details on programming, Refer to
Motor Protection on page 84 of Chapter 4
Fault Display
The SMC Flex controller comes equipped with a built-in three-line, 16-character
LCD. The LCD displays the fault message on the first line, the fault code on the
second line, and the fault description on the third line.

TIP
The fault display will remain active as long as control power is applied. If
control power is cycled, the fault will be cleared, the controller will re-initialize,
and the display will show a status of “Stopped”.
TIP
You can hit ESC to get to another programming/diagnostic list, but the SMC
Flex will still be in a faulted state.
IMPORTANT
Resetting a fault will not correct the cause of the fault condition. Corrective
action must be taken before resetting the fault.
