Diagnostics

Overview

This chapter describes the fault diagnostics of the 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 the
Motor Protection section in Chapter 4, Programming.

Fault Display

The SMC-Flex controller comes equipped with a built-in three-line,
16-character LCD. The LCD displays the unit has faulted on the first
line, the fault number on the second line, and the fault code on the
third line.

Figure 8.1 Fault Display

Note: 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.”

Note: You can press 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.
