5.11.12 Fault code output selection
When a fault occurs, the corresponding data can be output as a 4-bit digital signal using via an open
collector output terminal.
The fault code can be read using an input module of programmable controller, etc.
●
Fault codes can be output to the output terminals by setting Pr. 76 "Fault code output selection"
= "1 or 2".
●
When the setting is "2", a fault code is only output when a fault occurs. In normal operation the
terminal outputs the signal assigned in Pr. 191 to Pr. 194 (output terminal function selection).
●
The fault codes that can be output are shown in the table below.
(0: Output transistor OFF, 1: Output transistor ON)
When Pr. 76 = "2", the terminal outputs the signal assigned by Pr. 191 to Pr. 194.
Pr. Name Initial value Setting range Description

NOTE If an error occurs while Pr. 76 ≠ "0", the output terminals SU, IPF, OL, and FU output the signals in
the table above regardless of the settings in Pr. 191 to Pr. 194 (output terminal function selection).
Take caution when controlling the inverter with the output signals set by Pr. 191 to Pr. 194.
