4.18.2 Fault code output selection (Pr. 76)
⋅ By setting Pr. 76 = "1" or "2", the fault code can be output to the output terminals.
⋅ When the setting is "2", a fault code is output at only fault occurrence, and during normal operation, the terminals
⋅ When the setting is "2", a fault code is output at only fault occurrence, and during normal operation, the terminals
output the signals assigned to Pr. 191 to Pr. 194 (output terminal function selection).
⋅ The following table indicates fault codes to be output. (0: output transistor OFF, 1: output transistor ON)
At fault occurrence, its description can be output as a 4-bit digital signal from the open collector output terminals.
The fault code can be read by a programmable controller, etc., and its corrective action can be shown on a
display, etc.

* When Pr. 76 = "2", the output terminals output the signals assigned to Pr. 191 to Pr. 194 .
CAUTION
⋅ When a value other than "0" is set in Pr. 76
When a fault occurs, the output terminals SU, IPF, OL, FU output the signal in the above table, independently of the Pr. 191 to
Pr. 194 (output terminal function selection) settings. Please be careful when inverter control setting has been made with the output
signals of Pr. 191 to Pr. 194.
