4.18.2 Alarm code output selection (Pr. 76)

At alarm occurrence, its description can be output as a 4-bit digital signal from the open collector output
terminals.The alarm code can be read by a programmable controller, etc., and its corrective action can be shown
on a display, etc.

76 Alarm code output selection
⋅ By setting Pr. 76 to "1" or "2", the alarm code can be output to the output terminals.
⋅ When the setting is "2", an alarm code is output at only alarm occurrence, and during normal operation, the terminals
output the signals assigned to Pr. 190 to Pr. 196 (output terminal function selection).
⋅ The following table indicates alarm codes to be output. (0: output transistor off, 1: output transistor on)

* When Pr. 76 = "2", the output terminals output the signals assigned to Pr. 190 to Pr. 196 .
CAUTION
⋅ When a value other than "0" is set in Pr. 76
When an alarm occurs, the output terminals SU, IPF, OL, FU output the signal in the above table, independently of the Pr. 190 to
Pr. 196 (output terminal function selection) settings. Please be careful when inverter control setting has been made with the output
signals of Pr. 190 to Pr. 196.
