Alarm code output selection

At alarm occurrence, its description can be output as a 4-bit digital signal from determined 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.

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 func-
tion selection".
The following table indicates alarm codes to be output. (0: output transistor off, 1: output tran-
sistor on)

Tab. 6-99: Alarm codes
When Pr. 76 = "2", the output terminals output the signals assigned to Pr. 190 to Pr. 196.
.
NOTE 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.
