76 Alarm code output selection
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 146)
(1) Alarm code output function
⋅ 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)
Operation Panel
Other than the above
* When Pr. 76 = "2", the output terminals output the signals assigned to Pr. 190 to Pr. 196 .
CAUTION
⋅ Refer to page 189 for details of alarm code.
⋅ 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 outut
signals of Pr. 190 to Pr. 196.
