Refer to Pr. 500 to Pr. 516 (advanced PID
control). (Page 145)
(Setting may be made for the NA and EC versions
only.)
Pr. 500 to
Pr. 516
98 198 LF Minor fault output
Output when a light fault (fan fault or
communication error alarm) occurs.
Pr. 121, Pr. 244
99 199 ABC Alarm output
Output when the inverter's protective function is
activated to stop the output (major fault).
9999
No function
0 to 99: Positive logic
100 to 199: Negative logic
Note: 1. When the frequency setting is varied with the analog signal or the key of the operation
panel, note that the output of the SU (up-to-frequency) signal may alternate between ON and OFF
due to that varying speed and the timing of the varying speed dependent on the
acceleration/deceleration time setting.
(Such alternation will not take place when the acceleration/deceleration time setting is "0 s".)
2. The same function may be set to more than one terminal.
3. When the function is activated, the terminal conducts with the settings of 0 to 99 and does not
conduct with the settings of 100 to 199.
4. Pr. 190 to Pr. 195 do not function if the values set are other than the above.
5. When Pr. 76 = 1 or 3, the output signals of the SU, IPF, OL and FU output terminals conform to
Pr. 76. When an inverter alarm occurs, the signal outputs are switched over to alarm code
outputs.
6. The output assignment of the RUN terminal and alarm output relay conforms to the above setting
independently of Pr. 76.
