94 194 Y94 Alarm output 2
Output when the inverter’s protective function is
activated to stop the output (major fault).
Continue outputting the signal during inverter reset and
stop outputting after reset is cancelled. (Note 9, 10, 11)
95 195 Y95 Capacitor life alarm output Refer to Pr. 503 and Pr. 504 (capacitor life alarm) Pr. 503, Pr. 504
98 198 LF Minor fault output
Output when a minor 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).
Stops output when reset is on.
9999 No function
Note: 1. Under encoder feedback control (when the FR-A5AP option is fitted), the operations of the up-to-frequency
SU and frequency detection FU, FU2, FU3 are as follows:SU, FU: The actual speed (frequency) provided
by the encoder feedback signal is output at or above the frequency specified for detection.
FU2, FU3: The inverter output frequency is output at or above the frequency specified for detection.
2. 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 "0s".)
3. This signal is output when "5" is set in Pr. 79 "operation mode selection" and the external operation mode is
selected (the inverter goes into the programmed mode).
4. The same function may be set to more than one terminal.
5. 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.
6. Pr. 190 to Pr. 195 do not function if the values set are other than the above.
7. 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.
8. The output assignment of the RUN terminal and alarm output relay conforms to the above setting
independently of Pr. 76.
9. When making a power-on reset, the alarm output 2 signal "Y94" is turned off as soon as power is turned
off.
10. The alarm output 2 signal "Y94" can not be assigned to the extended assignment terminal of the option unit
(FR-A5AY, FR-A5AR, FR-A5NR).
11. When parameters are copied to the inverter without this signal, the changed settings of output terminal
function selection parameters (Pr. 190 to Pr. 195) become "9999 (no function)"
