Note that when the frequency setting is varied using an analog signal or
alternate ON and OFF depending on that varying speed and the timing of the varying speed due to acceleration/deceleration time setting.
(The output will not alternate ON and OFF when the acceleration/deceleration time setting is "0s".)
REMARKS
The same function may be set to more than one terminal.
When the function is executed, the terminal conducts at the setting of any of "0 to 99", and does not conduct at the setting of
any of "100 to 199".
NOTE
Changing the terminal assignment using Pr.190, Pr.192 (output terminal function selection) may affect the other functions.
Make setting after confirming the function of each terminal.
Do not assign signals which repeat frequent ON/OFF to A, B, and C. Otherwise, the life of the relay contact decreases.

Function
Output when any of the control circuit capacitor, main
Life alarm circuit capacitor and inrush current limit circuit or the
cooling fan approaches the end of its service life.
Fault output 3 Output when a fault occurs due to the internal circuit failure
(power-off signal) or the inverter wiring mistake, etc.
Average current value and maintenance timer value are
Current average value output as pulses.

Maintenance timer
Output when Pr. 503 rises to or above the Pr. 504 setting.
signal
Remote output Output to the terminal when a value is set to the parameter.
Output when an alarm (fan failure or communication error

Output when a fault occurs.
Fault output
The signal output is stopped when the fault is reset.
