Function assignment of external terminals
Parameter
6 - 100
Note that when the frequency setting is varied using an analog signal or the digital dial of
the operation panel, the output of the SU (up to frequency) signal may 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".)

Life alarm
Output when any of the con-
trol circuit capacitor, main cir-
cuit capacitor and inrush
current limit circuit or the
cooling fan approaches the
end of its service life.

Alarm output 3 (power-off signal)
Output when an error occurs
due to the circuit failure or
connection alarm of the
inverter.

Current average value monitor
signal
Average current value and
maintenance timer value are
output as pulses. The signal
can not be set in Pr. 192
"ABC terminal function selec-
tion".

Output when Pr. 503 rises to
or above the Pr. 504 setting.

Minor fault output
Output when a minor fault
(fan failure or communication
error warning) occurs.
Pr. 121, Pr. 244

ALM
Alarm output
Output when the inverter's
protective function is acti-
vated to stop the output
(major fault). The signal out-
put is stopped when a reset
turns on.

Output terminal function assignment (3)
NOTES
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".
Changing the terminal assignment using Pr. 190, Pr. 192 or Pr. 197 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.
Refer to section 3.4 for the common terminal of each terminal.
