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 to 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 terminal A, B, C. Otherwise, the life of the relay contact
decreases.
Function assignment of external terminal and control
Function
Output when a fault occurs due to the internal circuit failure
of the inverter wiring mistake.
Average current value and maintenance timer value are
output as pulses.
The signal can not be set in Pr. 192 A,B,C terminal function
selection .
Output when Pr. 503 rises to or above the Pr. 504 setting.
Output to the terminal when a value is set to the parameter.
Output when an alarm (fan failure or communication error
warning) occurs.
Output when the fault occurs.
The signal output is stopped when the fault is reset.
