Mitsubishi Electric FR-F820-00077 Instruction Manual page 409

Parameters
Do not assign signals which repeat frequently between ON and OFF to terminals A1B1C1 or
A2B2C2. The life of the relay contacts will be shortened.
Adjusting the output terminal response level (Pr. 289)
The response level of the output terminals can be delayed in a range of 5 to 50 ms. (Operation example
for the RUN signal.)
RUN
Pr. 289 = 9999
RUN
Pr. 289 ≠ 9999
NOTES When Pr. 157 "OL signal output timer" is set for the Overload warning (OL) signal output, the OL
signal is output when the set time of (Pr. 157 + Pr. 289) elapses.
For the output signal and the fault code output (on page 5-249) used in the PLC function (on page
5-439), the Pr. 289 setting is invalid (no filter).
