FA-23
Maximum deviation between two PID
outputs in forward direction
0.00%–100.00% 1.00%
FA-24
Maximum deviation between two PID
outputs in reverse direction
0.00%–100.00% 1.00%
This function is used to limit the deviation between two PID outputs (2 ms per PID output) to
suppress the rapid change of PID output and stabilize the running of the AC drive.
FA-23 and FA-24 respectively correspond to the maximum absolute value of the output
deviation in forward direction and in reverse direction.
