PA.21
Initial value of PID
Default
0 %
Setting range
0.0 % - 100.0 %
PA.22
Initial value of delaying PID
Default
0.00 s
Setting range
0.00 s – 650.00 s
When the inverter starts, the PID will start the closed loop algorithm only after the
PID output is stabilized to the PID value (PA.21) and this delay time is set in PA.22.

PA.23
Maximum deviation between two
PID outputs in the forward
direction
Default
1.00 %
Setting range
0.0 % - 100.0 %
PA.24
Maximum deviation between two
PID outputs in the backward
direction
Default
1.00 %
Setting range
0.0 % - 100.0 %
This function serves to limit the variance between two PID outputs (2 ms to the PID
output) which suppress the fast change of the PID output and stabilize the AC motor
operation.
PA.23 and PA.24 correspond to the maximum absolute value of the output deviation in the
forward and reverse directions.
