Function Code
PA-21 PID initial value
PA-22 PID initial value holding time
When the AC drive starts up, the PID starts closed-loop algorithm only after the PID output
is fxed to the PID initial value (PA-21) and lasts the time set in PA-22.

Function Code
Maximum deviation between two PID
PA-23
outputs in forward direction
Maximum deviation between two PID
PA-24
outputs in reverse direction
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.
PA-23 and PA-24 respectively correspond to the maximum absolute value of the output
deviation in forward direction and in reverse direction.
