AP.43 PID Unit Gain,
AP.44 PID Unit Scale
Adjusts the scaling (Maximum Value) of the units selected at AP.42 PID Unit
Sel. Can further adjust the unit scaling with AP.44.
AP.45 PID P2-Gain
The PID controller’s gain can be changed using a digital input terminal.
When a terminal is set to 24 (P Gain2) and activated, the gain set in AP.22
and AP.23 can be switched to the gain set in AP.45.
Note
When a digital input (Px) is used to switch to open loop mode, values in [%] are converted to [Hz]
values. The normal PID output, PID OUT is unipolar and is limited by AP.29 (PID Limit Hi) and AP.30 (PID
Limit Lo). A calculation of 100.0% is based on the dr.20 (Max Freq) parameter setting.
