4.2.54 Control gain switching function (CAS)
The control gain switching function allows you to set and switch
between two types of gains and time constants for the speed control
system (with proportional and integral compensations) when the V/F
characteristic curve selection is the sensorless vector control,
0Hz-range sensorless vector control, or vector control with sensor.
To use this function, assign function "26" (CAS: control gain setting) to
one of the terminal [1] to [8] functions (C001 to C008).
When the CAS terminal is turned off, the gain settings "H050", "H250", "H051", "H251", "H052", and "H252" are
selected. When the CAS terminal is turned on, the gain settings "H070", "H071", and "H072" are selected.
If function "26" (CAS: control gain setting) is not assigned to any intelligent input terminal, the same gain settings as
those selected when the CAS terminal is off are selected.

4.2.55 P/PI switching function (PPI)
The P/PI switching function allows you to switch the control
(compensation) mode of the speed control system between the
proportional integrated compensation and proportional compensation
modes when the V/F characteristic curve selection is the sensorless
vector control, 0Hz-range sensorless vector control, or vector control
with sensor.
To use this function, assign function "43" (PPI: P/PI mode selection) to one
of the terminal [1] to [8] functions (C001 to C008).
When the PPI terminal is turned off, the proportional integrated compensation mode is selected. When the PPI
terminal is turned on, the proportional compensation mode is selected.
If function "43" (PPI: P/PI mode selection) is not assigned to any intelligent input terminal, the proportional integrated
compensation mode is selected.
