P106 PID Control Mode
With this function, the inverter can be used to control processes such as flow, air
volume or pressure.
When the automatic tuning through PID control starts,
the inverter will automatically drive the motor within the
range of uppter/lower frequency limit. Therefore, do not
approach the unit.
Failure to do so may result in injury.
“PID operation mode select” and “switch setting for automatic tuning function”
can be performed.

Either “derivative-precedence type” or “proportional-derivative precedence
type” PID control can be selected.
Derivative precedence type PID control: generally speaking, when the setting
value (SP) is changed, output
variation will increase and
convergence will speed up.
