This gain determines the proportion controller’s impact on
feedback deviation. The greater the gain, the faster the impact.
Yet a gain that is too big will cause vibration.
173 1s 0~100s
This parameter is use to set integral controller’s integral time.
When the integral gain is too big, the integral effect will be too
weak to eliminate steady deviation. When the integral gain is
too small, the system vibration frequency will increase, and
therefore the system may be unstable.

This gain determines deviation controller’s impact on the
amount of change of the deviation. Appropriate deviation time
can reduce the overshooting between the proportion controller
and the integral controller.Yet when the deviation time is too
large, system vibration may be induced.

When the deviation value accumulated with the
integral time, an upper limit for deviation
accumulation should be set.

When the feedback pressure satisfies the deviation value for
stopping the machine and the set time (in seconds) for stopping
the machine for detection is reached, the inverter will take the
P.183 step to reduce the frequency.

The pressure command is not entered by an analog input but by
the code used for setting up the operation panel.
