While PID feedback reaches or exceeds the setting value, if any output
terminals［F-30～F-32］is set as “15”（PID feedback quantity upper limit
alarming, it outputs alarm signal; This parameter is defined as percentage of
the largest range of the sensor that the PID feedback quantity accounts for.
While PID feedback reaches or under the setting value, if any output
terminals［F-30～F-32］is set as “16”（PID feedback quantity upper limit
alarming, it outputs reaching signal; This parameter is defined as percentage
of the largest range of the sensor that the PID feedback quantity accounts for.
This function is only valid in using the constant PID control.

When the frequency inverter is in the PID control mode, this function is
valid; If the detection feedback signal is less than [H-28], the sensor is
deemed to be open circuit. At this moment ,if any one of output terminal ［F-30～
F-32］is set as “17” (sensor disconnect), the output signal is valid; This
parameter is defined as the percentage of the sensor maximum range that the
feedback signal accounts for.
