This function is used to limit the deviation between two PID output beats(2ms/beats), in
order to suppress the too fast changes of PID output so that stabilizing the inverter operation.

☆
E2.25 and E2.26 respectively corresponds to the maximum of the absolute value of output
deviation when rotating forward and reverse.

Used to select whether to continue computing in the state of PID shutdown. Generally, PID
will stop computing in the state of shutdown.

PID feedback value equal to the given value, the inverter frequency is reduced effectively.
When the inverter frequency feeectively reduced, the frequency converter detection time
interval E2.31 reduced frequency, every time decrease frequency of 0.5Hz, if in the process of
reducing frequency feedback value is less than the given value, inverter speed up directly to the
set value.
E2.30
PID Stop frequency

25Hz
☆
The function code is only used when the automatic frequency reduction (E2.29) is
selected.
The feedback value of the transducer is equal to the given value, the number of PID
detection starts counting, and every PID detection time (E2.31) counts a number of times. When
the count is greater than or equal to the number of PID detection (E2.32), if the frequency of the
inverter frequency is less than PID stop frequency (E2.30), then the frequency converter to slow
down to 0Hz.

☆
The PID Auto-reduced frequency is valid, used to detect the time of frequency decline.

☆
This function is related to PID stop frequency setting, when the set detections time
reached, inverter will slow down then stop.
