Stop integral adjustment selection when the frequency reaches upper limit or lower limits
1
：
Continue the integral adjustment selection when the frequency reaches high limit or lower limits
For the system need quick response, cancel the continuouse integral adjustment is recommended.
This function can make the close-loop adjustment enter stable stage quickly.
When the close-loop starts, the frequency will accelerate to the preset value set by P7.16 according to Acc time and the inverter
will running with this freuquency in the holding time set by P7.17, then running according to close-lood character, as shown in
Fig4-38.
Note Note Note Note
：
If the function of close-loop preset frequency is not needed, you can set the preset frequency and holding time as 0.
The two function parameter is used for setting PI threshold and hysteresis of zero-frequency operation.
If you set the frequency as 0 Hz, PI threshold of zero-frequency operation will be disabled.
