When feedback pressure is larger than high pressure and reach detecting point(F7.12),
inverter will stop outputting, turn into sleeping state immediately，and display “EoPP”.
When output frequency is lower then that F7.21 have set and keep F7.22 delay, the inverter
will stop output , turn into sleeping state, and display “EoPP”.
Remark:When any parameter is 0, the sleeping function is ineffective.

In positive acting mode, when feedback value is lower than the set value of F7.23 and keep
F7.24 delay, the inverter relieve sleeping status and start to output again.

Set the PID effective tuning range, improve the controllability of motor acceleration and
deceleration outside the range，the acceleration and deceleration time is subject to F0.08/F0.09，
and the time within the range can be seen by setting parameters F9.02, F9.03.
