So under normal circumstances, at the beginning of work at a fixed frequency of inverter and start working again after a period of time under load changes and adjustments.

Therefore in the usual situation, starts time the invertor work in the fixed frequency, after starts to work period of time to adjust again according to the load change.

But at system did not throw in to circulate before, the load carry and did not output, can't take out to believe the number.
