Calibration Procedure of the Overload_EN15011 Function Block
1.Find a defined load to put onto the hook with a precisely measured weight in kilogram.
2.Enter the weight at i_stOVLD.dwCalbWght.
3.Enter the nominal load of the crane at i_stOVLD.dwLoadNom.
4.Put i_stOVLD.xCalb to TRUE.
5.Start the movement upwards/forward until the hoist accelerates beyond the desired measurement frequency i_stOVLD.wMeasFreq.
6.q_wStat.5 will be TRUE once calibration is done.
7.Stop the movement and put i_stOVLD.xCalb to FALSE.
8.Compare the output value at q_wActWght with the actual weight of the load.
9.If the calculated weight differs from the real weight change the parameter setting, i.e. wSpdDbnd, wTrqBndCnt, wTrqBndWdth, wSmple and repeat from step 4 to 6.
