pre-condition: denormalization,
Action 1: manual to top，
Wr_Data[0].Wr_Md_Data.Wr_Md_Variable.Wr_MdPg_Variable.e_ExpMotSrVal = SR_NORM_STOP
Wr_Data[0].Wr_Ah_Data.Wr_Ah_Output.s_WrRealtimeDataVal.u1_PosValidAct = 1
Wr_Data[0].Wr_Md_Data.Wr_Md_Output.Wr_MdRo_Output.e_RestrOpMode = -127
Action 2: manual & auto to top
Wr_Data[0].Wr_Md_Data.Wr_Md_Variable.Wr_MdPg_Variable.e_ExpMotSrVal = SR_NORM_STOP
Wr_Data[0].Wr_Ah_Data.Wr_Ah_Output.s_WrRealtimeDataVal.u1_PosValidAct = 1
Wr_Data[0].Wr_Md_Data.Wr_Md_Output.Wr_MdRo_Output.e_RestrOpMode = -127
Action 3: manual down
Wr_Data[0].Wr_Md_Data.Wr_Md_Variable.Wr_MdPg_Variable.e_ExpMotSrVal = SR_POS_ERR
Wr_Data[0].Wr_Ah_Data.Wr_Ah_Output.s_WrRealtimeDataVal.u1_PosValidAct = 0
Wr_Data[0].Wr_Md_Data.Wr_Md_Output.Wr_MdRo_Output.e_RestrOpMode = -95
Comment: It is strange what happen right after Action 3.
What may happen?
