Feedrate override is at0%CNC is reading an axis command (X,Y,Z,...) in a program and giving thecommand to the axis.CNC is reading a dwell command (G04) in a program and is executingthe dwell command.Positioning (G00) to a specified position of a specified axis is notcompleted.Whether positioning is completed or not is checked as the servo positionerror amount. Check it CNC’s diagnostic function as follows:DGN no.300 Position Error > PARAM 1826 In–position widthPosition error amount almost becomes 0, when positioning of an axiscompletes and when the amount becomes within the in–posiiton width,it is assumed that positioning completes and the next block is exected.If position error amount does not become within the in–position width,refer to servo alarm 400, 4n0 and 4n1.Actual feedrate is overridden by the override signals to a programmedfeedrate. Check the override signals using the PMC’s diagnostic function(PMCDGN).G0012#7*FV7#6*FV6#5*FV5#4*FV4#3*FV3#2*FV2#1*FV1#0*FV0G0013*FVn#7*AFV7:Feedrate overrideFeed rate is overridden more finely using the signals below:See MTB’s manual whether this feature is equipped.#6*AFV6#5*AFV5#4*AFV4#3*AFV3#2*AFV2#1*AFV1#0*AFV0*AFVn:2nd feed rate override*FV7*FV0*AFV7*AFV01 1 1 1 1 1 1 11 1 1 1 1 1 1 0:1 0 0 1 1 0 1 1:0 0 0 0 0 0 0 10 0 0 0 0 0 0 00%1%:100%:254%0%1 1 1 1 1 1 1 11 1 1 1 1 1 1 0:1 0 0 1 1 0 1 1:0 0 0 0 0 0 0 10 0 0 0 0 0 0 00%1%:100%:254%0%316
