CNC is reading an axis command (X,Y,Z,...) in a program and giving the
command to the axis.
CNC is reading a dwell command (G04) in a program and is executing
the dwell command.
Positioning (G00) to a specified position of a specified axis is not
completed.
Whether positioning is completed or not is checked as the servo position
error amount. Check it CNC’s diagnostic function as follows:
DGN no.300
Position Error
> PARAM 1826
In−position width
Position error amount almost becomes 0, when positioning of an axis
completes 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 programmed
feedrate. Check the override signals using the PMC’s diagnostic function
(PMCDGN).
