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 diagnostic function as follows:
DGN no.300
Position Error
> PARAM 1826
Inposition width
Position error amount almost becomes 0, when positioning of an axis
completes and when the amount becomes within the inposiiton width,
it is assumed that positioning completes and the next block is exected.
If position error amount does not become within the inposition 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 PMCs diagnostic function
(PMCDGN).
