6.11.4 Standstill monitoring
6.11.5 Positioning window
Axes in position
900
Standstill monitoring is effective during operation both with velocity
feedforward and with following error, as soon as the axes have reached the
positioning window.
If the position difference is greater than the value defined in MP1110.x, the
blinking error message STANDSTILL MONITORING IN <AXIS> appears. The
message also appears if, while moving to a position, an overshoot occurs that
is larger than the input value in MP1110.x, or if the axis moves in the opposite
direction when beginning a positioning movement:
In MP1110.x, enter a threshold from which the standstill monitoring should
go into effect.

The positioning window defines the limits within which the control considers
a position to have been reached. After the position has been reached, the
control begins running the next block. The position controller can correct a
disturbance inside this window without activating the "Return to the Contour"
function.
In MP1030.x, define the size of the positioning window.

Input:
0.0001 to 2.0000 [mm]
Once the axes have moved into the positioning window, the corresponding
bits are set in W1026/W1104. This also applies to the status after the machine
control voltage is switched on. Axes that are not used are considered to be in
position.
The NC resets the bits as soon as you start a positioning movement or
traverse the reference marks.
In the Electronic Handwheel mode of operation the bit for the current
handwheel axis is reset.
W1026/W1104 is not set for contours that can be machined with constant
surface speed.
