3.2.2.76 G226 Reconfigure hardware limit switch

G226 can be used to change the response of the control when traveling on

the direction−dependent hardware limit switches of individual axes.

G226 AXES

AXES Identification of the axes, whose limit switch function should be changed.

0: deactivate limit switch

1: activate normal limit switch function

2: the limit switches effect a limit on the traversing range for the

corresponding axis, but do not cause an error message or a program

termination.

The identification, which is programmed for the axes, defines how the

control should respond to the limit switches of the corresponding axis. If the

limit switches are deactivated, the control does not respond at all to the limit

switches of the axis. In the case of the normal limit switch function, the

control responds by stopping the traversing movement without delay and

terminating a possibly running NC program.

If the identification 2 is programmed, the control responds to the limit

switches, by stopping the traversing movement of the affected axis in this

direction without delay and freezing the position of the axis. The position

remains frozen until the axis should leave the frozen position again in the

opposite direction. During the process, neither an error message is created

nor the program is terminated. This function effects a cutting of profile areas

when traveling on the limit switches.

To reactivate the default setting from the machine constants, G226 can be

programmed without axes.

N10 G226 X0 Limit switch of the X−axis "off".

N90 G226 Activate preset limit switch function for all axes.
