homing don't work when "Dir.positive" is check

[steftt]

Good morning
I encounter a problem with the Z axis homing settings
all the axes do homing well, except the Z axis which does not stop, it is set to "Dir.positive" because it must go to find the reference point at the top
I tried everything and it's the same for all the other axes, if I set them to "Dir.positive" it does not stop when approaching the sensor, (NC inductive sensor mounted in series)
I tried to do the test by approaching a metal part while the axes are looking for homing, I have a message in the DIAG window stating that the home sensor is triggered, but the axis does not stop!
do you know what the problem could be?
thanks
