problem with homing X axis

the X axis can be moved manually without a problem , as soon as I start the homing cycle the Z and Y operate as normal but the X does not move and it comes up with ALARM homing error.

This started suddenly prior to this all axis homed properly.

Hi Phil

Have you checked that the X axis homing input is showing low on the F1 screen when the axis is not over the sensor and goes high what the X axis moves over the sensor?

Hi Peter

I checked the input screen and the X axis shows HIGH when I manually move it over the sensor and the light on the sensor goes out when I move it away from the sensor it the sensor light comes on again and still shows High on the F1 screen

Hi Phil

I'm not quite sure what you are saying was the result of your testing.

Are you saying that the X axis input shows High all the time and doesn't change to Low at all?

Cheers

Hi Peter

The input screen shows HIGH on the X axis when I manually move it over the sensor and the light on the sensor goes out and the X axis still shows HIGH on the input screen when I move it away from the sensor the sensor light comes on again and the X axis still shows HIGH. I inverted the X axis with the space bar to show LOW again when I manually move it over the sensor and the light on the sensor goes out and the X axis still shows LOW on the input screen when I move it away from the sensor the sensor light comes on again and the X axis still shows LOW.

when I do a home sequence the X axis triggers the light on the sensor and continues through the sensor with out stopping.

Phil,

Check the wiring, it sounds like a connection has failed. Otherwise the sensor itself is faulty.

Can you disconnect the output near the sensor and check the output changes state in line with the LED. Else ensure that you see a state change at the MASSO input.

Regards,

Arie.
