Samsung QSA error

Samsung QSA error | 8 June, 2017

We have a Samsung that we have replaced all the amps and are still getting the Z axis motor alarm failure. On the “Position Window” before and after we try to “Home” the machine, the values for “Z-Axis” for all three heads prior to the “Home” action are all in the 40.188 to 40.190 range. Once the “Home” button is pushed, the values on heads #2 & #3 go from zero to 40.188 and 40.190 respectively then stop while the value for head #1 cycles up past 131.3 and then the “Motor alarm” message comes up.

What causes this value to rise? As stated before we have replaced all three head Z-axis amps with no change. Appreciate any help.

So what your telling me is kind of vague.

Does the machine home and go to the front left corner of the machine? If it does....this could be a quad align problem....meaning dirt on the lens or so-forth.

You should watch the heads homing in the z-axis. It sounds like head 1 has an issue. Is it moving at all? Does it move down and up?

The machine does not move to the home position. Once we hit the "Home" button all three heads will move up to the "Home" position but then 5 to 10 seconds later the following error pops up "Error 1531 - Z Axis motor alarm" before any "xy" movement is seen. In this short sequence is where we see the numbers on the "Position Window" scroll up. For a split second we observe a alarm #2 light indicator on the head #1 servo amp before machine alarms. Simon

Yes. All amps were properly programmed and tested with another Samsung machine. In addition head #1 Z-axis motor was also swapped out.
