I've searched this forum in the past for all of my Haas woes, and found all the answers I've been looking for. This new one has me stumped.
Yesterday morning I pressed the green power up button and the hydraulics kicked on, not after the reset button was pressed to clear the 102 alarm. I didn't think this was right. I pressed the reset button, but instead of cleaning the 102 alarm, a 161 alarm came up. I could clear the 161 alarm, but everytime I cleared the 102, both came back up. The E-stop also doesn't kill the hydraulics.
I did entertain the idea of swapping drive cards. The 161 error was always X axis. I swapped cables coming from the controller to the cards thinking one was bad. Still X error. I even switched the X & Z motor cables at the plugs (I know how bad of an idea that was) but it was still a 161 X error.
So what I'm thinking is a transistor failed in the safety
circuit, allowing the hydraulics and the servos to power up immediately. The 161 alarm us just a byproduct of this.
Has anyone had this issue? If so, what is the location if the typical culprit?
HL-2 DC drives 161 alarm at start up.
