Hello All,
I have been a silent follower of this community for a while and this will be my first post. I recently purchased a 2000 Arrow-500 vmc and have been running it problem free for quite a while. Earlier today, however, upon startup the following error popped up: Alarm 44-52 X-axis encoder error. (Image attached)
The sequence of events were as follows: Initial boot was successful, after attempting to power up the servos, low air-pressure error was thrown. This was a user error since I hadn't realized the compressor had been shut off by someone. After having remedied that, servo power up was attempted and Alarm 44-52 was thrown. At this point, perhaps out of ignorance, I decided to power-cycle the machine completely thinking the low-air pressure alarm had something to do with it. Second attempt at servo power up successful after system reboot. Here is where things got interesting: I attempt to home the machine at which point it retracts slowly in Z as expected and then RAPIDS in X (the correct direction, towards home) until it hits the mechanical hardstop. Alarm 44-52 x-axis encoder error was back (with a bang.)
Having read two previous posts with similar issues, I attempted to reseat the encoder connector on the x-axis motor, servo board, x-axis drive, and the servo board in its entirety to no avail. Every subsequent attempt to boot the machine results in the alarm described above before the control gets to the home-screen.
The table is currently on the home-switch and having tried (not very hard) to move it off manually I was unable to budge it.
The machine is equipped with the blue Vickers drives and I believe has glass-scales all around (I can see the one on Z) but after having removed the guard over the X-axis motor in hopes to gain access to the ball-screw in order to rotate it to get the table off the switch, was unable to see the scale in X. That being said, I'm not sure where they are or would be located (where to look) on this particular machine.
Any thoughts or similar past experiences (hopefully with quick solutions :) ) would greatly be appreciated since at this point I'm a little stumped.
Many thanks in advance,
ih
