Hello, It's been awhile. I've been waiting for a servo to come back from CNCservo.com. Don't get me started on that! Anyway, I bought this machine in October at a plant closing auction. When I would try to jog it, (any axis) I would get a motor overload alarm, and it e-stops itself. The motor is trying to move since the column would lower an inch or two. I spoke with a technician/employee at the acution and he said he had swapped boards around and felt like it was in the Z motor so he was going to send it for repair, but his boss said don't spend the money, the plant is closing. I removed the motor and a local motor shop shop sent it to Cncservo.com. They rewound the motor, lost my resolver and cover, I got to pay for a new resolver, they tested the motor and sent it back.
I finally got around to running wire to the machine/phase converter. Tested voltages etc. Pressed CNC power, got power to the control. Tried to jog (z), column went "up" an inch or two, "error #3 motor overload", did that several times, and nearly got it to the CS position. I'm able to rotate the ball screw by hand to raise/lower the column. I have blinking led's on the control boards, and solid red lights on the servo amps. I'm able to see that the LED's on the amps briefly turn green before it e-stops.
Then next thing I'm going to try is swapping the boards and see if I can get the problem to move.
Could it be there is a problem with a different axis, but Z is the 1st one it tries to move so it is the 1st alarm to show-up? Obviously, the motor is doing something since it is able to get the colum to move when I press Jog. It's seems like a "runaway" situation, but it stops itself.
Yes, these are glentek servos!
Thanks in advance.
