    Bridgeport Interact 412 w Heidenhain 151 Controller stops mid program

    Hello all,

    First time posting. Spent a couple of days looking for a thread that might have an answer to our challenge. Our Bridgeport Interact 412 w a Heidenhain 151 Controller starts up fine. Had been sitting for a while, when we would run a program we would get a gross positioning error. Problem was the ways weren't getting enough lube. sorted it out. Don't get the error message anymore. Now the machine starts up fine, but while running a program, it will randomly stop moving. Spindle still running coolant flowing. During troubleshooting, out of frustration our machinist whacked the table with a soft mallet. Low and behold it started moving. It will randomly stop in X, Y or Z axis. Whack the table, the program will continue in what ever direction it was moving. We're baffled.

    Looking for some insight.

    Alan

    Assuming the drives are DC it sounds like there is a brush sticking or worn out in a servo motor, probably the "X" axis. Depending on the program one faulty axis will stop the others from running because the controller will be waiting for the faulty axis to move. Dave

    Update: Pulled the X-Axis motor. Removed the motor brushes one at a time. Two had so much carbon dust, hard to pull them out. All brushes are worn a little over 3mm. New ones are a little over 14mm. (Called a place that has some, they measured length.) Reinstalled the motor. No change. Still acts the same. Moving on to the Y-Axis.

    The problem is on the drive offsets. Enter the code 75368 and accept the values. This is memory based offset correction. Alternatively you can adjust the offset from the drives. Put the display to LAG mode and in the manual mode you can see the offset on the axis display. Adjust the offset potentiometer until the values are 0,000.

    Make sure your machine is getting enough lube.
