We had that cable replaced ½ year ago. I spoke with fadal service and they told to adjust loop gain / balance from amp card.
DC Amplifier
Adjustment
1) Enter the following program:
a. X-4. Y-4. Z-4. G1 F150. M49,M91.
b. X4.Y4.Z4.
c. M99P1
2) Press Auto, to start the program running.
Easy.
3) At the amplifier to be adjusted, use a small screwdriver and turn the SIG2
potentiometer until the monitor’s display of the appropriate axis reads the
following error: 595 - inch ballscrew / 302 - metric ballscrew.
We have inch ballscrews. AMP card didnt have SIG2 pot but there was SIG pot. It took amazingly many turns to reach numbers around 600
4) Press the SLIDE HOLD button on the keypad and adjust the balance of the
amplifier to read between 0 - 1.
Here is the problem, balance reading won't stay still to be adjusted, it bounces around from -6 to 14 constantly.
5) Press the START button on the keypad and the program will start again.
Verify that the following error is still 595 or 302.
Wont get stable reading here as well, reading is bouncing 550-650 when X is moving  |
