NO DAC OUTPUT

Post by Scott Pancheau » Sun Dec 06, 2020 12:58 am

Had lathe running up through tuning motors process. Left sit a couple of months. When I started it up again I am not getting DAC outputs on the X and Z axis drives. The Analog screen shows output but there is no voltage. The spindle DAC works like it should. I tried the non used DACS just to see if they would output and none of them would. I cycled the power several times to the KFLOP and it shows the normal start up LED lights. Is there something I can try to do?
Thanks,
Scott

Hi Scott,

Does the Enabled LED on Kanalog come on?

If the Analog Screen shows voltage there should be voltage.

Disconnect everything from Kanalog. Cycle power. Command DAC0=2000 on the console. What voltage do you measure on DAC0 with a voltmeter?

Post your Config, Step Response, and Filters Screens.

Thank you Tom. It was user error. I forgot that the top of the screw terms for Dac output seem to have a coating that is non conductive. The Dac outputs were working all along. The power supply for the servo system had a blown fuse. Sorry for the false alarm.
