Alarm 160

[quatturbo]

Hi all.


The VF-1 here at work one day stopped in the middle of machining, with the alarm "160 low voltage" and has had the alarm ever since.
Now for the life of me, I can't figure out what the problem can be.

Any help would be greatly appreciated.

Thanks

According to an old HAAS manual alarm 160 is

Approx quote "Line voltage to control is too low. Occurs when AC line drops below 190 when wired for 230, or 165 for 208"

thanks gar
..so I should be looking at my incoming voltage, and not the Haas?

Check your actual line voltage and refer to the HAAS manual for setting transformer taps.

If your taps are set correctly for your actual line voltage, then it could be you are at the marginal end of one of the tap ranges. If not you may have an internal HAAS failure.

Be careful inside the electrical cabinet.

With power on check the motor DC bus voltage. Reference your manual.
