Is there a message with the alarm number?

This is the Turret, promotion drive generic alarm.

When this alarm occurs please check the Vision/Promotion unit in the electrical cabinet. The digital readout will have the alarm number on the screen.

Also please describe what the machine was doing before the alarm.

Hello, the alarm will appear during a drilling operation of the cycle. This alarm will only appear with a certain tool. The screen reads turret servo alarm, when you check the drive for the code, the error code is not present. The manual does not have this alarm anywhere in the alarm list.

Check the Servo unit alarm history
press mode until you see ALP-h
use up and down arrows to scroll through the history write down the error codes and check again when it happens, if nothing has changed- the promotion unit is the most likely culprit.

It is either giving an erroneous X10.1 alarm signal or X10.6 vpf signal.

These are signals from the promotion unit to the cnc so I wouldn't suspect a cable.

Get your local Doosan agent to check with a replacement promotion unit
