A W-axis DCC move was attempted, but the W-axis would not move. Possible causes are:
There is insufficient air pressure.
The drive nut is too tight.
There is a counter failure.
What you should do:
To clear the error, power the MP down.
Power the MP back up.
Check the air pressure to make sure it is set correctly.
Check the drive nut, and loosen it if necessary.
If the error reoccurs, contact your Giddings & Lewis service representative.
