The actual alarm 411 reads 'The contents of the error register of the X axis is larger than the value allowed while the machine is moving".
It is actually following error, it can be caused on a slant bed lathe when the X axis counterbalance requires attention, or something has tightened up on the axis to cause the following error.
I have had to tweak the parameters in some cases as the machine ages.
RPDFX for e.g. Rapid traverse rate.
