This setting allows the operator to select how the control interprets an F value (feedrate) that does not contain a decimal point. (It is recommended that you always use a decimal point.) This setting helps operators run programs developed on a control other than Haas. For example F12 becomes:

  • 0.0012 units/minute with Setting 77 OFF
  • 12.0 units/minute with Setting 77 ON

There are 5 feedrate settings. This chart shows the effect of each setting on a given F10 address.

INCH   MILLIMETER
DEFAULT (.0001)   DEFAULT (.001)
INTEGER F1 = F1   INTEGER F1 = F1
.1 F10 = F1.   .1 F10 = F1.
.01 F10 = F.1   .01 F10 = F.1
.001 F10 = F.01   .001 F10 = F.01
.0001 F10 = F.001   .0001 F10 = F.001

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
