Haas Parameter 64 Z TOOL CHANGE OFFSET
For turret, displacement from home switch to tool 0.
On Vertical mills: For Z-axis; displacement from home switch to tool change position and machine zero. About 4.6 inches, so for an 8192 line encoder this gives: 4.6 x 138718 = 638103
Alternately used for machines with type 4 servo axis pallet changer. It positions the pallet for a pallet change. For example, Z-axis travel on the EC-400 is done by moving the pallet, not the column, and therefore will not affect a tool change. Also, Parameter 64 is generally used during zero return, and that usage is consistent in the EC-400.
