3.1 Linear Correction

Parameter	Unit Measure	Range	Description
Front correction (on left)	mm	-9999.9 - 9999.9	Advance space (positive) or delay (negative)of head operation on front of piece
Back correction (on right)	mm	-9999.9 - 9999.9	Advance space (positive) or delay (negative) of head stop on end of piece
Reference speed	mm/s	0 - 99999.9	Speed used as reference for the corrections. Proportional correction varies with the speed change. Setting = 0 Constant correction at any speed

3.2 Cross Correction

Parameter	Unit Measure	Range	Description
IN correction (above)	mm	-9999.9 - 9999.9	Advance (positive) or delay (negative) the head start on the front edge of the slab
OUT correction (below)	mm	-9999.9 - 9999.9	Advance (positive) or delay (negative) the head stop on the back edge of the slab
Reference speed	mm/s	0 - 99999.9	Speed used as reference for corrections The follows speed changes. Setting = 0 Constant correction at any speed
