- 239 -
5022
Distance (L) from reference tool tip position to the reference measurement
surface
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm, inch (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] 9 digit of minimum unit of data (refer to standard parameter setting
table (A) )
(When the increment system is IS-B, -999999.999 to +999999.999)
For each axis, this parameter sets the distance from the reference tool
tip position to the reference measurement surface when the machine is
at the machine zero point.
