Referencing status
By setting a new actual value in the machine coordinate system, the referencing status of the
machine axis is reset:
DB31, ... DBX60.4/.5 = 0 (referenced / synchronized measuring system 1/2)
It is recommended that PRESETON only be used for axes that do not require a reference point.
To restore the original machine coordinate system, the measuring system of the machine axis
must be referenced again, e.g. through active referencing from the part program (G74).
CAUTION
Loss of the referencing status
By setting a new actual value in the machine coordinate system with PRESETON, the
referencing status of the machine axis is reset to "not referenced/synchronized".
Programming
Syntax
PRESETON(<axis_1>, <value_1> [, <axis_2>, <value_2>, ... <axis_8>,
<value_8>])
Meaning
PRESETON: Set actual value with loss of the referencing status
Preprocessing
stop:
yes
Alone in the block: yes
<axis_x>: Machine axis name
Type: AXIS
Value range: Machine axis names defined in the channel
<value_x>: New actual value of the machine axis in the machine coordinate system (MCS)
The input is made in the currently valid measuring system (inch/metric)
An active diameter programming (DIAMON) is taken into account
Type: REAL
