<1> 00= "Travel shortest distance" with round
axis with G90
<2> [LU]=the length unit set by the actual value
evaluation factor (e.g. P169/P170 [330.4] with
motor encoder in slot C) e.g. 0.001 mm
<3> - High Byte = first G function:
90=Absolute dimension (with round axis
modulo MD11)
91=incremental dimension (relative, with
round axis no modulo function)
- Low Byte= second G function=
acceleration override:
30=100%, 31=10% ... 39=90%
Number representation: parameter decimal
coded hexadec. in connector, example:
absolute positioning with 100% acceleration
==> Parameter = 9030 (dec.;= factory setting)
==> Connector = 5A1E (hex)
