Setting The Measuring System (G70, G71, G700, G710) - Siemens SINUMERIK 840D sl Function Manual

Parameterizable axis status
The behavior with regard to the axis status after the end of the part program and NC Reset
can be parameterized via the following machine data:
MD30450 $MA_IS_CONCURRENT_POS_AX[<axis>] = <value>
<value>
1) PP end: Part program end

Setting the measuring system (G70, G71, G700, G710)

If a specific measuring system (inch/metric) is not explicitly defined in a synchronized action
with G70, G71, G700, G710, the measuring system active in the part program at the time the
synchronized action is executed takes effect:
● G70/G71 active in the part program:
– All the programmed position values are interpreted in the programmed measuring
– All the read position data is interpreted in the parameterized basic system.
● G700/G710 active in the part program:
– All the programmed position values are interpreted in the programmed measuring
– All the read position data is interpreted in the parameterized basic system.
The following rules apply when defining the measuring system in the synchronized action:
● If a measuring system is programmed in the condition part, this also takes effect in the
action part if a measuring system has not been specifically programmed there.
● If there is only a measuring system programmed in the action part, the system which is
currently activated in the part program takes effect in the condition part.
● Different systems of units can be programmed in the condition and action parts.
● The measuring system programmed in the synchronized action has no effect on the part
program.
