Calculating variables automatically G940
Use G940 to convert metric values to inch values. When you create
a new program you can select between metric units and inches.
Internally the control always calculates with metric values. If you read
out variables in an "inch" program, the variables are always output as
metric values. Use G940 to convert the variables to inch values.
Parameters:
H: G940 On=1 Off=0
0: Unit conversion active
1: Values remain metric
In inch programs, a conversion is required for variables that refer to a
metric unit of measurement.
