10200 INT_INCR_PER_MM N01 G2, K3
- Calculation resolution for linear positions DOUBLE PowerOn
LINK
- - 10000. 1.0 1.0e9 2/2 M
Description: This MD defines the number of internal increments per millimeter.
The accuracy of the input of linear positions is limited to the calculation accuracy
by rounding the product of the programmed value and the calculation accuracy to an
integer.
In order to keep the executed rounding easily understandable it is useful to use powers
of 10 for the calculation accuracy.
10210 INT_INCR_PER_DEG N01 G2, K3, R2
- Calculation resolution for angular positions DOUBLE PowerOn
LINK
- - 10000. 1.0 1.0e9 2/2 M
Description: This MD defines the number of internal increments per degree.
The accuracy of the input of angular positions is limited to the calculation accuracy
by rounding the product of the programmed value and the calculation accuracy to an
integer.
In order to keep the executed rounding easily understandable it is useful to use powers
of 10 for the calculation accuracy.
10240 SCALING_SYSTEM_IS_METRIC N01 G2, K3, A3, S1
- Basic system metric BOOLEAN PowerOn
SCAL
- - TRUE 0 - 2/2 M
Description: The MD defines the basic system used by the control for scaling length-dependent
physical variables for data input/output.
All corresponding data are stored internally in the basic units of 1 mm, 1 degree and
1 sec.
In the case of access from the interpreter ( part program and download ), from the
operator panel ( variable service ) or through external communication, scaling takes
place in the following units:
MD10240 $MN_SCALING_SYSTEM_IS_METRIC = 1: scaled in:
mm, mm/min, m/s2 , m/s3, mm/rev.
MD10240 $MN_SCALING_SYSTEM_IS_METRIC = 0: scaled in:
inch, inch/min, inch/s2, inch/s3, inch/rev.
The selection of the basic system also defines the interpretation of the programmed F
value for linear axes:
metric inch
G94 mm/min inch/min
G95 mm/rev. inch/rev.
If this machine data is changed, a startup is required because otherwise the
associated machine data that have physical units would be incorrectly scaled.
Proceed as follows:
● MD changed manually
First start up and then enter the associated machine data with physical units.
● MD changed via machine data file
First start up and then reload the machine data file so that the new physical units
are taken into account.
If the machine data are altered, alarm 4070 "Scaling machine data altered" is output.
