10200 INT_INCR_PER_MM
- Calculation resolution for linear positions
LINK
- -
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
- Calculation resolution for angular positions
LINK
- -
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
- Basic system metric
SCAL
- -
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:
