NOTE
1 Specify G51 in a separate block.
2 After the figure is enlarged or reduced, specify G50 to
cancel the scaling mode.
3 No decimal point must be used to specify rates of
scaling magnification. Otherwise, an alarm (PS0006)
is issued.
4 Even in the case of decimal point input in fixed-point
format (when bit 0 (DPI) of parameter No. 2400 is set
to 0), the specification of no decimal point is assumed
for I, J, and K.
Explanation
- Axes for which scaling is enabled
For each axis for which scaling is to be enabled, set bit 1 (SCL) of
parameter No. 0012 to 1.
- Least input increment for specifying rates of magnification
The least input increment for specifying rates of magnification is 0.001
or 0.00001. When bit 1 (SCR) of parameter No. 6400 is set to 0, 0.0001
is used; when the bit is set to 1, 0.001 is used.
- Center of scaling
If X,Y,Z are omitted, the tool position where the G51 command was
specified serves as the scaling center.
CAUTION
If a setting value is employed as a scale factor without
specifying P, the setting value at G51 command time
is employed as the scale factor, and a change of this
value by another command, if any, is not effective.
- Scaling along all axes at the same rate of magnification
Set bit 4 (XSC) of parameter No. 7611 to 0. If scaling magnification
rate P is not specified, the magnification specified in parameter No.
6410 is assumed
- Scaling along each axis at a different rate of magnification
Set bit 4 (XSC) of parameter No. 7611 to 1. If scaling magnification
rates I, J, and K are not specified, the magnification set in parameter No.
6421 is used. Set a non-zero value in parameter No. 6421.
