If only P1 is set, P2 will move the same distance as P1 and then automatically be set to
that point. In setting by IP command, an error will result if P1 is set to a point that would
place P2 outside the plotting area. In setting by the operation panel, however, it is per­
missible to set P1 to a position that will place P2 outside the plotting area,
Pressing the P1 or P2 key on the panel will move the pen to the respective posi­
tion, thus enabling you to confirm the current setting. If P2 is set to a point outside the
plotting area, the pen will move toward it but stop at the boundary of the plotting area
(2) Setting by IP command
it is possible to set P1 and P2 by IP command. For example, if
” IP0,0,4000,2500;"
is sent, PI will be set to (0,0) and P2 will be set to (4000,2500). At this time, the
parameter's coordinate value must be a plotter coordinate. When rescaling, the active
coordinate system is the user coordinate system but the parameter values will be the
plotter coordinates.

In both the IP command and control panel setting, specifying only P1 will cause P2 to
move the same distance as P1 and will then automatically set it to that point. For exam­
ple, after executing the above statement to set P1 and P2, if
"IP1000,1000;"
is sent, P1 will be set at (1000,1000) and P2 will be set at (5000,3500).

® Scaling by SC command
The SC command determines the user coordinate values for P1 and P2 respectively after
they have been set to the desired positions. For example, if
"IP1000,2000,4000,2500;"
"SC0,1,0,1;"
