8. USING THE SPECIAL FUNCTIONS
This chapter explains how to use special functions which are not used during normal cutting or plotting
operations.
8.1 Description of the Special Functions
The following describes the eight special functions.
(1) Enabling or Disabling the “;”, “,”, and “:” Commands (Only in GP-GL command mode)
While the COMMAND setting is GP-GL, this ;,: COMMAND function lets you switch the ENABLED/
DISABLED status for recognizing the input of the “;”, “,”, and “:” commands from the computer.
If your plotter fails to properly receive the first part of the data transmitted from the computer, the
problem may be attributable to these three commands. If this happens, change the ;,: COMMAND
setting to DISABLED.
(2) Controlling the Pen UP/DOWN Movement by the W COMMAND (Only in GP-GL command mode)
When the W command (for plotting a circle or arc) is output to the plotter while the COMMAND setting
is GP-GL, this W COMMAND function determines whether to move the pen to the specified starting
point for plotting either in raised status (when the W COMMAND setting is PEN UP) or in the pen’s
status (either raised or lowered) just prior to the plotter’s receipt of the W command (when the W
COMMAND setting is PEN DOWN).
Note that the PEN UP setting is only valid while the plotter is in CUTTER mode.
(3) Selecting the MODEL EMULATED Response (Only in HP-GL command mode)
While the COMMAND setting is HP-GL, this MODEL EMULATION function lets you specify how the
plotter responds when it receives the OI command from the computer.
When the MODEL EMULATED setting is 7550, the plotter sends back “7550B” in response to OI
command input. When 7595 is selected, the plotter sends back “7595A” in response to OI command
input.
(4) Selecting the CONDITION PRIORITY
The CONDITION PRIORITY function determines whether to place priority on the programmed cutting
conditions sent as commands from the computer or on the cutting conditions that have been manually
specified at the plotter’s control panel.
When the CONDITION PRIORITY setting is MANUAL, the plotter ignores any specification of cutting
conditions in the commands sent from the computer, so the cutting conditions can only be specified or
changed at the plotter’s control panel and the specified cutting conditions are retained even while the
plotter is turned off.
When PROGRAM is selected, the plotter will assume the latest cutting conditions that have been
specified either from its control panel or by command input. When the plotter is turned off, only the
cutting conditions that were specified at the control panel will be retained, while any cutting conditions
specified by command input will be lost.
(5) Enabling or Disabling SP and J Commands (SP,J COMMAND)
The SP,J COMMAND function lets you determine whether the plotter will acknowledge or recognize
the Pen Change command (the J command in GP-GL mode or the SP command in HP-GL com-
mand).
When the SP,J COMMAND setting is ENABLED, the current pen will be replaced by the pen corre-
sponding to the PEN No. specified by the Pen Change command.
When DISABLED is selected, all Pen Change command input is ignored.
