Voltage output
varies with the time
(time-dependent
ramp):
M203 V... TIME...
The iTNC outputs the voltage as a function of the time. Starting from the active
voltage, the iTNC increases or decreases the voltage linearly in the time
programmed behind TIME to the value programmed behind V.
Input: Voltage V: 0 to 9.999 [V]
TIME: 0 to 1.999 [sec]
Duration of effect: M203 V... TIME... is effective until a new voltage is output
with M200 to M204.
Voltage output
varies with the time
(time-dependent
pulse):
M204 V... TIME...
The iTNC outputs the value programmed after V... as a pulse. The duration of
the pulse is specified with "TIME...."
Input: Voltage V: 0 to 9.999 [V]
TIME: 0 to 1.999 [sec]
Duration of effect: M204 V... TIME... is effective until a new voltage is output
with M200 to M204.
8.14.2 Graphic simulation (without TOOL CALL)
Graphic simulation is also available on machines that operate without tool
definition (e.g., water jet and laser cutting machines):
In MP7315, specify the tool radius for the graphic simulation.
In MP7316, define the penetration depth of the simulated tool.
Use M functions to mark the program sections to be simulated and define
the functions in MP7317.x.
Furthermore, by entering in MP7312 as small a value as possible between 1
and 8, you should be able to detect an acceleration of the graphic simulation
(the 3-D graphics) in the Test Run operating mode. However, HEIDENHAIN
instead recommends entering the real values of the corresponding tooth
lengths in the LCUTS column of the tool table.
MP7312 Limitation of the tooth length LCUTS
Input: 0 = No limitation, infinitely long tooth length
> 0: Tooth length = 2 * tool radius * MP7312
MP7315 Tool radius for graphic simulation without
TOOL CALL
Input: 0.0000 to 99 999.9999 [mm]
MP7316 Penetration depth of the tool
Input: 0.0000 to 99 999.9999 [mm]
MP7317 M function for graphic simulation
MP7317.0 Beginning of graphic simulation
Input: 0 to 88
MP7317.1 Interruption of graphic simulation
Input: 0 to 88
