parameters are read either continuously or in block, depending upon the time
base.
Even if the scope is in Continuous Trigger Mode, the Table data is not re-
read; only the motion parameters are continuously read from the MC Unit.
While the scope is running, all the scope controls except the Trigger Button
will be disabled. To change the time base or vertical scale, the scope must be
stopped and restarted.
The MC Unit records the parameter values at the required sample rate in the
Table, and then passes the information to the scope. The trace displayed is
therefore accurate with respect to the selected time base. There is, however,
a delay between when the data is recorded by the MC Unit and when it is dis-
played on the scope due to the time taken to upload the data via the serial
link.
When using Motion Perfect, please consider the following items:
• Motion Perfect provides complete programming functions, such as edit,
delete, rename, create, select and copy functions. When available, these
should be used instead of the equivalent BASIC system commands in the
Terminal Window. Motion Perfect cannot detect changes made by these
BASIC system commands and a project check will be required to resolve
inconsistencies.
• Use Reset the Controller on the MC Unit Menu to perform a software
reset of both the MC Unit and the Servo Driver (as DRV_RESET com-
mand).
• You do not need to close an Editor Window to run a program. It saves
time not to. It is better to open an edit session for each program you want
to see before running any programs. If there are programs already run-
ning, then it will not be possible to open an edit session.
• Do not turn the power ON and OFF or remove the serial connection when
using Motion Perfect. If you do so, a communications error message will
appear, and Motion Perfect will go off-line.
• You can force Motion Perfect to compare the computer project with the
MC Unit programs at any time by selecting Check project from the File
Menu.
Motion Perfect can be run in an off-line mode if it is unable to find a MC Unit
and open a valid project. This may occur if it does not find any MC Units con-
nected to the computer or if the project consistency check fails and the check
is canceled.
In the offline mode, all project-related functions will be disabled. The user will
only have access to
• Terminal Window (VT100 emulation).
• System software load.
• Communications setup.
A Terminal Window can be opened and an attempt can be made to establish
communications with the MC Unit. If the MC Units line mode >> prompt is
returned when the Enter Key is pressed, then the MC Unit can be communi-
cated with using the BASIC system commands (see the BASIC on-line help
for further information). The commands given in 6-2-4 Program Commands
and Functions can be used to manipulate programs using a terminal.
If the MC Unit stops responding during a development session and the same
project is reconnected, then it is likely the consistency check will be passed.
