MM4005
Local Mode
2.4.1
General Concepts
To communicate with the MM4005 controller, a language is needed that
both user and controller can understand. When communicating remotely
we use a motion control language that is described in the Remote Mode
section. A program downloaded remotely is stored in non-volatile memory,
as is a program created locally.
Any program in memory can be read and edited both locally and remotely.
For this reason, to create a program in local mode we need a way to enter
alpha-numeric commands from the front panel. Since the number of keys
available on the front panel is limited, the MM4005 controller uses a special
convention to enter motion program commands. Taking advantage of the
context-sensitive menus, commands are assigned to function keys and
numerical values are entered on the numerical keypad.
Because only four function keys are available, only three commands can be
viewed at a time (the fourth key is reserved to advance or exit the menu).
To avoid scrolling through the entire list, commands are grouped by cate-
gories.
When entering or editing a command line, the controller will display it on
the first four lines.
A command line can have up to 110 characters. The display has only 30
characters per line, so long command lines will take up several lines. For
this reason, an asterisk (*) will identify the beginning of each logical com-
mand line.
NOTE
To save display space when wrapping around a command line, the con-
troller does not look for command boundaries (separators). The result is
that commands and numbers will be split without any restriction.
Once a command line has been entered and terminated, it will disappear
from the display to make room for a new one. To scroll through the pro-
gram and view different command lines, the controller must be in the
Program Editing mode. The Program Creation mode does not allow you to
view program lines other than the one being written or edited.

Creating a Program
To start creating a program, first enter the Program mode by pressing the
key (from the top-level
or
menu)
and then press the
key to enable the program creation mode.
Since the controller can store up to 100 different programs, the first screen
will ask which program number you want to create. You can consider this
number as the program name. When retrieving a program, you will call it by
its assigned number.
Enter a program number on the numeric keypad and press
. If a pro-
gram with this number (name) already exists, a warning screen will appear.
In this case, press
to overwrite it or
to return to the
Program mode and start over again.
Once a valid program number is accepted, the controller enters the
Program Creation mode. As mentioned earlier, the commands are grouped
in categories. To select a particular command, the user must navigate
through a number of screens (menus). An important controller characteris-
