HOME SEARCH is discussed separately because it is an important proce-
dure that deserves special attention. In this mode, the controller is execut-
ing a home search algorithm on one or more axes. A home search cycle
should not be interrupted. The controller will exit this mode automatically
upon task completion.
The controller displays a set of hierarchical menus to navigate the various
controller modes. It can be viewed as a "glue logic" between all the other
modes.
REMOTE Mode
To operate in REMOTE mode, the controller must be connected through
one of its interfaces (RS-232-C, RS-485 or IEEE-488) to a computer or termi-
nal. In this mode. all commands are received remotely and the controller
executes them as directed. The MM4006 command language consists of 185
commands which are described in chapter 3.
The functions available in REMOTE mode are similar to the ones in LOCAL
mode. The main difference is that the MOTOR OFF / MOTOR ON c a s e s
are handled by the command interpreter so there is no need to distinguish
between them. The controller will refuse to execute motion commands
when the motors are turned off and will set the appropriate error flag.
Another difference between LOCAL and REMOTE is that the SETUP m o d e
is not available remotely. Some SETUP parameters can be changed but the
controller cannot be placed remotely into a setup mode.
PROGRAMING mode is enabled and disabled b y specific commands. All
valid commands sent in this mode are not executed immediately but stored
as part of a motion program.
MOTION is a general mode of operation in which an axis is commanded to
move. The most complex motions result from program execution. Other
types of motion include manual JOG and a point-to-point MOVE.
HOME Search mode has the same meaning and functionality as in LOCAL
mode. A home search cycle should not be interrupted. The controller will
exit this mode automatically on task completion.
Immediate Mode
This is not an operating mode in which the controller can be placed.
Rather, the term merely differentiates the way the controller responds to
remote commands. If a command is not being sent as part of a program. it
is executed "immediately" in immediate mode.
Remote Commands In LOCAL Mode
The controller may be operated in LOCAL mode when connected t o a
remote computer. The LOCAL mode has many screen and menu combina-
