MM4005
Feature Descriptions Tutorial
Automatic Program Execution on Power-On: EO Command or from the Front Panel
When the power is turned on, after the initialization, the MM4005 controller
can start executing a specified stored program a pre-defined number of
times. This function can be setup on the front panel (
→
→
), or through the remote command EO
(automatic Execution on power On). The status of this mode can be read
with the EO? command.
Before executing the desired program, the controller executes MOTOR
and a HOME search on all installed axes.
Example
On start-up, MM4005 executes an absolute motion of 40 mm on axis num-
ber 1:
1XX
| Erase program #1.
1EP
| Edit program #1.
1PA40
| Move axis #1 to absolute position 40 mm.
QP
| Exit program edit mode.
1SM
| Save program in non-volatile memory.
1EO
| Execute program #1 one time on power-on.
Continuous Motion: MV Command
Some applications require that one or more axes be moved continuously.
This usually applies to rotary axes where the limit switches can be eliminated.
A continuous (infinite) motion is defined with the MV command and is gov-
erned by the following rules.
The MV command starts a motion on the selected axis. The velocity is set
by the usual xxVAnn command. The command format is:
xx
MV
+
For motion in positive direction.
xx
MV
-
For motion in negative direction.
Where:
xx
—
Axis number.
An infinite motion works in the background, without affecting the operation
of the other axis.
In a master-slave system, if the master axis starts an infinite motion, the
slave axis will also execute an infinite motion with the pre-defined velocity
ratio (GR).
The ST command stops an infinite motion.
To solve the overflow display problem inherent to an infinite motion, the
CD command allows the user to set a periodic cycle to the position
counter. Defining, for example, a cycle of 360° for a rotary stage will reset
the position counter every time it reaches 360° in the positive direction. In
the negative direction, instead of counting negative values when 0 position
is reached, the counter is set to 360°.
NOTE
Using of the MV command (Infinite movement) is possible only after set-
ting of a periodic cycle (CD command) and only for rotary stages.
