Basic Program Examples
Section 11-2
Sample Ladder Program
11-2-6 Positioning (Absolute Movement or Relative Movement)
Overview
This sample program sends a positioning command to a Servo Drive con-
nected through MECHATROLINK communications.
Execute this sample program only after starting MECHATROLINK communi-
cations (establishing a connection), executing the Servo Lock function, and
verifying that the Servo Lock is engaged.
In addition, when executing ABSOLUTE MOVEMENT, establish the origin by
performing an origin search before sending the position command.
In this example, positioning is performed on the Servo Drive registered as axis
1 using the ABSOLUTE MOVEMENT Bit or RELATIVE MOVEMENT Bit in the
Axis Operating Output Memory Area.
The Axis Operating Output/Input Memory Areas are based on the settings of
the Common Parameter Area, as shown below. The application example in
11-3-1 Initial PCU Settings
shows a sample program that can be used to
make the following settings.
Beginning word of Axis Operating Output Memory Areas: CIO 0000
(Axis 1 Operating Output Memory Area: CIO 0000 to CIO 0024)
Beginning word of Axis Operating Input Memory Areas: CIO 1000
(Axis 1 Operating Input Memory Area: CIO 1000 to CIO 1024)
This sample program uses the following parts of the CPU Unit's I/O memory
in addition to the CIO Area words listed above.
