System philosophy
The engineering unit that specifies the distances of travelling can be freely
defined for each axis separately. The conversion is performed through the
use of the unit conversion factor, which is defined by the UNITS axis
parameter. The origin point of the coordinate system can be determined
using the DEFPOS command. This command re-defines the current position
to zero or any other value.
A move is defined in either absolute or relative terms. An absolute move
takes the axis (A) to a specific predefined position with respect to the origin
point. A relative move takes the axis from the current position to a position
that is defined relative to this current position. The figure shows an example
of relative (command MOVE) and absolute (command MOVEABS) linear
moves.
2.2.1 PTP control
In point-to-point positioning, each axis is moved independently of the other
axis. The TJ2-MC64 supports the following operations:
• Relative move
• Absolute move
• Continuous move forward
• Continuous move reverse.
