In regards to position registers, which coordinate element is represented by PR[1,3]?

In the context of position registers in FANUC robots, PR[1,3] specifically accesses the coordinate element associated with the Z-axis. In a position register, each coordinate axis typically corresponds to a different element within the register.

For instance, the elements are generally represented as follows:

• PR[n,1] represents the X coordinate,

• PR[n,2] represents the Y coordinate,

• PR[n,3] indicates the Z coordinate, and

• PR[n,4] might refer to additional elements such as orientation or other parameters linked to movement.

Given this structure, PR[1,3] effectively retrieves the value of the Z coordinate for the first position register. Understanding this organization is key for programming and ensuring that the robot operates correctly in a three-dimensional space, allowing for precise movement and task execution.
