Axis Operating Input Memory Areas Section 4-8
4-8 Axis Operating Input Memory Areas
The Axis Operating Input Memory Areas are allocated inputs for monitoring
the status of axis operations of the Servo Drive and Servomotor axes that are
connected using MECHATROLINK communications. These include present
position and axis operating status.
4-8-1 Axis Operating Input Memory Area Overview
The Axis Operating Input Memory Areas are allocated 25 words for each axis
in the CPU Unit's memory area set in PCU's Common Parameters (Axis
Operating Input Memory Area designation and beginning word of Axis Oper-
ating Input Memory Area).
The designated beginning word corresponds to the beginning word of the
area for axis 1, and the other areas are allocated words in sequence up to the
highest axis number registered in the scan list. For details on area allocations,
refer to
6-2-2 Scan List and PCU Area Allocations .
The beginning words of the Axis Operating Input Memory Areas are deter-
mined by the axis number of each axis using the following equation.
