9-9 Section Software Limit

The relationship between the CW and CCW limit input signals, the software lim-
its, and the mechanical stoppers used in the system, is shown below.

The software limit function is enabled if an origin has been established (i.e., the
No Origin Flag is OFF) and the CW software limit setting is greater than the CCW
software limit setting. In any other situation, the software limit function will be dis-
abled and operation for the present position will proceed as follows.
•
From the stopped state, before pulse output is started, the present position is
set to 0.
•
During pulse output, the present position will be changed as long as the posi-
tion does not go outside the following upper and lower limits:
For pulse output in CW direction: 2,147,483,647 pulses (7FFFFFFF Hex)
For pulse output in CCW direction: --2,147,483,647 pulses (80000001 Hex)
9-9-2 Beginning Words of Operating Memory Area, Operating Data Area,
and Parameter Areas
The beginning words of the operating memory area, operating data area, and
common parameter area used for a Position Control Unit (PCU) are determined
(or set) according to the following.
•
Beginning word of the operating memory area, n = CIO 2000 + 10

•
Beginning word of the operating data area, l, is specified in m and m+1.
Set the beginning words of the operating data area and designate the axis
parameters used with the common parameters as shown below.
