Software Limit
Section 9-9
The relationship between the CW and CCW limit input signals, the software
limits, 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 func-
tion will be disabled and operation for the present position will proceed as fol-
lows.
• From the stopped state, before pulse output is started, the present posi-
tion is set to 0.
• During pulse output, the present position will be changed as long as the
position 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)

Beginning Words of Memory Areas
The beginning words of the operating memory area, operating data area, and
common parameter area used for a Position Control Unit (PCU) are deter-
mined (or set) according to the following.
• Beginning word of the operating memory area, n = CIO 2000 + 10
