9-2-3 Beginning Words of Operating Memory Area, Operating Data Area,
and Parameter Areas
When TEACH is executed, values will be written in the position data area in the
internal memory of the PCU. Since this data will be erased when the power is
turned OFF or when the PCU is restarted, perform data saving operation to pre-
serve the data. Refer to 5-6 Saving Data.
Address Position data
11F8 Hex Position #2 (rightmost)
11F9 Hex
Position #2 (leftmost)
When positioning to a position determined using the teaching function, set the
position designation setting in the positioning sequence to absolute positioning.
If it is set to relative positioning, positioning will be performed to a position other
than the one obtained with the teaching function.
1. Set the operating data area using the parameters.
2. Move the axis to the teaching position (e.g., using JOG).
3. Set the teaching address in the operating data area.
4. Stop the axis, and then turn the TEACH Bit from OFF to ON.
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 × unit num-
ber
• Beginning word of the common parameter area, m = D20000 + 100 × unit num-
ber
• 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.
