Memory Operation Procedure Section 8-2
8-2 Memory Operation Procedure
The procedures for setting data for memory operation are explained below
using the X axis as an example.
1,2,3... 1. Set the common parameters. (Refer to 4-3 Common Parameter Area .)
m: Set the operating data area either to DM or to EM.
m+1: Set the beginning word of the operating data area (I).
m+2: Designate the axis parameters.
2. Power up again or restart.
The data in the common parameter area set in (1) above is enabled.
3. Transfer the data. (Refer to SECTION 5 Transferring and Saving Data .)
Transfer the data set for the common parameters and for the axes to the
PCU.
4. Execute START.
Set the sequence number for beginning operation (word n+16, bits 00 to
15).
Turn ON the Sequence Number Enable Bit (word n, bit 00).
Turn START (word n, bit 01) or INDEPENDENT START (word n, bit 02)
from OFF to ON.
The operations in (1) and (2) above are required when using a PCU for the
first time, or when modifying the data in the common parameter area.
The procedure given in step 4 is also used to start sequence number 0.
8-3 Setting Data for Memory Operation
A simple explanation of the axis parameter area and operating memory area
settings that are used when executing memory operation is given below.
For setting methods and other details, refer to 4-4 Axis Parameter Area and 4-
5 Operating Memory Area .
8-3-1 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
×
unit
number
• Beginning word of the common parameter area, m = 100
×
unit
number
• 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.
Word Name Bit Reference
m Operating data area designation 00 to 15 SECTION 4
m+1 Beginning word of operating data area 00 to 15
m+2 Axis parameter designation 00 to 15
