Appendix E
Operating Data Area
The operating data designated in the data memory of earlier PCUs is allocated in the CS1W/CJ1W-
NC271/471/F71 in either the Common Operating Memory Area or Axis Operating Memory Area, as shown in
the following table.
A comparison of the functions for these words is provided in the following table. The differences between these
functions, such as in axis operations executed by the Operating Memory Area bits, are explained later in this
appendix.
Operating Data Area words for CS1W/CJ1W-NC113/133/213/233/413/433 PCUs are shown in the following
table for the X axis of the CS1W/CJ1W-NC113 PCU. The beginning word “I” is allocated in either the Special
I/O Unit Area or a user-specified DM/EM Area using settings in the Common Parameters.
The Operating Memory Area words for CS1W/CJ1W-NC271/471/F71 PCUs are allocated either to the Com-
mon Operating Memory Area or Axis Operating Memory Area, which are calculated using the following equa-
tions.
n = CIO 1500 + (unit number

code Error code b+4 --- The function of this word is the same
for errors that occur in individual axes.
The error codes for Unit common
errors are allocated as Unit error codes
in the Common Operating Memory
Area.

for data
transfer Number of write words n+6 The function is the same as data for WRITE DATA
used to transfer PCU parameters.
The data transferring method for the WRITE SERVO
PARAMETER function is different.
l+1 Write source area n+7
l+2 Write source word n+8
l+3 Write destination address n+9
l+4 Number of read words n+10 The function is the same as data for READ DATA
used to transfer PCU parameters.
The data transferring method for the READ SERVO
PARAMETER function is different.
l+5 Read source address n+11
l+6 Read destination area n+12
l+7 Read destination word n+13

operation Position (rightmost word) a+2 The function of these words is the same.
The data unit, however, is the command unit deter-
mined according to the setting for the electronic gear.
l+9 Position (leftmost word) a+3
l+10 Speed (rightmost word) a+4 The function of these words is the same.
The data unit, however, is the command unit/s deter-
mined according to the setting for the electronic gear.
l+11 Speed (leftmost word) a+5
l+12 Acceleration time (right-
most word) --- The acceleration and deceleration times cannot be
set in the PLC's memory area as operating data.
The acceleration/deceleration constants are set by
transferring them as Servo Parameters using the
Servo Parameter transferring functions.
