Changing to CS1W/CJ1W-NC271/471/F71 from CS1W/CJ1W-NC113/133/213/233/413/433
Operating Memory Area
In the CS1W/CJ1W-NC271/471/F71 PCU, the Operating Memory Area allocations and functions have
changed, as shown in the following table.
A comparison of the functions of these words is provided in the following table. The differences between the
functions, such as in axis operations executed by the Operating Memory Area words, are explained later in this
appendix.
Operating Memory Area words for CS1W/CJ1W-NC113/133/213/233/413/433 PCUs are shown in the follow-
ing table as those for the X axis of the CS1W/CJ1W-NC113 PCU, and the beginning word n is calculated using
the following equation.
n = 2000 + (unit number × 10)
The Operating Memory Area words for CS1W/CJ1W-NC271/471/F71 PCUs are calculated for each axis using
the following equation.
a = Beginning word of Axis Operating Output Memory Areas specified in Common Parameters + (Axis
No. − 1) × 25
b = Beginning word of Axis Operating Input Areas specified in Common Parameters + (Axis No. − 1) × 25

Word Bits
a 00 Used as linear interpolation command
bits.
Memory operation functions are not
01
provided, so memory operation com-
02
mand bits are not allocated.
03 The function of this bit is the same.
04 The function of this bit is the same.
05 The method for starting interrupt feed-
ing has been changed.
This bit is an Interrupt Feeding Desig-
nation Bit for ABSOLUTE/RELATIVE
MOVEMENT, and is used together with
ABSOLUTE/RELATIVE MOVEMENT
bits.
06 The function of this bit is the same.
07 The function of this bit is the same.
08 The function of this bit is the same.
When the DECELERATION STOP Bit
is ON, however, PRESENT POSITION
PRESET cannot be received.
