Description
Cam No. specified by (S1) is outside the
range of 1 to 256.
Cam data which No. is specified by (S1)
does not exist in cam open area.
The end device number for cam position
calculation control data which the first
number of storage cam position calculation
control data is specified by (S2) is outside
the range.
The first number of the storage device for
cam position calculation control data
specified by (S2) is not even-numbered.
Cam position calculation type specified by
cam position calculation data has been set
other than 0 or 1.
Cam axis length per cycle is outside the
range of 1 to 2147483647.
Cam axis current value per cycle is outside
the range of 0 to (Cam axis length per
cycle).
The device No. which stores the result of
cam position calculation specified by (D) is
outside the range.
Odd-numbered device has been set in the
device No. which stores the result of cam
position calculation specified by (D).
Cam axis current value per cycle cannot be
calculated for those axes.
• Number of words (n) to be written is
outside the range of 1 to 256.
• The CPU shared memory address (D) of
self CPU of the writing destination device
is outside the range (800H to FFFH) of the
CPU shared memory address.
• The CPU shared memory address (D) of
self CPU of the writing destination device
+ number of words (n) to be written is
outside the range (800H to FFFH) of the
CPU shared memory address.
• Start device No. (S) which writing data are
stored + number of words (n) to be written
is outside the device range.
• MULTW instruction was executed again
before MULTW instruction is executed and
complete bit device is turned on.
• (D1) is a write-disabled device.
• (S) is a bit device and the device number
is not a multiple of 16.
• PX/PY is set in (S) to (S)+(n-1).

Error Processing
Correct the program so that the cam No. is
within the range of 1 to 256.
Correct the program to specify a cam No. in
which cam data exists.
Correct the program so that the end device
number for cam position calculation control
data is within the setting range.
Correct the program so that the device
number is an even-numbered.
Correct the program to set the cam position
calculation type to 0 or 1.
Set the value within the range of 1 to
2147483647.
Set the value within the range of 0 to cam
axis length per cycle.
Correct the program so that the device
number is within the range.
Correct the program so that the device
number is an even-numbered.

value.
• Correct the program so that the number of
words (n) to be written is within the range of
1 to 256.
• Correct the program so that the CPU
shared memory address (D) of self CPU of
the writing destination is within the range of
CPU shared memory address.
• Correct the program so that the CPU
shared memory address (D) of self CPU of
the writing destination + number of words
(n) to be written is within the range of CPU
shared memory address.
• Correct the program so that start device No.
(S) which writing data are stored + number
of words (n) to be written is within the
device range.
• Execute MULTW instruction again after the
complete bit device of MULTW instruction
is turned on.
• Correct the program to set a write-enabled
device at (D1).
• When (S) is a bit device, set the device
number to be multiple of 16.
• When (S) is a bit device, do not set PX/PY.
