5 OPERATION CONTROL PROGRAMS
POINT
The BMOV instruction cannot be used for the cam data write/read under the SV22
advanced synchronous control.
Use the CAMWR/CAMWR2 instruction (Cam data write) or the CAMRD instruction
(Cam data read). (Refer to Section 5.18.)

(Note-1) : "Nn" indicates the cam No.
(Note-2) : The device No. cannot be specified indirectly.
(Note-3) : Specify a multiple of 16 as the device number of bit data.
(Note-4) : PX/PY cannot be set.
(5) The cam No. that may be set as "Nn" is within the following range.
Q173D(S)CPU/Q172D(S)CPU
1 to 64
101 to 164
201 to 264
301 to 364
[Errors]
(1) An operation error will occur if:
• The cam data of cam No. specified with (D) or (S) are not yet registered to the
Motion controller
• The resolution of cam No. specified with (D) or (S) differs from the number of
transferred words specified with (n)
• (S) to (S)+(n-1) is outside the device range
• (D) to (D)+(n-1) is outside the device range
• (n) is 0 or a negative number
• PX/PY is set in (S) to (S)+(n-1)
• PX/PY is set in (D) to (D)+(n-1)
(2) When conversion of Motion SFC program is made in MT Developer2, an error will
occur if:
• (S) to (S)+(n-1) is outside the device range
• (D) to (D)+(n-1) is outside the device range
• (n) is 0 or a negative number
• PX/PY is set in (S) to (S) + (n-1)
• PX/PY is set in (D) to (D) + (n-1)
• (S) is a bit device and the device number is not a multiple of 16
• (D) is a bit device and the device number is not a multiple of 16
when (n) specified is a
word device
when (n) specified is a
constant
