device number to be multiple of 16.
• Change (D) or (n) so that the block transfer range is
within the device range.
• When (D) is a bit device, correct the program so that the
device number to be multiple of 16.
• Correct the program so that (n) is within the range of 0
to 1000000000.
• Correct the program so that the combination of (S) and
(D) is correct.
3904H TIME execution error The data of (S) is outside the range of 0 to 2147483647. Correct the program so that the data of (S) is within the
range of 0 to 2147483647.
3905H FMOV execution error • (D) to (D)+(n-1) is outside the range of the device.
• (n) is outside the range of 0 to 1000000000.
• (D) is the CPU buffer memory other than self CPU or
the module access device of the module other than self
CPU management.
• Change (D) or (n) so that the block transfer range is
within the device range.
• Correct the program so that (n) is within the range of 0
to 1000000000.
• Correct the program so that (D) is the CPU buffer
memory of self CPU or the module access device of the
module of self CPU management.
3908H CHGV execution error The specified axis number of (S1) is outside the range. Correct the specified axis number of (S1) to be within the
range.
390AH CHGP execution error • The specified axis number of (S1) is outside the range.

device.
• Correct the program so that (S3) to ((S3)+7) is within
the range of device.
390BH CHGT execution error The specified axis number of (S1) is outside the range. Correct the specified axis number of (S1) to be within the
range.
390CH CHGVS execution error The specified axis number of (S1) is outside the range. Correct the specified axis number of (S1) to be within the
range.
390DH MCNST executing error Error occurred during machine program operation start
request.
• Check the setting of machine program operation.
• Check the error content in detailed code and process
accordingly. (For the detail code, refer to MELSEC
iQ-R Motion Controller Programming Manual (Program
Design).)
3910H Assign (=) execution error • The (S) data is outside the range of the data type of (D).
• The device number which indirectly specifies (D) is
illegal.
• Correct the program so that the data of (S) is within the
range of the data (D) type.
• Correct the program so that to the device number which
indirectly specifies (D) is proper.
