38.4 Error Code List and Action
Operation error [M8067(D8067)]
0000 No error
6701
Continues
operation
• No jump destination (pointer) for CJ or CALL
instruction
• Label is undefined or out of P0 to P4095 due to
indexing
• Label P63 is executed in CALL instruction; cannot be
used in CALL instruction as P63 is for jumping to
END instruction.
This error occurs in the execution of operation. Review
the program, or check the contents of the operands used
in the applied instructions.
Even if the syntax or circuit design is correct, an
operation error may still occur.
For example:
"T500Z" itself is not an error. But if Z had a value of 100,
the timer T600 would be attempted to be accessed. This
would cause an operation error since there is no T600
device available.
6702 CALL instruction nesting level is 6 or more
6703 Interrupt nesting level is 3 or more
6704
FOR-NEXT instruction nesting level is 6 or
more.
6705 Operand of applied instruction is inapplicable device.
6706
Device number range or data value for operand of
applied instruction exceeds limit.
6707
File register is accessed without parameter setting of file
register.
6708 FROM/TO instruction error
This error occurs in the execution of operation.
• Review the program, or check the contents of the
operands used in the applied instructions.
• Verify that the specified buffer memories exist in the
equipment.
• Verify that the extension cables are correctly
connected.
6709 Other (e.g. improper branching)
This error occurs in the execution of operation. Review
the program, or check the contents of the operands used
in the applied instructions.
Even if the syntax or circuit design is correct, an
operation error may still occur.
For example:
"T500Z" itself is not an error. But if Z had a value of 100,
the timer T600 would be attempted to be accessed. This
would cause an operation error since there is no T600
device available.
6710 Mismatch among parameters
This error occurs when the same device is used within
the source and destination in a shift instruction, etc.
6730 Incorrect sampling time (T
S) (TS ≤ 0)
<PID instruction is stopped.>
This error occurs in the parameter setting value or
operation data executing PID instruction.
Check the contents of the parameters.
6732
Incompatible input filter constant (α)
(α < 0 or 100 ≤ α)
6733 Incompatible proportional gain (K
P) (KP < 0)
6734 Incompatible integral time (TI) (TI < 0)
6735
Incompatible derivative gain (K
D)
(K
D < 0 or 201 ≤ KD)
6736 Incompatible derivative time (TD) (TD < 0)
6740 Sampling time (T
S) ≤ Scan time
<Auto tuning is continued.>
The operation is continued in the condition "sampling
time (T
S) = cyclic time (scan time)".
6742
Variation of measured value exceeds limit.
(UPV < −32768 or +32767 < UPV)
<PID operation is continued.>
The operation is continued with each parameter set to the
maximum and minimum value.
6743
Deviation exceeds limit.
(EV < −32768 or +32767 < EV)
6744
Integral result exceeds limit.
(Outside range from −32768 to +32767)
6745
Derivative value exceeds limit due to derivative gain
(K
D).
6746
Derivative result exceeds limit.
(Outside range from −32768 to +32767)
6747
PID operation result exceeds limit.
(Outside range from −32768 to +32767)
