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 (T
I) (TI < 0)
6735
Incompatible derivative gain (K
D)
(K
D < 0 or 201 ≤ KD)
6736 Incompatible derivative time (T
D) (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)".
