Axis Error Codes Section 12-5
12-5 Axis Error Codes
When a system error occurs, the Error Flag turns ON in the PLC Interface
Area and an error code is output. With the MC221, bit 14 of word n+10 turns
ON, and a 4-digit error code is output in hexadecimal to word n+11. With the
MC421, bit 14 of word n+18 turns ON, and a 4-digit error code is output in
hexadecimal to word n+19. The meanings of the error codes are explained in
the error code tables provided on the following pages.
Explanation of Tables Under the Code heading, the 4-digit hexadecimal code that is output by the
MC Unit is given first. The number given below it in parentheses is the way it
appears when decimal display is selected at the Programming Console.
Under the
Error name heading, the actual error name is given first and the
name as it appears at the Teaching Box is given below it in parentheses.
For details on the three stop methods, refer to 12-3 System Error Codes .
0033
(0051) Traverse continuation error
(WIND CONT ERR) An attempt was made to continue a traverse operation, but
the operation was unable to be continued for one of the fol-
lowing reasons:
• An error occurred at the axis during the traverse operation.
• The axis was decelerated to a stop during traverse opera-
tions, or jogging was executed while axis operation was
stopped, or the axis was moved by some other such oper-
ation.
In this case it will not be possible to continue, so restart the
program execution from the first block. The traverse operation
can be continued only under the following conditions:
• The traverse operation must have been stopped by a
deceleration stop and there must have been no errors gen-
erated while operation was stopped; or the axis must not
be able to be moved.

(0052) D code timeout
(D CODE TIME OVR) The CPU Unit was notified of the D code, but there was no
response from the CPU Unit.
The CPU Unit ladder program may be stopped, or another
ladder program with a higher priority may be running. Check
the CPU Unit and the ladder program.

003C
(0060) Driver alarm encountered
(DRV ALARM INPUT) The driver alarm input was turned ON or an attempt was
made to operate the axis or execute a Present position
CHANGE (G54) command or ORIGIN UNDEFINED (G29)
command with the driver alarm input ON after resetting an
error.
Check the status of the Servo Driver and correct the error if
one is found. Turn the Servo Driver ON if it’s OFF.
Emergency stop
003D
(0061) Error counter overflow
(ERR CNT OVERFLOW) The number of pulses in the error counter exceeded the
upper limit.
The upper limit will differ depending on the ON/OFF status of
the Error Counter Selection Bit.
OFF: The upper limit will be the error counter warning value
set in the system parameters.
ON: The upper limit will be 65,535 pulses.
This error could be caused by a disconnected/broken
encoder cable, electrical noise, improperly adjusted servo
system, or improperly adjusted/faulty mechanical system.
