29 hex 1 hex Following
Error Counter
Overflow 1
The value that is obtained
*7
by dividing
the absolute encoder position (in pulses)
by the electronic gear ratio exceeded
±2
31
(2,147,483,648) during the
initialization of position data.
Review the operation range of the
absolute encoder position and the
electronic gear ratio.

Error Counter
Overflow 2
The position error in pulses exceeded
±2
29
(536,870,912). Alternatively, the
position error in command units
exceeded ±2
30
(1,073,741,824).
• Check to see if the Motor operates
according to the position command.
• Check on the force monitor to see if the
output force is not saturated.
• Adjust the gain.
• Maximize the Force Limit setting being
used.
• Wire the external encoder as shown in
the wiring diagram.
30 hex 0 hex Safety Input
Error
At least one of the input photocouplers for
safety inputs 1 and 2 turned OFF.
Check the input wiring of safety inputs 1
and 2.
33 hex 0 hex Interface
Input
Duplicate
Allocation
Error 1
There is a duplicate setting in the input
signal (IN1, IN2, IN3, and IN4) function
allocations.
Allocate the functions to the connector
pins correctly.
1 hex Interface
Input
Duplicate
Allocation
Error 2
There is a duplicate setting in the input
signal (IN5, IN6, IN7, and IN8) function
allocations.
2hex
Interface Input
Function
Number Error 1
There is an undefined number
specification in the input signal (IN1, IN2,
IN3, and IN4) function allocations.
Alternatively, a logic setting error was
detected.
3hex
Interface Input
Function
Number Error 2
There is an undefined number
specification in the input signal (IN5, IN6,
IN7, and IN8) function allocations.
Alternatively, a logic setting error was
detected.
4hex

Function
Number Error 1
There is an undefined number
specification in the output signal
(OUTM1) function allocation.
5hex
Interface Input
Function
Number Error 2
There is an undefined number
specification in the output signal
(OUTM2) function allocation.
8 hex External
Latch Input
Allocation
Error
There is an error in the latch input
function allocation.
• The function was allocated to input
signals other than IN5, IN6, or IN7.
• The function was allocated to NC.
• The function was not allocated for all
control modes.
Error No.
