11.1.1 Errors

Outline for the error codes and warning codes detected by the QD74MH are shown
below.
Error/warning code
1 to 999
1000 to 1899
1900 to 1999
2000 to 2099
2100 to 2199
11000 to 11999
Types of errors are shown below.
• System errors by hardware failure, etc.
• Operation errors at operation start or in operation
• Interface errors
• Servo errors detected by servo amplifier

error codes by the decimal in the buffer memory.
Axis cannot be started in error occurrence. Eliminate the error cause, and then start
the axis after resetting the error. If the axis is started in error occurrence, the error
code is unchanged.
(1) System errors (Error code: 1 to 999)
The system errors occur by hardware failure, etc. The system errors cannot be
reset. If the multiple system errors occur simultaneously, the smallest number is
given to priority.
(2) Operation errors (Error code: 1000 to 1899)
The operation errors occur at the following timing.
If the other errors occur at operation error occurrence, the error code is updated.
(a) At PLC READY ON
The parameters are checked at leading edge (OFF to ON) of PLC READY
signal ON [Y0] (at parameter change request). An "error code 1037" will
occur if there is a mistake in the parameter setting details.
At that time, the Unit READY signal [X0] does not turn ON. Correct the
parameters, and then turn ON the PLC READY signal [Y0] after resetting
the error.
