11.1.2 Warnings

11.1.3 Confirming the error and warning definitions

11.1.4 Resetting errors

Types of warnings are shown below.
• Servo warnings detected by servo amplifier
• Operation warnings at operation start or in operation
Warning code ( ) is represented in decimal. Confirm the warning codes by the
Md.8
decimal in the buffer memory.
(1) Servo warnings (Warning code: 2100 to 2199)
The servo warnings occur in the state immediately before error occurrence such
as the excessive regeneration or overload.
Error or normality operation cannot be executed by waning when warning is left
as it is though servo off is not executed.
The warnings can be automatically released by eliminating the warning cause in
the servo amplifier side. However, at that time, the detected servo warnings
cannot be automatically released in the QD74MH side.
Eliminate the error cause, and then execute the error reset after confirming the
warning release of the servo amplifier side.
If the other warnings occur at servo warning occurrence, the warning code is
updated.
(2) Operation warnings (Warning code: 11000 to 11999)
The operation warnings occur when the operation is limited by the wrong
positioning setting value at operation start or in operation. The positioning can be
executed or continued. However, the intended operation may not execute by the
warnings.
Execute the error reset after eliminating the error cause.
If the other warnings occur at operation warning occurrence, the warning code is
updated.
The error detection signal [X1] turns ON" at error occurrence. Simultaneously, the bit
corresponding to axis No. of axis that caused the error of the buffer memory "

The warning detection signal [X2] turns ON" at warning occurrence. Simultaneously,
the bit corresponding to axis No. of axis that caused the warning of the buffer memory
" Axis warning status" turns ON.
