Appendix 7.1 Operation Errors (M)
M01 Hi-ac skip coord retrieval err 0029
Details
Failed to retrieve the skip coordinate value from the drive unit.
Remedy
- Check the wiring.
- Check the parameters.
M01 Now skip on 0030
Details
The "skip input" signal remains enabled when the operation has shifted from skip retract to
measurement.
Remedy
- Increase the skip retract amount.
M01 No skip 0031
Details
Even though the 1st skip was to the correct position, the 2nd skip could not be found.
Remedy
- Check whether the measurement target has moved.
M01 Movement prohibited during tool retract 0035
Details
An axis movement was attempted from the tool retract position.
The movement was attempted by a manual command in the tool return.
Remedy
It is not allowed to move an axis arbitrarily from the tool retract position. Take the following
steps to move the axis.
- Cancel the program execution by reset.
- Use the tool escape and retract function and let the axis escape from the tool retract
position.
The interruption by a manual command is not allowed in a tool return. Take the following
step to move the axis.
- Cancel the program execution by reset.
M01 Chopping axis R-pnt incomplete 0050
Details
Chopping mode has been entered while the chopping axis has not completed reference
position return.
All axes interlock has been applied.
Remedy
- Reset the NC or disable the "chopping" signal, and then carry out the reference position
return.
M01 Synchronous error excessive 0051
Details
The synchronization error of the primary and secondary axes exceeded the allowable value
under synchronous control. A deviation exceeding the synchronization error limit value was
found with the synchronization deviation detection.
Remedy
- Select the correction mode and move one of the axes in the direction in which the errors
are reduced.
- Increase "#2024 synerr(allowable value)" or set "0" to disable error check.
- When using simple C-axis synchronous control, set "0" for "synchronous control operation
method".
