M01 Illegal op in mid pt sg block 0013
Details
The operation mode was changed to MDI during single block stop at the middle point of G28/
G29/G30.
Remedy
- Change the operation mode.
- Reset to clear the alarm.
M01 Sensor signal illegal ON 0019
Details
The sensor signal was already ON when the "tool length measurement 1" signal was validat-
ed.
The sensor signal turned ON when there was no axis movement after the "tool length mea-
surement 1" signal was validated.
The sensor signal turned ON at a position within 100 μm from the final entry start position.
Remedy
- Disable the "tool length measurement 1" signal and move the axis in a safe direction.
- Disabling the sensor signal also clears the operation alarm.
(Note) When the "tool length measurement 1" signal is disabled, the axis can be moved in ei-
ther direction. Pay attention to the movement direction.
M01 Ref point retract invalid 0020
Details
Reference position retract was performed while the coordinates had not been established.
Remedy
- Execute reference position return.
M01 Tool ofs invld after R-pnt 0021
Details
Reference position return had been performed during the tool retract and return, which inval-
idated the tool compensation amount after the reference position return.
Remedy
- The error is cleared if the operation mode is changed to other than reference position return
before the axis performs reference position return.
- The error is cleared when the tool return is completed.
- The error is cleared if reset 1 is input or the emergency stop button is pushed.
M01 R-pnt ret invld at abs pos alm 0024
Details
A reference position return signal was enabled during an absolute position detection alarm.
Remedy
- Reset the absolute position detection alarm, and then perform the reference position return.
M01 R-pnt ret invld at zero pt ini 0025
Details
A reference position return signal was input during zero point initialization of the absolute po-
sition detection system.
Remedy
- Complete the zero point initialization, and then perform reference position return.
M01 High-accuracy skip disabled 0028
Details
The drive unit's hardware or software does not conform to the high-accuracy skip.
Remedy
- The software or hardware does not conform to the function. Contact service center.
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 Rtn dir err in manual measure 0033
Details
Return direction in manual measurement is the opposite of the parameter setting.
Remedy
- Check and correct the "#2169 Man meas rtrn dir (Return direction in manual measurement)"
setting.
- Move the axis manually to a safe position in the direction set by "#2169 Man meas rtrn dir
(Return direction in manual measurement)", then reset.
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.
