number displayed after error name(such as 0001). "M01" alarms are listed in ascending order in
this manual.
M01 Dog overrun 0001
Details
When returning to the reference position, the near-point detection limit switch did not stop
over the dog, but overran the dog.
Remedy
- Increase the length of the near-point dog.
- Reduce the reference position return speed.
M01 Some ax does not pass Z phase 0002
Details
One of the axes did not pass the Z-phase during the initial reference position return after the
power was turned ON.
Remedy
- Move the detector one rotation or more in the opposite direction of the reference position,
and repeat reference position return.
M01 R-pnt direction illegal 0003
Details
When manually returning to the reference position, the return direction differs from the axis
movement direction selected with the AXIS SELECTION key.

canceled by feeding the axis in the correct direction.
M01 External interlock axis exists 0004

The external interlock function has activated (the input signal is "OFF") and one of the axes
has entered the interlock state.
