M800/M80/E80/C80 Series Alarm/Parameter Manual 1 Operation Errors (M)

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.

Remedy

The selection of the AXIS SELECTION key's +/- direction is incorrect. The error is canceled by feeding the axis in the correct direction.

M01 External interlock axis exists 0004

Details

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

Remedy

As the interlock function has activated, release it before resuming operation. Correct the sequence on the machine side. Check for any broken wires in the "interlock" signal line.

M01 Internal interlock axis exists 0005

Details

The internal interlock state has been entered. The absolute position detector axis has been removed. A command for the manual/automatic simultaneous valid axis was issued from the automatic mode. The manual speed command was issued while the "tool length measurement 1" signal is ON. A travel command has been issued to an inclined axis whose base axis is in control axis synchronization across part systems. Selected an axis other than the 1st axis when the manual speed command was issued. A travel command has been issued to an axis stopped by the collision detection function. Positioning or interpolation command was issued during the spindle-mode rotary axis control mode.

Remedy

The servo OFF function is valid, so release it first. An axis that can be removed has been issued, so perform the correct operations. The command is issued in the same direction as the direction where manual skip turned ON, so perform

the correct operations. During the manual/automatic simultaneous mode, the axis commanded in the automatic mode became the manual operation axis. Turn OFF the "manual/automatic valid" signal for the commanded axis.

Turn ON the power again, and perform absolute position initialization. Turn OFF the "tool length measurement 1" signal to start the program by the manual speed command. Cancel the control axis synchronization across part systems, then issue a travel command to the inclined

axis.

Select the 1st axis of each part system when issuing the manual speed command. Cancel the collision detection alarm. Check the program after cancelling the error by reset.

M01 H/W stroke end axis exists 0006

Details

The stroke end function has activated (the input signal is "OFF") and one of the axes is in the stroke end status.

Remedy

Move the machine manually. Check for any broken wires in the "stroke end" signal line. Check for any limit switch failure.

IB-1501279-H

Details

The stored stroke limit I, II, IIB or IB function has activated.

Remedy

Move the machine manually. Correct any setting error of the parameters for the stored stroke limit.

M01 Chuck/tailstock stroke end ax 0008

Details

The chuck/tail-stock barrier function turned ON, and an axis entered the stroke end state.

Remedy

Reset the alarm with reset, and move the machine in the reverse direction.

M01 Ref point return No. invalid 0009

Details

2nd reference position return was performed before 1st reference position return has been completed.

Remedy

Execute 1st reference position return.

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 measurement mode (TLM) signal was validated. The sensor signal turned ON when there was no axis movement after the tool measurement mode (TLM) signal was validated. The sensor signal turned ON at a position within 100 μm from the final entry start position.

Remedy
