Some ax does not pass Z phase

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 ref-
erence position return.
M01

R-pnt direction illegal

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

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

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
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.
