Alarms resulting from incorrect operation by the operator during NC operation
and alarms resulting from the machine fault are displayed.
The numbers given in the table can be referred to on the Alarm list screen
(Diagnosis group).

• When the spindle returned to the
reference point, the near-point
detecting limit switch was not
stopped by the dog but it overran the
dog instead.

• One of the axes did not pass the
Z-phase of the detector on the initial
return of the machine to the reference
point after the power was turned ON.

• When returning manually to the
reference point, the direction of the
return differs from the axis movement
direction which has been designated
by the AXIS SELECTION key.

• The external interlock function has
been activated (the input signal is
"OFF"), and one of the axes is
interlocked as a result.

• An internal interlock status is
established.

• Increase the length of the near-point
dog.

• Reduce the speed at which the
spindle returns to the reference
point.

(Note) This error may not occur

depending on the system.

• Move the machine by an amount
equivalent to one or more rotations
of the detector in the reverse
direction to that of the reference
point, and proceed with reference
point return again.

• An AXIS SELECTION key
corresponding to the wrong direction
has been selected. The error is
released by feeding the axis in the
correct direction.

• Since the interlock function has been
activated, it must first be released
before operation is resumed.

• Check the sequence on the machine
side.

• Check for breakage in the interlock
signal wire.

• Since the servo "OFF" function has
been activated, it must first be
released.

• An axis for which axis removal is
valid has been commanded. Carry
out the correct operation.

• The manual skip is designated in the
same direction as when this turned
ON. Carry out the correct operation.
