the feed axis control selection signal (SYNC<Gn138> or
SYNCJ <Gn140>) needs to be set to 0 to establish the
origin.
DS0020
REFERENCE RETURN INCOMPLETE
An attempt was made to perform an automatic return to the
reference position on the perpendicular axis before the
completion of a return to the reference position on the
angular axis.
However, this attempt failed because a manual return to
the reference position during angular axis control or an
automatic return to the reference position after power-up
was not commanded. First, return to the reference position
on the angular axis, then return to the reference position on
the perpendicular axis.

APC ALARM: NEED REF RETURN
A setting to zero position for the absolute position detector
(association with reference position and the counter value
of the absolute position detector) is required. Perform the
return to the reference position.
This alarm may occur with other alarms simultaneously.
In this case, other alarms must be handled first.
DS0306
APC ALARM: BATTERY VOLTAGE 0
The battery voltage of the absolute position detector has
dropped to a level at which data can no longer be held. Or,
the power was supplied to the Pulsecoder for the first time.
If this problem recurs after the power is turned off and then
back on, the battery or cable may be defective. Replace
the battery with the machine turned on.

APC ALARM: BATTERY LOW 1
The battery voltage of the absolute position detector has
dropped to a level at which a replacement is required.
Replace the battery with the machine turned on.

dropped to a level at which a replacement was required in

APC ALARM: REF RETURN
An attempt was made to set the zero point for the absolute
IMPOSSIBLE
position detector by MDI operation when it was impossible
to set the zero point.
Rotate the motor manually at least one turn, and set the
zero position of the absolute position detector after turning
the CNC and servo amplifier off and then on again.
DS0405
ZERO RETURN END NOT ON REF
The axis specified in automatic zero return was not at the
correct zero point when positioning was completed.
Perform zero return from a point whose distance from the
zero return start position to the zero point is 2 or more
revolutions of the motor.
Other probable causes are:
- The positional deviation after triggering the deceleration
dog is less than 128.
- Insufficient voltage or malfunctioning Pulsecoder.

A.3 ALARM LIST (SERIAL SPINDLE)
When a serial spindle alarm occurs, the following number is displayed on the CNC.
NOTE
*1 Note that the meanings of the Spindle Amplifier indications differ depending on
which LED, the red or yellow LED, is on. When the red LED is on, the Spindle
Amplifier indicates a 2-digit alarm number. When the yellow LED is on, the
Spindle Amplifier indicates an error number that designates a sequence problem
(for example, when a rotation command is entered with the emergency stop
state not released).
See "Error Codes (Serial Spindle)."
