# 1 CRFx When the servo alarm SV0445 (soft disconnection), SV0447 (hard
disconnection (separate)), or SV0421 (dual position feedback
excessive error) is issued:
0: The reference position established state is not affected.
1: The reference position unestablished state is assumed. (Bit 4
(APZ) of parameter No. 1815 is set to 0.)
Alarm and message
Number Message Description
PS0090 REFERENCE RETURN INCOMPLETE 1. The reference position return cannot be performed
normally because the reference position return start point is
too close to the reference position or the speed is too slow.
Separate the start point far enough from the reference
position, or specify a sufficiently fast speed for reference
position return.
2. An attempt was made to set the zero position for the
absolute position detector by return to the reference
position 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.
DS0300 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 pulse coder for the first time.
The battery or cable is thought to be defective. Replace the
battery with the machine turned on.
DS0307 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.
DS0308 APC ALARM: BATTERY LOW 2 The battery voltage of the absolute position detector dropped to
a level at which a replacement was required in the past.
(including during power off)
Replace the battery with the machine turned on.
DS0309 APC ALARM: REF RETURN
IMPOSSIBLE
An attempt was made to set the zero point for the absolute
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.
