The Ball Spline ball has fallen out
The Z-axis LM-guide ball has fallen out.
[How to Check]
Check what the Ball Spline has collided with.
Check the up/down and left/right movement of the Ball Spline.
Check the Z-axis LM Guide.
[Measures]
Replace the Ball Spline assembly and calibrate it.
Replace the corresponding Z-axis LM-guide and calibrate it.
E0A01 (EMER) An alarm was detected on the Axis H#
[Cause]
Encoder power cable is incorrectly connected
Since the ANC nozzle setting was incorrectly performed, an alarm occurred due to Z-
axis load
The Z-motor is defective
Defective contact of the CN8 cable in the SEDES Slave Board and SEDES CN2 cable
in the SEDES Board (Applicable only to SM series machines excluding the DECAN
F2, SLM, SM471 and SM48X machines.)
Problem with part thickness and backup pin setting
Defective servo driver
Unstable main power supply
Defective SEDES board
(Rear Z1~6 and R1, 2 and 3 alarm lamps are blinking at the Motor I/O)
(Applicable only to SM series machines excluding the DECAN F2, SLM, SM471 and
SM48X machines.)
Defective flat cable assembly
Occurrence of alarm due to noise (The Z limit is changed)
The Head Z-axis belt fixing bracket bolt has fallen out
When checking the P/S#2 connected to the M/C#1, 24V is not outputted (18.6V)
[How to Check]
1. Check the up/down and left/right movement of the Z-axis.
2. Check the grease application status.
3. Check the Z offset data.
4. Check the assembling state of the power cable and encoder cable.

Troubleshooting
5. Check the operation state of the servo driver.
6. Check the assembling state of the SEDES board connector cable.
7. Check the assembling state of the flat cable.
8. Check the output of the 24V power supply.
9. Check for PCB warping, backup pin setting and part data.
(Check other related items.)
[Measures]
When checking the Mini Amp Alarm Code, reassemble the "16" Overload "21"(Enc
communication error) Encoder and power cable connector.
Perform the setting of the ANC nozzles again.
Replace and calibrate the Z-motor.
Reassemble the CN8 cable in the SEDES Slave Board and SEDES CN2 and 8 cable
connectors.
Set the part thickness, as well as the backup pin position and height.
Replace the servo driver.
Install the local power supply AVR.
Replace the SEDES board.
Replace the flat cable assembly.
Perform the Axis Home Calibration and set the limit.
Reassemble the Head Z-axis belt fixing bracket.
Replace the 24V power supply.
E0A02 An error (follow-up error) occurred to the $A axis
[Cause]
Defective contact of the F-SEDES-CN8 cable connected to the X7143N SEDES
board.
(Applicable only to SM series machines excluding the DECAN F2, SLM, SM471 and
SM48X.)
Defective X7043 SEDES board
(Applicable only to SM series machines excluding the DECAN F2, SLM, SM471 and
SM48X.)
Defective Z-axis motor
Defective Head I/F board contact
Defective Motor I/F board contact (DECAN F2, SM471 and SM481)
Defective SEDES Slave Board

(Applicable only to SM series machines excluding the DECAN F2, SLM, SM471 and
SM48X.)
[How to Check]
1. Check the assembling state of the DES board cable.
2. Check the operation state of the SEDES board.
3. Check the state of the Servo Driver Board and related cables.
4. Check the operation state of the corresponding axis motor.
(Check the I/O operation state as well as the resistance of the power supply section.)
5. Check the operation state of the SEDES Slave Board.
[Measures]
Reassemble the F-SEDES-CN8 cable connected to the X7143N SEDES board.
Replace the X7043 SEDES Board.
Replace the Z-axis motor and calibrate it.
Reassemble the Head I/F Board power supply cable and connector.
Replace the SEDES Slave Board.
E0A03 Axis $A homing error - AMP, AMP, index mark, auxiliary home sensor …
[Cause]
The serial cables (CN2, CN8) connecting SEDES slaves are defective.
(Applicable only to SM series machines excluding the DECAN F2, SLM, SM471 and
SM48X.)
The contact of the serial cables (CN2, CN8) connecting SEDES slaves is defective.
The 24V (PS2) power supply does not work since a short-circuit occurred to the right
board with one set of probe pins being stuck in the #51 slot of the feeder base.
Defective power supply (no output voltage).
The Z-axis motor does not operate or is defective.
The position of the Z phase of the Z-axis motor has been changed: The Z pulley has
turned.
Defective contact of the Axis Board connector.
Defective Head R-axis sensor.
The connector of the cable supplying power to the R Stepping Driver is not properly
connected.
[How to Check]
1. Check the state of the physical movement of the corresponding axis.
2. Check the assembling state of the SEDES Board cables.
