17.3.4. Error related to conveyor (E08)

E0800 An alarm related to the motor axis occurred

[Cause]

 Defective motor power cable and encoder cable

 Defective servo motor

 Defective motor pulley assembly(As the motor pulley set screw is loosened, the origin

point is changed)

 Overload occurred due to chips and foreign materials on/around the ball screw of the

width adjustment axis

 The home sensor and limit sensor are damaged

 The conveyor cable is cut off

 The system file related to the conveyer origin is damaged

 Defective connection between the base control board and NCIO board

 The voltage supplied from the power supply unit is defective

 The cables connected to the motor and board are defective or the base control board is

defective.

[How to Check]

 Check whether the motor power cable and encoder cable are properly connected. If the

cable has a problem, replace it and check whether the same problem occurs

 Check whether the servo motor operates properly

 Check whether the motor pulley is assembled properly

 Check whether foreign materials exist on/around the ball screw and LM guide

Fast & Flexible Chip Shooter DECAN F2 Service Manual

 Check the operation state of the home sensor and limit sensor. If they have a problem,

replace them and check whether the same problem occurs

 Replace the conveyor cable and check whether the same problem occurs

 Overwrite and recover the backup system file and perform calibration. Then check

whether the same problem occurs

 Check whether the cable between the base control board and NCIO board is properly

connected. If it has no problems, replace the base control board and then check

whether the same problem occurs

 Check the input and output (24V) of the power supply and replace the power supply

and then check whether the same problem occurs

 Check the cable connection status. If it has a problem, replace the cable. If not, replace

the base control board and check whether the same problem occurs.

[Measures]

 Replace the power cable of the corresponding motor and encoder cable.

 Replace the servo motor.

 Reassemble the motor pulley set screw and perform conveyor calibration.

 Clean the ball screw and LM guide. Then apply grease to them and perform conveyor

calibration.

 Replace the home sensor and limit sensor.

 Replace the conveyor cable.

 Recover the system file related to the conveyor origin position by overwriting the file

with the backup system file and perform conveyor calibration.

 Replace the base control board.

 Replace the power supply unit.

 Replace the motor cable or base control board.

E0801 The BUT Up/Down error occurred

[Cause]

 Since the height of the BUT Up detection sensor is not set correctly, the BUT Up

detection sensor fails to detect the up-movement of the BUT

 Defective BUT Up detection sensor

 Defective BUT Motor Driver

 Since foreign materials exist inside the PCB guide, the clamp backup pin position was

changed. Therefore, a BUT Up error occurred

 The position of the sensor dog detecting the BUT Up movement is not at the center of

the sensor but is off center. Therefore, it cannot detect the BUT Up movement

properly

17-29

Troubleshooting

[How to Check]

 Check whether the sensor dog of the BUT can detect the BUT Up detection sensor by

moving the BUT

 Perform a test to determine whether the BUT Up sensor works properly. If it is

defective, replace the sensor and check whether the same problem occurs

 Check the code displayed at the BUT Motor Driver for any problem.

 Check whether foreign materials exist inside the PCB guide

 Check whether the sensor dog is at the normal position

[Measures]

 Set the installation height of the BUT Up detection sensor again.

 Replace the BUT Up detection sensor.

 Replace the BUT Motor Driver.

 After removing the PCB guide, remove the foreign materials.

 Adjust the position so that the sensor dog will be located at the center of the sensor.

E0802 The stopper Up/Down error occurred

[Cause]

 Defective stopper cylinder

 Defective Stopper Cylinder Up detection sensor

 Defective solenoid valve of the stopper cylinder

[How to Check]

 Perform the stopper UP/Down test manually to check whether the cylinder operates

properly. If it has a problem, replace the cylinder and check whether it operates

properly

 Check whether the detection sensor detects the stopper when moving the stopper up. If

it has a problem, replace the sensor and check whether the sensor detects the up-

movement of the stopper

 Check whether the stopper cylinder solenoid valve operates properly when moving the

stopper up. If it has a problem, replace the solenoid valve and check whether the same

problem occurs

[Measures]

 Replace the stopper cylinder.

 Replace the Stopper Up detection sensor.

 Replace the solenoid valve.
