Troubleshooting
17.3.8. Noise/ Vibration (E0C)
E0C00 Noise, vibration and shaking of the Z-axis/R-axis
[Cause]
Problem with the Z-axis belt tension
Working environment has been changed according to the workplace conditions
Defective cable pin work (defective green pin work of the R-axis motor power cable)
Defective R-Stepping Driver
Defective contact of the connector connecting the flat cable between the motor driver
and head
A crack occurred in the Right Head Board Bracket
Defective Z-axis offset and insufficient grease
[How to Check]
1. Adjust the Z belt tension.
2. Check the grease injection state.
3. Check the assembling state of the Z and R motor power cables and encoder cable
( Driver).
4. Check the Z offset setup and up/down and left/right movement.
[Measures]
Readjust the Z-axis belt tension using a head tension gauge.
Measurement value before adjustment: 110Hz ~ 130Hz

Fast & Flexible Chip Shooter DECAN F2 Service Manual
Measurement value after adjustment: 165Hz ~ 185Hz
Check the parameter.
Modify the parameter as follows:
#12: 812
#14: 7550
#1D: 550650
#1E: 21
Check the upper part of the Y-axis frame.
(Connect one set of the green connector pin of the motor power cable connector)
Replace the R-Stepping Driver.
Reassemble the connector connecting the flat cable between the motor drive and head.
Replace the Right Head Board Bracket.
Set the Z-axis offset again and apply grease.
E0C01 Noise occurred to the X-axis [Warm up the specific area in which vibration occurs and
press Ready button]
[Cause]
Working environment has been changed according to the workplace conditions
Grease is hardened at the X-axis ball screw hole.
The grease on the X-axis ball screw has turned black.
A machine with 3 phase and 220V was delivered. However, since it was operated with
3 phase and 380V after electrical work, a problem occurred to the driver.
With the X-axis Inner Guide-Mat being folded, friction between the Inner Guide-Mat
and the flat cable caused a noise.
Defective X-axis motor
[How to Check]
1. Check the grease application status (existence of grease and discoloration).
2. Check the status of the movement in the X direction in the Ready Off state (check
for any problems with the movement).
3. Using the jog box, check the status of the movement in the X direction in the Ready
On state. (Check for any problems with the movement)
4. Modify the Servo Driver Parameter (refer to the range of modification separately).
5. After replacing the Servo Driver, Coupling, Motor and Ball Screw in order, test
them.
[Measures]
Modify the Servo Driver Parameter setup values as follows:

#29: 2 1 ,
#2A: 30 40 50
Remove the grease at the X-axis ball screw hole completely and apply grease again.
Replace the X-axis ball screw.
Replace the X-axis Servo Driver.
Readjust and reassemble the Inner Guide-Mat position.
Replace the X-axis motor.
E0C02 Noise and vibration occurred to the Y-axis
[Cause]
Stiff ball screw movement, defective ball screw.
Y-axis ball screw is not secured.
(Bearing fell out due to the Snap Ring falling out.)
Working environment has been changed according to the workplace conditions.
Defective Y-axis Servo Driver
Defective ball screw assembly parallelism, defect of ball screw itself and bearing wear
of the Y-axis support unit.
Defective Y-axis support unit.
A problem occurred to the ball screw assembly parallelism.
[How to Check]
1. Check the grease application status.
2. Check the status of the movement in the Y direction in the Ready Off state. (Check
for any problems with the movement)
4. Using the jog box, check the status of the movement in the Y direction in the Ready
On state (Check for any problems with the movement)
5. Check the Servo Driver operation status (applied when it is necessary to modify the
parameter).
6. Check the operation state of the Servo Driver, Coupling, Motor and Ball Screw in
order.
[Measures]
Replace the Y-axis ball screw.
Reassemble the bearing and snap ring.
Modify the Servo Driver parameter. (2A: 30 60)
Replace the Y-axis Servo Driver.
