Chapter 10 Troubleshooting

Symptom	Measures

Only cooling fan motor stops.	• Check to see if the cooling fans on the left of the main PCB and inward
	of the power supply PCB are rotating.
	If either of them is at standstill, check to see if connection from the
	cooling fan which is at standstill to P20 or P25 of the power supply
	PCB in the control box is proper. If they are connected properly, replace
	the cooling fan which is at standstill.

•Both cooling fans are rotating.

Check to see if connection from connector P16 of the main PCB to connector P10 of the power supply PCB in the control box is proper. Replace the main PCB with a new one.

•Check to see if the cooling fan on the right side of the main PCB is rotating.

If it is at standstill, check to see if connection from the cooling fan to P12 of the main PCB is proper. If they are connected properly, replace the faulty cooling fan.

•The cooling fan is rotating.

Replace the main PCB with a new one.

Power voltage upper or lower limit	• Is the voltage set on the panel?
error occurs.	If not, set it according to the power supply voltage of the area where
	the machine is used.
	• Is the tap voltage of the power transformer (terminal connection of mark tube
	T) adjusted to the power voltage of the area where the machine is used?
	If not, switch the tap connection.
	• Check the input voltage values in the power/voltage check test mode.
	Measure the power supply voltage with the tester and compare them.
	If the voltage value is significantly out of the normal range (±5v or
	more), calibrate it with the voltage calibration in the test mode.
	• When you cannot enter the test mode because this error frequently
	occurs, set the voltage to a relatively high value with the machine
	controller if it is E-D2 and to a relatively low value if it is E-D3 to avoid
	errors. Check and calibrate the voltage in the test mode.
	• Check to see if connection from connector P16 of the main PCB to
	connector P10 of the power supply PCB in the control box is proper.
	• Is the power supply abnormally low because a machine with a large
	capacity (compressor and the like) is used?
	Change the power to the other system. Use a stabilizer.
	• Replace the power PCB with a new one. Replace the main PCB with
	a new one.

X-axis motor overcurrent stop oc-	• Measure the resistance values of pin 1 and pin 2, pin 2 and pin 3, pin 3
curs.	and pin 4, pin 4 and pin 5, and pin 5 and pin1 at each connector section
	of two X-axis motors with the tester and check to see if they are
	approximately 2.1Ω.
	Replace the faulty motor with a new one.
	• Refer to the block diagram showing the cable connection and check to
	see if connection from the X-axis motor to the main PCB is proper.
	• Replace the main PCB with a new one.
