PART 9 TROUBLESHOOTING DATA

9.1 Probable Failures

Mechanical Failure

Reason Solution

The pressure adjustment is insufficient

Turn the hydraulic speed adjustment valve to the left and open the valve.

Blade teeth are broken Change the blade

The blade edge is welded in a

faulty manner Change the blade

The head vibrates during cutting

The flywheel and the rollers are

loose Tighten the nuts and bolts

The pressure adjustment is insufficient

Turn the hydraulic speed adjustment valve to the left and open the valve The blade edge is not sharp Change the blade

The cutting Duration is Long

The blade rotation speed is faulty Check the tooth direction The correct blade edge is not

used

Check the tags on the flywheel cover The blade edge is connected in a

faulty manner Check the tooth direction

The saw edge does not cut

Main motor rotates in the reverse

direction Check the phase sequence

The cutting pressure is excessive Adjust from the hydraulic speed adjustment valve

The blade rotation speed is low Use the schema on the flywheel cover The blade edge is not sharp Change the blade

The blade is not tensioned Tighten the blade

The clamp claws are unadjusted Adjust the clamp in a suitable manner. The flywheel is abraded Contact with the dealer

The cutting is not regular

The blade bearings can not hold the blade.

Adjust the blade rectification arm so as to be closer to each other

The blade is rotating very rapidly. Use the schema on the flywheel cover The blade bearings are adjusted

to be far

Adjust the blade rectification arm so as to be closer to each other

The blade is not tensioned Tighten the blade There is

vibration during the cutting

process The material is not placed in a

suitable manner. Place the material in a suitable manner. Material driving reducer chain

gears may loosen. Eliminate the chain space.

The belt, connected to the

encoder, can be loosened. Tension the encoder connection plate. There can be water leakage in the

lower limit switch.

Clean and tighten the switch bolts so that water does not enter.

In NC automatic cutting, the length is not correct

The encoder may have a failure Confirm the driven length by tightening the material in manual operation. The water level is decreased Add water.

The valve and the hoses are

clogged. Clean with the help of pressurized air.

The cutting liquid flow is not sufficient.

The pool and the chip drawer are

919191101 91 The blade tension is not suitable. Bring the blade to the ideal blade

tension. Blade tooth selection is not

suitable.

Select a suitable blade for the material type and the material dimension to be cut. For this, you can contact with the blade dealers or you can contact with the machine technical service. Cutting speed and advancing are

not suitable.

Select the suitable cutting speed and advancing from the blade catalogues used or from the cutting schema on the machine.

The blade is breaking

The directing units at the blade bearings are very tight.

Loosen the directing units. The ideal gap should be equal to 0.1 mm.

9.2 Inverter failure codes and the descriptions thereof

Error Code Contents Probable Reason Things to be done

F0001

High current

1. Motor power, 2. Short circuit in the

motor cable 3. Grounding fault

1. Check if the motor power is compliant with the inverter power.

2. Check if the cable length limits are exceeded or not. 3. Check if there is short circuit and grounding faults in the motor cable and in the motor.

4. Check if the motor parameters are compliant with the used motor or not. 5. Check the resistance of the stator (P0350).

6. Increase the motor revolution raising duration (P1120).

7. Decrease the voltage increase value adjusted in the (P1310), (P1311) and

(P1312) parameters.

8. Check if there is a member which prevents the

functioning of the motor, and check if the motor is

929292101 92 F0002 High voltage

The feeding voltage is out of the tolerance values.

Regenerative load.

1. Check if the feeding voltage is between the limits mentioned on the tag plate. 2. Check if the DC-connection voltage controller (P1240) is active or not and be sure that it is parameterized in the correct manner.

3. Increase the motor revolution decrease duration (P1121).

.F0003 Low voltage

While the inverter is functioning, the main supply is interrupted.

1. Check if the feeding voltage is between the limits mentioned on the tag plate 2. Check if there are short- duration failures or voltage drops in the feeding circuit.

FOO4 High temperature in the

inverter

1. While the equipment is functioning, check if the cooling fan is functioning. 2. Check if the pulse frequency is adjusted to the assumed value or not. 3. The ambient temperature can be above the temperature value which is suitable for the inverter.

4. Check if there is clogging in the air inlet and outlet points. F0005 Inverter I2T 1. Inverter is over-loaded. 1. Check if the load duty cycle

is between the limits or not. F00010 Overheating in the motor

PTC

F00011 Overheating in the motor

1.The motor may be over- loaded.

2. Check the motor tag information.

3. Check the motor l2t warning level parameter. 4. Motor information is erroneous.

1. Check the motor tag information.

2. Consult the service department.

F00021 Grounding error

1.Grounding error at the outlet

2. IGBT failure.

1.Check the grounding errors and correct them.

939393101 93 F00030 Fan cooling is insufficient Fan is faulty

1. The failure can only be masked in case the optional module (not BOP or AOP) is not connected.

2. Consult the service department.

F00041 Motor information presentation error

1. Motor information presentation can not be realized.

Alarm value = 0: no load Alarm value = 1: The current value reaches the limit level.

Alarm value = 2: the defined stator resistance is smaller than 0.1 % or it is greater than 100 %.

Check if the motor is connected to the inverter or

not.

F00051 Parameter EEPROM error

There is error in the reading or writing of the non-volatile parameter memory.

1. Reset to the factory default values and define the

parameters again. 2. Change the inverter. F00052 Contact group failure

The reading process of the contact group information is erroneous or the data is invalid.

Change the inverter.

F00060 Asic Timeout Confirm the failure.

During the time where the telegram is disabled, there is no data for the USS (COMMUNICATION connection)

There is no answer during the TOT duration.

F00080 ADC lost input signal ADC lost input signal F00085 External failure

External failure is triggered by means of the terminal inputs.

For failure triggering, make the terminal input passive. F000101 Contact group overflow Software error or processor

failure

Apply automatic routine tests.

F000221 PID Feedback is below the minimum value

PID Feedback P545 is below the minimum value

1. Change the P545 value. 2. Adjust feedback gain. F000222 PID Feedback is above the

maximum value
