3. Trouble Shoot

3-1. Error Messages - Possible Cause and Remedy:

(1) Over current 1 (E 01, E 02, E 03, E 04)

Phenomena: Over current (CT or Rsh;gate driver IC) for each condition.

E 01 : Over current during constant speed operation. E 02 : Over current during deceleration. E 03 : Over current during acceleration. E 04 : Over current at other condition than above mentioned.

(such as injection brake)

Cause: Load changed rapidly. Remedy: Eliminate rapid changed in load.

Cause: Sort circuit or earth contact (ground fault) in the motor or the motor cable. Remedy: Check with Megger. If the motor cable is disconnected from the inverter, the over

current should not be detected anymore.

Cause: A single-phase power failure (fuse, wire, ...) can cause a shutdown in certain

under load situations..

Remedy: Check all these mains phases and the mains fuses, preferably by comparison of

the three (two in case of single phase inverter) mains currents in a steady operating state.

Cause: The motor is switched with a motor contactor during frequency inverter operation.

Remedy: Switching over the motor is inhibited.

Cause: Defect in the power component. Remedy: Check the IGBT portion of ISPM.

Cause: Rapid acceler ation or deceleration. Remedy: Set suitable acceleration or deceleration time.

Cause: St arting frequency is too high. Remedy: Set starting frequency as low as possible.

Way to Reset: A

SJ100 has two kinds of detection; CT and Rsh. To resolve the detection at site, check the following

procedure.

1. Connect DOP/DRW.

2. Set F38 INIT DEBG ON. (to access debug mode)

3. Set F22 IPS POWR ALM mode, don’t set retry mode.

4. Test run and wait Over Current trip.

5. Set Core address “FBE4” if it’s 4kW or less.

5. Set Core address “FBE2” if it’s 5.5kW or above.

3-1

Specimen ; “CO FBE4 01 0000” ; under normal; 0Hz “CO FBE4 15 0203” ; under over.C trip “CO FBE4 15 C203” ; under OC.Drive trip. “CO FBE4 15 4103” ; under OC.Accel trip

“FBE4” or “FBE2” is 1 byte data, the data is hex data. Example “4103”; “03” has no meaning. Resolve “41”h bit by bit, “41”h -> “0100 0001”b if you found “xxxx xxx1” ; this means Over current detection from CT (CTU or CTW) if you found “xxxx xx1x” ; this means Over current detection from Rsh

Standard operator is not available on this trouble shooting.

(2) Overload (E 05)

Phenomena: Overload (detected by CT) of the inverter.

This error can be reset 10 seconds after the E05 came out.

Cause: Motor load is heavy. Remedy: Reduce the load and/or increase thermal level and/or use bigger capacity of

frequency inverter.

Cause: V- Boost value is high. Remedy: Reduce V-Boost value or increase thermal level and/or use bigger capacity of

frequency inverter.

Cause: Set wrong value for electronic thermal level [b12] and/or electronic thermal

characteristic [b13].

Remedy: Set suitable value. Cause: Set wrong value for the reactive current of the motor.

Remedy: Set suitable value. Reactive current value which should be input by function mode

is a value measured at 50Hz (60Hz) without load.

Way to Reset: A

(3) Braking Resistor Overload (over voltage) (E 06)

Phenomena: Over Voltage detection after BRD%ED was run out. Cause: BRD select ion is not suitable.

Remedy: Check BRD %ED, BRD resistor ohm, BRD resistor W attage, BRD resistor wire,

machine inertial, operation cycle.

Way to Reset: A

3-2

(4) Over voltage (E 07)

Phenomena: Over voltage at DC bus line of the frequency inverter. Cause: Mains voltag e too high, mains voltage fluctuation or rapid mains voltage return

(choke energy leads to voltage increase).

Remedy: Make sure that mains voltage is within tolerance limits. Cause: In case SJ100 is used in combination with a regenerative braking unit(ISPM)/

resistor but the regenerative braking unit(ISPM)/resistor does not function.

Remedy: Replace regenerative braking unit(ISPM)/resistor. Cause: In case SJU100 is used in combination with a raking resistor but the braking

resistor cannot absorb the regenerative energy.

Remedy: Re-calculate and use suitable braking resistor. Cause: Deceler ation time is too short.

Remedy: Make deceleration time longer, use braking unit (resistor), use bigger capacity of

frequency inverter.

Way to Reset: A

(5) Under voltage (E 09)

Phenomena: Under voltage at DC bus line of the frequency inverter. Cause: The mains voltage is not available or not within the tolerance limits.

Remedy: Check all 3 (or 2) mains power supply voltage that it is within its specification. Cause: T hyristor for smooth charging is defect and DC bus voltage drops while operation

due to current flows through smooth charging resistor. Remedy: Change ISPM. Cause: Period of instantaneous power failure is longer than the set value [b02], or DC bu s

voltage go down to its detecting level while instantaneous power failure. Remedy: Get rid of the instantaneous power failure, evaluate the power supply system, set

bigger value for [b02].

Cause: O ne of the AC voltage is missing (applied only for 3 phase INV) Remedy: Check AC line voltage , check the fuses.

Way to Reset: A

(6) EEPROM error (E 08)

Phenomena: Abnormal situation occurs at the memory portion of the frequency inverter due to

incoming noise etc..

Cause: I nfluenced by Electrical Magnetic Interference. Remedy: Keep such noise source away from the frequency inverter.

Cause: Am bient temperature is too high. Remedy: Take countermeasure against high ambient temperature.

3-3

Cause: Re- power up the frequency inverter short time after power off. It is necessary to

keep several seconds after power off to memorize the current data at EEPROM. If

this time is too short, this storage performance cannot be done and leads to

EEPROM error. Remedy: Keep certain time between power off and re-power up.

Cause: You didn’t wait 6 seconds or more at FACTORY SETTING. Remedy: Please try FACTORY SETTING again.

Cause: RS t erminal was keeping “ON” at power off. (If RS is on, INV can not write the

correct data to EPROM at power off, next power on E08 will come out.) Remedy: Please don’t use “RS” terminal “ON” at power off.

Cause: EEPRO M is def ect. Remedy: Change unit.

After you reset the INV, please make sure the parameters espec ially maximum freq. / A cc /Dec

time / Low limit freq. to prevent any damage.

Way to Reset: A or Power off

(7) CT error (E 10)

Phenomena: When abnormality noise is near the INV or an abnormality (off set level is out of

spec.) occurs on built in CT.

Cause: I nfluenced by Electrical Magnetic Interference. (such as near contactor on/off) Remedy: To Resolve if it’s influence, use another power line and don’t connect motor wires,

control wires. If no error comes out, resolve noise causes. Cause: CT offset level failure

Remedy: To Resolve if it’s failure, use another power line and power on and check if E10

comes out at power on. If E10 came out , use (replace) another INV(ISPM).

Way to Reset: A or Power off

(8) CPU error (E 11, E 22)

Phenomena: Abnormal situation or malfunction of micro processor inside frequency inverter.

E 11 : CPU error from MCU inside core.

E 22 : CPU error from MCU on I/O board.

E22 is produced by MCU on I/O board and the causes is communication error between ISPM & M CU

on I/O board.

Cause: Cable ( between ISPM and I/O board)was cut. (E22) Remedy: Replace the cable.

Cause: Dust s on the pins of CN2 on I/O board. (E22) Remedy: Remove the dusts.

Cause: I nfluenced by Electrical Magnetic Interference. Remedy: Keep such noise source away from the frequency inverter.

Cause: Am bient temperature is too high. Remedy: Take countermeasure against high ambient temperature.

3-4

Cause: Com ponent itself is defect. Remedy: Replace ISPM (in case of E 11) or I/O board board (in case of E 12).

(9) External Trip (E 12)

Phenomena: Trip due to have inputted an external signal to “EXT” input terminal of the

frequency inverter.

Cause: Fault y external device or equipment gives frequency inverter a trip requirement

when external trip function (EXT) is selected. Remedy: Evaluate external device or equipment which is connected to frequency inverter.

Way to Reset: A

(10) USP error (E 13)

Phenomena: Unexpected Start Protection. This error can occur when “USP” function is

selected. Cause: Fr eq uency inverter trips when it is powered up with RUN command is given.

Remedy: Disable RUN command when power up the frequency inverter. Or disable USP

function if possible to the system.

Way to Reset: A or set RUN command off (stop)

(11) Ground fault error (E 14)

Phenomena: Earth contact in the motor or the motor cable or in the IGBT. Frequency inverter

detects this earth contact only at power up.

To resolve the causes , please power off and disconnect the motor wire at INV (UVW)terminal.

Cause: Ear th contact in the motor or the motor cable. Remedy: Check the impedance between output portion(wire and motor) and earth.

Cause: Det e ct ion circuit /IGBT of the inverter is defect. If the m otor and t he mot or cable is

disconnected from the frequency inverter, the ground fault should not be detected

anymore. Remedy: Please disconnect the motor and the motor cable.

If E14 comes out at power on, please replace the unit.

Way to Reset: Don’t reset.

(12) Over voltage at source (E 15)

Phenomena: High voltage at power source line. Frequency inverter cannot protect source over

voltage. If it is too high, frequency inverter will be damaged. Cause: Sour ce voltage is too high.

Remedy: Check the source voltage continously.

Insert AC reactor at source lines.

Way to Reset: A

3-5

(13) Over temperature (E 21)

Phenomena: Temperature sensor which located close to IGBT inside ISPM shows a too high

temperature. Cause: Vent ilator blocked. (for models which has ventilator.)

Remedy: Check ventilator Cause: The frequency inverter does not get enough cooling air.

Remedy: Check cabinet ventilation, air filters, and ventilation openings in the cabinet.

Way to Reset: A

(14) PTC error (E 35)

Phenomena: Resistance of motor thermistor is high. This error can occur when you select

“PTC” function. Cause: Too much load of the motor.

Remedy: Reduce the load, use bigger motor. Cause: Motor t hermist or is not connected while PTC function is selected.

Remedy: Disable PTC function when it is not used. Cause: Char acteristics of the motor thermistor is not suitable. Frequency inverter gives

PTC error when the resistance value becomes more than 3k ohm +-10%. Remedy: Use motor which has suitable thermistor for the inverter.

Or change thermistor characteristics of the thermistor by debug mode.

Way to Reset: A

Explanation of the way to reset.

A : Make close the terminals between RS and P24 (CM1 only for Japanese version) on the I/O board, or

press “STOP/RESET” key of the operator.
