3. Trouble Shoot
3-1. Error Messages - Possible Cause and Remedy:
(1) Overcurrent 1 (E 01, E 02, E 03, E 04)
Phenomena: Overcurrent for each condition.
E 01 : Overcurrent during constant speed operation.
E 02 : Overcurrent during deceleration.
E 03 : Overcurrent during acceleration.
E 04 : Overcurrent 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
overcurrent should not be detected anymore.
Cause: A single-phase power failure (fuse, wire, ...) can cause a shutdown in certain
underload 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 acceleration or deceleration.
Remedy: Set suitable acceleration or deceleration time.
Cause: Starting frequency is too high.
Remedy: Set starting frequency as low as possible.
Way to Reset: A
3-1
(2) Overload (E 05)
Phenomena: Overload 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) Overvoltage (E 07)
Phenomena: Overvoltage at DC bus line of the frequency inverter.
Cause: Mains voltage 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 L100 is used in combination with a regenerative braking unit but the
regenerative braking unit does not function.
Remedy: Replace regenerative braking unit.
Cause: In case L100 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: Deceleration time is too short.
Remedy: Make deceleration time longer, use braking unit (resistor), use bigger capacity of
frequency inverter.
Way to Reset: A
(4) Undervoltage (E 09)
Phenomena: Undervoltage 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: Thyristor for smooth charging is defect and DC bus voltage drops while operation
due to current flows through smooth charging resistor.
Remedy: Change ISPM. 3-2
Cause: Period of instantaneous power failure is longer than the set value [b02], or DC bus
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: One of the AC voltage is missing (applied only for 3 phase INV)
Remedy: Check AC line voltage , check the fuses.
Way to Reset: A
(5) EEPROM error (E 08)
Phenomena: Abnormal situation occurs at the memory portion of the frequency inverter due to
incoming noise etc..
Cause: Influenced by Electrical Magnetic Interference.
Remedy: Keep such noise source away from the frequency inverter.
Cause: Ambient temperature is too high.
Remedy: Take countermeasure against high ambient temperature.
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 terminal 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: EEPROM is defect.
Remedy: Change unit.
After you reset the INV, please make sure the parameters especially maximum freq. / Acc /Dec
time / Low limit freq. to prevent any damage.
Way to Reset: Aor Power off
(6) 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 & MCU
on I/O board.
Cause: Cable (between ISPM and I/O board)was cut. (E22)
Remedy: Replace the cable.
Cause: Dusts on the pins of CN2 on I/O board. (E22)
Remedy: Remove the dusts.
3-3
Cause: Influenced by Electrical Magnetic Interference.
Remedy: Keep such noise source away from the frequency inverter.
Cause: Ambient temperature is too high.
Remedy: Take countermeasure against high ambient temperature.
Cause: Component itself is defect.
Remedy: Replace ISPM (in case of E 11) or I/O board board (in case of E 12).
(7) External Trip (E 12)
Phenomena: Trip due to have inputted an external signal to “EXT” input terminal of the
frequency inverter.
Cause: Faulty 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
(8) USP error (E 13)
Phenomena: Unexpected Start Protection. This error can occur when “USP” function is
selected.
Cause: Frequency 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)
(9) 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: Earth contact in the motor or the motor cable.
Remedy: Check the impedance between output portion(wire and motor) and earth.
Cause: Detection circuit/IGBT of the inverter is defect. If the motor and the motor 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.
3-4
(10) Over voltage at source (E 15)
Phenomena: High voltage at power source line. Frequency inverter cannot protect source
overvoltage. If it is too high, frequency inverter will be damaged.
Cause: Source voltage is too high.
Remedy: Check the source voltage continously.
Insert AC reactor at source lines.
Way to Reset: A
(11) Over temperature (E 21)
Phenomena: Temperature sensor which located close to IGBT inside ISPM shows a too high
temperature.
Cause: Ventilator 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
(12) 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 thermistor is not connected while PTC function is selected.
Remedy: Disable PTC function when it is not used.
Cause: Characteristics 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.

4-2. Required derating toward altitude
Example of calculation
L100-007NFE (4 Amps) is installed at 2000m of altitude and 16kHz of carrier frequency.
Required derating of output frequency of this case will be as follows.
4 [Amps] * 90% * 95% = 3.4 [Amps]
<Note 1> When the top cover is removed for the high ambient temperature, inverter should be installed
in an enclosure of IP 4* (see EN60529) to comply with LVD directive.
<Note 2> If class B of EMC directive is required, carrier frequency must be set to 5kHz.

5-2. Output Current Detection Characteristics
Frequency inverter has several detection characteristics for output current to protect IGBT from break
down, or to protect motor from over heat.
[1] Over current
Frequency inverter shuts off the output instantaneously when output current exceeds to 200% of its
rated current.
e.g. Over current protection level of L100-015NFE (7.1 Amps of rated current) is
7.1 [Arms] * 200% = 14.2 [Arms] = 20.1 [A peak]
[2] Over load (Electronic thermal protection)
Frequency inverter shuts off the output when integration value of output current and time exceeds
specific value.
This Electronic thermal level can be changed from 50% to 120%. (Initial setting is 100%.)

6. Measurement & Replacement of Subassemblies
6-1. Insulation Measurement
For L100 inverter, do not perform insulation measurements , otherwise MOV will be damaged.
(MOV; between R(L1)-G, S(L2)-G, T(L3)-G)
6.2. Power Components Measurements.
When checking the power components, the following procedure is recommended:
z Clear voltage
z Wait for capacitors discharge
z Check capacitors for neutrality
z Disconnect mains and motor wires
z Test the diodes and IGBTs using a universal tester with a diode function.
Visual check is important for the ISPM, check the outlooking such as smoke trace.
Note: In this test, the absolute values are not so important, since they depend strongly on the test
device used. The uniformity of the measured value is more important.

7. Maintenance and Inspection Procedure
7-1. Precautions
(1) Maintenance and Inspection Precautions
Be sure to check the followings before starting maintenance and inspection because there is a
danger of electrical shock.
z Display on the digital operation panel and POWER indication has been turned OFF.
z The voltage between + and - is 15Vdc or lower.
z Discharging resistor (500 ohm 30W for 200V class, 1k ohm 60W for 400V class) has been
connected between + and - terminals for 15 seconds or more after main power had turned off,
(2) General Precautions
z Always keep the unit clean so that no dust nor other foreign materials come inside of the
frequency inverter.
z Pay attention to broken lines and faulty connections. Firmly connect terminals and connectors.
z Keep frequency inverter away from moisture and oil.
z Dusts, steel filings , swarf , and other foreign materials can damage insulation and causing
unexpected accidents/failure. Please pay attention to them.
7-2. Measurement of Mains Voltage, Current and Power
General measuring instruments for mains voltage, current and power are shown in Table 7-1.
The voltage to be measured is the effective value of fundamental wave, and the power to be measured
is the total effective value.
(1) Measurement of output voltage
Moving iron type instrument does not show accurate values for measurement of the output voltage.
Make measurements according to the method shown in Fig. 7-3 (table 7-1) or using the circuit
indicated in Fig. 7-1 and 7-2.

When there is no motor connected to the inverter, please use additional resistor like Fig. 7-2. There
will be a voltage at output terminal even the frequency command is naught due to the leakage current
of the semiconductor devices.
(2) Measurement of Input voltage and Input / output current
Use moving iron type ampere meter. (Refer to Fig. 7-3 and Table 7-1.)
(3) Measurement of Input and output power
Use electrodynamics type watt meter for single phase use. Make measurements for all 3 phases is
case there is an unbalance in voltages and currents.

7-3. Maintenance of Parts
(1) Maintenance of printed circuit board (I/O board)
Printed circuit boards are maintenance free under normal applications except ALARAM relay
(hardware). However, in case which maintenance and inspection are necessary, pay attention to
the prevention of damage caused by static electricity as shown below.
* Prevent damage caused by static electricity
MCU and LSI on the printed circuit board can be destroyed by static electricity. Therefore be
sure to ground work benches, soldering irons and yourself before start working on a printed
circuit board.
(2) Maintenance of DC bus capacitor and cooling fan
We recommend that DC bus capacitors and cooling fans to be regularly replaced every three years
taking their lives into account. Please note that their life span shorten when they are used in high
temperatures and heavy loads.
7-4. If you install replacement INV at site
If you install replacement units at site, please preset the parameter by the panel or copy unit.
If you used the previous I/O board to replacement unit, the parameters are not changed.
Because parameters are memorized in the EEPROM on the control board on J100 /J300 series, and if
we used the previous control board to replacement unit at site to minimize the time. In case of
L100,SJ100 series, EEPROM is on the ISPM, even we replaced I/O board, the parameter is still the
same.
