*1. The applicable motor is a 3-phase standard motor. For using any other type, be sure that the rated current does not exceed that of the Inverter.
*2. Output voltage decreases according to the level of the power supply voltage.
*3. The braking torque at the time of capacitor feedback is an average deceleration torque at the shortest deceleration (when it stops from 50 Hz), not a continuous
regeneration torque. Also, the average deceleration torque varies depending on the motor loss. The value is reduced in operation over 50 Hz. Note that no regenerative braking circuit is built into the Inverter. If you need a larger regenerative torque, use the optionally available regenerative braking unit and resistor.
The regenerative braking unit should be used only for short-time regeneration.
*4. Protection method complies with JEM 1030.
*5. To operate the motor at over 50/60 Hz, contact the motor manufacturer to find out the maximum allowable speed of revolution.
*6. For the stable control of the motor, the output frequency may exceed the maximum frequency set in A004 (A204) by 2 Hz max.

●Error Code List
Overcurrent trip
Features
ek_k0k3
Deceleration If the motor is restrained, or rapidly accelerated or decelerated, a large current will flow
through the Inverter, which will result in breakage.
Acceleration To avoid this, an overcurrent protection circuit works to shut off the Inverter output.
Others
ek_k0k4
If the incoming voltage and regenerative energy from the motor are too high, a protection circuit works
to shut off the Inverter output when the voltage on the converter exceeds the specified level.
ek_k0k8
EEPROM error
Shuts off the output if an error occurs in the EEPROM built into the Inverter due to external noise and
abnormal temperature rise.
Check the set data again if the ek_k0k8 error occurs.
If the power is shut off during data initialization, an EEPROM error ek_k0k8 may occur when the power
is next turned on. Shut off the power after completing data initialization.
ek_k0k9
Undervoltage trip
Shuts off the output if the incoming voltage drops below the specified level, causing the control circuit
not to work properly during a momentary power interruption.
ek_k1k1
CPU error
Shuts off the output if the internal CPU has malfunctioned.
If the multi-function output terminal (relay terminal) is set to 05 (alarm), the signal may not be output
during the CPU error ek_k1k1 . In this case, no data is stored in the trip monitor.
The same thing could happen if AL (05) is allocated to the relay output terminal. Again, no data is
stored.
ek_k1k2
External trip
If an error occurs in the external equipment or devices, the Inverter receives the signal, and the output
is shut off.
(Available with the external trip function selected)
ek_k1k3
USP trip
Appears if the Inverter is turned on with the RUN command being input. (Available with the USP
function selected)
If an undervoltage trip ek_k0k9 occurs with the USP terminal set to ON, the trip, after released by
resetting, becomes a USP trip ek_k1k3 . Reset again to release the trip.
ek_k1k4
Ground fault trip
Shuts off the output if a ground fault between the Inverter output unit and the motor is detected when
turning on the power.
The ground fault trip ek_k1k4 cannot be released with the reset input. Shut off the power and check the
wiring.
ek_k1k5
Incoming overvoltage trip
Appears if the incoming voltage has remained high for 100 seconds while the Inverter output is
stopped.
ek_k2k1
Temperature error
Shuts off the output if the temperature has risen in the main circuit due to malfunction of the cooling fan
or other reason.
ek_k3k0
Driver error
Shuts off the output if overcurrent is detected in the main circuit.
ek_k3k5
Thermistor error
While the thermistor input function is used, this detects the resistance of the external thermistor and
shuts off the Inverter output.
ek_k3k7
Emergency shutoff
With the emergency shutoff selected (DIP switch on the control board SW8 = ON), this error appears
when an emergency shutoff signal is input from input terminal 3.
ek_k6k0
Communications error
Occurs when the communication watchdog timer times out.

*1. The applicable motor is a 3-phase standard motor. For using any other type, be sure that the rated current does not exceed that of the Inverter.
*2. Output voltage decreases according to the level of the power supply voltage.
*3. The braking torque at the time of capacitor feedback is an average deceleration torque at the shortest deceleration (when it stops from 50 Hz), not a continuous
regeneration torque. Also, the average deceleration torque varies depending on the motor loss. The value is reduced in operation over 50 Hz. Note that no regenerative braking circuit is built into the Inverter. If you need a larger regenerative torque, use the optionally available regenerative braking unit and resistor.
The regenerative braking unit should be used only for short-time regeneration.
*4. Protection method complies with JEM 1030.
*5. To operate the motor at over 50/60 Hz, contact the motor manufacturer to find out the maximum allowable revolution.
*6. For motor stabilization, the output frequency may exceed the maximum frequency set in A004 (A204) by 2 Hz max.

thermistor trip function is
used)
Detects the resistance of the external thermistor and shuts off the Inverter output.
ek k1k1
If the incoming voltage and regenerative energy from the motor are too high, a protection circuit works
to shut off the Inverter output when the voltage on the converter exceeds the specified level.
*3
Shuts off the output if an error occurs in the EEPROM built into the Inverter due to external noise and
abnormal temperature rise.
ek k2k2
After a trip occurs, normal operation is restored in 10 seconds by resetting.
Check the set data again if the EEPROM error ek k0k8 occurs.
If the power is shut off during data initialization, an EEPROM error ek k0k8 may occur when the power is next turned on. Shut off the power after completing
data initialization or copying.
*4. If an undervoltage trip ek k0k9 occurs with the USP terminal set to ON, the trip, after released by resetting, becomes a USP error ek k1k3 . Reset again
to release the trip.
*5. The ground fault trip ek k1k4 cannot be released with the reset input. Shut off the power and check the wiring.
*6. If the multi-function output (relay output) is set to 05 (alarm), the signal may not be output during the CPU error ek k2k2 . In this case, no data is stored in the trip
monitor.

●Error Code List
Description
Constant
speed
ek0k1.
Monitors the Inverter output current and shuts off the output, displaying an error if the built-in electronic
thermal function detects overload against the motor.
Trips depending on the electronic thermal function settings.
ek0k6.
Braking resistor overload
protection
Shuts off the output and displays an error if the usage rate of regenerative braking circuit exceeds the b090
set value.
Overvoltage protection
Extremely high DC voltage between P/+2 and N/- may result in failure. This function therefore shuts off the
output and displays an error if the DC voltage between P/+2 and N/- exceeds the specified level because of
regenerative energy from the motor or increase of the incoming voltage during operation.
Trips when the DC voltage between P/+2 and N/- reaches approximately 400 V DC for 200-V class, and 800
V DC for 400-V class.
EEPROM error *2
Shuts off the output and displays an error if an error occurs because of external noise and abnormal
temperature rise in the EEPROM built into the Inverter.
Note: It may become a CPU error depending on the case.
ek0k4.
ek0k7.
ek0k8.
*3
Shuts off the output if an error occurs in the CT (current detector) built into the Inverter. Trips if the CT output
is approximately 0.6 V or more when the power is turned on.
ek1k1.
CPU error *3
Shuts off the output and displays an error if the internal CPU has worked erroneously or abnormally.
Note: If an abnormal value is read from EEPROM, it may become a CPU error depending on the case.
ek1k2.
External trip
If an error occurs in the external equipment or devices, the Inverter receives the signal, and the output is shut
off. (Available with the external trip function selected)
ek1k3.
USP error
Appears when the power is turned on with the RUN signal input into the Inverter.
(Available with the USP function selected)
ek1k4.
Grounding protection *3
Protects the Inverter if a ground fault between the Inverter output unit and the motor is detected when turning
on the power. (This function does not work when there is residual voltage in the motor.)
Incoming overvoltage
protection
Appears if the incoming voltage continues to be higher than the specification value for 100 seconds while the
Inverter is stopped.
Trips when the main circuit DC voltage reaches approximately 390 V DC for 200-V class, and 780 V DC for
400-V class.
ek1k6.
Momentary power
interruption protection
Shuts off the output when a momentary power interruption occurs for 15 ms or more.
If the shutoff time is long, it is normally recognized as a power shutoff. Note that, when restart is selected, the
Inverter restarts from recovery as long as the RUN command remains.
ek2k0.
Temperature error when
the rotation speed of the
cooling fan decreases
Appears if a decrease of the cooling fan rotation speed has been detected when the following temperature
error occurs.
ek2k1.
Temperature error
Shuts off the output if the temperature has risen in the main circuit because of the high ambient temperature.
ek2k3.
Gate array communications
error
Trips when a fault is detected in communication behavior between the built-in CPU and the gate array.
ek2k4.
Input open-phase
protection
Prevents Inverter damage due to input open-phase protection function when the input open-phase selection
is enabled (b006=01), and trips.
Trips when the open-phase time is approximately 1 s or more.
ek2k5.
Main circuit error *3
Trips when the gate array cannot confirm IGBT ON/OFF because of erroneous operation or main element
breakage caused by noise interfusion.
ek3k0.
IGBT error
Shuts off the Inverter output to protect the main element when a momentary overcurrent, temperature error in
the main element, or drop of the main element driving power supply occurs.
(Retry operation cannot be performed after this trip.)
ek3k5.
Thermistor error
Shuts off the Inverter output when detecting the thermistor resistance value inside the motor connected to
the TH terminal and resulting motor temperature rise.
ek3k6.
Brake error
When 01 is selected in b120 (brake control selection), this error appears if the brake ON/OFF cannot be
recognized within the b124 set time (brake confirmation wait time) after the Inverter outputs the brake release
signal.
ek3k7.
Emergency shutoff *4
Shuts off the hardware output and displays an error when the EMR terminal (S3) is turned on with SW1 on
the logic board ON.
ek3k8.
Overload protection in a
low speed range
If an overload is detected in the lowest speed range of 0.2 Hz max., an electronic thermal inside the Inverter
works to shut off the Inverter output. (2nd electronic thermal level)
(However, higher frequency could remain in the error history.)
ek4k1.
Modbus communications
error
Appears when the timeout occurs because of disconnection during Modbus-RTU communication.
(Trip by the C076 setting)

Features
Overcurrent protection
If the motor is restrained or rapidly accelerated or decelerated, a large current will flow through
the Inverter, which will result in breakage. The larger than specified current then shuts off the
Deceleration output and an error appears.
The protection detects this overcurrent through AC CT (current detector).
Acceleration The protection circuit operates at approximately 220% of the Inverter rated output current and
a trip occurs.

Description
*1. The reset command will not be accepted until approximately 10 seconds pass since the trip occurs (protection function works)
*2. The reset command will not be accepted if the EEPROM error ek0k8. occurs. Turn off the power once. If you find E08 when turning on the power again, it is
possible that the memory element has been broken or the parameters have not been memorized correctly. Perform the user initialization to set the parameters
again.
*3. The reset command through the RS terminal or STOP/RESET key will not be accepted. Turn off the power.
*4. The reset operation via the Digital Operator will not be accepted. Be sure to reset via the RS terminal.

Overview of Inverter Selection
Selecting the Motor Capacity
Select a motor before selecting the Inverter. Calculate the load
inertia in the application, calculate the motor capacity and torque
required to handle the load, and select an appropriate motor.
■ Simple Selection Method
(Calculation of the Required Output)
With this method, you select the motor based on the output (W)
required when the motor is rotating at a steady rate. This method
does not include the involved calculations for acceleration and
deceleration, so add some extra capacity to the calculated value
when selecting the motor. This is a simple way to calculate the
size of motor needed in equipment that operates at a steady rate
for long periods, such as fans, conveyors, and mixing machines.
This method is not suitable for the following kinds of applications:
•Applications requiring sudden start-ups
•Applications where the equipment starts and stops frequently
•Applications where there is a lot of inertia in the transmission
system
•Applications with a very inefficient transmission system
● Calculating the Motor Shaft Conversion Inertia
Use the following equations to calculate the inertia of all of the
parts and convert that to the motor shaft conversion inertia.

Overview of Inverter Selection
Overview of Braking Resistor Selection
■ Applications Requiring Braking Resistors
■ Simple Method for Braking Resistor Selection
In applications where excessive regenerative motor energy is
produced during deceleration or descent, the main-circuit voltage in the Inverter may rise high enough to damage the Inverter.
Standard Inverters are equipped with an overvoltage protection
function so the main-circuit overvoltage (OV) is detected and
operation is stopped to prevent damage. Although the Inverter
will be protected, the overvoltage protection function will generate an error and the motor will stop; this system configuration will
not provide stable continuous operation.
This is a simple method for determining the braking resistance
from the percentage of time that regenerative energy is produced
during a normal operating pattern.
t
● About Regenerative Energy
T
The load connected to the motor has kinetic energy if it is rotating or potential energy if it is at a high level. The kinetic or potential energy is returned to the Inverter when the motor decelerates
or lowers the load. This phenomenon is known as regeneration
and the returned energy is called regenerative energy.
Inverter
Motor
Load
Kinetic energy
Potential energy
Regenerative
energy
During deceleration, the Inverter acts as
a generator and converts kinetic and
potential energy to regenerative energy.
● Avoiding the Use of a Braking Resistor
The following methods can be used to avoid having to connect a
Braking Resistor. These methods require the deceleration time
to be extended, so you must evaluate whether extending the
deceleration time will cause any problems in the application.
• Enable the "stall prevention during deceleration" function; the
default setting for this function is enabled. (The deceleration
time is extended automatically to prevent main-circuit overvoltage from occurring.)
• Set a longer deceleration time. (This reduces the rate at which
the regenerative energy is produced.)
• Select "coast to stop" as the stopping method. (Regenerative
energy will not be returned to the Inverter.)
60
Overview of Inverter Selection
Use rate (duty) = t/T x 100 (%ED)
t: Deceleration time (regenerative time)
T: Time for 1 cycle of operation
Overview of Inverter Selection
If the Braking Resistor's use rate (duty factor) exceeds 10% ED
or the application requires an extremely large braking torque,
use the following method to calculate the regenerative energy
and select a Braking Resistor.
Energy at max. speed N (r/min):
The kinetic energy is proportional
to the square of the speed, so the
regenerative energy is highest
momentarily at this point.
Speed
Max deceleration torque T (kgf•cm):
Regenerative energy is produced
when the motor's direction is
opposite the motor torque direction.
Braking Resistor’s resistance: R ≤
V2
1.048 x (T-0.2 x Tm) x N x 10-1
Note 1. The internal braking transistor will be damaged if a resistor is connected
with a resistance below the Inverter or Braking Unit's minimum resistance. If the required resistance is less than the minimum resistance, increase the Inverter's capacity and replace the Inverter or Braking Unit
with one that has a minimum resistance less than the required resistance.
2. Two or more Braking Units can be connected in parallel. Use the following equation to determine the braking resistance when driving two or
more Units.
Braking resistance (Ω) = (required braking resistance calculated above)
× (number of Units)
3. Do not select the braking resistance with the results calculated above.
A rating of 150 W is not the allowed power, it is the maximum rated power in resistance units. The actual allowed power rating depends upon
the resistor.
