Warnings
CAUTION
Cables must not be connected or disconnected, nor signal tests carried out, while the power is
switched on.
The Varispeed DC bus capacitor remains charged even after the power has been switched off. To
avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out
maintenance. Then wait for at least 5 minutes after all LEDs have gone out.
Do not perform a withstand voltage test on any part of the Varispeed. The frequency inverter contains
semiconductors, which are not designed for such high voltages.
Do not remove the digital operator while the mains supply is switched on. The printed circuit board
must also not be touched while the inverter is connected to the power.
Never connect general LC/RC interference suppression filters, capacitors or overvoltage protection
devices to the inverter input or output.
To avoid unnecessary overcurrent faults, etc, being displayed, the signaling contacts of any contactor
or switch fitted between inverter and motor must be integrated into the inverter control logic (eg
baseblock).
This is absolutely imperative!
This manual must be read thoroughly before connecting and operating the inverter. All safety
precautions and instructions for use must be followed.
The inverter may must be operated with the appropriate line filters, following the installation
instructions in this manual and with all covers closed and terminals covered.
Only then will adequate protection be provided. Please do not connect or operate any equipment with
visible damage or missing parts. The operating company is responsible for any injuries or equipment
damage resulting from failure to heed the warnings in this manual.
VII
Safety Precautions and Instructions for Use!
1. General
Please read these safety precautions and instructions for use thoroughly before installing and operating this
inverter. Also read all of the warning signs on the inverter and ensure they are never damaged or removed.
Live and hot inverter components may be accessible during operation. Removal of housing components, the
digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installation or operation. The fact that frequency inverters control rotating mechanical machine components can give
rise to other dangers.
The instructions in this manual must be followed. Installation, operation and maintenance may only be carried
out by qualified personnel. For the purposes of the safety precautions, qualified personnel are defined as individuals who are familiar with the installation, starting, operation and maintenance of frequency inverters and
have the proper qualifications for this work. Safe operation of these units is only possible if they are used
properly for their intended purpose.
The DC bus capacitors can remain live from about 5 minutes after the inverter is disconnected from the power.
It is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may
still carry dangerous voltages.
Children and other unauthorized persons must not be allowed access to these inverters.
Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all persons with
any form of access to the inverters.
2. Intended Use
Frequency inverters are intended for installation in electrical systems or machinery.
Their installation in machinery and systems must conform to the following product standards of the Low Voltage Directive:
EN 50178, 1997-10,
Equipping of Power Systems with Electronic Devices
EN 60204-1, 1997-12 Machine Safety and Equipping with Electrical Devices
Part 1: General Requirements (IEC 60204-1:1997)/
Please note: Includes Corrigendum of September 1998
EN 61010-1, A2, 1995 Safety Requirements for Information Technology Equipment
(IEC 950, 1991 + A1, 1992 + A2, 1993 + A3, 1995 + A4, 1996, modified)
CE marking is carried out to EN 50178, using the line filters specified in this manual and following the appropriate installation instructions.
3. Transportation and storage
The instructions for transportation, storage and proper handling must be followed in accordance with the technical data.
4. Installation
Install and cool the inverters as specified in the documentation. The cooling air must flow in the specified
direction. The inverter may therefore only be operated in the specified position (eg upright). Maintain the
specified clearances. Protect the inverters against impermissible loads. Components must not be bent nor insulation clearances changed. To avoid damage being caused by static electricity, do not touch any electronic
components or contacts.
VIII
5. Electrical Connection
Carry out any work on live equipment in compliance with the national safety and accident prevention regulations. Carry out electrical installation in compliance with the relevant regulations. In particular, follow the
installation instructions ensuring electromagnetic compatibility (EMC), eg shielding, grounding, filter
arrangement and laying of cables. This also applies to equipment with the CE mark. It is the responsibility of
the manufacturer of the system or machine to ensure conformity with EMC limits.
Your supplier or Yaskawa representative must be contacted when using leakage current circuit braker in conjunction with frequency inverters.
In certain systems it may be necessary to use additional monitoring and safety devices in compliance with the
relevant safety and accident prevention regulations. The frequency inverter hardware must not be modified.
6. Notes
The VARISPEED F7 frequency inverters are certified to CE, UL, and c-UL.
IX
EMC Compatibility
1. Introduction
This manual was compiled to help system manufacturers using YASKAWA frequency inverters design and
install electrical switchgear. It also describes the measures necessary to comply with the EMC Directive. The
manual's installation and wiring instructions must therefore be followed.
Our products are tested by authorized bodies using the standards listed below.
Product standard:
EN 61800-3:1996
EN 61800-3; A11:2000
2. Measures to Ensure Conformity of YASKAWA Frequency inverters to the EMC Directive
YASKAWA frequency inverters do not necessarily have to be installed in a switch cabinet.
It is not possible to give detailed instructions for all of the possible types of installation. This manual therefore
has to be limited to general guidelines.
All electrical equipment produces radio and line-borne interference at various frequencies. The cables pass
this on to the environment like an aerial.
Connecting an item of electrical equipment (eg drive) to a supply without a line filter can therefore allow HF
or LF interference to get into the mains.
The basic countermeasures are isolation of the wiring of control and power components, proper grounding and
shielding of cables.
A large contact area is necessary for low-impedance grounding of HF interference. The use of grounding
straps instead of cables is therefore definitely advisable.
Moreover, cable shields must be connected with purpose-made ground clips.
3. Laying Cables
Measures Against Line-Borne Interference:
Line filter and frequency inverter must be mounted on the same metal plate. Mount the two components as
close to each other as possible, with cables kept as short as possible.
Use a power cable with well-grounded shield. Use a shielded motor cable not exceeding 20 meters in length.
Arrange all grounds so as to maximize the area of the end of the lead in contact with the ground terminal (eg
metal plate).
Shielded Cable:
– Use a cable with braided shield.
– Ground the maximum possible area of the shield. It is advisable to ground the shield by connecting the
cable to the ground plate with metal clips (see following figure).
X
Ground clip
Ground plate
The grounding surfaces must be highly conductive bare metal. Remove any coats of varnish and paint.
– Ground the cable shields at both ends.
– Ground the motor of the machine.

Circuit Descriptions
1. Control circuit terminals are arranged as shown below.
IMPORTANT
2. The output current capability of the +V terminal is 20 mA.
Disable the stall prevention during deceleration (L3-04 = 0) or set it to enabled with Braking Resistor Unit
(L3-04 = 3) when using a Braking Option. If this user constant is not changed to disable stall prevention,
the system may not stop within set deceleration time.
Set parameter L8-01 to 1 when using a breaking resistor that is to be mounted to the backside of the
inverters heatsink (ERF-type). When using a Braking Resistor Unit, a shutoff control circuit for the power
supply has to be installed using a thermal overload relay trip contact.
3. Main circuit terminals are indicated with double circles and control circuit terminals are indicated with single circles.
4. The wiring of the digital inputs S1 to S7 is shown for the connection of contacts or NPN transistors (0V
common and sinking mode). This is the default setting.
For the connection of PNP transistors or for using a 24V external power supply, refer to Table 2.14.
5. The master speed frequency reference can be input either at terminal A1 or at terminal A2 by changing
the setting of parameter H3-13. The default setting is terminal A2.
6. The multi-function analog outputs are dedicated meter outputs for analog frequency meters, ampmeters,
voltmeters, wattmeters, etc. Do not use these outputs for feedback control or for any other control purposes.
7. DC reactors to improve the input power factor are built into 200 V Class Inverters from 22 up to 110 kW
and 400 V Class Inverters from 22 up to 300 kW. A DC reactor is an option only for Inverters of 18.5 kW
or less. Remove the short circuit bar when connecting a DC reactor.

Wiring Main Circuit Terminals
Installing a Molded-case Circuit Breaker
When connecting the power input terminals (R/L2, S/L2, and T/L3) to the power supply using a molded-case
circuit breaker (MCCB) observe that the circuit breaker is suitable for the Inverter.
• Choose an MCCB with a capacity of 1.5 to 2 times of the inverter's rated current.
• For the MCCB's time characteristics, be sure to consider the inverter's overload protection (one minute at
150% of the rated output current).
Installing a Ground Fault Interrupter
Inverter outputs use high-speed switching, so high-frequency leakage current is generated. If a ground fault
interrupter should be used, select an interrupter that detects only the leakage current which is in the frequency
range that is hazardous to humans but not high-frequency leakage currents.
• For the special-purpose ground fault interrupter for Inverters, choose a ground fault interrupter with a sen-
sitivity amperage of at least 30 mA per Inverter.
• When using a general ground fault interrupter, choose a ground fault interrupter with a sensitivity amper-
age of 200 mA or more per Inverter and with an operating time of 0.1 s or more.
Installing a Magnetic Contactor
If the power supply for the main circuit is to be shut off by a control circuit, a magnetic contactor can be used.
The following things should be considered:
• The Inverter can be started and stopped by opening and closing the magnetic contactor on the primary side.
Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down.
Start and stop the Inverter at most once every 30 minutes.
• When the Inverter is operated with the Digital Operator, automatic operation cannot be performed after
recovery from a power interruption.
• If a Braking Resistor Unit is used, design the control circuit so that the magnetic contactor is turned OFF
by the contact of the Unit's thermal overload relay.
Connecting Input Power Supply to the Terminal Block
Input power supply can be connected to any terminal R, S or T on the terminal block; the phase sequence of
input power supply is irrelevant to the output phase sequence.
Installing an AC Reactor
If the Inverter is connected to a large-capacity power transformer (600 kW or more) or a phase advancing
capacitor is switched, an excessive peak current may flow through the input power circuit, causing the inverter
unit to break down.
To prevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactor to the DC reactor connection terminals.
This also improves the power factor on the power supply side.
Installing a Surge Absorber
Always use a surge absorber or diode for inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.
Wiring the Output Side of Main Circuit
Observe the following precautions when wiring the main output circuits.
2-15
Connecting the Inverter and Motor
Connect output terminals U/T1, V/T2, and W/T3 respective to the motor lead wires U, V, and W.
Check that the motor rotates forward with the forward run command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the forward run command.
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals U/T1, V/T2, and W/T3. If voltage is applied to the output
terminals, the internal circuits of the Inverter will be damaged.
Never Short or Ground Output Terminals
If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding may occur. This is extremely hazardous. Do not short the output wires.
Do Not Use a Phase Advancing Capacitor
Never connect a phase advancing capacitor to an output circuit. The high-frequency components of the
Inverter output may overheat and be damaged and may cause other parts to burn.
Do Not Use an Electromagnetic Switch
Never connect an electromagnetic switch (MC) between the Inverter and motor and turn it ON or OFF during
operation. If the MC is turned ON while the Inverter is operating, a large inrush current will be created and the
inverter’s overcurrent protection will operate.
When using a MC to switch for instance between two motors, stop the Inverter output before operating the
MC.
Installing a Thermal Overload Relay Contact
This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however,
more than one motor is operated with one Inverter or a multi-polar motor is used, always install a thermal
relay (THR) between the Inverter and the motor and set L1-01 to 0 (no motor protection). The control circuit
should be designed so that the contacts of the thermal overload relay turn OFF the magnetic contactor on the
main circuit inputs.
2-16
Wiring Main Circuit Terminals
Cable Length between Inverter and Motor
If the cable between the Inverter and the motor is long, the high-frequency leakage current will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust
the carrier frequency (set in C6-01, C6-02) as shown in Table 2.7. (For details, refer to Chapter 5 User Constants.)
Table 2.7 Cable Length between Inverter and Motor
Cable length
50 m max.
100 m max.
More than 100 m
Carrier frequency
15 kHz max.
10 kHz max.
5 kHz max.
Ground Wiring
Observe the following precautions when wiring the ground line.
• Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that
of the 400 V Inverter with a ground resistance of less than 10 Ω.
• Do not share the ground wire with other devices, such as welding machines or power tools.
• Always use a ground wire that complies with technical standards on electrical equipment and minimize the
length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the
ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
• When using more than one Inverter, be careful not to loop the ground wire.

Connecting a Braking Resistor (ERF)
A Braking Resistor mounted to the Inverter can be used with 200 V and 400 V Class Inverters with outputs
from 0.4 to 11 kW.

The braking resistor connection terminals are B1 and B2. Do not connect the resistor to any other terminals. Otherwise the resistor and other equipment may get damaged
IMPORTANT
Connecting a Braking Resistor Unit (LKEB) and Braking Unit (CDBR)
Connect a Braking Resistor Unit and Braking Unit to the Inverter as shown in the Fig 2.8.
Table 2.9

0 (Disable overheat protection)
L3-04 (Stall prevention selection during deceleration)

0 (Disable stall prevention function)
3 (Enable stall prevention function with braking resistor)
The Braking Resistor Unit will not work if L3-04 is set to 1 (i.e., if stall prevention is enabled for deceleration). Hence the deceleration time may be longer than the set time (C1-02/04/06/08).
2-18
Wiring Main Circuit Terminals
To prevent the braking unit/braking resistor unit from overheating, design the control circuit to turn OFF the
power supply using the thermal overload relay contacts of the Unit as shown in Fig 2.8.

Wire Sizes
For remote operation using analog signals, keep the control line length between the Analog Operator or operation signals and the Inverter to 50 m or less, and separate the lines from main power lines or other control circuits to reduce induction from peripheral devices.
When setting frequencies from an external frequency setter (and not from a Digital Operator), used shielded
twisted-pair wires and ground the shield so as the contact area of the shield and ground becomes maximal.
See the figure below for details on the wiring.

Wiring Control Circuit Terminals
Control Circuit Wiring Precautions
Observe the following precautions when wiring control circuits.
• Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2,
W/T3,
,
1,
2, and
3) and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC, M1, M2, M3, M4, M5, and M6 (contact out-
puts) from wiring to other control circuit terminals.
• If using an optional external power supply, it shall be a UL Listed Class 2 power supply source.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults.
• Ground the cable shields so as to maximise the contact area of the shield and ground.
• Cable shields have to be grounded on both cable ends.
2-27
Wiring Check
Checks
Check all wiring after wiring has been completed. Do not perform continuity check on control circuits. Perform the following checks on the wiring.
• Is all wiring correct?
• Have no wire clippings, screws, or other foreign material been left?
• Are all screws tight?
• Are any wire ends contacting other terminals?

Wiring Method and Precautions
The wiring method is the same as the one used for straight solderless terminals. Refer to page 2-22. Observe
the following precautions when wiring.
• Separate the control signal lines for the PG Speed Control Card from main power lines and other control
circuits.
• Connect the shield when connecting to a PG. The shield must be connected to prevent operational errors
caused by noise. Also, do not use any lines that are more than 100 m long.
• Connect the shield (green grounding cable of the option card) to the shield terminal (E).
• Do not solder the ends of wires. Doing so may cause contact faults.
• When not using straight solderless terminals, strip the wires to a length of approximately 5.5 mm.

Selecting the Number of PG (Encoder) Pulses
The setting for the number of PG pulses depends on the model of PG Speed Control Card being used. Set the
correct number for your model.
PG-A2/PG-B2
The maximum response frequency is 32,767 Hz.
Use a PG that outputs a maximum frequency of approximately 20 kHz for the nominal speed of the motor.
Motor speed at maximum output frequency (min–1)

Autotuning Mode
Autotuning automatically measures and sets the required motor constants for the best performance in all control modes. Always perform autotuning before starting operation when using vector control.
When V/f control has been selected, only stationary autotuning for line-to-line resistance can be selected.
When the motor cannot be disconnected from the load, and vector control shall be used perform stationary
autotuning.
Example of Operation
Set the motor rated output power (in kW), rated voltage, rated current, rated frequency, rated speed, and number of poles specified on the nameplate of the motor and then press the RUN key. The motor is automatically
run and the measured motor constants are set.
Always set the above items. Otherwise autotuning cannot be started otherwise, e.g. it cannot be started from

Trial Operation
Autotuning
Use the following procedure to perform autotuning to automatically set motor constants when using the openloop vector control method, when the cable length is long, etc.
Setting the Autotuning Mode
One of the following three autotuning modes can be set.
• Rotating autotuning
• Non-rotating autotuning
• Non-rotating autotuning for line-to-line resistance only
Rotating Autotuning (T1-01 = 0)
Rotating autotuning is used for open-vector control only. Set T1-01 to 0, input the data from the nameplate,
and then press the RUN key on the Digital Operator. The Inverter will stop the motor for approximately
1 minute and then set the required motor constants automatically while operating the motor for approximately
1 minute
1. Always disconnect the motor from the machine and confirm that it is safe to operate the motor before
performing rotational autotuning.
2. If the motor and load cannot be disconnected perform non-rotating autotuning, but always use rotating
autotuning whenever it is possible to operate the motor to increase performance.
IMPORTANT
Non-rotating Autotuning (T1-01 = 1)
Non-rotating autotuning is used for open-vector control only. Set T1-01 to 1, input the data from the nameplate, and then press the RUN key on the Digital Operator. The inverter will supply power to the non-rotating
motor for approximately 1 minute and some of the motor constants will be set automatically. The remaining
motor constants will be set automatically during the first time operation.
IMPORTANT
1. Power will be supplied to the motor when non-rotating autotuning is performed but the motor will not turn.
Do not touch the motor until autotuning has been completed.
2. When performing non-rotating autotuning connected to a conveyor or other machine, ensure that the
holding brake is not activated during autotuning.
3. Try to keep the motor load ratio to 50% or less when the system is operated the first time after performing non-rotating autotuning.
Non-rotating Autotuning for Line-to-Line Resistance (T1-01 = 2)
Non-rotating autotuning for line-to-line resistance can be used in any control method. This is the only possible
autotuning for V/f control and V/f control with PG.
Autotuning can be used to prevent control errors when the motor cable is long, the cable length has changed or
when the motor and inverter have different capacities.
To perform autotuning in V/f control or V/f control with PG, set T1-02 (Motor rated power) and T1-04 (Motor
rated current) and then press the RUN key on the Digital Operator. The Inverter will supply power to the nonrotating motor for approximately 20 seconds and the Motor line-to-line resistance (E2-05) and cable resistance
will be automatically measured
1. Power will be supplied to the motor when stationary autotuning for line-to-line resistance is performed
but the motor will not turn. Do not touch the motor until autotuning has been completed.
2. When performing non-rotating autotuning connected to a conveyor or other machine, ensure that the
holding brake is not activated during autotuning.

Only setting 2 (non-rotating autotuning for line-to-line resistance only) is possible for V/f control or V/f control with PG.
Stable vector control will be possible when the setting is between 50% and 100%.
For an inverter motor or vector control motor, the voltage and frequency may be lower than for a general-purpose motor. Always confirm setting on the
nameplate or in test reports. Also, if you know the no-load values, set the no-load voltage in T1-03 and the no-load frequency in T1-05 to obtain better
accuracy.

Trial Operation
Digital Operator Displays during Autotuning
The following displays will appear on the Digital Operator during autotuning.
Table 4.3 Digital Operator Displays during Autotuning
Digital Operator Display
Description
Autotuning mode selection: T1-01
Using the same procedures as for the programming
modes check and set the T1 constants according to
information on the previous page.
Be sure that T1-01 (Autotuning Mode Selection) is set
correctly and check safety around the motor and
machine.
Motor base speed: T1-07
(For rotational autotuning)
The autotuning start display will appear when all settings through T1-07 have been completed. The
A.TUNE and DRIVE indicators will light.
Autotuning started: TUn10
Autotuning will start when the RUN key is pressed
from the autotuning start display.
The left digit in TUn is the Motor 1/2 Selection
(T1-00) and the right digit is the Autotuning Mode
Selection (T1-01).
Autotuning
Stop command input
If the STOP key is pressed or a measurement error
occurs during autotuning, and error message will be
display and autotuning will be stopped.
Refer to Errors during Autotuning on page 7-13.
Autotuning completed
END will be displayed after approximately 1 minute,
indicating that autotuning has been completed.

Application Settings
User constants can be set as required in advanced programming mode (i.e. the ADV indicator lights on the
Digital Operator). All the constants that can be set in quick programming mode can also be displayed and set
in advanced programming mode.
Setting Examples
The following are examples of settings for applications.
• When using an Inverter-mounted braking resistor (ERF), set L8-01 to 1 to enable ERF braking resistor
overheating protection.
• To prevent the machine from being operated in reverse, set b1-04 to 1 to disable reverse operation.
• To increase the speed of a 50 Hz motor by 10%, set E1-04 to 55.0 Hz.
• To use a 0 to 10 V analog signal for a 50 Hz motor for variable-speed operation between 0 and 45 Hz (0%
to 90% speed deduction), set H3-02 to 90.0%.
• To limit the speed range between 20% and 80% set d2-01 to 80.0% and set d2-02 to 20.0%.
No-load Operation
This section describes trial operation in which the motor is in no-load state, that means the machine is not connected to the motor. To avoid failures caused due to the wiring of the control circuit it’s recommended to use
the LOCAL mode. Press the LOCAL/REMOTE key on the Digital Operator to change to LOCAL mode (the
SEQ and REF indicators on the Digital Operator should be OFF).
Always confirm safety around the motor and machine before starting Inverter operation from the Digital
Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter. For applications, at which the machine can be driven in one direction only, check the motor rotation direction.
Operation with Jog frequency reference (d1-17, default: 6.00 Hz) can be started and stopped by pressing and
releasing the JOG key on the Digital Operator. If the external control circuit prevents operation from the Digital Operator, confirm that emergency stop circuits and machine safety mechanisms are functioning, and then
start operation in REMOTE mode (i.e., with a signal from the control signal terminal). The safety precautions
must always be taken before starting the inverter and the motor connected.
Both, a RUN command (forward or reverse) and a frequency reference (or multi-step speed command) must
be provided to start Inverter operation.
Loaded Operation
Connecting the Load
• After confirming that the motor has stopped completely, connect the mechanical system.
• Be sure to tighten all the screws when connecting the motor shaft to the mechanical system.
4-12
Trial Operation
Operation using the Digital Operator
• Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation.
• If fault occurs during operation, make sure that the STOP key on the Digital Operator is easily accessible.
• At first, set the frequency reference to a low speed, e.g. to one tenth of the normal operating speed.
Checking Operating Status
• Having checked that the operating direction is correct and that the machine is operating smoothly at slow
speed, increase the frequency reference.
• After changing the frequency reference or the rotation direction, check that there is no oscillation or abnor-
mal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too
high.
• Refer to Adjustment Suggestions on page 4-14 if hunting, vibration, or other problems originated by the
control system occur.
Check and Recording User Constants
Use verify mode (i.e., when the VERIFY indicator on the Digital Operator lights up) to check user constants
that have been changed for trial operation and record them in a user constant table.
Any user constants that have been changed by autotuning will also be displayed in verify mode.
If required, the copy function in constants o3-01 and o3-02 displayed in advanced programming mode can be
used to copy the changed settings from the inverter to a recording area in the Digital Operator. If changed settings are saved in the Digital Operator, they can be easily copied back to the Inverter to speed up system
recovery if for any reason the inverter has to be replaced.
The following functions can also be used to manage user constants.
• Recording user constants
• Setting access levels for user constants
• Setting a password
Recording User Constants (o2-03)
If o2-03 is set to 1 after completing trial operation, the settings of user constants will be saved in a separate
memory area in the inverter. When the Inverter settings have been changed for any reason, the user constants
can be initialized to the settings saved in the separate memory area by setting A1-03 (Initialize) to 1110.
User Constant Access Levels (A1-01)
A1-01 can be set to 0 (monitoring-only) to prevent user constants from being changed. A1-01 can also be set
to 1 (User-specified Constants) to display only constants required by the machine or application in a programming mode. These constants can be determined by setting the A2-XX constants.
Password (A1-04 and A1-05)
When the access level is set to monitoring-only (A1-01 = 0), a password can be set so that user constants will
be displayed only when the correct password has been input.

Adjustment Suggestions
If hunting, vibration, or other problems originated by the control system occur during trial operation,
adjust the constants listed in the following table according to the control method. This table lists only the

then adjust the Slip Compensation Gain (C3-01) to between 0.5 and 1.5. The default setting for V/f control
is C3-01 = 0.0 (slip compensation disabled).
• To improve speed response and stability in V/f control with a PG (A1-02 = 1), set the ASR constants (C5-
01 to C5-05) to between 0.5 and 1.5 times the default. (Normally it is not necessary to adjust this setting.)
The following user constants will also affect the control system indirectly.
Table 4.5 Constants Affecting Control and Applications Indirectly
Name (Constant Number)
Application
Heavy/Normal Duty selection (C6-01)
Sets the maximum torque and overload capability to 120% or 150%.
DWELL function (b6-01 to b6-04)
Used for heavy loads or large machine backlashes.
Acceleration/deceleration times
(C1-01 to C1-11)
Adjust torque during acceleration and deceleration.
S-curve characteristics (C2-01 to C2-04)
Used to prevent shock when completing acceleration.
Jump frequencies (d3-01 to d3-04)
Used to avoid resonance points during acceleration or deceleration.
Analog input filter time constant (H3-12)
Used to prevent fluctuations in analog input signals caused by noise.
Stall prevention (L3-01 to L3-06)
Used to prevent OV (overvoltage errors) and motor stalling for heavy
loads or rapid acceleration/deceleration. Stall prevention is enabled by
default and the setting normally has not to be changed. When using a
braking resistor, however, disable stall prevention during deceleration by
setting L3-04 to 0 or set it to 3 (enabled with braking resistor).
Torque limits (L7-01 to L7-04)
Set the maximum torque during vector control. If a setting is reduced,
stalling can occur under heavy loads.

Set T1-02 and T1-04 when 2 is set for T1-01. For V/f control or V/f control with PG a set value 2 is possible only.
The factory setting depends on the Inverter capacity. (The value for a 200 V Class Inverter for 0.4 kW is given.)
These are values for a 200 V class Inverter. Values for a 400 V class Inverter are double.
The setting range is from 10% to 200% of the Inverter rated output current. (The value for a 200 V Class Inverter for 0.4 kW is given.)
The upper setting limit will be 150.0 Hz when C6-01 is set to 0.

Application and Overload Selections
Select the Overload to Suit the Application
Set C6-01 (Heavy Duty: Low carrier, constant torque, Normal Duty: High carrier, variable torque) depending
on the application for which the Inverter is used. The setting ranges for the Inverter carrier frequency, overload
tolerance, and maximum output frequency depend on the setting of C6-01. For applications like fans and
blowers (quadratic torque characteristic) set C6-01 to 1 (Normal Duty). For applications with a constant
torque characteristic set C6-01 to 0 (Heavy Duty).

Difference Between Heavy Duty and Normal Duty
The characteristics of Heavy Duty (low carrier, constant torque) and Normal Duty (high carrier, variable
torque) are shown below.
Heavy Duty: Low Carrier, Constant Torque
Normal Duty: High Carrier, Variable Torque
Variable Torque
Constant Torque
Torque
Torque
Motor speed
Motor speed
Constant torque means a constant load torque for all
motor speed. Typical applications are pushers, conveyors, cranes, and other high friction or heavy loads. These
applications may require overload capability.
Variable torque means that the load torque will decrease
as the speed decreases. Typical applications are fans and
pumps. Normally not much overload capability is
required.
Low carrier: High audible noise is present.
High carrier: Almost no audible noise.
Setting Precautions
C6-01 (Heavy/Normal Duty Selection)
When setting C6-01, observe the following precautions.
• Depending on the set value in C6-01, the setting range of the related constants is limited as follows:

Carrier Frequency
When selecting the carrier frequency, observe the following precautions:
• When using a device with C6-01 set to 1 (Normal Duty), adjust the carrier frequency according to the
cases shown below.
If the wiring distance between Inverter and motor is long: Set the carrier frequency low. (Use the following
values as guidelines.

0 to 6 (15 kHz)
0 to 4 (10 kHz)

If speed and torque vary at low speeds: Set the carrier frequency low.
If Inverter noise is affecting peripheral devices: Set the carrier frequency low.
If leakage current from the Inverter is large: Set the carrier frequency low.
If metallic noise from the motor is large: Set the carrier frequency high.
• When using V/f control or V/f control with PG, you can vary the carrier frequency to match the output fre-
quency, as shown in the following diagram, by setting C6-03 (Carrier Frequency Upper Limit), C6-04
(Carrier Frequency Lower Limit), and C6-05 (Carrier Frequency Proportional Gain).

• With vector control, the carrier frequency is fixed by the Carrier Frequency Upper Limit in C6-03 if
user-set, or by the carrier frequency set in C6-02.
• To fix the carrier frequency, set C6-03 and C6-04 to the same value, or set C6-05 to 0.

Deceleration to Stop
If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 0, the motor decelerates to stop according to the deceleration time that has been set. (Factory setting: C1-02 (Deceleration Time
1))
If the output frequency when decelerating to stop falls below b2-01, the DC injection brake will be applied
using the DC current set in b2-02 for the time set in b2-04.
For deceleration time settings, refer to page 6-19 Setting Acceleration and Deceleration Times.

Using the DC Injection Brake
Set constant b2-03 to apply DC injection to the motor, before it starts to accelerate. Applying DC injection at
start will stop the motor before starting if it was coasting through inertia or wind mill effect.
Set b2-03 to 0 to disable the DC injection brake at start.
Set constant b2-04 to apply a DC injection brake to the motor at stopping. It prevents the motor from coasting
when it would not be stopped completely using the normal deceleration. This can occur if the inertia is very
high. The DC injection brake can be disabled by setting b2-04 to 0.
Set the DC injection brake current using b2-02.

Setting Acceleration and Deceleration Times
Acceleration time indicates the time to increase the output frequency from 0% to 100% of the maximum output frequency (E1-04). Deceleration time indicates the time to decrease the output frequency from 100% to
0% of (E1-04). The accel./decel. times 1 are used with the factory setting, the accel./decel. times 2 to 4 can be
selected using a multifunction input.

Commands
Four different acceleration times and deceleration times can be set. When the multi-function input terminals
(H1-) are set to 7 (acceleration/deceleration time selection 1) and 1A (acceleration/deceleration time
selection 2), you can switch the acceleration/deceleration time even during operation by combining the
ON/OFF status of the terminals.

Switching Acceleration and Deceleration Time Automatically
Use this setting when you want to switch acceleration/deceleration time automatically using the output frequency.
When the output frequency reaches the set value in C1-11, the Inverter switches the acceleration/deceleration
time automatically as shown in the following diagram.
Set C1-11 to a value other than 0.0 Hz. If C1-11 is set to 0.0 Hz, the function will be disabled.

When output frequency ≥ C1-11, acceleration and deceleration are performed using

When output frequency &lt; C1-11, acceleration and deceleration are performed using
Acceleration/deceleration Time 4 (C1-07, C1-08).

Adjusting Acceleration and Deceleration Time Using an Analog Input
If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) to 5 (acceleration/deceleration time gain), you can adjust the acceleration/deceleration time using terminal A2's input voltage.
The resulting acceleration time is as follows:
Acceleration time = C1-01 set value x acceleration/deceleration time gain
Acceleration/deceleration time gain
(Acceleration/deceleration gain from 1 to
10 V) = 10 V/Input voltage (V) x 10 (%)
Fig 6.19 Acceleration/Deceleration Time Gain Using an Analog Input
Entering S-curve Characteristics in the Acceleration and Deceleration Time
By performing acceleration and deceleration using an S-curve pattern, you can reduce shock when starting and
stopping the machine.
Four different S-curve characteristic times can be set: At acceleration start, at deceleration start, at acceleration
end and at deceleration end.
When S-curve is set, calculate acceleration/deceleration time as follows:

Accelerating and Decelerating Heavy Loads (Dwell Function)
The dwell function temporarily holds the output frequency when starting or stopping heavy loads. By using
this function the motor can be prevented from stalling. When using the dwell function, deceleration to stop

Preventing the Motor from Stalling During Acceleration (Stall Prevention
During Acceleration Function)
The Stall Prevention During Acceleration function prevents the motor from stalling if a heavy load is applied
to the motor, or sudden rapid acceleration is performed.
If you set L3-01 to 1 (enabled) and the Inverter output current reaches 85 % of the set value in L3-02, the
acceleration rate will begin to slow down. When L3-02 is exceeded, the acceleration will stop.
If you set L3-01 to 2 (optimum adjustment), the motor accelerates so that the current is held at the level set in
L3-03. With this setting, the acceleration time setting is ignored.

Setting Precautions
• If the motor capacity is small compared to the Inverter capacity or if the inverter is operated using the fac-
tory settings and the motor stalls, lower the set value of L3-02.
• If using the motor in the constant output range, L3-02 will be automatically lowered to prevent stalling.
L3-03 is the limit value to prevent the stall prevention level in the constant output range from being
reduced more than necessary.
• Set the constants as a percentage taking the inverter rated current to be 100%.

Setting the Stall Prevention Selection During Deceleration (L3-04)
There are four different settings selectable for L3-04.
L3-04=0: This setting disables the stall prevention function during deceleration. The motor will be decelerated using the time set in C1-02 (C1-04/06/08). If the load inertia is very high and an OV fault
occurs during deceleration a Braking option has to be used or the time has to be lengthened.
L3-04=1: This setting enables the stall prevention during deceleration. The inverter tries to decelerate within
the set deceleration time. It also observes the DC bus voltage. If the DC bus voltage reaches the
stall prevention level the deceleration is stopped and the output frequency is held. When the DC
bus voltage falls below the stall prevention level the deceleration will be continued.
L3-04=2: This setting enables the stall prevention during deceleration. The deceleration time set as C1-
is taken as reference. The function automatically tries to optimize the deceleration time by observing the DC bus voltage and shortening the deceleration time. The function does not lengthen the
deceleration time, i.e. if C1- is set too short OV may occure.
L3-04=3: This setting enables the stall prevention during deceleration using a braking option. It works similar to setting 2, the only difference is that a braking option is used. The deceleration time set in
C1- is also disregarded.

• When using the braking option (braking resistor, braking resistor units, and braking units), be sure to set
constant L3-04 to 0 or 3.
• When a braking option is used and the deceleration time shall be optimized (shorter than setting of
C1-02/04/06/08), L3-04 has to be set to 3.

Adjusting Analog Frequency Reference Using Constants
The frequency reference can be input from the control circuit terminals using analog voltage and current signals.
If using terminal A1 as an input terminal for the frequency reference value, perform adjustments using constants H3-01 to H3-03. If using multi-function analog input terminal A2 as a frequency reference terminal,
perform adjustments using H3-08 to H3-11. Set the analog input signal level using the constants H3-01 or
H3-08. Refer the following figures for setting the input gain and bias.

The frequency gain for terminal A1 is the sum of H3-02 and terminal A2 gain. For example, when H3-02 is set
to 100% and terminal A2 is set to 5 V, the terminal A1 frequency reference will be 50%.

This section explains functions for improving motor operating efficiency.
Reducing Motor Speed Fluctuation (Slip Compensation Function)
When the load is large, the motor slip also grows and the motor speed decreases. The slip compensation function keeps the motor speed constant, regardless of changes in load. When the motor is operating at the rated
load, constant E2-02 (Motor Rated Slip) &times; the slip compensation gain value in constant C3-01 is added to the
output frequency.

Adjusting Slip Compensation Gain (C3-01)
The setting value of C3-01 depends on the control method. The factory settings are:
• V/f control without PG: 0.0
• Open loop vector control: 1.0
Set C3-01 to 1.0 to compensate the slip depending on the actual torque output status using the rated slip
(E2-02/E4-02) as reference.
Adjust the slip compensation gain using the following procedure.
1. Set E2-02 (Motor Rated Slip) and E2-03 (Motor No-load Current) correctly.
The motor rated slip can be calculated using the values on the motor nameplate and the following formula.
Motor rated slip (Hz) = Motor rated frequency (Hz) - Rated Motor speed (rpm) &times; No. of motor poles / 120
The motor rated slip is set automatically in vector control using the autotuning function.
2. In V/f control, set C3-01 to 1.0. Setting this constant to 0.0 disables the slip compensation.
3. Apply a load, and measure the speed to adjust the slip compensation gain. Adjust the slip compensation
gain by 0.1 at a time. If the speed is less than the target value, increase the slip compensation gain, and if
the speed is higher than the target value, reduce the slip compensation gain.
Adjusting Slip Compensation Primary Delay Time Constant (C3-02)
The slip compensation delay time constant is set in ms.
The setting value of C3-02 depends on the control method. The factory settings are:
• V/f control without PG: 2000 ms
• Open loop vector control: 200 ms
Normally, there is no need to change these settings. When the slip compensation response is low, lower the set
value. When the speed is unstable, increase the set value.
Adjusting Slip Compensation Limit (C3-03)
Using constant C3-03 the upper limit for the slip compensation can be set as a percentage, taking the motor
rated slip as 100%.
If the speed is lower than the target value but does not change even after adjusting the slip compensation gain,
the slip compensation limit may have reached. Increase the limit, and check the speed again. Always make
sure that the value of the slip compensation limit and reference frequency does not exceed the tolerance of the
machine.
The following diagram shows the slip compensation limit for the constant torque range and fixed output range.

Improved Operating Efficiency
Selecting Slip Compensation Function During Regeneration (C3-04)
Set whether to enable or disable the slip compensation function during regeneration.
If the slip compensation function operates during regeneration, you might have to use a braking option (braking resistor, braking resistor unit, and braking unit).
Operation Selection when Output Voltage Saturated (C3-05)
The Inverter cannot output a voltage that is higher than the input voltage. If the output voltage command to the
motor (monitor constant U1-06) exceeds the input voltage in the high-speed region, the output voltage
becomes saturated, and inverter cannot respond to speed or load changes. This function automatically reduces
the output voltage to avoid voltage saturation.
Torque Compensation for Sufficient Torque at Start and Low-speed
Operation
The torque compensation function detects a rising motor load, and increases the output torque.
In V/f control the inverter calculates the motor primary loss voltage and adjusts the output voltage (V) to compensate insufficient torque at startup and during low-speed operation. The compensation voltage is calculated
as follows: Motor primary voltage loss &times; constant C4-01.
The vector control separates the motor excitation current and the torque producing current and controlles each
of the two separately.
The torque producing current is calculated as follows: Calculated torque reference &times; C4-01

• If the cable is very long, increase the set value.
• If the motor capacity is smaller than the Inverter capacity (max. applicable motor capacity), increase the

Adjusting the Torque Compensation Primary Delay Time Constant (C4-02)
Set the torque compensation function primary delay in ms.

• V/f control with PG: 200 ms
• open loop vector control: 20 ms
Normally, there is no need to change this setting. Adjust the constant under the following circumstances:
• If the motor is vibrating, increase the set value.
• If the motor response is low, decrease the set value.
Starting Torque Compensation Function (C4-03 to C4-05)
Starting torque compensation can be input to speed up the torque command at starting with open-loop vector
control.
This function is effective for machinery with large friction loads, cranes, and other applications where high
starting torque is required. It works like shown in the following diagram.

• The compensation works only for the motoring side. It can not be used with a regenerative load.
• If a large shock is generated at starting increase the starting torque compensation time constant (C4-05).

Motor speed [Hz]
(Max. output frequency)
Fig. 6.34 ASR Gain and Integral Time Depending on the Output Frequency
Use the following procedure to adjust the ASR gain and integral time. The mechanical system and the load
should be connected while this procedure.
Gain and Integral Time at Minimum Output Frequency (C5-03 and C5-04)
1.
Operate the motor at the minimum output frequency.
2.
Increase C5-03 (ASR proportional gain 2) to a level where there is no oscillation in motor speed.
3.
Decrease C5-04 (ASR integral time 2) to a level where there is no oscillation in motor speed.
4.
Monitor the inverter’s output current and verify that it is less than 50% of the inverter rated current. If the
output current exceeds 50% of the inverter’s rated current, decrease C5-03 and increase C5-04.
Gain and Integral Time at Maximum Output Frequency (C5-01 and C5-02)
1.
Operate the motor at the maximum output frequency.
2.
Increase C5-01 (ASR proportional gain 1) to a level where there is no oscillation in motor speed.
3.
Decrease C5-02 (ASR integral time 1) to a level where there is no oscillation in motor speed.
Gain and Integral Time Adjustments for Integral Control during
Acceleration/Deceleration (F1-07)
Normally the integral control is disabled during Acceleration/Deceleration (F1-07=0). Enable this function if
you want the motor speed to follow the frequency reference very closely during accel./decel. The integral
operation causes the speed to reach the target value as fast as possible. Wrong setting may cause oscillations
or low speed response.
1.
Set F1-07 to “1” to enable integral operation at all times.
2.
Make the constant settings shown below in order to observe the speed waveform while making fine
adjustments to the gain.

The multi-function analog outputs have the following functions with these constant settings.
•
Multi-function analog output 1 (terminal FM): Outputs Inverter’s output frequency 0 to &plusmn;10 V).
•
Multi-function analog output 2 (terminal AM): Outputs the actual motor speed (0 to &plusmn; 10 V).

We recommend monitoring both, the output frequency and the motor speed to monitor the response delay
or deviations from the reference value, as shown in the following diagram.

Fig. 6.36 Gain Adjustments
4.
If the overshooting or undershooting can’t be eliminated by adjusting the gain and integral time values,
decrease the ASR limit (C5-05) to lower the frequency reference compensation limit.
Note the following:
•
Since C5-05 can’t be changed during operation, stop the Inverter’s operation and then decrease the
ASR limit by 0.5 (%).
•
Perform step 3 again after the setting has been changed.
•
The ASR limit is the frequency limit for compensation by speed control. This frequency limit is set
as a percentage of the maximum output frequency.
•
If the frequency limit is lowered too much, the motor speed might not reach the target speed. Verify
that the target speed is reached during normal operation.

Multi-function Input Settings (H1-01 to H1-05) (Terminal S3 to S7)

thereby to disable the ASR.
•
The ASR is disabled when the multifunction input is ON.
Speed Control Integral Disable: “E”
•
When one of the digital inputs is set to “E” this input can be used to switch the speed control between PI
and P control.
•
P control is active when the input is ON (Integral value is reset).
Hunting-Prevention Function
The hunting-prevention function suppresses hunting when the motor is operating with a light load. This function can be used in the V/f control modes only.

Setting Precautions
• When the output torque reaches the torque limit, control and compensation of the motor speed is disabled
to prevent the output torque from exceeding the torque limit. The torque limit has the priority.
• When using the torque limit for hoist applications, do not carelessly lower the torque limit value, as this
may result in motor stalling.
• When using an analog input for torque limit setting, an analog input value of 10 V/20 mA is equal to a
torque limit of 100% of the motor rated torque. To raise the torque limit value at an analog input of 10
V/20 mA for instance to 150% of the rated torque, set the input terminal gain to 150.0 (%). Adjust the gain
for multi-function analog input terminal A2 using H3-10.
• The torque limit accuracy is &plusmn;5% at the output frequency of 10 Hz or above. When output frequency is
lower than 10 Hz, the accuracy is lowered.
Preventing Motor Stalling During Operation
Stall prevention during operation prevents the motor from stalling by automatically lowering the Inverter's
output frequency when a transient overload occurs while the motor is operating at a constant speed.
Stall prevention during operation is enabled only in V/f control. If the Inverter output current continues to
exceed the setting in constant L3-06 for 100 ms or longer, the motor speed is reduced. Set whether to enable or
disable the stall prevention using constant L3-05. Set the according deceleration times using C1-02 (Deceleration time 1) or C1-04 (Deceleration Time 2).
If the Inverter output current reaches the set value in L3-06 – 2%, the motor will accelerate again to the set frequency.

Changing Stall Prevention Level during Operation Using an Analog Input
If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) to 8 (stall prevention during
operation level), you can change the stall level during operation using the analog input A2.
If the analog input A2 is used to set the stall prevention level, the function uses either the value from the
multi-function analog input terminal A2 input level or the set value in constant L3-06. The lower value of
both will be used as stall prevention level.
Stall prevention level during operation

terminal A2 input level
Fig 6.40 Stall Prevention Level during Operation Using an Analog Input
If the motor capacity is smaller than the Inverter capacity or the motor stalls when operating at the factory settings, lower the stall prevention level during operation.
Detecting Motor Torque
If an excessive load is applied to the machinery (overtorque) or the load suddenly drops (undertorque), you
can output an alarm signal to one of the multi-function output terminal M1-M2, M3-M4, or M5-M6.
To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection
NO/NC) in one of the constant H2-01 to H2-03 (multi-function output terminals M1-M2, M3-M4, and
M5-M6 function selection).
The overtorque/undertorque detection level is the current level (taking the inverter rated output current as
100%) in V/f control, and the motor torque (taking the motor rated torque as 100%) in vector control.

Setting Motor Overload Protection Characteristics (L1-01)
Set the overload protection function in L1-01 according to the applicable motor.
The induction motor's cooling abilities differ according to the motor type. Consequently, you must select the
electronic thermal protection characteristics.
Set L1-01 to:
0: to disable the thermal motor protection function.
1: to enable the thermal motor protection for a fan cooled general purpose motor (self-cooled).
2: to enable the thermal motor protection for an inverter motor (externally cooled).
3: to enable the thermal motor protection for a special vector motor (exernally cooled).
Setting Motor Protection Operation Time (L1-02)
Set the motor protection operation time in L1-02.
The motor protection operation time is the time for that the motor can handle a 150% overload when it was
running with the rated load before (i.e. operating temperature was reached before applying the 150% overload). This time should be set is constant L1-02. The factory setting is 60 sec.
The following diagram shows an example of the characteristics of the electronic thermal protection operation
time (L1-02 = 1.0 min., operation at 50 Hz, general-purpose motor characteristics, when L1-01 is set to 1)

Fig 6.42 Motor Protection Operation Time
Setting Precautions
• If multiple motors are connected to one inverter, set constant L1-01 to 0 (disabled). To protect each of the
motors, use a control circuit that switches off the inverter output when one of the motors overheats.
• With applications where the power supply is often turned ON and OFF, there is a risk that the motor cannot
be protected even if this constant has been set to 1 (enabled), because the thermal value will be reset after
inverter power supply switch off.
• For save overload tripping, set the value in constant L1-02 to a low setting.
• When using a general-purpose motor (standard motor), the cooling ability will be lowered by f1/4 (fre-
quency). Consequently, a low output frequency may cause motor overload protection (OL1) to occur, even
when the output current is far below the rated current. If operating using the rated current at a low frequency, use a special motor externally cooled.
Setting the Motor Overload Pre-Alarm
If the motor overload protection function is enabled (i.e., L1-01 is set to other than 0) and you set H2-01 to
H2-03 (multi-function output terminals M1-M2, M3-M4, and M5-M6 function selection) to 1F (motor overload OL1 pre-alarm), the motor overload pre-alarm will be enabled. If the electronic thermal value reaches
minimum 90% of the overload detection level, the output terminal that has been set will be turned ON.

•
Because this function uses a voltage signal to terminal A2, pin 2 of the DIP-switch S1 on the control terminal board has to be turned to OFF for A2 voltage input. The factory setting is ON (A2 current input).
•
For the same reason the parameter H3-08 (analog input terminal A2 signal level) has to be set to 0 (0-10V
input).
Machine Protection
Limiting Motor Rotation Direction and Output Phase Rotation
If the motor reverse rotation is prohibited, a reverse run command will not be accepted, even if it is input. Use
this setting for applications in which reverse motor rotation can cause problems (e.g., fans, pumps, etc.)
In V/F mode it is also possible to change the output phase order by changing a parameter. This much easier
and faster than changing the wiring if the motor rotational direction is wrong. If this function is used a prohibition of reverse direction is not possible.

Automatically Restart
This section explains functions for continuing or automatically restarting Inverter operation after a
momentary power loss.
Restarting Automatically After Momentary Power Loss
After a momentary power loss, the Inverter can be restarted automatically to continue motor operation.
To restart the Inverter after power is recovered, set L2-01 to 1 or 2.
If L2-01 is set to 1, the inverter will restart, when power is recovered within the time set in L2-02. If the power
loss time exceeds the time set in L2-02, an UV1 alarm (DC bus undervoltage) will be detected.
If L2-01 is set to 2, the inverter will restart, when the main power supply is recovered as long as the control
power supply (i.e., power supply to the control circuit) is maintained. Consequently, alarm UV1 (DC bus undervoltage) will not be detected.

• Error output signals are not output during momentary power loss recovery.
• To continue Inverter operation after power has been restored, make settings so that RUN commands from
the control main circuit terminal are stored even while power is suspended.
• If the momentary power loss operation selection is set to 0 (Disabled), an alarm UV1 (main circuit under-
voltage) will be detected when the momentary power loss exceeds 15 ms during operation.

mand and external search command are both ON. These two commands must be kept on, at least for the
time set in parameter L2-03.
• If the Inverter output is equipped with a contactor, set the contactor operation delay time in the Speed
Search Wait Time (b3-05). The factory setting is 0.2 s. When not using a contactor, you can reduce the
search time to 0.0 s. After waiting for the speed search wait time, the Inverter starts the speed search.
• Constant b3-02 (current detection level for search completion) is effective only when current detection
speed search is selected. When the current falls below the detection level, the speed search is supposed to
be as completed, and the motor accelerates or decelerates to the set frequency.
• If an overcurrent (OC) is detected when using speed search after power recovery, lengthen the Minimum
Baseblock Time (L2-03).
Application Precautions for Speed Searches Using Estimated Speed
• When using V/f control with or without a PG, always perform stationary autotuning for line-to-line resis-
tance before using speed searches based on calculated speeds.
• When using open loop vector control, always perform rotational autotuning before using speed searches
based on calculated speeds.
• If the cable length between the motor and Inverter is changed after autotuning has been performed, per-
form stationary autotuning for line-to-line resistance again.

Automatically Restart
Speed Search Selection
The speed search method can be selected using b3-01. If b3-01 is set to 0 the search method is speed calculation. It has to be activated by a multi-function input (H1- set to 61 or 62).
If b3-01 is set to 1, the search method is speed calculation too, but speed search is performed at every RUN
command and has not to be activated by a multifunction input.
The same is valid for setting b3-01 to 2 or 3, only the search method is current detection and not speed calculation.

Continuing Operation at Constant Speed When Frequency Reference Is
Lost
The frequency reference loss detection function can be used to continue operation at reduced speed using the
set value in parameter L4-06 as frequency reference value. When using an analog input as frequency reference
source, a frequency reference loss is detected, when the reference value drops over 90 % in 400 ms or less.
When an error signal during frequency reference loss shall be output externally, set H2-01 to H2-03
(multi-function contact output terminal M1-M2, M3-M4, and M5-M6 function selection) to C (frequency reference lost).

Restarting Operation After Transient Error (Auto Restart Function)
If an Inverter error occurs during operation, the Inverter will perform self-diagnosis. If no error is detected, the
Inverter will automatically restart. This is called the auto restart function.
Set the number of auto restarts in constant L5-01.
The auto restart function can be applied to the following errors.
• OC (Overcurrent)
• RH (Braking resistor overheated)
• GF (Ground fault)
• RR (Braking transistor error)
• PUF (DC bus fuse blown)
• OL1 (Motor overload)
• OV (Main circuit overvoltage)
• OL2 (Inverter overload)
• UV1 (Main Circuit Undervoltage, Main Circuit MC Operation Failure)*
• OH1 (Motor overheat)
• PF (Main circuit voltage fault)
• OL3 (Overtorque)
• LF (Output phase failure)
• OL4 (Overtorque)
* When L2-01 is set to 1 or 2 (continue operation during momentary power loss)
If an error that is not listed above occurs, the protection function will operate and the auto restart function will
not work.
Auto Restart External Outputs
To output auto restart signals externally, set H2-01 to H2-03 (multi-function contact output terminals M1-M2,
M3-M4, and M5-M6 function selection) to 1E (auto restart).

The most likely causes of RH (Mounted braking resistor overheating) faults are that the deceleration time is
too short or that the motor regeneration energy is too large. In these cases, lengthen the deceleration time or
replace the Braking Resistor with one with a higher braking capacity.

Inverter Protection
Inverter Overheat Protection
The Inverter is protected against overheating using a thermistor that detects the heatsink temperature.
When the overheat temperature level is reached the inverter output is switched off.
To prevent a suddenly and unexpected stop of the inverter due to an overtemperature, an overheating
pre-alarm can be output. The temperature level for that pre-alarm can be set in constant L8-02. Using constant L8-03 the inverter operation when an overtemperature occurs can be selected.

The fan is ON only when the inverter output is ON, i.e. a voltage is output. This is the factory setting.
1:
The fan is ON whenever the inverter power supply is switched ON.
If L8-10 is set to 0, the turn OFF delay time for the fan can be set in constant L8-11. After a stop command the
inverter waits for this time before switching OFF the cooling fan. The factory setting is 60 sec.
Setting the Ambient Temperature
The overload capability of the inverter depends on the ambient temperature. At ambient temperatures higher

Precautions
Setting Precautions
If multi-function input terminals S3 to S7 are set as follows, operation error OPE03 (Invalid multi-function
input selection) will occur:
• Only either the UP command or DOWN command has been set.
• UP/DOWN commands and Acceleration/Deceleration Ramp Hold have been allocated at the same time.
6-73
Application Precautions
• Frequency outputs using UP/DOWN commands are limited by the frequency reference upper and lower
limits set in constants d2-01 to d2-03. Here, the frequency value from analog frequency reference input A1
becomes the frequency reference lower limit. If using a combination of the frequency reference from terminal A1 and the frequency reference lower limit set in either constant d2-02 or d2-03, the larger limit
value will become the frequency reference lower limit.
• If inputting the run command when using UP/DOWN commands, the output frequency accelerates to the
frequency reference lower limits set in d2-02.
• When using UP/DOWN commands, multi-step operations are disabled.
• When d4-01 (Frequency Reference Hold Function Selection) is set to 1, the frequency reference value
using the UP/DOWN functions is stored even after the power supply is turned OFF. When the power supply is turned ON and the run command is input, the motor accelerates to the frequency reference that has
been stored. To reset (i.e., to 0 Hz) the stored frequency reference, turn ON the UP or DOWN command
while the run command is ON.

Input Terminal Functions
Hold Analog Frequency Using User-set Timing
When one of the constants H1-01 to H1-05 (multi-function contact input terminal S3 to S7 function selection)
is set to 1E (sample/hold analog frequency command), the analog frequency reference will be held from 100
ms after the terminal is turned ON, and operation will continue at that frequency.
The analog value 100 ms after the command is turned ON is used as the frequency reference.

Precautions
When setting and executing sample and hold for analog frequency references, observe the following precautions.
Setting Precautions
When using sample/hold of analog frequency reference, you cannot use the following commands at the same
time. Otherwise operation error OPE03 (invalid multi-function input selection) will occur.
• Acceleration/Deceleration Ramp Hold command
• UP/DOWN command
• Trim Control Increase/Decrease command
Application Precautions
• When performing sample/hold of analog frequency reference, be sure to close the digital input for 100 ms
or more. If the sample/hold time is less than 100 ms, the frequency reference will not be held.
• The frequency reference value that is held will be deleted when the power supply is turned OFF.
6-77
Switching Operation Source to Communication Option Card
The source of frequency reference and RUN command can be switched between a Communication option
card and the sources selected in b1-01 and b1-02. Set one of the constants H1-01 to H1-05 (multi-function
contact inputs S3 to S7 function selection) to 2 to enable operation source switchover.
If a RUN command is active, the switchover will not be accepted.
Setting Precautions
To use the operation source switching function make the following settings:
• Set b1-01 (frequency reference source) to a value different from 3 (option card).
• Set b1-02 (RUN command source) to a value different from 3 (option card).
• Set one of the constants H1-01 to H1-02 to 2.

Jog Frequency Operation without Forward and Reverse Commands
(FJOG/RJOG)
The FJOG/RJOG function operates the inverter at the jog frequency. It can be activated by using the terminal
ON/OFF operation. When using the FJOG/RJOG commands, there is no need to input the RUN command.
To use this function, set one of the constants H1-01 to H1-05 (multi-function contact input terminal S3 to S7
function selection) to 12 (FJOG command) or 13 (RJOG command).

Application Precautions
• Jog frequencies using FJOG and RJOG commands have the priority over other frequency references.
• When both FJOG command and RJOG commands are ON for 500 ms or longer at the same time, the
Inverter stops according to the setting in b1-03 (stopping method selection).
Stopping the Inverter on External Device Errors (External Error Function)
The external error function activates the error contact output and stops the Inverter operation. Using this function the inverter operation can be stopped on peripheral devices break down or other errors. The digital operator will display EFx (External error [input terminal Sx]). The x in EFx shows the number of the terminal at
which the external error signal is input. For example, if an external error signal is input to terminal S3, EF3
will be displayed.
To use the external error function, set one of the values 20 to 2F in one of the constants H1-01 to H1-05
(multi-function contact input terminal S3 to S7 function selection).
Select the value to be set in H1-01 to H1-05 from a combination of any of the following three conditions.
• Signal input level from peripheral devices
• External error detection method
• Operation during external error detection

Using MEMOBUS Communications
You can perform serial communications with Programmable Logic Controls (PLCs) or similar devices using
the MEMOBUS protocol.
MEMOBUS Communications Configuration
MEMOBUS communications are configured using 1 master (PLC) and a maximum of 31 slaves. Serial communications between master and slave are normally started by the master and the slaves respond.
The master performs serial communications with only one slave at a time. Consequently, you must set the
address of each slave before, so that the master can perform serial communications using that address. A slave
that receives a command from the master performs the specified function and sends a response to the master.

Error Check
Errors during communications are detected using CRC-16 (cyclic redundancy check, checksum method).
The result of the checksum calculation is stored in a data-word (16 bit), which starting value is FFFH. The
value of this word is manipulated using Exclusive OR- and SHIFT operations together with the data package
that should be sent (slave address, function code, data) and the fixed value A001H. At the end of the calculation the data-word contains the checksum value.
The checksum is calculated in the following way:
1. The starting value of the 16 Bit data-word, that is used for the calculation, has to be set to FFFFH.
2. An Exclusive OR operation has to be performed with the starting value and the slave address.
3. The result has to be shifted to the right until the overflow bit becomes 1.
4. When this bit becomes 1, an Esclusive OR operation with the result of step 3 and the fix value A001H has
to be performed.
5. After 8 shift operations (every time when the overflow bit becomes 1, an Exclusive OR like in step 4 has to
be done), perform an Exclusive OR operation with the result of the former operations and the next data
package (8 bit function code). Again the result of this operation has to be shifted 8 times and if needed it
has to be interconnected with the fix value A001H using an Exclusive OR operation.
6. The same steps have to be performed with the data, first with the higher byte and then with the lower byte
until all data are proceeded.
7. The result of these operations is the checksum. It consists of a high and a low byte.

slave address 02H (0000 0010) and the function code 03H (0000 0011). The resulting CRC-16 code is D1H
for the lower and 40H for the higher byte. The example calculation in this example is not done completely
(normally data would follow the function code).

MEMOBUS Message Example
An example of MEMOBUS command/response messages is given below.
Reading Inverter Memory Register Contents
The content of maximum 16 inverter memory registers can be readout at a time.
Among other things the command message must contain the start address of the first register that is to be read
out and the quantity of registers that should be read out. The response message will contain the content of the
first and the consecutive number of registers that has been set for the quantity.
The contents of the memory register are separated into higher 8 bits and lower 8 bits.
The following tables show message examples when reading status signals, error details, data link status, and
frequency references from the slave 2 Inverter.

Writing to Multiple Inverter Memory Registers
The writing of inverter memory registers works similar to the reading process, i.e. the address of the first register that is to be written and the quantity of to be written registers must be set in the command message.
The to be written data must be consecutive, starting from the specified address in the command message. The
data order must be higher 8 bits, then lower 8 bits. The data must be in memory register address order.
The following table shows an example of a message where a forward operation has been set with a frequency
reference of 60.0 Hz for the inverter with the slave address 01H.

ENTER Command
When writing constants to the Inverter from the PLC using MEMOBUS communications, the constants are
temporarily stored in the constant data area in the Inverter. To enable these constants in the constant the
ENTER command must be used.
There are two types of ENTER commands: ENTER commands that enable constant data in RAM, and
ENTER commands that write data to EEPROM (non-volatile memory) in the Inverter at the same time as
enabling the data in RAM.
The following table shows the ENTER command data. ENTER command data can only be written.
The ENTER command is enabled by writing 0 to register number 0900H or 0910H.
Register No.
0900H
Write constant data to EEPROM, RAM is refreshed
0910H
Constant data are not written to EEPROM, but refreshed in RAM only.
INFO
6-98
Contents
The maximum number of times you can write to EEPROM is 100,000. Do not frequently execute ENTER
commands (0900H) that write into EEPROM.
The ENTER command registers are write-only. Consequently, if these registers should be read out, the register address will become invalid (Error code: 02H).

Slave Not Responding
In the following cases, the slave will ignore the write function.
• When a communications error (overrun, framing, parity, or CRC-16) is detected in the command message.
• When the slave address in the command message and the slave address in the Inverter do not agree.
• When the gap between two blocks (8 bit) of a message exceeds 24 bits.
• When the command message data length is invalid.
Application Precautions
If the slave address specified in the command message is 0, all slaves execute the write function, but do not
return response messages to the master.
INFO
6-99
Self-Diagnosis
The Inverter has a built-in function for self-diagnosing the functioning of the serial communication interface
circuits. This function is called the self-diagnosis function. It uses the connected communications parts of the
send and receive terminals to receive data sent by the Inverter and thereby to check if communication is performed normally.
To perform the self-diagnosis function use the following procedure.
1. Turn ON the inverter power supply, and set 67 (communications test mode) in constant H1-05 (Terminal
S7 Function Selection).
2. Turn OFF the inverter power supply.
3. Perform the wiring according to Fig 6.63.
4. Turn ON the terminating resistance. (Turn ON pin 1 on DIP switch 1.)
5. Turn ON the inverter power supply.
Fig 6.63 Communication Terminals Wiring for Self-Diagnosis
During normal operation, the Digital Operator displays “PASS” on the display.
If an error occurs, a “CE” (MEMOBUS communications error) alarm will be displayed on the Digital Operator, the error contact output will be turned ON, and the Inverter operation ready signal will be turned OFF.

Using the Timer Function
The multi-function digital input terminals S3 to S7 can be used as timer function input terminals, and
multi-function output terminals M1-M2, M3-M4, and M5-M6 can be used as timer function output terminals.
By setting the delay time, you can prevent chattering of the sensors and switches.
• Set one of the constants H1-01 to H1-05 (multi-function contact input terminal S3 to S7) to 18 (timer func-
tion input).
• Set H2-01 to H2-03 (multi-function output terminals M1-M2, M3-M4, and M5-M6 function selection) to
12 (timer function output).

Using PID Control
PID control is a method of making the feedback value (detection value) match the set target value. By combining proportional control (P), integral control (I), and differential control (D), you can even control system with
load fluctuation.
The characteristics of the PID control operations are given below.
P element
The output of a P-element is proportional to the input (deviation). With using a P-element
alone it is not possible to eliminate the deviation completely.
I element
The output of an I-element is the time-integral of the input (deviation). With using a P-element and an I-element together the deviation can be eliminated completely.
D element
The output of a D-element is the derivative of the input (deviation). By adding a D-element
the response can be improved rapidly.
PID Control Operation
To understand the differences between the PID control operations P, I, and D, the output share of each operation is shown in the following diagram when the deviation (i.e., the difference between the target value and
feedback value) is fixed.

PID Target Value Input Methods
Select the PID control target value input method according to the setting in b1-01 (Reference Selection).
Normally, the frequency reference selected in b1-01 is the PID target value, but you can also set the PID target
value as shown in the following table.
PID Target Input Method
Setting Conditions
Multi-Function Analog Terminal A2 Input
Set H3-09 to C (PID target value). Also, be sure to set H6-01 (pulse train input function
selection) to 1 (PID feedback value).
MEMOBUS register 0006H
Set MEMOBUS bit 1 in register address 000FH to 1 (enable/disable PID target value
from communications) to be able to use register number 0006H as the PID target value.
Pulse train input
Set H6-01 to 2 (PID target value).
Constant setting
If b5-18 is set to 1 the value in b5-19 becomes the PID target value.
If the PID function is used, the frequency reference value becomes the target value, which is set and shown
in Hz on the operator. Nevertheless, internally the PID target value is used in percent. I.e. the following
formula is used:

Suppressing Short Cycle Vibration
If vibration occurs when the vibration cycle duration is short, and the cycle duration is almost identical to the
differential time (D) set value, the differential operation is too strong. Shorten the differental time (D) to suppress the vibration.
If vibration continues even when the differential time (D) is set to 0.00 (D control disabled), reduce the proportional gain (P), or increase the PID primary delay time constant.

Setting Precautions
• In PID control, the b5-04 constant is used to prevent the calculated integral control value from exceeding a
specified amount. When the load varies rapidly, Inverter response is delayed, and the machine might get be
damaged or the motor may stall. In this case, reduce the set value to speed up Inverter response.
• The b5-06 constant is used to prevent the output value of the the PID control calculation from exceeding a
specified amount. The value is set taking the maximum output frequency as 100%.
• The b5-07 constant is used to adjust PID control offset. The value is set in increments of 0.1%, taking the
maximum output frequency to be 100%.
• Set the filter time constant for the PID control output in b5-08. Enable this constant to prevent machinery
resonance when machinery friction is great, or rigidity is poor. In this case, set the constant to be greater
than the resonance frequency cycle duration. Increase this time constant to reduce Inverter responsiveness.
• Using b5-09, the PID output polarity can be inverted. If now the PID target value increases the output fre-
quency will be lowered. This function is usable e.g. for vacuum pumps.
• Using b5-10, you can apply a gain to the PID control output. Enable this constant to adjust the amount of
compensation if adding PID control output to the frequency reference as compensation (b5-01 = 3/4).
• When PID control output is negative, you can use constant b5-11 to determine what happens to the inverter
output. When b1-04 (Prohibition of Reverse Operation) is set to 1 (enabled), however, the PID output limited to 0.
• Using the b5-17 constant the PID target value can be raised or lowered with an accel./decel. ramp function
(PID soft starter).
The normally used accel./decel. function (C1- constants) is allocated after PID control so that, depending on the settings, resonance with the PID control and hunting in the machinery may occur. Using b5-17
this behaviour can be prevented.
The PID soft starter function can also be disabled or enabled using a multifunction digital input (H1-
has to be set to 34).

Individual Functions
PID Feedback Loss Detection
When performing PID control, be sure to use the PID feedback loss detection function. Otherwise if the PID
feedback gets lost, the Inverter output frequency may accelerate to the maximum output frequency.
When b5-12 is set to 1 and the PID feedback value falls below the PID feedback loss detection level (b5-13)
for a time longer than the PID feedback loss detection time (b5-14), a Fbl alarm (Feedback loss) will be displayed at the operator and inverter operation is continued.
When the same happens and b5-12 is set to 2 a Fbl fault will be displayed on the digital operator and the
inverter operation will be stopped. The motor coasts to stop and the fault contact is operated.
The time chart for PID feedback loss detection is shown below.

PID Sleep
The PID sleep function stops the Inverter when the PID output value falls below the sleep operation level
(b5-15) for the sleep operation time set in parameter b5-16 or longer. The inverter operation will resume, if the
PID output value exceeds the sleep operation level for the time set in parameter b5-16 or longer.
When PID control is disabled, the PID sleep function is also disabled. When using the PID sleep function,
select decelerate to stop or coast to stop as the stopping method.

Adjusting Energy-saving Control
The method of adjusting the energy-saving control function depends on the control method. Refer to the following when making adjustments.
V/f Control Method
In V/f control the voltage for optimum motor efficiency is calculated and becomes the output voltage reference.
• b8-04 (Energy-saving Coefficient) is preset assuming that motor and inverter capacity are the same. If the
inverter capacity differs from the motor capacity, set the motor capacity in E2-11 (Motor Rated Output
Power). Also, adjust b8-04 in steps of 5 % until the output power reaches its minimum. The higher the
energy-saving coefficient, the higher is the output voltage.
• To improve the responsiveness when the load fluctuates, reduce the power detection filter time constant
b8-05. If b8-05 is set too small, however, the motor rotations may become unstable under light load conditions.
• Motor efficiency varies due to temperature fluctuations and differences in motor characteristics. Conse-
quently the motor efficiency has to be controlled. To have optimized efficiency, the search operation varies the output voltage. Constant b8-06 (Search Operation Voltage Limiter) limits the range for the voltage
search operation. For 200 V Class Inverters, a range of 100% is equal to 200 V and for 400 V Class Inverters a range of 100% is equal to 400 V. Set to 0 to disable the search operation voltage limiter.
Open loop vector control
In open loop vector control, the slip frequency is controlled so that motor efficiency is maximized.
• Taking the motor rated slip for the base frequency as optimum slip, the inverter calculates the slip for the
optimum motor efficiency depending on the output frequency. In vector control, be sure to perform autotuning, and set the motor rated slip.
• If hunting occurs when energy-saving control is used in vector control, reduce the set value in b8-02
(Energy-saving Gain), or increase the set value in b8-03 (Energy-saving Filter Time Constant).
6-112
Individual Functions
Field Weakening
The field weakening function is used to lower the output voltage when the motor load changes to a low level
(no load). Thereby energy can be saved and motor audible noise is reduced.
Note that this function is designed for usage with only one low load condition that not changes. If the low
load condition changes, the field weakening function can not be optimized. In this case the energy saving
function should be preferred.
The function can be activated using a multifunction input. Therefore set one of the constants H1-01 to H1-05
to 63.
Field weakening can only be used in V/f control.

Setting the Field Weakening Level (d6-01)
To set the field weakening level run the motor under low load condition and activate the field weakening
function using a multifunction input. Monitor the output current and raise or lower the field weakening level
until the output current reaches it’s minimum value.
Observe the following:
• Constant d6-01 can not be changed during operation (i.e. a RUN command is input).
• If the field weakening level is set too low, the motor may stall.
Multifunction Input Settings: H1-01 to H1-05 (Terminal S3 to S7)

• If one of the constants H1-01 to H1-05 is set to “63”, the field weakening function can be activated switch-
ing the terminal input to ON.

setting for E1-08 will be disregarded.
Always ensure that the four frequencies are set in
the following manner:
E1-04 (FMAX) ≥ E1-06 (FA)
&gt;E1-07 (FB) ≥ E1-09 (FMIN)
Set only to fine-adjust V/f for the output range.
Normally, this setting is not required.

Individual Functions
Setting Inverter Input Voltage
Set the Inverter input voltage correctly in E1-01 so that it matches the power supply voltage. This set value
will be the reference value for the protection functions and similar functions (overvoltage level, stall level).
Setting V/f Pattern
The V/f pattern can be selected using constant E1-03. There are two methods of setting the V/f pattern: Select
one of the 15 preset pattern types (set value: 0 to E), or set a user-defined V/f pattern (set value: F).
The factory setting for E1-03 is F.
To select one of the existing patterns, refer to the following table.

Application
These patterns are used in general applications where the load torque is fixed, regardless of rotation speed, e.g. for linear
transport systems.
These patterns are used for loads with
torque proportional to the square or cube of
the rotation speed, such as fans and pumps.
Select a high startup torque V/f pattern only
in the following cases.
• The wiring distance between Inverter and
motor is large (approx. 150 m min.)
• A large torque is required at startup
• An AC reactor is inserted in the Inverter
input or output.
This pattern is used for frequencies of 60
Hz or higher. A fixed voltage is applied.

When E1-03 is set to F (User-defined V/f pattern), you can set constants E1-04 to E1-10. If E1-03 is set to
anything other than F, you can only read constants E1-04 to E1-10. If the V/f characteristics are linear, set
E1-07 and E1-09 to the same value. In this case, E1-08 will be ignored.

When the setting is to user-defined V/f pattern, beware of the following points:
• When changing control method, constants E1-07 to E1-10 will change to the factory settings for that
control method.
• Be sure to set the four frequencies as follows:

Setting Motor 2 Constants
The E4- constants are for setting the motor constants for motor 2. In vector control mode the motor constants are set automatically during autotuning. If the autotuning does not complete normally, set them manually (refer to Page 6-115, Manual Settings of the Motor Constants).
Note: Autotuning for motor 2 can only be performed if one multifunction input H1- is set to 16 (Motor 2
selection). Otherwise motor 2 cannot be selected during autotuning (T1-00 will not be shown).

Selecting the Motor 2 Control Method (E3-01)
Using constant E3-01 the control method for motor 2 can be selected.
• The setting of this constant affects the autotuning function. If V/f or V/f with PG is selected the only pos-
sible autotuning method will be stationary autotuning for line-to-line resistance.
Setting the V/f Pattern Characteristic
The principle of setting the V/f pattern 2 is the same as for V/f pattern 1. Please refer to Pages 6-117pp. for
details.
Note: The V/f pattern 2 settings are only used for motor 2, i.e. motor 2 has to be selected using a multifunction input (setting 16).

Kinetic Energy Buffering (KEB)
The kinetic energy buffering (KEB) function can be used to decelerate to stop after a sudden power loss using
the kinetic energy of the rotating machine to maintain the DC bus voltage. Thereby an uncontrolled coasting
of a machine can be prevented. The function can only be activated using a multifunction input that normally
is operated by a voltage drop relay. A wiring example is shown in Fig. 6.70.

* 1. The factory setting depends upon the inverter capacity. The value for a 200 V class inverter of 0.4 kW is given.
* 2. If the setting is 0, the axis will accelerate to the specified speed over the specified acceleration time (C1-01 to C1-08).
Setting the Momentary Power Loss Detection (L2-01)
• L2-01 = 0
The inverter trips with undervoltage fault (UV1).
• L2-01 ≠ 0
The inverter decelerates the motor to stop using the KEB deceleration time (L2-06).
Setting the Undervoltage Level (L2-05)
This constant sets the voltage level for the DC bus at which a DC bus undervoltage (UV, UV1) is detected.
Normally there is no need to change this setting.
6-124
Individual Functions
Adjusting the KEB Deceleration Time (L2-06)
Sets the time that is used to decelerate to stop when a KEB command is input.
To set up this constant do the following:
• Increase L2-06 until a UV1 fault is detected during deceleration. (If L2-01 is set to 2, no UV1 will be
detected, but the motor will start to coast when the DC bus voltage drops too much.) The highest setting
value of L2-06, at which no UV1 is detected will be the maximum KEB deceleration time.
• Decrease L2-06 until a DC bus overvoltage (OV) is detected. The lowest setting value of L2-06, at which
no OV is detected, will be the minimal KEB deceleration time.
• Set a value for L2-06 that is somewhere in the middle between the maximum and the minimum KEB dece-
leration time.
Setting the Momentary Recovery Time (L2-07)
This constant can be used to set the time to recover to the set frequency reference if the power supply returns
while the KEB function is active. Note the following:
• The set time in L2-07 is the time that is taken to accelerate from the momentary frequency when the power
supply returns to the frequency reference value. (It works not like the normal accel. function.).
• If L2-07 is set to 0 sec. (factory setting) the normal acceleration times set in the C1- constants are
used.
Adjusting the Frequency Reduction Gain at KEB Start (L2-08)
Normally there is no need to change this setting.
• Increase the setting if an undervoltage fault occurs right after KEB start.
• Decrease the setting if an overvoltage fault occurs right after KEB start.
Multifunction Input Settings: H1-01 to H1-05 (Terminal S3-S7)
KEB Command NC: “65”
• Storing this setting for one of the constants H1-01 to H1-05, the KEB function can be activated using a NC
contact.
KEB command NO: “66”
• Using this setting for one of the constants H1-01 to H1-05, the KEB function can be activated using a NO
contact.
6-125
High Slip Braking
If the load inertia is large the high slip braking function can be used to shorten the deceleration time compared
to the normal deceleration time without using a braking option (braking resistor, braking resistor unit).
The function must be activated by a multifunction input.
Note:
•
The HSB function is not comparable with the normal deceleration function. It does not use a ramp
function.
•
HSB should not be used at normal operation instead of a deceleration ramp.

Adjusting the HSB Deceleration Frequency Width (N3-01)
This constant sets the step width that is used for lowering the output frequency to achieve a large negative slip
and thereby to brake the motor.
Normally no adjustments should be necessary. Increase the value if DC bus overvoltage faults occur.
Adjusting the HSB Current Limit (N3-02)
The setting of constant N3-02 limits the output current while high slip braking is active. The current limit
affects the achievable deceleration time.
The lower the current limit the longer is the deceleration time.
Setting the HSB Dwell Time at Stop (N3-03)
At the end of a high slip braking the output frequency is held at the minimum output frequency for the time set
in N3-03. Increase the time when the motor coasts further on after HSB.
Setting the HSB Overload Time (N3-04)
N3-04 sets the HSB overload time. If the output frequency does not change for any reason although a HSB
command is given, an OL7 fault will be displayed and the fault contact will operate.
Multifunction Input Settings: H1-01 to H1-05 (Terminal S3 to S7)
High Slip Braking: “68”
If one of the multifunction inputs is set to “68” it can be used to activate the HSB function. The inverter will
brake the motor immediately after the HSB command was given. HSB cannot be stopped, i.e. the operation
cannot be resumed while HSB.

Monitor Selection (o1-01)
Using constant o1-01 the third monitor item that is displayed in drive mode can be selected. This function has
no effect on the optional LCD-operator (JVOP-160).
Monitor Display when the Power Supply is Turned ON (o1-02)
Using constant o1-02 the monitor item (U1-) that is to be displayed on the Digital Operator when the
power supply is turned ON can be selected.
Changing Frequency Reference and Display Units o1-03)
Set the Digital Operator frequency reference and display units using constant o1-03. The setting in o1-03 will
affect the display units of the following monitor items:
• U1-01 (Frequency Reference)
• U1-02 (Output Frequency)
• U1-05 (Motor Speed)
• U1-20 (Output Frequency after Soft Start)
• d1-01 to d1-17 (Frequency references)
Disabling the LOCAL/REMOTE Key (o2-01)
Set o2-01 to 0 to disable the LOCAL/REMOTE Key on the Digital Operator.
If the key is disabled, it cannot be used anymore to switch over the frequency reference source or the RUN
command source between LOCAL and REMOTE.
6-128
Digital Operator Functions
Disabling the STOP Key (o2-02)
This constant is used to set whether the STOP key on the operator is active during remote control (b1-02 ≠ 0)
or not.
If o2-02 is set to 1, a STOP command from the operators STOP key will be accepted. If o2-02 is set to 0 it will
be disregarded.
Initializing Changed Constant Values (o2-03)
You can save the current Inverter constant setting values as user-set constant initial values. Therefore constant
o2-03 has to be set to 1.
To initialize the Inverter constants using the user-set initial values in memory set constant A1-03 to 1110. To
clear the user-set initial values in memory, set o2-03 to 2.
Setting the Frequency Reference using the UP and DOWN Keys without Using the
Enter Key (o2-05)
This function is active when frequency references are input from the Digital Operator. When o2-05 is set to 1,
you can increment and decrement the frequency reference using the UP and DOWN keys without using the
Enter key.
Operation Selection when the Digital Operator is Disconnected (o2-06)
This function selects the operation when the digital operator gets disconnected when a RUN command is
active.
If o2-06 is set to 0 the operation is continued.
If o2-06 is set to 1 the output is switched off and the motor coasts to stop. The fault contact is operated. When
the operator is reconnected an OPR (Operator disconnected) is shown.
Cumulative Operation Time (o2-07 and o2-08)
The inverter has a function that counts the operation time of the inverter cumulatively.
Using constant o2-07 the cumulative operation time can be changed, e.g. after a replacement of the control
board. If constant o2-08 is set to 0 the inverter counts the time whenever the power supply is switched ON. If
o2-08 is set to 1 the time when a RUN command is active is counted only. The factory setting is 0.
Initialize Mode (o2-09)
This function is used to change the factory settings of several constants. If o2-09 is set to 1 the constants will
be set to US standards. If o2-09 is set to 2 the constants will be set to European standards. After changing this
setting the inverter has to be reinitialized using constant A1-03.
Cooling Fan Operation Time (o2-10)
This function counts the operating time of the inverter mounted fan cumulatively.
Using constant o2-10 the counter can be reset, e.g. when the fan was replaced.
Fault Trace Initialize (o2-12)
This function can be used to initialize the fault trace by setting constant o2-12 to 1.
6-129
Copying Constants
The Digital Operator can perform the following three functions using a built-in EEPROM (non-volatile memory).
• Store Inverter constant set values in the Digital Operator (READ)
• Write constant set values stored in the Digital Operator to the Inverter (COPY)
• Compare constant set values stored in the Digital Operator with Inverter constants settings (VERIFY)

Using PG Speed Control Card
There are four types of PG Speed Control Card that can be used in V/f control with PG.
• PG-A2: A-phase (single) pulse input, compatible with open collector.
• PG-B2: A/B-phase pulse input, compatible with complimentary outputs.
• PG-D2: A-phase (single) pulse input, compatible with line drivers (RS-422).
• PG-X2: A/B/Z-phase pulse input, compatible with line drivers (RS-422).
For the mounting instructions, specifications and connection diagrams refer to page 2-32.
Setting Number of PG Pulses (F1-01)
Set the number of PG (Pulse Generator/Encoder) pulses in pulses/rotation.
Suit the PG Rotation Direction and Motor Rotation Direction (F1-05)
Constant F1-05 suits the PG rotation direction to the motor rotation direction. If the motor is rotating forwards,
set whether it is A-phase leads or B-phase leads. Make this setting when using PG-B2 or PG-X2.

Setting Number of Gear Teeth Between PG and Motor (F1-12 and F1-13)
If there are gears between the motor and PG, the gear ratio can be set using F1-12 and F1-13.
When the number of gear teeth has been set, the number of motor rotations within the Inverter is calculated
using the following formula.
No. of motor rotations (r/min.) = No. of input pulses from PG &times; 60 / F1-01 &times; F1-13 (No. of gear teeth on PG
side) / F1-12 (No. of gear teeth on motor side)
Integral Operation During Acceleration and Deceleration (F1-07)
You can select whether to enable or disable integral operation during acceleration and deceleration.
To make the motor speed matching the frequency reference as closely as possible even during acceleration and
deceleration, set F1-07 to 1. Refer also to Page 6-40
If F1-01 is set to 1, overshoot or undershoot may occur easily immediately after acceleration and deceleration. To minimize the possibility of overshoot or undershoot occurring, set F1-01 to 0.
IMPORTANT
Setting PG Pulse Monitor Output Dividing Ratio (F1-06)
This function is enabled only when using PG speed control card PG-B2. Set the dividing ratio for the PG pulse
monitor output. The set value is expressed as n for the higher place digit, and m for the two lower place digits.
The dividing ratio is calculated as follows:
Dividing ratio = (1 + n)/m (Setting range) n: 0 or 1, m: 1 to 32
F1-06 =

n
m
The dividing ratio can be set within the following range: 1/32 ≤ F1-06 ≤ 1. For example, if the dividing ratio is
1/2 (set value 2), half of the number of pulses from the PG are output at the pulse monitor.

Options
Detecting PG Open Circuit (F1-02 and F1-14)
Constant F1-02 select the stopping method when a PG disconnection is detected.
PG open (PGO) is only detected when the inverter is running at least with a frequency reference higher than
1% of the maximum output frequency or above the minimum frequency (E1-09) and the PG feedback signal is
missing for the time set in F1-14 or longer.
Detecting Motor Overspeed (F1-03, F1-08 and F1-09)
An error is detected when the number of motor rotations exceeds the set limit. An overspeed (OS) is detected
when the motor speed continues to exceed the set frequency value in F1-08 for a time longer than set in F1-09.
After detecting an overspeed (OS), the Inverter stops according to the setting in F1-03.
Detecting Speed Difference between the Motor and Speed Reference (F1-04, F1-10
and F1-11)
An error is detected when the speed deviation (i.e., the difference between the speed reference and the actual
motor speed) is too great. Speed deviation (DEV) is only detected after a speed agreement (speed reference
and actual motor speed are within the setting range of L4-02) and if a speed deviation higher than the set value
in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected, the Inverter stops
according to the setting in F1-04.

Protective and Diagnostic Functions
This section describes the alarm functions of the Inverter. The alarm functions include fault detection,
alarm detection, operation error detection, and autotuning error detection.
Fault Detection
When the Inverter detects a fault, the fault contact output operates, and the Inverter output is switched OFF
causing the motor to coast to stop. (The stopping method can be selected for some faults.) A fault code is displayed on the Digital Operator.
When a fault has occurred, refer to the following table to identify the fault and to correct the causes.
Use one of the following methods to reset the fault before restarting the Inverter:
• Set a multi-function contact input (H1-01 to H1-05) to 14 (Fault Reset) and turn ON the error reset signal.
• Press the RESET key on the Digital Operator.
• Turn the main circuit power supply OFF and then ON again.

H1-05). If the constant write enable input is OFF, the constants cannot be changed. Turn it ON and then set the
constants.
Passwords do not match. (Only when a password is set.)
If the constant A1-04 (Password) and A1-05 (Password Setting) numbers are different, the constants for the
initialize mode cannot be changed. Reset the password.
If you cannot remember the password, display A1-05 (Password Setting) by pressing the Reset key and the
Menu key simultaneously while in the A1-04 display. Then reset the password. (Input the reset password in
constant A1-04.)
OPE01 through OPE11 is displayed.
The set value for the constant is wrong. Refer to Operation Errors in this chapter and correct the setting.
CPF00 or CPF01 is displayed.
This is a Digital Operator communications error. The connection between the Digital Operator and the
Inverter may be faulty. Remove the Digital Operator and then re-connect it.

If the Motor Does Not Operate
The motor does not operate when the RUN key on the Digital Operator is pressed.
The following causes are possible.
The operation method setting is wrong.
If constant b1-02 (Operation Method Selection) is set to 1 (control circuit terminal), the motor will not operate
when the RUN key is pressed. Either press the LOCAL/REMOTE key* to switch to Digital Operator operation or set b1-02 to 0 (Digital Operator).
The LOCAL/REMOTE key can be enabled or disabled by setting o2-01. It is enabled when the drive mode is
entered and o2-01 is set to 1.
INFO
The frequency reference is too low.
If the frequency reference is set below the frequency set in E1-09 (Minimum Output Frequency), the Inverter
will not operate.
Raise the frequency reference to at least the minimum output frequency.
There is a multi-function analog input setting error.
If multi-function analog input H3-09 is set to 1 (frequency gain), and if no voltage (current) is input, then the
frequency reference will be zero. Check to be sure that the set value and analog input value are correct.
The motor does not operate when an external operation signal is input.
The following causes are possible.
The Inverter is not in drive mode.
If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the MENU key make
the DRIVE indicator flash, and enter the drive mode by pressing the DATA/ENTER key. The DRIVE indicator will light up when drive mode is entered.
The operation method selection is wrong.
If constant b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an external operation signal is input. Set b1-02 to 1 (control circuit terminal) and try again.
The motor will also not operate if the LOCAL/REMOTE key has been pressed to switch to Digital Operator
operation. In that case press the LOCAL/REMOTE key* again to return to the original setting.
The LOCAL/REMOTE key can be enabled or disabled by setting o2-01. It is enabled when the drive mode is
entered and o2-01 is set to 1.
INFO
7-16
Troubleshooting
A 3-wire control in effect.
The input method for a 3-wire control is different than when operating by forward/stop and reverse/stop (2wire control). If a 3 wire control is selected, the motor will not operate when a wiring that is suitable for 2-wire
control is used. When using a 3-wire control, refer to the wiring example and timing chart on Page 6-11 and
input the proper signals.
When using a 2-wire control, set the multi-function input terminal (H1-01 through H1-05, terminals S3 to S7)
to a value other than 0.
The frequency reference is too low.
If the frequency reference is set below the frequency set in E1-09 (Minimum Output Frequency), the Inverter
will not operate. Raise the frequency reference to at least the minimum output frequency.
There is a multi-function analog input setting error.
If H3-09 (Analog Input A2 Function Selection) is set to 1 (frequency gain), and if no voltage (current) is input,
then the frequency reference will be zero. Check to be sure that the set value and analog input value are correct.
The motor stops during acceleration or when a load is connected.
The load may be too heavy. The Inverter has a stall prevention function and an automatic torque boost function, but the motor responsiveness limit may be exceeded if acceleration is too rapid or if the load is too heavy.
Lengthen the acceleration time or reduce the load. Also consider increasing the motor capacity.
The motor only rotates in one direction.
&quot;Reverse run prohibited&quot; is selected. If b1-04 (Prohibition of Reverse Operation) is set to 1 (reverse run prohibited), the Inverter will not accept reverse run commands. To use both forward and reverse operation, set b104 to 0.
If the Direction of the Motor Rotation is Reversed
If the motor operates in the wrong direction, the motor output wiring is faulty. When the Inverter T1(U),
T2(V), and T3(W) are properly connected to the motor T1(U), T2(V), and T3(W), the motor operates in a forward direction when a forward run command is executed. The forward direction depends on the manufacturer
and the motor type, so be sure to check the specifications.
The direction of rotation can be reversed by switching two wires among U, V, and W, or use constant b1-04 to
reverse output direction (in V/f mode only).
If the Motor Does Not Put Out Torque or If Acceleration is Slow
The torque limit has been reached.
When a torque limit has been set in constants L7-01 to L7-04, no torque will be output beyond that limit. This
can cause the torque to be insufficient, or the acceleration time to be too long. Check to be sure that the value
set for the torque limit is suitable.
If torque limits have been set for the multi-function analog input (H3-09 = 10 to 12 or 15), check to be sure
that the analog input value is suitable.
7-17
The stall prevention level during acceleration is too low.
If the value set for L3-02 (Stall Prevention Level during Acceleration) is too low, the acceleration time will be
very long. Check to be sure that the set value is suitable.
The stall prevention level during running is too low.
If the value set for L3-06 (Stall Prevention Level during Running) is too low, the speed may drop already at
low output torque. Check to be sure that the set value is suitable.
Autotuning has not been performed for vector control
Vector control will not work properly if autotuning has not been performed. Perform autotuning, or set the
motor constants through calculations.
If the Motor Operates at Higher Speed than the Frequency Reference
The analog frequency reference bias or gain setting is wrong.
The frequency reference bias or gain set in constant H3-03 or H3-02 influence the frequency reference. Check
to be sure that these set values are suitable.
A signal is being input to the multifunction analog input terminal A2.
When “0” (frequency bias) is set for constant H3-09 (Multi-function Analog Input Terminal A2 Function
Selection), a frequency corresponding to the terminal A2 input voltage (current) is added to the frequency reference. Check to be sure that the set value and analog input value are suitable.
If the Slip Compensation Function Has Low Speed Precision
If speed control accuracy is low using the slip compensation function, maybe the slip compensation limit has
been reached. The slip compensation function does not work beyond the slip compensation limit set in constant C3-03. Check to be sure that the set value is suitable.
If There is Low Speed Accuracy at High-speed Rotation in Open-loop
Vector Control Mode
The Inverter's maximum output voltage is determined by its input voltage. (For example, if 200 VAC is input,
then the maximum output voltage will be 200 VAC.) If, as a result of vector control, the output voltage reference value exceeds the Inverter output voltage maximum value, the speed control accuracy will decrease. Use
a motor with a low rated voltage (i.e., a special motor for use with vector control).
7-18
Troubleshooting
If Motor Deceleration is Slow
The deceleration time is long even when braking resistor is connected.
The following causes are possible.
&quot;Stall prevention during deceleration enabled&quot; is set.
When braking resistor is connected, set constant L3-04 (Stall Prevention Selection during Deceleration) to 0
(disabled) or 3 (with braking resistor). When this constant is set to 1 (enabled), braking resistor does not fully
functions.
The deceleration time setting is too long.
Check the deceleration time setting (constants C1-02, C1-04, C1-06, and C1-08).
Motor torque is insufficient.
If the constants are correct and there is no overvoltage fault, maybe then the motor's power limit is reached.
Consider increasing the motor capacity.
The torque limit has been reached.
When torque limits have been set in constants L7-01 to L7-04, no torque output beyond that limits will be output. This can cause the deceleration time to be too long. Check to be sure that the values set for the torque limits are suitable.
If torque limits have been set for the multi-function analog input terminal A2 Function H3-09 (set value: 10 to
12 or 15), check to be sure that the analog input value is suitable.
If a Vertical-Axis Load Drops When Brake is Applied
(Brake ON/OFF Controlled by Digital Output)
The control sequence baybe incorrect. The Inverter goes into DC injection braking status for 0.5 seconds after
deceleration is completed. (This is the factory-set default.)
To ensure that the brake (controlled by digital output M1-M2) holds, set frequency detection 2 (H2-01 = 5) for
the multi-function contact output terminals (M1 and M2) so that the contacts will turn OFF when the output
frequency is higher than L4-01 (3.0 to 5.0 Hz). (The contacts will turn ON below L4-01.)
There is hysteresis in frequency detection 2 (i.e., a frequency detection width, L4-02 = 2.0 Hz) . Change the
setting to approximately 0.5 Hz if there are load drops during stop. Do not use the multi-function contact output run signal (H2-01 = 0) for the brake ON/OFF signal.
If the Motor Overheats
The load is too big.
If the motor load is too heavy and the motor is used continuously with a torque that exceeds the motor's rated
torque, the motor will overheat. Reduce the load amount by lowering the load. Also consider increasing the
motor capacity.
7-19
The ambient temperature is too high.
The motor rating is determined within a particular ambient operating temperature range. The motor will burn
out if it is run continuously at the rated torque in an environment in which the maximum ambient operating
temperature is exceeded. Lower the motor's ambient temperature to be within the acceptable ambient operating temperature range.
The withstand voltage between the motor phases is insufficient.
When the motor is connected to the Inverter output, a surge is generated between the Inverter output and the
motor coil. Normally the maximum surge voltage is three times the Inverter's input power supply voltage (i.e.,
1,200 V for 400 V class). Be sure to use a motor with a withstand voltage between the motor phases that is
higher than the maximum surge voltage.
Autotuning has not been performed for vector control
Vector control will not work properly if autotuning has not been performed. Perform autotuning, or set the
motor constants through calculations.
If peripheral devices like PLC’s or other are influenced by the starting or
running inverter
If electrical noise is generated by Inverter perform the following countermeasures:
• Change the Inverter's Carrier Frequency Selection (C6-02) to lower the carrier frequency.
• Install an Input Noise Filter at the Inverter's power supply input.
• Install an Output Noise Filter at the Inverter's output.
• Ground the Inverter and motor.
• Separate main circuit wiring from control circuit wiring.
If the Ground Fault Interrupter Operates when a RUN Command is Input
The Inverter performs internal switching, so there is a certain amount of leakage current. This may cause the
ground fault interrupter to operate and cut off the power supply. Change to a ground fault interrupter with a
high leakage detection level (i.e., a sensitivity current of 200 mA or higher, with an operating time of 0.1 s or
more), or one that incorporates high frequencies (i.e., one designed for use with Inverters). It will also help to
some extent to lower the Inverter's Carrier Frequency Selection (C6-02). In addition, remember that the leakage current increases as the cable is lengthened.
7-20
Troubleshooting
If There is Mechanical Oscillation
The machinery is making unusual sounds.
The following causes are possible.
There may be resonance between the mechanical system's characteristic frequency and the
carrier frequency.
If the motor is running with no problems and the machinery is oscillating with a high-pitched whine, it may
indicate that this is occurring. To prevent this type of resonance, adjust the carrier frequency with constants
C6-02 to C6-05.
There may be resonance between a machine's characteristic frequency and the output frequency of the Inverter.
To prevent this from occurring, either use the jump frequency functions in constants d3-01 to d3-04 or install
rubber padding on the motor base to reduce oscillation.
Oscillation and hunting are occurring with open-loop vector control.
The gain and time constant adjustments for the slip and torque compensation may be insufficient. Lower the
gain settings and raise the delay time settings. Also adjust the AFR settings (N2-).
Vector control will not work properly if autotuning has not been performed. Perform autotuning or set the
motor constants through calculations.
Oscillation and hunting are occurring with V/f control.
The gain and time constant adjustments for the slip and torque compensation may be insufficient. Lower the
gain settings and raise the delay time settings. Also adjust the hunting prevention function (N1-).
Oscillation and hunting are occurring with V/f with PG control.
The ASR adjustments may are insufficient. Adjust the speed control loop (ASR) gains and integral times.
If the oscillation cannot be eliminated in this way, set the hunting prevention selection (constant N1-01) to 0
(disabled) and then try adjusting the gain again.
Oscillation and hunting are occurring with PID control.
If there is oscillation or hunting during PID control, check the oscillation cycle and individually adjust P, I,
and D constants. (Refer to Page 6-104pp.)
If the Motor Rotates Even When Inverter Output is Stopped
If the motor rotates even when the Inverter output is stopped, maybe the DC injection braking is insufficient.
If the motor coasts at low speed after a deceleration to stop has been executed, it means that the DC injection
braking is not decelerating enough. Adjust the DC injection braking as follows:
• Increase the constant b2-02 (DC Injection Braking Current) setting.
• Increase the constant b2-04 (DC Injection Braking (initial excitation) Time at Stop) setting.
7-21
If OV (Overvoltage) is Detected When a Fan is Started, or Fan Stalls
Generation of OV (DC bus overvoltage) and stalling can occur if a fan is turning before it is started (e.g.
through the windmill effect).
This can be prevented by slowing fan rotation using DC injection braking before starting the fan. Alternatively
the speed search function can be used to catch the rotating motor.
If Output Frequency Does Not Rise to Frequency Reference
The frequency reference is within the jump frequency range.
When the jump frequency function is used, the output frequency does not change within the jump frequency
range. Check to be sure that the Jump Frequency (constants d3-01 to d3-03) and Jump Frequency Width (constant d3-04) settings are suitable.
The frequency reference upper limit has been reached.
The output frequency upper limit is determined by the following formula:
Maximum Output Frequency (E1-04) &times; Frequency Reference Upper Limit (d2-01) / 100
Check to be sure that the constant E1-04 and d2-01 settings are suitable.

Inverter Application Precautions
Selection
Observe the following precautions in selecting an Inverter.
Installing Reactors
A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity
power transformer (600 kVA or higher) or when switching a compensating capacitor. Excessive peak current
can destroy the convertor section. To prevent this, install a DC or AC reactor (optional) to improve the power
supply power factor.
DC reactors are built into 200 V class Inverters of 22 to 110 kW and 400 V class Inverters of 22 to 300 kW.
If a thyristor convertor, such as a DC drive, is connected in the same power supply system, connect a DC or
AC reactor regardless of the power supply conditions shown in the following diagram.

Fig 10.1
Inverter Capacity
When connecting special motors or multiple motors in parallel to an Inverter, select the Inverter capacity so
that the rated output current of the Inverter is minimum 1.1 times the sum of all the motor rated currents.
Initial Torque
The startup and acceleration characteristics of the motor are restricted by the overload current ratings of the
Inverter that is driving the motor. The torque characteristic generally is different from those when starting a
motor at a normal commercial power supply. If a large initial torque is required, select an Inverter with a
somewhat larger capacity or increase the capacity of both, the motor and the inverter.
Options
Terminals B1, B2, , 1, 2, 3 are for connecting only the options specifically provided by Yaskawa.
Never connect any other devices to these terminals.
10-2
Inverter Application Precautions
Installation
Observe the following precautions when installing an Inverter.
Installation in Enclosures
Either install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants,
or install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so
that the temperature surrounding the Inverter does not go beyond the allowable temperature. Do not install the
Inverter on wood or other combustible materials.
Installation Direction
Mount the Inverter vertically to a wall or other vertical surface.
Settings
Observe the following precautions when making settings for an Inverter.
Upper Limits
The Digital Operator can be used to set high-speed operation up to a maximum of 400 Hz (depends on the carrier frequency). Incorrect settings can be dangerous. Use the maximum frequency setting functions to set
upper limits. (The maximum output frequency is factory-set to 50 Hz.)
DC Injection Braking
The motor can overheat if the DC injection braking current or braking time is set to a too large value.
Acceleration/Deceleration Times
The motor's acceleration and deceleration times are determined by the torque generated by the motor, the load
torque, and the load's inertial moment (GD2/4). If the stall prevention functions are activated during acceleration or deceleration, it might be necessary to increase the acceleration or deceleration time.
To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.
10
10-3
Handling
Observe the following precautions when wiring or performing maintenance for an Inverter.
Wiring Check
The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W.
Check wiring for any mistakes before supplying power. Check all wiring and central sequences carefully.
Magnetic Contactor Installation
Do not start and stop operation frequently with a magnetic contactor installed on the power supply line. Doing
so can cause the Inverter to malfunction. Do not turn the Inverter ON and OFF with a magnetic contactor more
than one time every 30 minutes.
Maintenance and Inspections
After turn OFF the main circuit power supply, always confirm that the CHARGE indicator does not light anymore before performing maintenance or inspections. The voltage remaining in the capacitor may cause electric shock.
10-4
Motor Application Precautions
Motor Application Precautions
Using the Inverter for an Existing Standard Motor
Observe the following precautions when using an Inverter for an existing standard motor.
Low Speed Ranges
Cooling effects diminish in the low-speed range, resulting in an increase of the motor temperature. Therefore,
the motor torque should be reduced in the low-speed range whenever using a fan cooled motor. If 100% torque
is required continuously at low speed, consider using a special inverter or vector motor.
Installation Withstand Voltage
If the input voltage is high (440 V or higher) or the wiring distance is long, the motor insulation voltage must
be considered. Contact your Yaskawa representative for details.
High-speed Operation
When using the motor at a high speed (50 Hz or more), problems may arise in dynamic balance and bearing
durability. Contact your Yaskawa representative for details.
Noise
Noise varies with the carrier frequency. At high carrier frequencies, the noise is almost the same when the
motor is operated with a commercial power supply.
10
10-5
Using the Inverter for Special Motors
Observe the following precautions when using a special motor.
Pole-changing Motor
The rated input current of pole-changing motors differs from that of standard motors. Select an appropriate
Inverter according to the maximum input current of the motor.
Submersible Motor
The rated input current of submersible motors is higher than that of standard motors. Therefore, always select
an Inverter by checking its rated output current. When the distance between the motor and Inverter is long, use
a cable thick enough to connect the motor and Inverter to prevent voltage drop and thereby motor torque
reduction.
Explosion-proof Motor
When an explosion-proof motor is to be used, it must be subjected to an explosion-proof test in conjunction
with the Inverter. This is also applicable when an existing explosion-proof motor is to be operated with the
Inverter. Since the Inverter itself is, however, not explosion-proof, always install it in a safe place.
Gearmotor
The speed range for continuous operation differs according to the lubrication method and motor manufacturer.
In particular, continuous operation of an oil-lubricated motor in the low speed range may result in damaging.
If the motor is to be operated at a speed higher than 50 Hz, consult the manufacturer.
Synchronous Motor
A synchronous motor is not suitable for Inverter control.
Single-phase Motor
Do not use an Inverter for a single-phase motor. The motor should be replaced with a 3-phase motor.
Power Transmission Mechanism (Speed Reducers, Belts and Chains)
If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will
be affected when the motor operates only in the low speed range. The power transmission mechanism will
make noise and experience problems with service life and durability if the motor is operated at low speeds
continuously.
