1. Electric Shock Prevention
WARNING
While power is on or when the inverter is running, do not open the front cover. You
may get an electric shock.
Do not run the inverter with the front cover or wiring cover removed. Otherwise,
you may access the exposed high-voltage terminals or the charging part of the
circuitry and get an electric shock. Also, the inverter's ability to withstand
earthquakes will deteriorate.
Even if power is off, do not remove the front cover except for wiring or periodic
inspection. You may access the charged inverter circuits and get an electric shock.
Before starting wiring or inspection, check to make sure that the 3-digit LED inverter
monitor is off, wait for at least 10 minutes after the power supply has been switched
off, and check to make sure that there are no residual voltage using a tester or the
like.
This inverter must be grounded. Grounding must conform to the requirements of
national and local safety regulations and electrical codes. (JIS, NEC section 250,
IEC 536 class 1 and other applicable standards)
Any person who is involved in the wiring or inspection of this equipment should be
fully competent to do the work.
Always install the inverter before wiring. Otherwise, you may get an electric shock
or be injured.
Perform setting dial and key operations with dry hands to prevent an electric
shock.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise, you may get an electric shock.
Do not change the cooling fan while power is on. It is dangerous to change the
cooling fan while power is on.
When you have removed the front cover, do not touch the connector above the 3-
digit monitor LED display. Otherwise, you get an electrick shock.

2. Fire Prevention
CAUTION
Mount the inverter on an incombustible surface. Installing the inverter directly on or near
a combustible surface could lead to a fire.
If the inverter has become faulty, switch off the inverter power. A continuous flow of
large current could cause a fire.
Do not connect a resistor directly to the DC terminals P, N. This could cause a fire.
3. Injury Prevention
CAUTION
Apply only the voltage specified in the instruction manual to each terminal to
prevent damage, etc.
Always connect to the correct terminal to prevent damage, etc.
Always make sure that polarity is correct to prevent damage, etc.
While power is on or for some time after power-off, do not touch the inverter as it is
hot and you may get burnt.
4. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock,
etc.
(1) Transportation and installation
CAUTION
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the instruction manual.
Do not install or operate if the inverter is damaged or has parts missing.
When carrying the inverter, do not hold it by the front cover or setting dial; it may
fall off or fail.
Do not stand or rest heavy objects on the inverter.
Check the inverter mounting orientation is correct.
Prevent other conductive bodies as screws and metal fragments or other
flammable substance as oil from entering the inverter.
As the inverter is a precision instrument, do not drop or subject it to impact.
Use the inverter under the following environmental conditions: This could cause
the inverter damage.

(2) Wiring
CAUTION
Do not fit capacitive equipment such as power factor correction capacitor, radio
noise filter (option FR-BIF(-H)) or surge suppressor to the output of the inverter.
The connection orientation of the output cables U, V, W to the motor will affect the
direction of rotation of the motor.
(3) Trial run
CAUTION
Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
When the load GD
output current may vary when the output frequency is in the 20Hz to 30Hz range.
If this is a problem, set the Pr.72 "PWM frequency selection" to 6kHz or higher.
(When setting the PWM to a higher frequency, check for noise or leakage current
problem and take countermeasures against it.)
(4) Operation

WARNING
When you have chosen the retry function, stay away from the equipment as it will
restart suddenly after an alarm stop.
The [STOP] key is valid only when the appropriate function setting has been made.
Prepare an emergency stop switch separately.
Make sure that the start signal is off before resetting the inverter alarm. A failure to
do so may restart the motor suddenly.
The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
Do not modify the equipment.
Do not perform parts removal which is not instructed in this manual. Doing so may
lead to fault or damage of the inverter.
A-3
CAUTION
The electronic thermal relay function does not guarantee protection of the motor
from overheating.
Do not use a magnetic contactor on the inverter input for frequent starting/stopping
of the inverter.
Use a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
Take measures to suppress harmonics. Otherwise power supply harmonics from
the inverter may heat/damage the power capacitor and generator.
When a 400V class motor is inverter-driven, please use an insulation-enhanced
motor or measures taken to suppress surge voltages. Surge voltages attributable to
the wiring constants may occur at the motor terminals, deteriorating the insulation of
the motor.
When parameter clear or all clear is performed, reset the required parameters
before starting operations. Each parameter returns to the factory setting.
The inverter can be easily set for high-speed operation. Before changing its
setting, fully examine the performances of the motor and machine.
In addition to the inverter's holding function, install a holding device to ensure safety.
Before running an inverter which had been stored for a long period, always
perform inspection and test operation.
(5) Emergency stop
CAUTION
Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
When the breaker on the inverter primary side trips, check for the wiring fault (short
circuit), damage to internal parts of the inverter, etc. Identify the cause of the trip,
then remove the cause and power on the breaker.
When any protective function is activated, take the appropriate corrective action,
then reset the inverter, and resume operation.
(6) Maintenance, inspection and parts replacement
CAUTION
Do not carry out a megger (insulation resistance) test on the control circuit of the
inverter.
(7) Disposing of the inverter
CAUTION
Treat as industrial waste.
(8) General instructions

Main circuit terminals
1.2.3Wiring instructions
1) Use insulation-sleeved crimping terminals for the power supply and motor cables.
2) Application of power to the output terminals (U, V, W) of the inverter will damage the
inverter. Never perform such wiring.
3) After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter
clean.
When drilling a control box etc., take care not to let wire offcuts enter the inverter.
4) Use cables of the recommended size to make a voltage drop 2% maximum.
If the wiring distance is long between the inverter and motor, a main circuit cable
voltage drop will cause the motor torque to decrease especially at the output of a
low frequency.
5) For long distance wiring, the high response current limit function may be reduced or
the devices connected to the secondary side may malfunction or become faulty
under the influence of a charging current due to the stray capacity of wiring.
Therefore, note the maximum overall wiring length.
6) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components,
which may interfere with the communication devices (such as AM radios) used near
the inverter. In this case, install a FR-BIF(-H) optional radio noise filter (for use on
the input side only) or FR-BSF01 or FR-BLF line noise filter to minimize
interference.
7) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF(-H)
option) on the output side of the inverter.
This will cause the inverter to trip or the capacitor and surge suppressor to be
damaged. If any of the above devices are connected, remove them. (When using
the FR-BIF(-H) radio noise filter with a single-phase power supply, connect it to the
input side of the inverter after isolating the T phase securely.)
8) Before starting wiring or other work after the inverter is operated, wait for at least 10
minutes after the power supply has been switched off, and check that there are no
residual voltage using a tester or the like. The capacitor is charged with high
voltage for some time after power off and it is dangerous.

1.2.5Leakage current and installation of ground leakage
circuit breaker
Due to static capacitances existing in the inverter I/O wiring and motor, leakage
currents flow through them. Since their values depend on the static capacitances,
carrier frequency, etc., take the following countermeasures.
(1) To-ground leakage currents
Leakage currents may flow not only into the inverter's own line but also into the
other line through the ground cable, etc.
These leakage currents may operate ground leakage circuit breakers and ground
leakage relays unnecessarily.
Countermeasures
• If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of the
inverter.
Note that motor noise increases. Selection of Soft-PWM control (Pr. 70) will make it
unoffending. (Factory setting)
• By using earth leakage circuit breakers designed for harmonic and surge
suppression in the inverter's own line and other line, operation can be performed
with the carrier frequency kept high (with low noise).

relay unnecessarily.
Countermeasures
• Use the electronic thermal relay function of the inverter.
• Decrease the carrier frequency. Note that motor noise increases. Selection of
Soft-PWM (Pr. 70) makes it unoffending.
To ensure that the motor is protected against line-to-line leakage currents, it is
recommended to use a temperature sensor to directly detect motor temperature.
Installation and selection of no-fuse breaker
Install a no-fuse breaker (NFB) on the power receiving side to protect the wiring of
the inverter primary side. Select the NFB according to the power supply side power
factor (which depends on the power supply voltage, output frequency and load).
Especially for a completely electromagnetic NFB, one of a slightly large capacity
must be selected since its operation characteristic varies with harmonic currents.
(Check it in the data of the corresponding breaker.) As an ground leakage breaker,
use the Mitsubishi ground leakage breaker designed for harmonics and surge
suppression. (Refer to page 10 for the recommended models.)
CAUTION
•Select the NFB according to the inverter power supply capacity.
•Install one NFB per inverter.

must conform to the requirements of national and local safety regulations and
electrical codes. (JIS, NEC section 250, IEC 536 class 1 and other applicable
standards)
•When the breaker is installed on the secondary side of the inverter, it may be
unnecessarily operated by harmonics if the effective value is less than the

1.2.6Power-off and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter's input side, it is recommended to provide an MC for the following
purposes. (Refer to page 10 for selection)
1) To release the inverter from the power supply when the inverter protective function
is activated or the drive becomes faulty (e.g. emergency stop operation)
2) To prevent any accident due to an automatic restart at restoration of power after an
inverter stop made by a power failure
3) To rest the inverter for an extended period of time
The control power supply for inverter is always running and consumes a little power.
When stopping the inverter for an extended period of time, powering off the inverter
will save power slightly.
4) To separate the inverter from the power supply to ensure safe maintenance and
inspection work
The inverter's input side MC is used for the above purpose, select class JEM1038AC3 for the inverter input side current when making an emergency stop during
normal operation.
REMARKS
The MC may be switched on/off to start/stop the inverter. However, since repeated inrush
currents at power on will shorten the life of the converter circuit (switching life is about 100,000
times), frequent starts and stops must be avoided. Turn on/off the inverter start controlling
terminals (STF, STR) to run/stop the inverter.
As shown on the right,
always use the start signal
(ON or OFF across
terminals STF or STR-SD)
to make a start or stop.

When the inverter is installed near a large-capacity power transformer (500kVA or
more with the wiring length of 10m (32.81feet) or less) or the power capacitor is to be
switched, an excessive peak current will flow in the power supply input circuit,
damaging the converter circuit. In such a case, always install the power factor

1.2.8Regarding noise and the installation of a noise filter
Some noise enters the inverter causing it to malfunction and others are generated by
the inverter causing the malfunction of peripheral devices. Though the inverter is
designed to be insusceptible to noise, it handles low-level signals, so it requires the
following general countermeasures to be taken.
(1) General countermeasures
• Do not run the power cables (I/O cables) and signal cables of the inverter in parallel
with each other and do not bundle them.
• Use twisted shield cables for the detector connecting and control signal cables and
connect the sheathes of the shield cables to terminal SD.
• Ground the inverter, motor, etc. at one point.
• Capacitances exist between the inverter's I/O wiring, other cables, ground and
motor, through which leakage currents flow to cause the earth leakage circuit
breaker, ground leakage relay and external thermal relay to operate unnecessarily.
To prevent this, take appropriate measures, e.g. set the carrier frequency in Pr. 72 to
a low value, use a ground leakage circuit breaker designed for suppression of
harmonics and surges, and use the electronic thermal relay function built in the
inverter.
• The input and output of the inverter main circuit include high-degree harmonics,
which may disturb communication devices (AM radios) and sensors used near the
inverter. In this case, install a FR-BIF(-H) optional radio noise filter (for use on the
input side only) or FR-BSF01 line noise filter to minimize interference.

1.2.9Grounding precautions
Leakage currents flow in the inverter. To prevent an electric shock, the inverter and
motor must be grounded. Grounding must conform to the requirements of national
and local safety regulations and electrical codes.
(JIS, NEC section 250, IEC 536 class 1 and other applicable standards)
Use the dedicated ground terminal to ground the inverter. (Do not use the screw in
the casing, chassis, etc.)
Use a tinned* crimping terminal to connect the ground cable. When tightening the
screw, be careful not to damage the threads.
*Plating should not include zinc.
Use the thickest possible ground cable. Use the cable whose size is equal to or
greater than that indicated in the following table, and minimize the cable length.
The grounding point should be as near as possible to the inverter.

CAUTION
The power factor improving capacitor and surge suppressor on the inverter
output side may be overheated or damaged by the harmonic components of the
inverter output. Also, since an excessive current flows in the inverter to activate
overcurrent protection, do not provide a capacitor and surge suppressor on the
inverter output side when the motor is driven by the inverter. To improve the
power factor, insert a power factor improving reactor on the inverter's primary
side or DC circuit. For full information, refer to page 17.

1.2.11Inverter-driven 400V class motor
In the PWM type inverter, a surge voltage attributable to wiring constants is generated
at the motor terminals. Especially for a 400V class motor, the surge voltage may
deteriorate the insulation. When the 400V class motor is driven by the inverter,
consider the following measures:
•Measures
It is recommended to take either of the following measures:
(1) Rectifying the motor insulation
For the 400V class motor, use an insulation-enhanced motor. Specifically
1) Specify the "400V class inverter-driven, insulation-enhanced motor".
2) For the dedicated motor such as the constant-torque motor and low-vibration
motor, use the "inverter-driven, dedicated motor".
(2) Suppressing the surge voltage on the inverter side
On the secondary side of the inverter, connect the optional surge voltage
suppression filter (FR-ASF-H).

CAUTION
•Make sure that the front cover is installed securely.
•The front cover is fitted with the capacity plate and the inverter unit with the
rating plate. Since these plates have the same serial numbers, always replace
the removed cover onto the original inverter.
•The sink-source logic change-over jumper connector must be fitted in only
one of those positions. If it is fitted in both positions at the same time, the
inverter may be damaged.

To start and stop the motor, first switch on the input power supply of the inverter

2-5 or by setting the required
values in Pr. 4 to Pr. 6 "multispeed setting" (high, middle, low
speeds). (For multi-speed

operation, refer to page 29.)
3) After the start signal has been input, the inverter starts operating when the
frequency setting signal reaches or exceeds the "starting frequency" set in Pr. 13
(factory-set to 0.5Hz).
If the motor load torque is large or the "torque boost" set in Pr. 0 is small, operation
may not be started due to insufficient torque until the inverter output frequency
reaches about 3 to 6Hz.
If the "minimum frequency" set in Pr. 2 (factory setting = 0Hz) is 6Hz, for example,
merely entering the start signal causes the running frequency to reach the
minimum frequency of 6Hz according to the "acceleration time" set in Pr. 7.
4) To stop the motor, operate the DC injection brake for the period of "DC injection
brake operation time" set in Pr. 11 (factory setting = 0.5s) at not more than the DC
injection brake operation frequency or at not more than 0.5Hz.
To disable the DC injection brake function, set 0 in either of Pr. 11 "DC injection
brake operation time" or Pr. 12 "DC injection brake voltage".
In this case, the motor is coasted to a stop at not more than the frequency set in
Pr. 10 "DC injection brake operation frequency" (0 to 120Hz variable) or at not
more than 0.5Hz (when the DC injection brake is not operated).
5) If the reverse rotation signal is input during forward rotation or the forward rotation
signal is input during reverse rotation, the inverter is decelerated and then
switched to the opposite output without going through the stop mode.

(Note) Assign the stop signal to any of
Pr. 60 to Pr. 62 (input terminal

2) If the start signal terminals STF (STR)SD are shorted once, then opened, the
start signal is kept on and starts the

short the start signals STR (STF)-SD
once, then open it.

output frequency meter (10, 2, 5, 4, AU)
The analog frequency setting input signals that may be entered are voltage and
current signals.
For the relationships between the frequency setting input voltages (currents) and
output frequencies, refer to the following diagram. The frequency setting input signals
are proportional to the output frequencies. Note that when the input signal is less than
the starting frequency, the output frequency of the inverter is 0Hz.
If the input signal of 5VDC (or 10V, 20mA) or higher is entered, the output frequency
does not exceed the maximum output frequency.

(1) Voltage input (10, 2, 5)
Enter the frequency setting input signal of 0 to 5VDC (or 0 to 10VDC) across the
frequency setting input terminals 2-5. The maximum output frequency is reached
when 5V (10V) is input across terminals 2-5.
The power supply used may either be the inverter's built-in power supply or an external
power supply. For the built-in power supply, terminals 10-5 provide 5VDC output.
For operation at 0 to 5VDC, set "0" in
Pr. 73 to the 0 to 5VDC input. Use
terminal 10 for the built-in power

1.4.4Indicator connection and adjustment (AM)
A full-scale 5VDC analog signal can
be output from across terminals AM-

The analog output level can be
calibrated by the operation panel or
parameter unit (FR-PU04). Terminal
AM function selection can be set in
Pr. 54 "AM terminal function
selection".
Terminal AM is isolated from the
control circuit of the inverter. The
cable length should not exceed
30m.
The output signal from terminal AM
delays about several 100ms in
output and therefore cannot be used
as a signal for control which requires
fast response.

1.4.5Control circuit common terminals (SD, 5, SE)
Terminals SD, 5, and SE are all common terminals (0V) for I/O signals and are isolated
from each other.
Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM,
RL).
Terminal 5 is a common terminal for the frequency setting analog input signals and
indicator terminal "AM". It should be protected from external noise using a shielded or
twisted cable.
Terminal SE is a common terminal for the open collector output terminal (RUN).

1.5.8Reset signal: Pr. 60 to Pr. 63 setting "10"
Used to reset the alarm stop state established when the inverter's protective function
is activated. The reset signal immediately sets the control circuit to the initial (cold)
status, e.g. initializes the electronic thermal relay function protection circuit. It shuts off
the inverter output at the same time. During reset, the inverter output is kept shut off.
To give this reset input, short terminals RES-SD for more than 0.1s. When the shorting
time is long, the operation panel or parameter unit displays the initial screen, which is
not a fault.
After opening terminals RES-SD (about 1s), operation is enabled.
The reset terminal is used to reset the inverter alarm stop state. If the reset terminal is
shorted, then opened while the inverter is running, the motor may be restarted during
coasting (refer to the timing chart below) and the output may be shut off due to
overcurrent or overvoltage.
Setting either "1" or "15" in reset selection Pr. 75 allows the accidental input of the
reset signal during operation to be ignored.

with. Fully check the terminal numbers of the computer since they change with the model.
*2. The inverters may be affected by reflection depending on the transmission speed or
transmission distance. If this reflection hinders communication, provide a terminating
resistor. When the RS-485 connector is used for connection, a terminating resistor cannot
be fitted, so use a distributor. Connect the terminating resistor to only the inverter remotest
from the computer. (Terminating resistor: 100
Ω)

1.8Design information
1) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for
commercial power supply-inverter switchover.
When the wiring is incorrect or if there is a commercial power supply-inverter
switch-over circuit as shown below, the inverter will be damaged by leakage current
from the power supply due to arcs generated at the time of switchover or chattering
caused by a sequence error.
2) If the machine must not be restarted when power is restored after a power failure,
provide a magnetic contactor in the inverter's primary circuit and also make up a
sequence which will not switch on the start signal.
If the start signal (start switch) remains on after a power failure, the inverter will
automatically restart as soon as the power is restored.
3) Since the input signals to the control circuit are on a low level, use two or more
parallel micro signal contacts or a twin contact for contact inputs to prevent a
contact fault.
4) Do not apply a large voltage to the contact input terminals (e.g. STF) of the control
circuit.
5) Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp
etc.
6) Make sure that the specifications and rating match the system requirements.

2. FUNCTIONS
This chapter explains the "functions" for use of this product. For simple
variable-speed operation of the inverter, the factory settings of the
parameters may be used as they are. Set the necessary parameters to
meet the load and operational specifications. Refer to the instruction
manual (basic) for the operation procedures. Always read the
instructions before using the functions.

CAUTION
As the contact input terminals RL, RM, RH, STR, open collector
output terminal RUN and contact output terminals A, B, C can be
changed in functions by parameter setting, their signal names
used for the corresponding functions are used in this chapter
(with the exception of the wiring examples). Note that they are
not terminal names.
REMARKS
Parameter copy
Use of the parameter unit (FR-PU04) allows the parameter values to
be copied to another FR-S500 series inverter. After batch-reading the
parameters of the copy source inverter, you can connect the
parameter unit to the copy destination inverter and batch-write the
parameters.
For the operation procedure, refer to the instruction manual of the
parameter unit (FR-PU04).

<Setting>
•In Pr. 3 and Pr. 47, set the base frequency (motor's rated frequency).
Use the RT signal to switch between these two different base frequencies.
(Turn on the RT signal to make Pr. 47 valid.) (*)
When running the standard motor, generally set the "base frequency" to the rated
frequency of the motor. When running the motor using commercial power supplyinverter switch-over operation, set the base frequency to the same value as the
power supply frequency.
If only "50Hz" is given on the motor rating plate as the frequency, always set the
"base frequency" to "50Hz". If it remains at "60Hz", the voltage may become too low
and torque shortage occurs, resulting in an overload trip. Special care must be taken
when "1" is set in Pr. 14 "load pattern selection".
•Set the base voltage (e.g. rated voltage of motor) in Pr. 19.
CAUTION
1. Set 60Hz in Pr. 3 "base frequency" when using a Mitsubishi constant-torque
motor.
2. When automatic torque boost is selected, Pr. 47 is invalid. When automatic
torque boost is selected, setting "- - -" or "888" in Pr. 19 uses the rated
output voltage.

1. The multi-speed settings override the main speeds (across terminals 2-5, 45, setting dial). When the multi-speed settings and setting dial are used in
the combined operation mode (Pr. 79=3), the multi-speed settings have
precedence.
2. The multi-speeds can also be set in the PU or external operation mode.
3. For 3-speed setting, if two or three speeds are simultaneously selected,
priority is given to the set frequency of the lower signal.
4. Pr. 24 to Pr. 27 and Pr. 80 to Pr. 87 settings have no priority between them.
5. The parameter values can be changed during operation.
6. When using this function with the jog signal, the jog signal has precedence.

<Setting>
•Use Pr. 7 and Pr. 44 to set the acceleration time required to reach the frequency set
in Pr. 20 from 0Hz.
•Use Pr. 8 and Pr. 45 to set the deceleration time required to reach 0Hz from the
frequency set in Pr. 20.
•Pr. 44 and Pr. 45 are valid when the RT signal is on. (When the RT signal is on, the
other second functions (Pr. 44, Pr. 45, Pr. 46, Pr. 47, additional parameter H7) are
also selected.)
•Set "- - -" in Pr. 45 to make the deceleration time equal to the acceleration time (Pr. 44).
CAUTION
1. In S-shaped acceleration/deceleration pattern A (refer to page 79), the set
time is the period required to reach the base frequency set in Pr. 3.

(Pr. 21 )
You can make setting to prevent stall caused by overcurrent and/or to prevent the
inverter from resulting in an overcurrent trip (to disable high-response current
restriction that limits the current) when an excessive current flows due to sudden
load fluctuation or ON-OFF on the output side of a running inverter.
• Stall prevention
If the current exceeds the stall prevention operation level (Pr.22), the output
frequency of the inverter is automatically varied to reduce the current.
• High response current limit
If the current exceeds the limit value, the output of the inverter is shut off to
prevent an overcurrent.

Explanation of functions (parameters)
CAUTION
•If the load is heavy, the lift is predetermined, or the acceleration/deceleration
time is short, the stall prevention may be activated and the motor not stopped
in the preset acceleration/deceleration time. Therefore, set optimum values to
the Pr. 21 and stall prevention operation level.
•When the high response current limit has been set in Pr. 21 (factory setting),
torque will not be provided at the Pr. 22 setting of 170% or higher. At this time,
make setting so that the high response current limit is not activated.
•In vertical lift applications, make setting so that the high response current
limit is not activated. Torque may not be produced, causing a drop due to
gravity.
CAUTION
Always perform test operation.
Stall prevention operation performed during acceleration may increase the
acceleration time.
Stall prevention operation performed during constant speed may cause
sudden speed changes.
Stall prevention operation performed during deceleration may increase the
deceleration time, increasing the deceleration distance.

2.3.13Stall prevention (Pr. 22 , Pr. 23 , Pr. 28 )
Set the output current level (% value to the inverter rated current) at which the
output frequency will be adjusted to prevent the inverter from stopping due to
overcurrent etc.
During high-speed operation above the rated motor frequency, acceleration
may not be made because the motor current does not increase. To improve
the operating characteristics of the motor in this case, the stall prevention
level can be reduced in the high frequency region. This function is effective for
performing operation up to the high speed range on a centrifugal separator
etc. Normally, set 60Hz in Pr. 28 "stall prevention operation reduction starting

REMARKS
When the high response current limit is set in Pr. 21 "stall prevention function selection"
(factory setting), do not set any value above 170% in Pr. 22. The torque will not be developed
by doing so.
If the Pr. 22 value is set to higher than 170%, make setting in Pr. 21 to disable the high
response current limit.
In vertical lift applications, make setting so the high response current limit is not activated.
Torque may not be produced, causing a drop due to gravity.
CAUTION
Do not set a small value as the stall prevention operation current. Otherwise,
torque generated will reduce.
Test operation must be performed.
Stall prevention operation during acceleration may increase the acceleration
time.
Stall prevention operation during constant speed may change the speed
suddenly.
Stall prevention operation during deceleration may increase the deceleration
time, increasing the deceleration distance.

When the speed is set in Pr. 37 (Pr. 37 ≠ 0), the speed is monitored and displayed in the
monitor/frequency setting mode.
At this time, setting can be made in the minimum setting (display) increments of 0.01r/min.
Due to the limitations on the resolution of the set frequency, the indication in the second
decimal place may differ from the setting.
CAUTION
Make sure that the running speed setting is correct.
Otherwise, the motor might run at extremely high speed, damaging the
machine.

Explanation of functions (parameters)
2.3.18Biases and gains of the frequency setting voltage (current)
(Pr. 38 , Pr. 39 , C2 to C7 )
You can set the magnitude (slope) of the output frequency as desired in relation
to the external frequency setting signal (0 to 5V, 0 to 10V or 4 to 20mADC).
The "bias" and "gain" functions are used to adjust the relationship between the
input signal entered from outside the inverter to set the output frequency, e.g. 0
to 5V, 0 to 10V or 4 to 20mADC, and the output frequency.
