General Application Precautions

n

Selection
Installing a Reactor

Use an AC reactor or DC link choke in the following situations:

• to suppress harmonic current.

• to smooth peak current that results from capacitor switching.

• when the power supply is above 600 kVA.

• when the drive is running from a power supply system with thyristor converters.

60 400

For specialized motors, make sure that the motor rated current is less than the rated output current for the drive.

When running more than one motor in parallel from a single drive, the capacity of the drive should be larger than [total motor
rated current × 1.1].

Starting Torque

The overload rating of the drive determines the starting and accelerating characteristics of the motor. Expect lower running
torque than when running the motor from line power. To get more starting torque, use a larger drive or increase both the motor
and drive capacity.

Emergency/Fast Stop

During a drive fault condition, a protective circuit is activated and drive output is shut off. The motor may coast to a stop or
attempt to decelerate depending on parameter settings. If the emergency/fast stop cannot stop the load as fast as desired, a
customer-supplied mechanical brake may be required. Test emergency stop circuitry before putting drive into operation.

Repetitive Starting/Stopping

n

Applications with frequent starts and stops often exceed 150% of their rated current values. Heat stress generated from
repetitive high current can shorten the life span of the IGBTs. The expected lifetime for the IGBTs is about 8 million start and
stop cycles with a 4 kHz carrier frequency and a 150% peak current.

YASKAWA TOEP YAIQPM 02B YASKAWA AC Drive - iQpump Micro Quick Start Guide

33

i.1 Preface

Yaskawa recommends lowering the carrier frequency, particularly when audible noise is not a concern. The user can also
choose to reduce the load, increase the acceleration and deceleration times, or switch to a larger drive. This will help keep
peak current levels under 150%. Be sure to check the peak current levels when starting and stopping repeatedly during the
initial test run, and make adjustments accordingly.

Installation

n

Enclosure Panels

Keep the drive in a clean environment by installing the drive in an enclosure panel or selecting an installation area free of
airborne dust, lint, and oil mist. Be sure to leave the required space between drives to provide for cooling, and take proper
measures so the ambient temperature remains within allowable limits and keep flammable materials away from the drive.
Yaskawa offers protective designs for drives that must be used in areas subjected to oil mist and excessive vibration. Contact
Yaskawa or your Yaskawa agent for details.

Installation Direction

NOTICE: Install the drive upright as specified in the manual. Refer to Mechanical Installation on page 39 for more information on

installation. Failure to comply may damage the drive due to improper cooling.

Settings

n

Upper Limits

NOTICE: The drive is capable of running the motor up to 400 Hz. Be sure to set the upper limit for the frequency of the drive to prevent the

possible danger of accidentally operating equipment at higher than rated speed. The default setting for the maximum output frequency is
60 Hz.

Lower Limits

NOTICE: Many pumps have a minimum safe operating speed. Be sure to properly set the minimum pump speed in to protect the pump

from damage.

DC Injection Braking

NOTICE: Excessive current during DC Injection Braking and excessive duration of DC Injection Braking can cause motor overheat.

Acceleration/Deceleration Times

Acceleration and deceleration times are affected by the amount of torque generated by the motor, the load torque, and the
inertia moment. Set a longer accel/decel time when Stall Prevention is enabled. The accel/decel times are lengthened for as
long as the Stall Prevention function is in operation.

General Handling

n

Wiring Check

NOTICE: Do not connect power supply lines to output terminals U/T1, V/T2, or W/T3. Failure to comply will destroy the drive. Be sure to

perform a final check of all sequence wiring and other connections before turning on the power and also check for short circuits on the
control terminals, which may damage the drive.

Selecting a Circuit Breaker or Circuit Interrupter

Yaskawa recommends installing a Ground Fault Circuit Interrupter (GFCI) to the power supply side. The GFCI should be
designed for use with AC drives (e.g., Type B according to IEC 60755).

Select a Molded Case Circuit Breaker (MCCB) or GFCI with a rated current 1.5 to 2 times higher than the drive rated input
current to avoid nuisance trips caused by harmonics in the drive input current.

Magnetic Contactor Installation

NOTICE: To get the full performance life out of the electrolytic capacitors and circuit relays, refrain from switching the drive power supply

off and on more than once every 30 minutes. Frequent use can damage the drive. Use the drive to stop and start the motor.

Inspection and Maintenance

WARNING! Electrical Shock Hazard. Capacitors in the drive do not immediately discharge after shutting off the power. Wait for at least the

amount of time specified on the drive before touching any components after shutting off the power. Failure to comply may cause injury to
personnel from electrical shock.

WARNING! Burn Hazard. Because the heatsink can get very hot during operation, take proper precautions to prevent burns. When replacing
the cooling fan, shut off the power and wait at least 15 minutes to be sure that the heatsink has cooled down. Failure to comply may cause
burn injury to personnel.

Wiring

Yaskawa recommends using ring terminals on all drive models. UL/cUL approval requires the use of UL Listed closed-loop
crimp terminals when wiring the drive main circuit terminals. Use only the tools recommended by the terminal manufacturer
for crimping.

Transporting the Drive

NOTICE: Never steam clean the drive. During transport, keep the drive from coming into contact with salts, fluorine, bromine, phthalate

ester, and other such harmful chemicals.

Motor Application Precautions

Standard Induction Motors

n

Low Speed Range

The cooling fan of a standard motor is usually designed to sufficiently cool the motor at the rated speed. As the self-cooling
capability of such a motor reduces with the speed, applying full torque at low speed will possibly damage the motor. To prevent
motor damage from overheat, reduce the load torque as the motor slows. Figure i.2 shows the allowable load characteristics
for a Yaskawa standard motor. A motor designed specifically for operation with a drive should be used when 100% continuous
torque is needed at low speeds.

Insulation Tolerance

NOTICE: Consider motor voltage tolerance levels and motor insulation in applications with an input voltage of over 440 V or particularly

long wiring distances.

High-Speed Operation

NOTICE: Problems may occur with the motor bearings and dynamic balance of the machine when operating a motor beyond its rated speed.

Contact the motor or machine manufacturer.

Torque Characteristics

Torque characteristics differ compared to operating the motor directly from line power. The user should have a full
understanding of the load torque characteristics for the application.

Vibration and Shock

The drive allows selection of high carrier PWM control and low carrier PWM. Selecting high carrier PWM can help reduce
motor oscillation (drive current derating may be required).

Take particular caution when adding a variable speed drive to an application running a motor from line power at a constant
speed. If resonance occurs, use shock absorbing mounts to the motor base and enable the Jump frequency selection to prevent
continuous operation in the resonant frequency range.

Audible Noise

The audible noise of the motor varies based on the carrier frequency setting. However, drive current derating may be required.
When using a high carrier frequency, audible noise from the motor is comparable to the motor noise generated when running
from line power.

Specialized Motors

n

Multi-Pole Motor

Because the rated current will differ from a standard motor, be sure to check the maximum current when selecting a drive.
Always stop the motor before switching between the number of motor poles. If a regen overvoltage (oV) fault occurs or if
overcurrent protection (oC) is triggered, the motor will coast to stop.

i.1 Preface

Submersible Motor

The rated current of a submersible motor is greater than that of a standard motor, so select the drive accordingly. Use a motor
cable large enough to avoid decreasing the maximum torque level from voltage drop caused by a long motor cable.

Explosion-Proof Motor

The motor and the drive must be tested together to be certified as explosion-proof. The drive is not designed for explosion­proof areas.

Geared Motor

Make sure that the gear and the lubricant are rated for the desired speed range to avoid gear damage when operating at low
speeds or very high speeds. Consult with the manufacturer for applications that require operation outside the rated speed range
of the motor or gear box.

Single-Phase Motor

Variable speed drives are not designed to operate with single phase motors. Using capacitors to start the motor causes excessive
current to flow and can damage drive components. A split-phase start or a repulsion start can burn out the starter coils because
the internal centrifugal switch is not activated. The drive is for use with three-phase motors only.

Notes on Power Transmission Machinery

n

Installing an AC drive in machinery that was previously connected directly to the power supply will allow the machine to
operate at variable speeds. Continuous operation outside of the rated speeds can wear out lubrication material in gear boxes
and other power transmission parts. Make sure that lubrication is sufficient within the entire speed range to avoid machine
damage. Note that operation above the rated speed can increase the noise generated by the machine.

the enclosure does not exceed the specified levels.
Do not allow ice to develop on the drive.

Install the drive in an area free from:

• oil mist and dust

• metal shavings, oil, water or other foreign materials

• radioactive materials

• combustible materials (e.g., wood)

• harmful gases and liquids

• excessive vibration

• chlorides

• direct sunlight
For IP66/NEMA Type 4X enclosure drives, install the drive in an environment suitable for IP66/NEMA Type 4X

enclosures:

• NEMA Type 4X – Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel
against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet,
snow, windblown dust, splashing water, hose-directed water, and corrosion; and that will be undamaged by the external
formation of ice on the enclosure.

• IP66 – Dust-tight enclosures to do not allow any dust to penetrate. The enclosure guards the drive against powerful
jetting water sprayed from any direction and is protected against access to hazardous parts with a wire.

NOTICE: Prevent foreign matter such as metal shavings or wire clippings from falling into the drive during installation and project
construction. Failure to comply could result in damage to the drive. Place a temporary cover over the top of the drive during installation.
Remove the temporary cover before startup, as the cover will reduce ventilation and cause the drive to overheat.

NOTICE: Avoid placing drive peripheral devices, transformers, or other electronics near the drive. Failure to comply could result in erroneous
operation. If such devices must be used in close proximity to the drive, take proper steps to shield the drive from noise.

i.4 Electrical Installation

<1> Remove the jumper when installing an optional DC link choke.

<2> The MC on the input side of the main circuit should open when the thermal relay is triggered.

<3> Self-cooled motors do not require separate cooling fan motor wiring.

<4> Connected using sequence input signal (S1 to S7) from NPN transistor; Default: sink mode (0 V com).

<5> Use only a +24 V internal power supply in sinking mode; the source mode requires an external power supply.

<6> Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters and wattmeters; they are not
intended for use as a feedback-type of signal.

<7> Disconnect the wire jumper between HC and H1 when utilizing the safety input. Refer to Wiring the Control Circuit

Terminal on page 52 for details on removing the jumper. The wire length for the Safe Disable input should not exceed

30 m.

<8> Note that if the drive is set to trigger a fault output whenever the fault restart function is activated (L5-02 = 1), then a
sequence to interrupt power when a fault occurs will result in shutting off the power to the drive as the drive attempts to restart
itself. The default setting for L5-02 is 0 (fault output active during restart attempt).

WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal parameter is
properly set (S5 for 3-Wire; H1-05 = “0”). Improper sequencing of run/stop circuitry could result in death or serious injury from moving
equipment.

WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before energizing
the drive. Failure to comply could result in death or serious injury from moving equipment. When programmed for 3-Wire control, a momentary
closure on terminal S1 may cause the drive to start.

WARNING! When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control terminals and ensure parameter
b1-17 is set to 0 (drive does not accept a run command at power up (default). If the drive is wired for 3-Wire sequence but set up for 2-Wire
sequence (default) and if parameter b1-17 is set to 1 (drive accepts a Run command at power up), the motor will rotate in reverse direction
at power up of the drive and may cause injury.

WARNING! When the application preset function is executed (or A1-06 is set to any value other than 0) the drive I/O terminal functions
change. This may cause unexpected operation and potential damage to equipment or injury.

Wire Gauges and Tightening Torques

Ground Grounding Terminal 49

Select the appropriate wires and crimp terminals from Table i.3 through Table i.5.

Note: 1. Wire gauge recommendations based on drive continuous current ratings using 75 °C 600 Vac vinyl-sheathed wire assuming ambient

temperature within 30 °C and wiring distance shorter than 100 m.

2. Terminals ⊕1, ⊕2, ⊖, B1 and B2 are for connecting optional devices such as a braking resistor. Do not connect other non-specified
devices to these terminals.

• Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop is greater
than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the following formula to
calculate the amount of voltage drop:

•

Line drop voltage (V) = 3 x wire resistance (Ω/km) x wire length (m) x current (A) x 10

-3

• Refer to instruction manual TOBP C720600 00 for braking unit or braking resistor unit wire gauges.

• Refer to UL Standards Compliance on page 102 for information on UL compliance.

This section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motor terminals.

NOTICE: When connecting the motor to the drive output terminals U/T1, V/T2, and W/T3, the phase order for the drive and motor should
match. Failure to comply with proper wiring practices may cause the motor to run in reverse if the phase order is backward.

NOTICE: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible interference related issues. Failure to
comply may result in abnormal operation of drive and nearby equipment.

NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Improper application of noise filters could
result in damage to the drive.

NOTICE: Do not connect the AC power line to the output motor terminals of the drive. Failure to comply could result in death or serious
injury by fire as a result of drive damage from line voltage application to output terminals.

Cable Length Between Drive and Motor

n

When the cable length between the drive and the motor is too long (especially at low frequency output), note that the cable
voltage drop may cause reduced motor torque. Drive output current will increase as the leakage current from the cable increases.
An increase in leakage current may trigger an overcurrent situation and weaken the accuracy of the current detection.

Adjust the drive carrier frequency according to the following table. If the motor wiring distance exceeds 100 m because of the
system configuration, reduce the ground currents.

Refer to Table i.6 to set the carrier frequency to an appropriate level.

Table i.6 Cable Length Between Drive and Motor

Cable Length 50 m or shorter 100 m or shorter Longer than 100 m

Carrier Frequency 15 kHz or less 5 kHz or less 2 kHz or less

Note: When setting carrier frequency, calculate the cable length as the total distance of wiring to all connected motors when running multiple

Ground Wiring

n

motors from a single drive.

Follow the precautions to wire the ground for one drive or a series of drives.

WARNING! Electrical Shock Hazard. Always use a ground wire that complies with technical standards on electrical equipment and minimize
the length of the ground wire. Improper equipment grounding may cause dangerous electrical potentials on equipment chassis, which could
result in death or serious injury.

WARNING! Electrical Shock Hazard. Be sure to ground the drive ground terminal. (200 V Class: Ground to 100 Ω or less, 400 V Class:
Ground to 10 Ω or less). Improper equipment grounding could result in death or serious injury by contacting ungrounded electrical equipment.

NOTICE: Do not share the ground wire with other devices such as welding machines or large-current electrical equipment. Improper
equipment grounding could result in drive or equipment malfunction due to electrical interference.

NOTICE: When using more than one drive, ground multiple drives according to instructions. Improper equipment grounding could result in
abnormal operation of drive or equipment.

Refer to Figure i.13 when using multiple drives. Do not loop the ground wire.

Control Circuit Terminal Block Functions

Drive parameters determine which functions apply to the multi-function digital inputs (S1 to S7), multi-function digital outputs
(MA, MB), multi-function pulse inputs and outputs (RP, MP) and multi-function photocoupler outputs (P1, P2). The default
is called out next to each terminal in Figure i.9.

WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after being wired. Operating a drive with
untested control circuits could result in death or serious injury.

WARNING! Confirm the drive I/O signals and external sequence before starting test run. Setting parameter A1-06 may change the I/O
terminal function automatically from the factory setting. Failure to comply may result in death or serious injury.

The main frequency reference can either be a voltage or current signal input. For voltage signals both analog inputs, A1 and
A2, can be used, for current signals A2 must be used.

When using input A2 as a voltage input, set DIP switch S1 to “V” (left position) and program parameter H3-09 to 0 (0 to +10
Vdc with lower limit) or 1 (0 to +10 Vdc without lower limit).

To use current input at terminal A2, set the DIP switch S1 to "I" (default setting) and set parameter H3-09 = 2 or 3 (4-20 mA
or 0-20 mA). Set parameter H3-10 = 0 (frequency reference).

on the digital operator will light and the STOP indicator will flash.

No. Parameter Name Setting Range Default

b1-01 Frequency Reference Selection 1 0 to 4 0

In order to run the drive and motor, the drive must receive a Run command and an Auto Setpoint command. Parameter b1-01
specifies the origin of the Auto setpoint when in AUTO Mode. Switch to AUTO mode by pressing the AUTO button on the
HOA keypad while the drive is stopped.

Note: If a Run command is input to the drive without a corresponding Auto setpoint, the Run indicator on the HOA keypad will turn on and the

STOP indicator on the keypad will blink.

If the drive should follow the “HAND Reference” set by the HOA keypad, use HAND Mode by pressing the HAND key and
set P5-01 to “1: Hand Reference (P5-02).” The HAND reference can then be entered into the U1-01 monitor parameter in the
“-DRIVE-” Menu.

The drive offers the ability to provide four types of “Auto Setpoint” reference sources. These Auto Setpoint reference sources
are determined by the setting of b1-01 and the drive set to AUTO Mode by pressing the AUTO key on the keypad.

Prior to programming, it is recommended to select the system units (P1-02) and the feedback device, Scaling (P1- 03) first.
P1-03 will automatically scale the drive setpoint.

Example: P1-02 = 1: PSI

P1-03 = 200, feedback range = 200 PSI.

If the drive should follow an “Auto Set-Point” set by the HOA keypad: Set b1-01 to “0: Operator” (factory default). The Auto
setpoint can then be entered into the U5-99 monitor parameter in the “-DRIVE-” menu.

Setting 0: Operator (HOA keypad)

Using this setting, the frequency reference can be input by:

•

switching between the multi-speed references in the d1-oo parameters.

• entering the frequency reference on the operator keypad.
This selection will also switch PID setpoint to Q1-01.

Setting 1: Terminals (Analog Input Terminals)

Using this setting, an analog frequency reference can be entered from:

• Terminal A1 using a 0 to 10 Vdc signal.

• Terminal A2 using either a 0 to 10 Vdc or a 0/4 to 20 mA signal.

Note: Terminal A2 supports voltage and current input. The input signal type must be set up by setting DIP switch S1 and adjusting parameter

H3-09.

Entering only the main frequency reference:

Using Control Circuit Terminal A1 (0 to 10 Vdc voltage input):

Use a circuit such as the one shown in Figure i.30 or an external 0 to 10 Vdc voltage source like a PLC analog output and set
the input level selection for A1 in parameter H3-02 as desired.

• Using Control Circuit Terminal A2 (0/4 to 20 mA current input)
Connect input A2 to an external current source such as the one shown in Figure i.31. Make sure that switch S1 is set to “I”

and set the appropriate signal level for terminal A2 by entering 2 (4 to 20 mA) or 3 (0 to 20 mA) into parameter H3-09. The
terminal A2 function must be set to frequency bias by entering 0 into parameter H3-10.

Figure i.31 Setting the Frequency Reference by Current Input

Switching between Main/Auxiliary Frequency References

The frequency reference input can be switched between terminal A1 (main) and terminal A2 (auxiliary). When using this
function:

• Make sure that b1-01 is set to “1” (Frequency reference from analog input).

• Set the terminal A2 function to auxiliary frequency (H3-10 = 2).

•

Set one digital input to multi-speed 1 (H1-oo = 3, default for S5).

The frequency reference value is read from

• Terminal A1 when the digital input set for multi-speed 1 is open.

• Terminal A2 when the digital input set for multi-speed 1 is closed.

Figure i.31 shows a wiring example for main/auxiliary reference switching using digital input S5.

Note: If an overcurrent (oC) fault occurs during DC Injection Braking to Stop, lengthen the minimum baseblock time (L2-03) until the fault no

longer occurs.

Setting 3: Coast to Stop with Timer (Used for Back Spin Control on Vertical Turbine Pumps)

When the Run command is removed, the drive coasts to a stop. If parameter b1-11 = 0, the coast-timer (Run Delay at Stop)
becomes a value determined by a combination of output frequency and C1-02. However, if b1-11 > 0, the Run Delay at Stop
timer is set to b1-11. If the Run command is reissued during the Run Delay at Stop timer time, the drive WILL restart when
the timer expires without the need to re-cycle the Run command. The Run Delay at Stop timer will operate for both AUTO
Mode and HAND Mode. The Run Delay at Stop timer will still operate when the drive goes to sleep and then wakes up. During
the Run Delay at Stop timer execution, the HOA keypad will display a Start Delay message.

Setting F: Not Used/Through Mode

Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function in
the drive. Setting F, however, still allows the input status of the terminal (open or closed) to be read out by a PLC via a
communication option or MEMOBUS/Modbus communications. The drive input terminals can then be used as remote I/O by
the PLC.

Setting 14: Fault Reset

When the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts to
stop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the Run
command, clear the fault either by pressing the RESET key on the digital operator or closing a digital input configured as a
Fault Reset (H1-oo = 14).

Note: Remove the Run command prior to resetting a fault. Fault Reset commands are ignored while the Run command is present.

Setting 20 to 2F: External Fault

The External fault command stops the drive when problems occur with external devices.

To use the External fault command, set one of the multi-function digital inputs to a value between 20 and 2F. The digital
operator will display EFo where o is the number of the terminal to which the external fault signal is assigned.

For example, if an external fault signal is input to terminal S3, “EF3” will be displayed.
Select the value to be set in H1-oo from a combination of any of the following three conditions:

• Signal input level from peripheral devices (N.O., N.C.)

• External fault detection method

• Operation after external fault detection
An “On-Delay” timer will be applied to the external fault if it is “Normally Open” and an “Off-Delay” timer will be applied

to the external fault if it is “Normally Closed”.

If the external fault is set to “During Run”, the time delay will start after the Run command is received.

Table i.22 shows the relationship between the conditions and the value set to H1-oo:

Terminal statuses, detection conditions, and stopping methods marked with an “O” are applicable to the corresponding settings.

Settings 40, 41: Forward Run, Reverse Run Command for 2-Wire Sequence

Configures the drive for a 2-Wire sequence.

When an input terminal set to 40 closes, the drive operates in the forward direction. When an input set for 41 closes, the drive
operates in reverse. Closing both inputs simultaneously will result in an external fault.

Note: 1. This function cannot be used simultaneously with settings 42 and 43.

2. The same functions are assigned to terminals S1 and S2 when the drive is initialized for 2-Wire sequence.

Figure i.40 Example Wiring Diagram for 2-Wire Sequence

Setting 80: HAND Mode

Closing this input will put the drive in HAND Mode.

If this contact is closed within one second of power-up, the drive will honor the utility delay time.

Note: When inputs 80 and 81 are closed simultaneously, input 80 has priority and P5-01 determines the frequency reference.

Setting 81: HAND Mode 2

Closing this input will put the drive in HAND Mode using P5-05 as a frequency reference.

If this contact is closed within one second of power-up, the drive will honor the utility delay time.

Note: When inputs 80 and 81 are closed simultaneously, input 80 has priority and P5-01 determines the frequency reference.

Settings 8D and 8E: Multi Setpoints 1 and 2

IP66/NEMA Type 4X enclosures:

• NEMA Type 4X – Enclosures constructed for either indoor or outdoor use to provide a
degree of protection to personnel against incidental contact with the enclosed equipment;
to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust,
splashing water, hose-directed water, and corrosion; and that will be undamaged by the
external formation of ice on the enclosure.

• IP66 – Dust-tight enclosures to not allow any dust to penetrate. The enclosure guards the
drive against powerful jetting water sprayed from any direction and is protected against
access to hazardous parts with a wire.

Single-Phase Derating

iQpump Micro drives are compatible for use with both three-phase and single-phase input power supplies. The drive output
to the motor is always three-phase, regardless of number of input phases.

Output capacity to the motor is derated when using single-phase input power and the drive firmware includes protection for
single-phase input applications. This protection is enabled by default. Disabling this protection for single-phase input
applications can void warranty and result in premature failure.

Selection of larger models always results in greater output capacity to the motor when supplying the drive with three-phase
input power. However, the selection of larger models does not always yield greater output capacity when using the drive with
single-phase input power.

Several factors affect the amount of derated drive output capacity when single-phase input power is supplied to the drive:

• Single-phase input voltage level

• Motor voltage rating

• Amount of input impedance.
The tables in this section assist in model selection by considering factors that affect the amount of derating in single-phase

input power applications.

Single-Phase Input Sizing

n

The rated output current listed in the tables allows for a 120% overload for 60 seconds. Contact Yaskawa if assistance is needed
in selecting drive models with higher overload requirements. Adding more impedance than is specified will degrade
performance.
