uGeneral Application Precautions
nSelection
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.

Figure i.1 Installing a Reactor
Drive Capacity
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.
nRepetitive Starting/Stopping
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 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.
nInstallation
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 28 for more information on
installation. Failure to comply may damage the drive due to improper cooling.
nSettings
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.
i.2 General Safety
16 YASKAWA TOEP YAIQPM 03B YASKAWA AC Drive - iQpump Micro User Manual

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.
nGeneral Handling
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.
uMotor Application Precautions
nStandard Induction Motors
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.
nSpecialized Motors
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.
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 explosion-
proof 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.
i.2 General Safety
18 YASKAWA TOEP YAIQPM 03B YASKAWA AC Drive - iQpump Micro User Manual

Single-Phase Motor
Variable speed drives are not designed to operate with single phase motors. Using capacitors to start the motor causes a high-
frequency current to flow to the capacitors and can damage the capacitors. 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.
nNotes on Power Transmission Machinery
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.
