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 for the drive determines the starting and accelerating characteristics of the motor. Expect lower torque
than when running from line power. To get more starting torque, use a larger drive or increase both the motor and drive capacity.
Emergency Stop
When the drive faults out, the output shuts off but the motor does not stop immediately. A mechanical brake may be required
when it is necessary to stop the motor faster than the ability of the Fast Stop function of the drive.
Options
NOTICE: The B1, B2, +1, +2, and +3 terminals are used to connect optional A1000-compatible devices only. Connecting non-Yaskawa-
approved devices to these terminals may damage the drive.
Repetitive Starting/Stopping
Laundry machines, punching presses, and other applications with frequent starts and stops often approach 150% of their rated
current values. Heat stress generated from repetitive high current will shorten the life span of the IGBTs.
Yaskawa recommends lowering the carrier frequency, particularly when audible noise is not a concern. It is beneficial to
reduce the load, increase the acceleration and deceleration times, or switch to a larger drive to 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.
n
Installation
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.
n
Settings
Motor Code
When using OLV/PM, set the proper motor code to parameter E5-01 before performing a trial run.
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.
DC Injection Braking
NOTICE: Excessive current during DC Injection Braking and excessive duration of DC Injection Braking can cause motor overheat.
i.2General Safety
16
YASKAWA ELECTRIC TOEP C710616 41C YASKAWA AC Drive - A1000 Quick Start Guide
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. Install one of the available braking options or increase the capacity of the
drive for faster acceleration and deceleration.
n
General 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.
NOTICE: Prevent Equipment Damage. Install a fuse and a GFCI in models CIMR-A
o
4A0930 and 4A1200. Failure to comply may result in
serious damage to the facilities if the drive is defective.
Magnetic Contactor Installation
WARNING! Fire Hazard. Shut off the drive with a magnetic contactor (MC) when a fault occurs in any external equipment such as braking
resistors. Failure to comply may cause resistor overheating, fire, and injury to personnel.
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! Electrical Shock Hazard. When a drive is running a PM motor, voltage continues to be generated at the motor terminals after
the drive is shut off while the motor coasts to stop. Take the precautions described below to prevent shock and injury:
∙ In applications where the machine can still rotate after the drive has fully stopped a load, install a switch to the drive output side to disconnect
the motor and the drive.
∙ Do not allow an external force to rotate the motor beyond the maximum allowable speed or to rotate the motor when the drive has been
shut off.
∙ Wait for at least the time specified on the warning label after opening the load switch on the output side before inspecting the drive or
performing any maintenance.
∙ Do not open and close the load switch while the motor is running.
∙ If the motor is coasting, make sure the power to the drive is turned on and the drive output has completely stopped before closing the load
switch.
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. Drive models CIMR-Ao2A0069 to 2A0415 and 4A0058 to
4A1200 require the use of use ring terminals for UL/cUL compliance. 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
n
Standard Induction Motors
Low-Speed Range
The cooling fan of a standard motor should 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. Reduce the load torque
as the motor slows to prevent motor damage from overheat. Figure i.2 shows the allowable load characteristics for a Yaskawa
standard motor. Use a motor designed specifically for operation with a drive when 100% continuous torque is needed at low
speeds.

Figure i.2Allowable Load Characteristics for a Yaskawa Motor
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.
•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, install shock-absorbing rubber around the base of the motor and enable the Jump frequency
selection to prevent continuous operation in the resonant frequency range.
•Mechanical resonance can occur with long motor shafts and in applications such as turbines, blowers, and fans with high
inertia loads. Use Closed Loop Vector Control when these applications experience mechanical resonance problems.
Audible Noise
Noise created during run varies by the carrier frequency setting. When using a high carrier frequency, audible noise from the
motor is comparable to the motor noise generated when running from line power. Operating above the rated motor speed can
create unpleasant motor noise.
n
Synchronous Motors
•Contact Yaskawa or a Yaskawa agent when planning to use a synchronous motor not endorsed by Yaskawa.
•Use a standard induction motor when running multiple synchronous motors simultaneously. A single drive does not have
this capability.
•A synchronous motor may rotate slightly in the opposite direction of the Run command at start depending on parameter
settings and rotor position.
i.2General Safety
18
YASKAWA ELECTRIC TOEP C710616 41C YASKAWA AC Drive - A1000 Quick Start Guide
•The amount of generated starting torque differs depending on the control mode and motor type. Set up the motor with the
drive after verifying the starting torque, allowable load characteristics, impact load tolerance, and speed control range.
Contact Yaskawa or a Yaskawa agent when planning to use a motor that does not fall within these specifications:
•In Open Loop Vector Control for PM motors, braking torque is less than 125% when running between 20% and 100% speed,
even with a braking resistor. Braking torque drops to less than 50% when running at less than 20% speed.
•In Open Loop Vector Control for PM motors, the allowable load inertia moment is approximately 50 times higher than the
motor inertia moment.
Contact Yaskawa or a Yaskawa agent for questions concerning applications with a larger inertia moment.
•When using a holding brake in Open Loop Vector Control for PM motors, release the brake prior to starting the motor.
Failure to set the proper timing can cause speed loss.
•To restart a coasting motor rotating over 200 Hz while in V/f Control, first use the Short Circuit Braking function to bring
the motor to a stop. Short Circuit Braking requires a special braking resistor. Contact Yaskawa or a Yaskawa agent for
details.
•To restart a coasting motor rotating below 200 Hz, use the Speed Search function if the motor cable is not too long. If the
motor cable is relatively long, stop the motor using Short Circuit Braking.
n
Specialized Motors
Multi-Pole Motor
The rated current of a multi-pole motor differs from that of a standard motor, so be sure to check the maximum current when
selecting a drive. Always stop the motor before switching between the number of motor poles. The motor will coast to stop if
a regen overvoltage (ov) fault occurs or if overcurrent (oC) protection is triggered.
Submersible Motor
The rated current of a submersible motor is greater than that of a standard motor, so select the drive capacity 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.
When attaching an encoder to an explosion-proof motor, make sure the encoder is also explosion-proof. Use an insulating
signal converter to connect the encoder signal lines to the speed feedback option card.
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.
Motor with Brake
Take caution when using the drive to operate a motor with a built-in holding brake. If the brake is connected to the output side
of the drive, it may not release at start due to low voltage levels, so be sure to install a separate power supply for the motor
brake. Note that motors with built-in brakes tend to generate a fair amount of noise when running at low speeds.
n
Notes 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 on 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.
