uApplication Notes
nSelection
Installing a Reactor
An AC or DC reactor can be used for the following:
• 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.
Note: A DC reactor is built in to models CIMR-T2A0110 to 2A0415 and CIMR-T4A0058 to 4A0362.
Figure i.1
Figure i.1 Installing a Reactor
Drive Capacity
For specialized motors, make sure that the motor rated current is less than 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 1.1 times of
the total motor rated current.
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 is shut off. This, however, does not stop the motor immediately. Some type of
mechanical brake may be needed if it is necessary to halt the motor faster than the Fast Stop function is able to.
Options
The B1, B2, +1, +2, and +3 terminals are used to connect optional devices. Connect only T1000A-compatible devices.
nInstallation
Enclosure Panels
Keep the drive in a clean environment by either selecting an area free of airborne dust, lint, and oil mist, or install the
drive in an enclosure panel. Be sure to leave the required space between drives to provide for cooling, and that proper
measures are taken so that the ambient temperature remains within allowable limits. Keep flammable materials away
from the drive. If the drive must be used in an area where it is subjected to oil mist and excessive vibration, protective
designs are available. Contact Yaskawa or your Yaskawa agent for details.
Installation Direction
The drive should be installed upright as specified in the manual. For more information on installation, Refer to
Mechanical Installation on page 36.
nSettings
Upper Limits
The drive is capable of running the motor up to 400 Hz. Due to the danger of accidentally of operating at high speed, be
sure to set the upper limit for the frequency. The default setting for the maximum output frequency is 50 Hz.

DC Injection Braking
Motor overheat can result if there is too much current used during DC Injection Braking, or if the time for DC Injection
Braking is too long.
Acceleration/Deceleration Times
Acceleration and deceleration times are affected by how much torque the motor generates, 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 operating. For faster acceleration and deceleration, install one of the braking options
available or increase the capacity of the drive.
nGeneral Handling
Wiring Check
Never connect the power supply lines to output terminals U/T1, V/T2, or W/T3. Doing so will destroy the drive. Be sure
to perform a final check of all sequence wiring and other connections before turning the power on. Make sure there are
no short circuits on the control terminals (+V, AC, etc.), as this could damage the drive.
Selecting a Circuit Breaker or Leakage Circuit Breaker
Yaskawa recommends installing equipment for residual current monitoring/detection (RCM/RCD) to the power supply
side. The RCM/RCD should be designed for use with an AC drive (e.g. Type B according to IEC 60755).
Select a MCCB (Molded Case Circuit Breaker) or RCM/RCD with a rated current that is 1.5 to 2 times higher than the
rated current of the drive in order to avoid nuisance trips caused by harmonics in the drive input current. Also refer to
Installing a Molded Case Circuit Breaker (MCCB) on page 344.
Magnetic Contactor Installation
Use a magnetic contactor (MC) to ensure that power to the drive can be completely shut off when necessary. The MC
should be wired so that it opens when a fault output terminal is triggered.
Avoid switching a magnetic contactor on the power supply side more frequently than once every 30 minutes. Frequent
switching can cause damage to the drive.
Inspection and Maintenance
Capacitors in the drive take time to discharge even after the power has been shut off. After shutting off the power, wait
for at least the amount of time specified on the drive before touching any components.
The heatsink can become quite hot during operation, and proper precautions should be taken 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.
Even when the power has been shut off for a drive running a PM motor, voltage continues to be generated at the motor
terminals while the motor coasts to stop. Take the precautions described below to prevent shock and injury:
• In Applications where the machine can still rotate even though the drive has fully stopped a load switch for
disconnecting motor and drive should be installed to the output side of the drive.
• Do not allow an external force to rotate the motor beyond the maximum allowable speed, also 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, as this can damage the drive.
• 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.
Wiring
All wire ends should use ring terminals for UL/cUL compliance. Use only the tools recommended by the terminal
manufacturer for crimping.
Transporting the Drive
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.

uNotes on Motor Operation
nUsing a Standard Motor
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.
Insulation Tolerance
Consider voltage tolerance levels and insulation in applications with an input voltage of over 440 V or particularly long
wiring distances. Contact Yaskawa or your Yaskawa agent for consultation.
High Speed Operation
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
T1000A lets the user choose between high carrier PWM control and low carrier PWM. Selecting high carrier PWM can
help reduce motor oscillation.
Take particular caution when using a variable speed drive for an application that is conventionally run from line power at
a constant speed. If resonance occurs shock-absorbing rubber should be installed around the base of the motor.
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 r/min,
however, can create unpleasant motor noise.
nUsing a Synchronous Motor
• Contact Yaskawa or your Yaskawa agent if you plan to use any other synchronous motor not endorsed by Yaskawa.
• A single drive is not capable of running multiple synchronous motors at the same time. Use a standard induction motor
for such setups.
• At start, a synchronous motor may rotate slightly in the opposite direction of the Run command depending on
parameter settings and rotor position.
• The amount of starting torque that can be generated differs by each control mode and by the type of motor being used.
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 your Yaskawa agent if you plan 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% to 100%
speed, even with a braking resistor. Braking torque drops to less than half 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 or less. Contact Yaskawa or your Yaskawa agent 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 result in speed loss. Not for use with conveyor, transport, or hoist type applications.
• To restart a coasting motor rotating at over 200 Hz while in the V/f control mode, use the Short Circuit Braking
function to first bring the motor to a stop. Short Circuit Braking requires a special braking resistor. Contact Yaskawa or
your Yaskawa agent for details.
Speed Search can be used to restart a coasting motor rotating slower than 200 Hz. If the motor cable is relatively long,
however, the motor should instead be stopped using Short Circuit Braking, which forces the motor to stop by creating a
short-circuit in the motor windings.
