Power Quality
Power quality is an issue of increasing significance. Yaskawa
Drives up to 25 HP are available with optional 3% or 5%
equivalent line impedance DC Bus Reactors. These optional DC
Bus Reactors can reduce the total harmonic distortion.
At 30 HP and above, Yaskawa Drives include 3% line impedance
as standard as well as a dual diode bridge rectifier which can be
configured to accept 12-pulse (delta-delta and delta-wye
secondary) transformer input. These transformers can be installed
at our factory as an integral part of the drive package or
purchased as a loose item, to eliminate power quality issues.
Yaskawa Drives can also be factory configured with an integral
18-pulse transformer. These packages are typically used to meet
the most strict harmonic requirements at both drive input
terminals and the point of common coupling.
The data listed below was collected on a 75 HP, 480V drive and
shows the different effects bus reactors, 12-pulse, and 18-pulse
harmonic mitigation solutions have at the input terminals to the
drive.
Easy To Use
Yaskawa Drives are factory-programmed and ready to run. For
operational simplicity and clarity, the LCD operator in the F7, G7,
P7 and V1000 drives has 5 lines x 16 characters. This display can
be set to several international languages. The keypad is intuitive
and includes parameter copying to move a chosen set of
parameters from one drive to another. Parameters are grouped in
two sets; Quick Start and Advanced. The USB Copy Unit allows
the J1000 or V1000 drives to connect to the USB port on a PC. It
can read, copy, and verify drive parameters from one drive to
another like drive.

G7 Three-Level Inverter
The 480V rated G7 drive, with its 3-level power section, can solve
major installation and reliability problems found in today's
industrial plants including:
Motor winding failures caused by high surge voltages in long
cable lengths between the motor and drive.
Motor bearing failures caused by bearing currents (shaft
voltage).
Instrument and measurement malfunction caused by
common mode current (noise).
The 3-level inverter has a circuit configuration consisting of 12
IGBTs (instead of 6) that facilitates access to the DC bus mid
point. This topology is referred to as a neutral point clamped
architecture. This configuration has three DC bus levels compared
to two in a conventional PWM drive.
2-Level Inverter3-Level Inverter
Measurements made comparing the G7 to a
conventional inverter confirm that the peak
voltage seen in long motor cables is reduced by
up to 33%. Bearing currents and common mode
currents are reduced by over 50%, which leads
to a four times increase in motor bearing life.
Thirteen patents were
awarded to Yaskawa
relative to this
technology. Although
the topology has been
seen in large medium

voltage inverters,
Yaskawa is the first to
offer it at 480V and
across the entire integral
horsepower range.
After 5000 hours of motor operation, bearing
vibration and wear are still normal with 3-level
inverter output, extending bearing life to 4 times
that of 2-level inverter operation.
Auto-tuning
The V1000, P7, F7 and G7 drives support several methods of
Auto-tuning. Auto-tuning is the process in which, after the user
enters basic motor nameplate data, the drive analyzes the motor
and calculates several key parameter settings needed for
maximum performance. This allows the drive to be used with
virtually any motor without complicated setup. The 3 Auto-tuning
methods are explained below.

and Line-to-Line Output Voltage Waveforms
The result is an output waveform that is more sinusoidal and that
switches in steps of 325VDC instead of 650VDC. The reduced
output voltage step significantly reduces the surge (peak) voltage
seen at the motor and the common mode voltage produced by
the inverter. Common mode voltage is the cause of bearing
currents and common mode noise.

Resistance Auto-tune
The motor's primary (or stator) resistance is important for several
functions including vector control, DC injection braking, high-slip
braking, speed search and torque compensation. The resistance
Auto-tuning method is primarily used in V/f control where a more
rigorous tune is not needed. The motor does not rotate.
Stationary Auto-tune
This method is designed primarily for use when the motor cannot
be uncoupled from the load or machine. This method should give
satisfactory results for most applications in all control methods.
The motor does not rotate.

Rotational Auto-tune
This is the preferred method for vector control performance and
will yield the best data for all control modes. The motor must be
uncoupled from the load for proper results. The motor will rotate
with this method. The rotational Auto-tuning method must be used
in the following cases: operation above the motor's rated speed,
torque control, and the Open Loop Vector 2 control method in the
G7 drive.
High Slip Braking (HSB)
The High Slip Braking function dissipates regenerative
deceleration energy in the motor by creating a large slip condition.
This function is ideal for high inertia rotating loads such as
centrifuges, presses, and blowers; and requires no braking
resistor. Braking times can be achieved that are approximately
50% less than the time required to decelerate a load normally.
The exact stopping time, however, is machine and
load inertia dependent. HSB has the following
application considerations:
HSB functions during motor stopping, not during
normal deceleration by reduced frequency reference.
HSB is not available for continuous regenerative loads such
as elevators, winders, or test stands. HSB is not suitable for
positioning applications such as transfer machines.
HSB can only be used in V/f control or V/f control w/ PG.
Custom Software
Custom software, sometimes referred to as CASE software,
replaces the drive's standard software and adds new functionality
or enhances existing standard functions. CASE (Custom
Application Software Environment) allows for easy customization
by Yaskawa engineers to solve difficult applications
and eliminate peripheral equipment. For example,
within F7 CASE, the following additional items
can be enabled: 30 custom parameters, 8 digital
input functions, 3 digital output functions, 2
analog input functions, 10 analog output functions,
Existing titles include 1000Hz High Frequency, 1500Hz High
Frequency, Electronic Lineshaft, Spindle Orientation, Enhanced
PID, Motion Control, and many others. CASE software is
available for the F7, G7, P7, V1000 and V74X drives.
