Yaskawa Culture & Methodology
Yaskawa was founded in this country in 1915.
What is Japan?
Yaskawa spec sheets indicate this stop mode cuts motor torque without removing 3-phase power.
What is Safe Torque Off (STO)?
This fundamental law relates voltage, current, and resistance in a linear circuit.
What is Ohm's Law?
This equation expresses Newton's Second Law of Motion, relating force, mass, and acceleration.
What is F= ma?
In the VFD Basics episode of Yaskawa's podcast, VFD Vibes, Greg says this three-part structure makes up the core of any VFD: rectifier, DC bus, and this.
What is an inverter?
Yaskawa's global headquarters is located in this southern Japanese prefecture—also famous for ramen and hot springs.
What is Fukuoka?
GA800 (IP20) can operate at this max ambient temperature without derating.
What is 50 degrees Celsius?
This extremely small unit of capacitance is commonly used in high-frequency circuits and equals one trillionth of a farad.
What is a picofarad?
This unit is defined as one newton per square meter.
What is a pascal?
In the Don’t Short Me episode of Yaskawa's Podcast, VFD Vibes, Greg and Steve Perreault caution us to always verify this drive panel protection rating.
What is SCCR (Short Circuit Current Rating)
This Japanese philosophy, meaning "continuous improvement", drives daily process refinement.
What is Kaizen?
This type of inverter control provides more precise low-speed torque performance than basic V/f control.
What is vector control?
The resistance of this perfect theoretical material is exactly zero, but only when cooled below a critical temperature.
What is a superconductor?
This process involves gradually cooling a metal to relieve internal stresses.
In the AHR Expo Experience episode of Yaskawa's podcast VFD Vibes, the HV600’s redundancy feature uses two contactors — one for the drive and one for this mode.
What is bypass mode?
Also known as error-proofing, this Japanese methodology prevents defects before they happen.
What is Poka-Yoke?
Most Yaskawa drives are rated for this overload capacity for 60 seconds.
What is 150%?
The power factor of a system is the cosine of this angle.
What is the phase angle or the angle between voltage and current?
Auxetic materials, like certain foams, have a negative value for this property, meaning they get wider when stretched.
What is Poisson's ratio?
In the Back in My Day episode of Yaskawa's VFD Vibes podcast, the host reflects on this groundbreaking drive—the world’s first IGBT-based unit launched by Yaskawa.
What is the G3 drive?
This Japanese phrase meaning "horizontal development" refers to the practice of applying a successful improvement or countermeasure from one process to others to prevent similar issues.
What is Suihei Tenkai
This is the maximum inverter output frequency listed for GA800 drives
What is 590 Hz?
The world's first transistor was made with this fragile and toxic element.
What is germanium?
This dimensionless number compares inertial to viscous forces in fluid flow.
What is Reynolds number?
During the Harmonic Headache episode of Yaskawa's podcast VFD Vibes, listeners learn that this IEEE guideline sets the limits for allowable harmonic distortion.
What is IEEE 519?
