Yaskawa AC Drives and VFDs – High Precision Electrical Drive Systems
World‑class vector control, seamless integration, and operational reliability for the most exacting motor‑driven processes.
In the domain of industrial electrical motor control, few names command the respect earned by Yaskawa. As the company that pioneered vector control technology and owns the largest installed base of Variable Frequency Drive units worldwide, Yaskawa has shaped the way induction and permanent magnet motors are controlled. Yaskawa AC Drives and VFDs are far more than speed‑varying devices; they are precision electrical motor control platforms that deliver open‑loop vector accuracy within ±0.1%, integrated machine safety, and a suite of application‑specific software that reduces external automation hardware. For plant engineers who cannot afford production variability, Yaskawa’s portfolio of AC Drives & VFDs offers a proven path to tighter process control and lower energy expenditure.
The installation numbers speak for themselves: over 30 million Yaskawa Variable Frequency Drive units are in service across every continent, in applications ranging from simple HVAC fan control to multi‑axis synchronised motion in automotive assembly. This breadth of deployment has generated an immense reservoir of application knowledge, which is embedded in the drive firmware as parameter defaults, auto‑tuning routines, and protective functions that anticipate real‑world fault conditions. For facilities seeking to standardise on a single, scalable electrical motor control supplier, Yaskawa AC Drives and VFDs provide a unified platform that spans fractional kW to multi‑MW ratings without sacrificing performance or connectivity. HANI, as a system integration partner, has standardised on Yaskawa for many retrofit projects precisely because of this breadth and the resulting reduction in spares complexity.
The Yaskawa Engineering Philosophy – Electrical Motor Control Without Compromise
Every Yaskawa drive, from the compact GA500 to the high‑performance GA800, is built around a proprietary high‑speed processor and a current vector control algorithm that executes 12,000 calculations per second. This processing headroom allows the Variable Frequency Drive to maintain full torque at zero speed, ride through brief supply interruptions, and actively dampen mechanical resonances—all without external sensors. For heavy‑duty electrical motor control applications such as extruders, hoists, and ball mills, the drive’s fast torque response and precise speed regulation translate directly into product quality and machine protection.
Yaskawa GA Series – Technical Specifications
The table below profiles the current GA family of Yaskawa AC Drives and VFDs, which spans the full range of industrial electrical motor control requirements. All models support induction, permanent magnet, and synchronous reluctance motors, and are compliant with IEC 61800‑3 (EMC) and IEC 61800‑5‑1 (safety).

Energy Performance and Total Cost of Ownership
The financial case for Yaskawa AC Drives and VFDs is anchored in the physics of fluid handling and the quality of the electrical motor control algorithm. Centrifugal loads governed by the affinity laws consume power proportional to the cube of rotational speed; a 20% speed reduction yields a 50% power reduction. Yaskawa drives maximise this opportunity with an automatic energy‑saving function that dynamically adjusts the magnetising current to the minimum necessary for the load. In variable‑torque applications such as HVAC fans and water pumps, this function typically adds 5%–10% to the energy reduction already achieved by speed control alone.
Beyond the kWh savings, Yaskawa electrical motor control extends the life of connected motors and mechanical transmissions. The soft‑start function limits inrush current to 150% of rated (versus 600%–800% for direct‑on‑line starting), eliminating the winding stress and torque pulsations that degrade insulation and fatigue couplings. For processes where unscheduled downtime is financially severe, the predictive maintenance functions built into every Variable Frequency Drive—monitoring I²t, DC link capacitor ESR, and cooling fan life—allow maintenance teams to replace components during planned outages rather than in emergency response mode.
Industrial Sectors Relying on Yaskawa Electrical Motor Control
The flexibility of Yaskawa AC Drives and VFDs is demonstrated by their deployment across capital equipment and continuous processes alike. The common electrical motor control core ensures that lessons learned in one sector transfer readily to another.
HVAC & Water Infrastructure
Chillers, cooling towers, and booster pumps utilise Yaskawa Variable Frequency Drive technology to match flow to demand. The IP55‑rated GA700 is often installed adjacent to the motor, eliminating control panel cost. The built‑in PID and pump cascade logic of AC Drives & VFDs from Yaskawa can control multiple pumps without a PLC.
Machine Tool & Robotics
Spindle drives and servo axes in CNC machines and robots rely on Yaskawa’s closed‑loop electrical motor control for nanometre positioning. The Variable Frequency Drive acts as a motion controller, executing complex electronic camming and interpolation profiles directly.
Material Handling & Logistics
Conveyors, stacker cranes, and automated storage and retrieval systems (AS/RS) benefit from the compact footprint of the GA500 and the integrated Ethernet connectivity that ties Yaskawa AC Drives and VFDs into warehouse control systems.
DriveWizard and the Digital Ecosystem
A Yaskawa Variable Frequency Drive is commissioned and maintained using DriveWizard, a Windows‑based tool that provides an intuitive graphical interface for parameter setting, trending, and fault diagnosis. The software communicates over USB or Ethernet, allowing an engineer to configure an entire electrical motor control system from a laptop without opening the drive enclosure. For multi‑drive installations, DriveWizard can clone parameter sets across identical drives, reducing commissioning time by an order of magnitude. The tool also hosts Yaskawa’s validated application macros—pre‑configured parameter blocks for common tasks such as constant pressure pumping, winding, and traverse motion—that eliminate the need to start every configuration from a blank slate.
The Yaskawa electrical motor control platform also supports direct OPC UA communication, enabling the drive to publish performance and diagnostic data to IT‑level analytics platforms without intermediate gateway hardware. This native digital capability is a key differentiator for plants pursuing Industry 4.0 or smart manufacturing initiatives, as it allows the Variable Frequency Drive to serve simultaneously as an actuator and a condition‑monitoring sensor.
