Bulletin for Generation 7 AC Drives

Product catalog summary

Overview of Yaskawa Drives:
Yaskawa's Generation 7 Drives are designed for diverse industrial applications, available in models such as F7, G7, and P7, catering to performance needs from ½ to 500 horsepower. The F7 is for normal or heavy-duty loads, the G7 offers extreme performance with a 3-level inverter design, and the P7 is optimized for fans and pumps.

Microdrive Collection:
The Microdrive series includes V7, V74X, V7N, and J7 drives, ranging from 1/8 to 15 horsepower, ideal for machine mounting with features like open-loop vector control and embedded DeviceNet communications.

Performance and Technology:
Yaskawa drives offer control methods such as V/f, open-loop vector, and closed-loop vector control, with speed regulation options. They feature high-slip braking for high inertia loads and options for higher output frequency and zero-servo control. The 3-Level inverter architecture simplifies installation designs.

Quality and Reliability:
Yaskawa emphasizes quality and reliability, backed by ISO 9000 certification and rigorous testing. The company is recognized for customer satisfaction and is the only manufacturer in its field to receive the Deming Prize for quality.

Power Quality:
Generation 7 Drives address power quality issues with optional DC Bus Reactors and dual diode bridge rectifiers for harmonic mitigation, meeting strict harmonic requirements.

Ease of Use and Installation:
The drives are factory-programmed with intuitive operator displays and keypads. DriveWizard software supports parameter management and troubleshooting. Installation is simplified with split covers and detachable terminal boards.

Distribution and Support:
Yaskawa provides extensive training and support through distributors, offering worldwide services, including start-up assistance and repair. Customizable drive packaging options are available.

Applications:
The drives are suitable for industries such as plastics, air handling, elevators, oil & gas, packaging, textiles, pulp & paper, and more, handling both simple and complex automation needs.

G7 Drive:
The G7 drive features a 3-level inverter architecture, enhancing motor-drive system performance by reducing installation issues related to IGBT switching. It offers increased speed and torque response, suitable for applications requiring servo-like performance, with extensive networking and programming flexibility.

P7 Drive:
Designed for industrial fan and pump applications, the P7 drive offers variable torque and normal duty ratings, with features like speed search, energy-saving control, and network communication options.

J7 Drive:
A general-purpose AC drive, the J7 is compact and cost-effective, suitable for applications requiring low cost and small size, providing high starting torque and features like automatic torque boost and slip compensation.

V7 Drive:
The V7 series offers high performance with low motor noise and high starting torque, supporting V/f and open loop vector control methods, ideal for constant torque applications.

Common Features:
All Generation 7 Drives share specifications such as adjustable S-curve accel/decel, power loss ride-thru, high drive efficiency, and comprehensive protective features, supporting various input/output configurations and communication protocols.

Options and Accessories:
The document lists communication kits, analog and digital input/output kits, and remote operator kits, enhancing the functionality and adaptability of the drives.

Specifications and Components:
Components and kits related to remote operation and interface cables are listed, applicable to various drive models such as F7, G7, P7, V7, V7N, V74X, and J7.

G7 Three-Level Inverter:
The G7 drive is a 480V rated inverter with a 3-level power section, reducing motor winding failures, bearing failures, and instrument malfunctions by minimizing surge voltages, bearing currents, and common mode noise.

Auto-tuning Methods:
The P7, F7, and G7 drives support three auto-tuning methods: Resistance Auto-tune, Stationary Auto-tune, and Rotational Auto-tune, optimizing drive performance by analyzing motor parameters.

High Slip Braking (HSB):
HSB dissipates regenerative deceleration energy by creating a large slip condition, ideal for high inertia loads, reducing braking times by approximately 50% without needing a braking resistor.

Custom Software (CASE):
CASE software customizes drive functionality by replacing standard software, allowing for additional parameters, input/output functions, and custom sequencing.

DriveWizard™:
DriveWizard is a Windows-based tool for commissioning and troubleshooting Yaskawa drives, offering parameter management in a spreadsheet format and graphing functions for drive monitors.
