As a dedicated supplier of industrial automation solutions, Rossonix Co., Limited is proud to offer the Yaskawa CIMR-G7A4075 Varispeed AC Drive. Established in 2011, we have built a strong reputation for connecting global markets with high-quality, reliable components from leading manufacturers. This 75kW (100HP) drive represents the proven performance of Yaskawa's G7A series, engineered to deliver precise speed control, robust operation, and enhanced energy efficiency for demanding industrial applications. We understand that your machinery's reliability is paramount, which is why we source drives that combine advanced technology with durable construction.
The core value of this AC drive lies in its ability to optimize motor performance, leading to significant operational benefits. By precisely controlling the speed and torque of standard AC induction motors, it helps reduce mechanical stress, lower energy consumption, and improve overall process control. Whether integrated into pump systems, fans, conveyors, or machine tools, the CIMR-G7A4075 provides a versatile and powerful solution for modern industrial automation needs.
Key Features and Technical Advantages:
High-Performance Control: Features advanced PWM control for smooth motor operation across a wide speed range, minimizing torque ripple and ensuring stable performance even at low speeds.
Robust Power Design: Rated for 75kW (100HP) output, it is built with high-quality IGBTs and a sturdy heatsink design to handle continuous duty cycles and demanding load conditions.
Wide Voltage Compatibility: Accepts a three-phase input voltage range of 380-480V AC, offering flexibility for integration into various global power systems without requiring external transformers in many cases.
User-Friendly Operation: Equipped with a digital keypad for easy parameter setting, monitoring, and diagnostics. Multiple control modes (V/f, sensorless vector) are available to match specific application requirements.
Comprehensive Protection: Incorporates multiple protective functions including overcurrent, overvoltage, undervoltage, overload, and short-circuit protection to safeguard both the drive and the connected motor.
Energy Saving Capabilities: Includes automatic energy optimization features that adjust voltage output based on the actual load, reducing wasteful power consumption and lowering operational costs.

Frequently Asked Questions (FAQ):
What is the main application for this VFD?
This drive is primarily used for variable speed control of three-phase AC induction motors in industrial settings such as pumps, fans, compressors, and conveyor systems.Can it be used with a single-phase power supply?
No, this model requires a three-phase AC power input (380-480V). For single-phase applications, a different model or an external phase converter would be necessary.Does it include a braking resistor?
A braking resistor is not included as standard. It is an optional accessory that can be added for applications requiring frequent deceleration or overhauling loads.What communication protocols are supported?
Standard models typically feature an RS-485 interface. Support for specific protocols like Modbus RTU is often available and can be confirmed upon request.Is programming software required for setup?
Basic parameter setup can be done directly via the built-in digital keypad. For advanced configuration or batch programming, dedicated PC software is available from Yaskawa.What is the typical delivery lead time?
Lead time varies based on stock availability. As a trading company with established logistics, Rossonix can provide current stock status and estimated shipping timelines upon inquiry.Are spare parts readily available?
Yes, as a widely used series from a major manufacturer, key components and spare parts for the G7A series are generally available through the supply network.What environmental conditions is it rated for?
It is designed for installation in a controlled environment (IP20). For dusty, damp, or washdown areas, an appropriate external enclosure is recommended.
