Frequency Converter GA700
The versatile Yaskawa frequency converter GA700 for industrial applications is distinguished by great flexibility, small dimensions, and built-in features. Its encoder connections allow for more precise and accurate control of the motor’s speed and torque. Manage GA700 easily with your smartphone and use its powerful configuration tools for easy set-up, maintenance and troubleshooting to save valuable time.
Provide superior control with frequency converter
In modern applications a need for high-precision positioning and synchronization of electric motors is constantly increasing, not only to save energy, but also to reduce scrap and maintenance costs. The reliable control is provided by frequency drives that change the speed or torque of electric motors.
With a flexible motor control, powerful and extendable functionality and a broad power range, the Yaskawa GA700 frequency converter meets the above requirements. This incredibly reliable, powerful, and easy-to-use drive of choice for almost any industrial application task, is designed for 10 years of maintenance-free operation.
Let the GA700 benefits impress you
Flexibility, ease of use, and a sustainable design of GA 700, all offer the best value proposition for your application.
Check out the driver’s main benefits:
Improve usability with LCD keypad
You can easily program and operate GA700 with a high-resolution graphical keypad that supports 13 languages. A Setup Wizard and the intuitive full text menu structure simplify drive setup and save valuable time.
LCD keypad features:
- Copy function for 4 sets of parameters
- Data logging on Micro-SD card
- Real-time clock
- Available with Bluetooth for connecting a mobile device
- Automatic backup function
- Standard RJ45 cable connection
Effortlessly integrate frequency converter to network
GA700 is adapted to various factory automation networks as it supports the major industrial communications and connection topologies. Through available built-in protocols and/or dedicated communication options (RS-485 MEMOBUS/Modbus protocol, 115.2 kbit/s communication speeds) you can reduce wiring when connecting to an upper level controller or PLC.
The embedded +24 VDC control power input allows for maintaining the network communication even during main power loss, thus enabling you continuous monitoring and faster start up on power recovery.
Up to five frequency drives can be accessed through just one fieldbus option card, thus providing a cost effective solution with less wiring effort.
Control a variety of motors with one drive
The frequency converter enables you precise control of induction-, permanent magnet- and synchronous reluctance motors, providing versatility to run a wide range of applications with single drive. Moreover, it can run all of these motor types without comprehensive tuning owing to the new EZ vector mode.
In addition to the open loop speed or torque control, you can also use the GA700 for the more advanced closed loop control (CLV-closed loop vector), as it features incremental (PG-X3) and complimentary encoder (PG-B3) connections. Using the feedback from the motor and the drive’s complex control algorithm, the closed loop control allows for highly dynamic and efficient performance across the motor’s full speed range. The AC drive’s high-precision absolute and relative positioning enhance the accuracy of the results.
Run a variety of applications with one drive
GA700 unlocks great energy saving potential in various applications, automatically optimizes the motor efficiency for any speed and load condition and minimizes overall losses. By running your application at maximum efficiency it lowers energy cost.
“One-for-all” features at a glance:
- Tuning-less with EZ vector
- Open/closed loop speed or torque control
- Induction/permanent magnet motors
- 590 Hz max. output frequency
- Zero speed control without encoder
- Synchronous reluctance motor control
- Motor speed control range in closed loop mode of 1:1500
- Automatic energy efficiency optimization function
Benefit from the flexible package design
With its flexible package design the GA700 enables a reliable operation under a variety of environmental conditions. You can put this AC drive in a control cabinet or on a wall, in a clean environment, or in a harsh one.
There are several installation designs available, with many advantages:
Convenient set-up and monitoring
The GA700 provides a user-friendly self-guiding navigation menus and start-up wizards, which make the programming and set-up faster and easier than ever. DriveWizard and DriveWizard Mobile, together with the Yaskava Drive Cloud, all allow for your quick and easy drive management anywhere and anytime.
At the same time, DriveWorksEZ, an icon-based, drag-and-drop graphical environment, further enhances your programming experience. With its help, you can create or add programmable functions for your application in no time by drag-and-drop function blocks. These functions can tailor the drive to meet various machine and application requirements without external controllers (e.g., PLCs) or additional controller hardware options. This helps you reduce your business costs. The online diagnosis tool supports testing.
