Toshiba G7 Drive is a series of PWM (Pulse Width Modulation) Adjustable Speed Drives designed for industrial applications. It’s used to control the speed and torque of AC motors, providing precise control for various industrial processes.
Features
The G7 Series has the highest overload capabilities available. Rated at 110% continuous current, 150% up to 120 seconds* and 280% instantaneous current, the G7 can withstand load conditions that would cause other drives to fail.
- The G7 is ready for continuous, trouble-free operation in the most demanding manufacturing environments. It has an interrupting current rating of 200 KAIC. In addition, it is designed for an operating environment of -10 to 40°C at elevations of -1000 to 1000 meters.
Advanced Electronic Operator Interface
The G7ʼs Electronic Operator Interface (EOI) features a multi-line, graphics capable, plain English, backlit LCD. The EOI is so intuitive that the manual is usually not needed to make drive setting adjustments. The G7 has menu driven programming as well as direct access to the parameters. A high-reliability rotary encoder makes programming easy
Startup Wizard
- The Startup Wizard helps facilitate initial programming. The wizard leads you from beginning to end by asking
- a few simple questions about your application. Based on the answers provided, the wizard sets features and parameters suitable for your process. The G7 literally programs itself
Configurable
- Easy to remote-mount the display (up to 1000 feet)
- Real-Time Clock option
- Graphics capable LCD to aid in diagnostics
- Flash Upgradeable EOI Software
- Toshiba can help develop your custom application-specific wizards
Power Termination
- The G7 is designed to provide easy access to the DC bus. This allows for the implementation of common DC bus designs, access to the DC link and access to the dynamic braking IGBT, which is standard on the G7 drive. The Toshiba design solves your system and power quality issues
Built-In Communication
- In todayʼs fast-paced manufacturing world, coordinated systems require communications from drive-to-drive or drive-to-control systems. Toshibaʼs G7 comes standard with RS232/485 and TTL communications ports. In addition to the standard communications features, Toshiba offers a number of popular industrial communication protocol options including: Modbus RTU, Modbus Plus, Ethernet TCP/IP, Ethernet IP, Profibus DP, DeviceNet and Johnson Controls Metasys N2.
Adaptability
- The G7ʼs programmable discrete inputs may be configured to any of 68 different functions and are independently selectable for normally open or normally closed operation.
- The G7ʼs four multi-function analog inputs have independently adjustable bias and gain. From common potentiometers for speed control to analog summing for trim and process control, the configurability of the G7ʼs analog inputs are adaptable to your processes.
- The removable control terminal strip is available in dry contact, TTL or 120 VAC configurations and may be optionally DIN Rail mounted. The operator interface can be easily mounted remotely and configured for NEMA4/NEMA12 environments.
