The F7 Drive: This AC drive is the Industrial Workhorse that can handle every conventional application found within the typical industrial plant, from simple variable torque pumping to sophisticated networked material handling. All of this is possible with the smart and flexible design platform of the F7, providing both Normal and Heavy Duty ratings, four modes of control, network communication options, application-specific drive software, and an array of standard and optional input/output choices.

The F7 is factory-programmed and ready to run. For operational simplicity and clarity, the LCD operator display has 5 lines x 16 characters. It can be set to any of 7 languages. The keypad is intuitive and includes parameter copying to move a chosen set of parameters from one drive to another. If the application requires programming, the F7 makes it easy. Parameters are grouped in easy to use sets; quick start and advanced. To enhance parameter and data management, DriveWizard software for the PC is available at no charge, for upload/download, trending, and graphing.

This drive is designed for tough industrial environments. It is rugged and reliable, with an MTBF of 28 years. A variety of enclosure options provide the right environmental protection. The dual ratings, Normal and Heavy duty, enable the most economical match of overload capacity and starting torque for the application. Providing the right fit to power requirements is also easy with 208/240 and 480 volt ratings, built-in bus choke above 30 HP, 12-pulse capability above 30 HP, common bus capability, and regeneration options. Patented high slip braking can eliminate the need for dynamic braking resistors for high inertia loads. Other features include motor auto-tuning and a wide range of configurable options, such as breakers and fuses.

To provide the optimum control method, the F7 can operate in conventional V/f, V/f with encoder feedback, open loop vector, or closed loop vector mode. Drive performance can be further enhanced for a specific application with optional software.

The F7 supports the industry’s open architecture, open connectivity demands with network communications choices such as DeviceNet, Profibus-DP, and others. Drive coordination with other equipment is simplified with inputs and outputs for digital pulse train, 4 to 20 mA, -10 to +10 V, and an assortment of programmable contacts.

For new installations or retrofits, the F7 is truly the Industrial Workhorse, perfect for every conventional application…and even some unconventional ones
