P7 Drive
1/2 - 500 Horsepower Industrial Workhorse
F7 Drive

The F7 drive is the Industrial Workhorse of adjustable frequency drives. It is intended to handle every conventional drive application found in the typical industrial manufacturing plant from simple variable torque pumping to sophisticated networked material handling. With excellent performance and a wide array of configurations and options, the F7 can be the single drive platform for an entire facility. Network communications, plug-in I/O cards, custom software, and power/packaging options are among the many choices.For new installations or retrofits, the F7 is truly the Industrial Workhorse, perfect for every conventional application…and even some unconventional ones.
The F7 / Configured package provides an F7 drive in a NEMA 12 or NEMA 12 FVFF enclosure, with space for factory-mounted and wired options, such as reactors, filters, circuit breakers, fuses, network communications and I/O cards etc.

P7 Drive
5 - 500 Horsepower Industrial Fan and Pump Drive
P7 Drive

The P7 is designed for variable torque applications like Fans and Centrifugal Pumps. It is supplied with V/lf control and Normal Duty overload rating of 110% for one minute. Network communications, plug-in I/O cards, and power/packaging options are available. With an optional phase-shifting input transformer, the P7 dual-diode bridge can be operated in 12-pulse rectification mode, reducing input current harmonic distortion.
The P7 / Configured package provides a P7 drive in a NEMA 1 or NEMA 12 FVFF enclosure, with space for factory-mounted and wired options, such as reactors, filters, circuit breakers, fuses, network communications and I/O cards etc.

The P7 / Bypass package provides a P7 drive and 3-contactor bypass in a NEMA 1 or NEMA 12 FVFF enclosure, of sufficient size to mount and wire commonly selected options such as filters, fuses, network communications and I/O cards
G7 Frequency Drives
1/2 - 500 Horsepower The Ultimate Drive Solution
G7 Drive

This amazing AC drive is the ultimate performance solution with increased speed and torque response to provide servo-like performance from an induction motor. In addition, the G7 drive includes the world’s first Inverter architecture that eliminates or minimizes the installation problems associated with IGBT switching on 480 volt systems and protects the entire motor-drive system.

G7 drive performance makes it the ideal drive for high performance speed, torque, or position control applications. Several control modes are provided. In open loop vector mode, the latest flux observer algorithms extend speed range and provide maximum starting torque. In closed loop vector mode, 0.01% speed regulation and 1000:1 control range can be achieved. Zero-servo capability provides position control at zero speed.

The G7 drive has the world’s first 480V 3-Level Inverter architecture for total system protection. This patented 3-Level architecture can eliminate peripheral components typically required to solve installation problems sometimes encountered on 480 volt systems. The G7 allows motor operation at very long cable lengths, meeting NEMA MG1 Part 31, with peak voltage being 30% less than conventional. With motor bearing current being typically 50% less than standard inverters, the G7 provides four times the motor bearing life. Audible motor noise on the 480 volt G7 drive is 5-10 dB (20%) less than the prior generation drive, even when operating at half the carrier frequency. Common mode current is half that of conventional drives. The G7 power section includes built-in bus choke (most ratings), 12-pulse input capability (most ratings), common DC bus capability, and regeneration options.

The G7 drive has three auto tuning methods to optimize motor control, including the new static auto tuning which does not require load decoupling nor motor rotation. The LCD operator displays 5 lines x 16 characters, in any of 7 languages. The keypad is intuitive and includes memory for parameter settings, making it easy to transfer settings from one drive to another. To further aid in parameter management, Drive Wizard™ software for the PC is available at no charge, for upload, download, archiving, trending, and graphing.

The G7 drive has a large programming feature set to handle sophisticated industrial applications. If the standard feature set does not meet your specific requirement, the G7 can be programmed using DriveWorksEZ™. This is a PC-based, object-oriented, graphical icon programming tool that is friendly to the user. The drive firmware can also be modified by custom or rewritten application-specific modules such as Motion Control or Electronic Line shaft.

The G7 drive supports the industry’s preference for open network architecture and connectivity with network choices such as DeviceNet, Profibus-DP, Ethernet, and others.
 
The G7 is not intended for the simple, routine AC drive application, it is for the challenges. The G7 drive offers the ultimate performance, the best system protection, and the most flexible configurations of any drive available.

J7 Frequency Drive
1/8 - 5 Horsepower General Purpose AC Drive
J7 Drive
Micro size V/F Ideal OEM Drive
The J7 drive is a general purpose AC drive; its PWM design provides low motor noise and high starting torque, with a current overload rating of 150% for 60 seconds. V/f control makes this drive suitable for most general applications. The J7 is feature-packed, low cost, and compact. The digital operator includes a 3-digit LED status display. Digital programming covers 79 parameters. The J7 has five digital inputs (3 programmable), 1 analog input, and 1 digital output (programmable). An optional RS-485 Modbus RTU serial communication port is available. An ideal choice whenever low cost and small size are required.

Earlier versions of this product were named GPD 305/J7, GPD 305, or VS Mini J7.
