The Yaskawa P7 VFD is for industrial applications such as centrifugal fans and pumps. The Yaskawa P7 VFD is provided in Normal Duty ratings with 110% overload capability. V/f control mode, network communication options, and an array of input/output options are available. The P7 VFD 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 6 languages. The keypad is intuitive and includes parameter copying to move a chosen set of parameters from one drive to another. The Yaskawa P7 VFD comes in power ratings of 208/240 and 480 volt ratings with built-in bus choke above 30 HP, common bus capability, and other energy savings options.

The Yaskawa P7 VFD 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 4 to 20 mA, 0-10V, and an assortment of programmable contacts. 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 factor by over 90%. With lower EMI/RFI emission and lower total harmonic distortion contribution, the P7 meets or exceeds the generally accepted power quality standards. Inherent motor protection features resulting from low noise/low carrier technology provides for longer lead lengths without additional motor protection devices. The optional P7/Bypass package is a 3-contactor style bypass, allowing motor operation from the drive or across the line. This facilitates drive maintenance while the motor continues to operate. The P7 has been designed to provide the features and options commonly needed for fan and pump applications.

P7 18-Pulse Drive 25-500 Horsepower

The Yaskawa P7 18-Pulse VFD is a variable torque rated AC drive, designed specifically for applications that require low total harmonic distortion at the drive input terminals and to meet the requirements of IEEE-519 (special applications) at the point of common coupling. The Yaskawa P7 VFD includes numerous built-in features such as Network Communications, PI, and energy-savings functions. The P7 18 Pulse Drive Design limits the total harmonic distortioni at the Drive Input Terminals to less than 8% Current Distortion and less than 3% Voltage Distortion. The Yaskawa P7 VFD meets or exceeds generally accepted power quality standards with lower EMI/RFI emission and lower total harmonic distortion contribution. Inherent motor protection features resulting from low noise/low carrier technology provide for longer lead lengths without additional motor protection devices.

An enhanced sleep function provides significant energy savings by minimizing operating hours. Under-torque detection, alerts the operator to conditions such as loss of load or broken belts. Energy savings control is an automatic output voltage adjustment in response to actual motor load. Real-time energy savings is based on motor algorithms. Motor efficiency is increased by several percent. Built-in kW-hour and kW display eliminates the need for external signal conditioner for energy monitoring. The standard enclosure is NEMA 1. NEMA 12 and 3R are optional. The optional Bypass package is 3-contactor style bypass, allowing motor operation from the drive or across the line. This facilitates drive maintenance while the motor continues to operate. The Yaskawa P7 18-Pulse VFD with Bypass has been designed for flexibility in providing the features and options commonly demanded by facility designers.

The Yaskawa G7 drive is the ultimate performance solution with increased speed and torque response to provide servo-like performance from an induction motor. The Yaskawa G7 drive has the world’s first 480V 3-level inverter architecture that eliminates or minimizes the installation problems associated with IGBT switching and protects the entire motor-drive system. The 3-level control eliminates peripheral components typically required to solve installation problems such as long motor cable leads, motor bearing life, audible noise, and common mode noise. The Yaskawa G7 drive performance makes it the ideal drive for high performance speed, torque, or position control applications. The Yaskawa G7 drive is the total solution for the unconventional, extreme performance applications. With high-end response for speed and torque loops, the G7 provides servo-like performance for superior motor control.

The Yaskawa G7 drive allows motor operation at very long cable lengths, meeting NEMA MG1 Part 31, with peak voltage being 30% less than conventional drives. With motor bearing current being typically 50% less than standard drives, the G7 provides four times the motor bearing life. The Yaskawa 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 Yaskawa G7 keypad is intuitive and includes memory for parameter settings, making it easy to transfer settings from one drive to another. The Yaskawa G7 / Configured package provides a G7 drive in either a NEMA 12, UL Type 1 (IP22 or IP54 depending on the exact rating) enclosure, with space for factory-mounted and wired options, such as reactors, filters, circuit breakers, fuses, network communications and I/O cards.

Programming and Software

The Yaskawa G7 drive uses Drive Wizard™ software for the PC and is available at no charge for upload, download, archiving, trending, and graphing. The Yaskawa 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 pre-written application-specific modules such as Motion Control or Electronic Lineshaft. The G7 drive supports the industry’s preference for open network architecture and connectivity with network choices such as EtherNet/IP, Modbus TCP/IP, Profibus-DP, DeviceNet, and others. The Yaskawa 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.
