Yaskawa Electric America provides Industrial Control and Automation products to markets in the Americas. Yaskawa is the world's largest manufacturer of ac drives and motion control products, including adjustable frequency drives servo amplifiers, servomotors, machine controllers, and motion controllers.
P7 Drive: 208 to 240 VAC 5 to 150 HP, 480 VAC 5 to 500 HP
For industrial applications such as centrifugal fans and pumps, the P7 drive is an ideal choice. The drive 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 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. If the application requires programming, the P7 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. Providing the right power requirements is also easy with 208/240 and 480 volt ratings, built-in bus choke above 30 HP, common bus capability, and other energy savings options. Other features include motor auto-tuning and configurable options such as circuit breakers and fuses.
The P7 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, 0-10 V, 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.
