The Yaskawa P7 VFD is for industrial applications such as centrifugal fans andpumps. The Yaskawa P7 VFD is provided in NormalDuty ratings with 110% overload capability. V/f control mode, networkcommunication options, and an array of input/output options areavailable.The P7 VFD is factory-programmed and ready to run. For operationalsimplicity and clarity, the LCD operator display has 5 lines x 16characters. It can be set to any of 6 languages. The keypad is intuitiveand 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 buschoke above 30 HP, common bus capability, and other energy savingsoptions.
The Yaskawa P7 VFD supports the industrys open architecture, open connectivitydemands with network communications choices such as DeviceNet, Profibus-DP, and others. Drive coordination withother 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-diodebridge can be operated in 12-pulse rectification mode, reducing inputcurrent harmonic distortion factor by over 90%. With lower EMI/RFIemission and lower total harmonic distortion contribution, the P7 meetsor exceeds the generally accepted power quality standards. Inherentmotor protection features resulting from low noise/low carriertechnology provides for longer lead lengths without additional motorprotection devices.The optional P7/Bypass package is a 3-contactor style bypass, allowingmotor operation from the drive or across the line. This facilitates drivemaintenance while the motor continues to operate.The P7 has been designed to provide the features and optionscommonly 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, designedspecifically for applications that require low total harmonic distortion at the drive input terminals and to meet the requirements ofIEEE-519 (special applications) at the point of common coupling.The YaskawaP7 VFD includes numerous built-in features such as NetworkCommunications, PI, and energy-savings functions.The P7 18 Pulse Drive Design limits the total harmonic distortioni at the Drive InputTerminals to less than 8% Current Distortion and less than 3% VoltageDistortion.The Yaskawa P7 VFD meets or exceeds generally acceptedpower quality standards with lower EMI/RFI emission and lower total harmonicdistortion contribution. Inherent motor protection features resultingfrom low noise/low carrier technology provide for longer lead lengthswithout additional motor protection devices.
An enhanced sleep function provides significant energy savings byminimizing operating hours. Under-torque detection, alerts the operatorto conditions such as loss of load or broken belts.Energy savings control is an automatic output voltage adjustment inresponse to actual motor load. Real-time energy savings is based onmotor algorithms. Motor efficiency is increased by several percent.Built-in kW-hour and kW display eliminates the need for external signalconditioner for energy monitoring.The standard enclosure is NEMA 1. NEMA 12 and 3R are optional.The optional Bypass package is 3-contactor style bypass, allowingmotor operation from the drive or across the line. This facilitates drivemaintenance while the motor continues to operate. The Yaskawa P7 18-Pulse VFD with Bypass has been designed for flexibility in providing the featuresand options commonly demanded by facility designers.
