Thesemicroprocessor-based driveshave standard features thatcan be programmed to tailorthe drive’s performance tosuit a wide variety ofapplication requirements.The NFX9000 volts-per-hertzproduct line utilizes a 32-bitmicroprocessor and insulatedgate bipolar transistors(IGBTs) which provide quietmotor operation, high motorefficiency and smooth lowspeed performance. The sizeand simplicity of theNFX9000 make it ideal forhassle free installation wheresize is a primary concern.Models rated at 240 volts,single- or three-phase,50/60 Hz are available insizes ranging from 1/4 to2 hp. Models rated at 115volts, single-phase, 50/60 Hzare available in the 1/4 to1/2 hp size range.The standard drive includes adigital display, operating andprogramming keys on thekeypad.The display provides drivemonitoring as well asadjustment and diagnosticinformation. The keys areutilized for digital adjustmentand programming of the driveas well as for operatorcontrol. Separate terminalblocks for control and powerwiring are provided forcustomer connections. Thedrives feature RS-485 serialcommunications.Features and BenefitsNFX9000 Adjustable Frequency AC DrivesFeatureCustomer BenefitV/Hz controlClearly laid out and easy to understandkeypad with four-character LED display,four status indicating LEDs, speedpotentiometer, and five function keysOne analog input, four programmable,intelligent digital inputs, oneprogrammable relaySerial communication port (RS-485)Single-phase or three-phase inputcapability on 115/240 Vac rated unitsStandards and Certifications●●●●NEMA, IEEE, NEC: Design StandardsUL ListedcUL ListedCE MarkedProvides 150% starting torque and advancedlow speed controlMost informative operator’s interface in thisclass of VFD, provided as standard.
