설명The NFX9000 adjustable frequency AC Drives are designed to provide adjustable speed control of 3-phase motors. These microprocessor-based drives have standard features that can be programmed to tailor the drive’s performance to suit a wide variety of application requirements. The NFX9000 volts-per-hertz product line utilizes a 32-bit microprocessor and insulated gate bipolar transistor (IGBTs) which provides quiet motor operation, high motor efficiency and smooth low speed performance. The size and simplicity of the NFX9000 make it ideal for hassle-free installation where size is a primary concern. Models rated at 240V, single- or 3-phase, 50/60 Hz are available in sizes ranging from 1/4 to 2 hp. Models rated at 115V, single-phase, 50/60 Hz are available in the 1/4 to 1/2 hp size range. The standard drive includes a digital display as well as operating and programming keys on a removable keypad. The display provides drive monitoring and diagnostic information. The keys are utilized for digital adjustment and programming of the drive plus operator control. Separate terminal blocks for control and power wiring are provided for customer connections. The drives feature RS485 serial communications.
