Designed to use with AC vector motors with open loop flux vector designs. Leeson SM2 drives can be used in a wide range of industries and applications, from pumps anf fans to OEM equipment. Various modes of operation: Open loop flux vector (speed or torque); V\/Hz (constant or variable); Enhanced V\/Hz with auto-tuning. \u003c\/p\u003e\n\u003cp\u003eMore features of the 174628.00 include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThree phase input\u003c\/li\u003e\n\u003cli\u003eNEMA 1 IP31 Enclosure\u003c\/li\u003e\n\u003cli\u003eUser friendly keypad\u003c\/li\u003e\n\u003cli\u003eOutput Frequency: 500 Hz Std., 1000 Hz optional\u003c\/li\u003e\n\u003cli\u003eSelectable Logic Assertion: Positive logic input (PNP current sourcing); Negative logic input (NPN current sinking)\u003c\/li\u003e\n\u003cli\u003eLoss of follower management\u003c\/li\u003e\n\u003cli\u003eSpeed commands: keypad, jog, floating point control\u003c\/li\u003e\n\u003cli\u003eVoltage: Scalable 0-10 VDC\u003c\/li\u003e\n\u003cli\u003eCurrent: Scalable 4-20 mA, potentiometer,\u003c\/li\u003e\n\u003cli\u003e8 Preset speeds\u003c\/li\u003e\n\u003cli\u003eProcess control: PID modes: direct or reverse acting,\u003c\/li\u003e\n\u003cli\u003ePID sleep mode\u003c\/li\u003e\n\u003cli\u003eVoltage and Current monitoring\u003c\/li\u003e\n\u003cli\u003eReal time monitoring: 8register fault history, software version drive network ID, DC bus\u003c\/li\u003e\n\u003cli\u003eVoltage (V), motor voltage (V), output current (%) Motor current (A), motor torque (%), power (kW) Energy consumption (kWh), heatsink\u003c\/li\u003e\n\u003cli\u003eTemperature(°C), 0-10 VDC input (user defined), 4-20 mA input (user defined) PID feedback (user defined), analog output (% load, %torque, kW), network speed (baud rate), terminal continuity,keypad status\u003c\/li\u003e\n\u003cli\u003eElapsed run time (hours), elapsed power on time (hours)\u003c\/li\u003e\n\u003cli\u003eStandards: UL, cUL, CE, GOST, C-Tick \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eFrequent Leeson VFD questions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cb\u003eHow much space is required around the variable speed drive?\u003c\/b\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDepending on the VFD series that is being used, maintain the following spacing around each VFD: \u003cb\u003eMicro Series:\u003c\/b\u003e 2 inches below 5 HP; 4 inches for 5-25 HP; 6 inches for 25-60 HP; 8 inches above 60 HP. \u003cb\u003eSM Plus Series \u0026amp; SM-Series:\u003c\/b\u003e 1 inch on each side and 2 inches on the top and bottom for 10 HP and below; 1inch on each side and 4 inches on the top and bottom for 15-25 HP.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e \u003cb\u003eWhat is the maximum distance the motor can be from the VFD?\u003c\/b\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe motor should be located as close to the VFD as possible (100 feet or less). For applications where the motor is more than 100 feet away from the drive, a load reactor or dV\/dt filter should be installed. As motor lead length increases, voltage spikes generated by the VFD’s output transistors become amplified, and may result in motor failure. Adding an output reactor or dV\/dt filter reduces the spikes.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e \u003cb\u003eCan you program a VFD while it is running?\u003c\/b\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e Yes, but the changes will not take effect until after the VFD is restarted.\u003c\/p\u003e","brand":"Leeson","offers":[{"title":"Default Title","offer_id":40559741501526,"sku":"174628","price":1988.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/0260\/1302\/files\/article_17461500_still01_9_17461500_01_8.jpg?v=1753820194","url":"https:\/\/sqone.com\/products\/leeson-174628","provider":"Square One Electric Motors \u0026 Pumps","version":"1.0","type":"link"}
