Product Description:
The M.3000.0470 is a standalone smart drive released by Kollmorgen within the MMC Standalone Smart Drives series. Designed as a three-phase servo inverter for machine automation, it converts fixed-frequency mains power into controlled voltage and frequency for precise motor operation. A dedicated 24 VDC control supply powers the internal logic, drawing 1050 mA and consuming 25 W. Feedback data travel through a BiSS interface, allowing the unit to close high-resolution position loops without supplemental encoder converters. The drive connects to a three-phase power bus and supports decentralized installation near the load.
Under steady conditions, the drive delivers a continuous output current of 36.5 A and a sustained mechanical output of 16.0 kW. The incoming supply has a nominal current of 21.1 A RMS and an apparent power demand of 16.8 kVA; these values help determine appropriate upstream protection and cabling. At startup, the rectifier section can draw a momentary inrush current of 39.2 A RMS, so the connected power system must accommodate the initial surge. The inverter can synthesize carrier-based output at frequencies up to 450 Hz, allowing operation with high-speed spindles and permanent-magnet motors. Energy is buffered by a 1230 µF DC link that smooths voltage ripple during regenerative transients.
During dynamic motion, the current can rise to 73.0 A for short intervals, providing additional torque for acceleration and disturbance rejection. Excess bus voltage from overhauling loads is limited when the DC link reaches 780 VDC, at which point an internal shunt switch diverts energy to an external resistor. During normal operation, the electronics dissipate 390 W, so forced-air cooling must be provided to maintain an acceptable operating temperature. The chassis weighs 35 lb, which supports panel installation without imposing excessive weight on the mounting structure. Adequate clearance around the cooling path is necessary to prevent recirculated warm air from reducing heat removal.
