Product Description:
The M.1302.8137 is a standalone smart drive produced by Kollmorgen for the MMC Standalone Smart Drives series. Intended for servo-based automation cells, the unit accepts three-phase mains power, rectifies the supply, and modulates the resulting DC bus to run compatible Kollmorgen motors. Position or velocity control loops are closed inside the drive, allowing it to regulate connected motors without a separate motion controller for these functions. Combining logic and power electronics in one enclosure simplifies panel layouts in packaging, material-handling, and light-machining systems.
The controller operates from a nominal 460 V supply and draws a line current of 14.8 A RMS under steady load. Its inverter section delivers a continuous motor phase current of 18.0 A, while dynamic movements are supported by a peak current of 36.0 A for short intervals. Initial DC-bus charging can produce an inrush current of up to 27.7 A RMS, so the protective devices must tolerate this brief surge. Once energized, the drive can provide 8.0 kW of output power from an apparent input power of 11.8 kVA. Regenerated energy produced during commanded deceleration is routed to an internal shunt capable of dissipating up to 14 kW. This arrangement helps prevent excessive DC-bus voltage during rapid speed reductions or load reversals.
Internal switching devices and control electronics dissipate 204 W as heat, so adequate airflow is required to maintain an acceptable heat-sink temperature. A DC-bus capacitance of 705 µF smooths the rectified voltage and supplies energy during brief current demands. The shunt stage activates when the bus reaches 780 VDC. When active, the stage can conduct 9 A through a 44 Ω resistor and absorb 66 J during each braking event. The control electronics use a 24 V service supply with a current requirement of 1,050 mA, while the brake driver draws 0.5 A to hold a connected mechanical brake. The enclosure weighs 16 lb, allowing it to be mounted directly in medium-sized machine frames or control panels.
