Product Description:
The MMC-SD-2.4-460 is a standalone smart drive produced by Kollmorgen within the MMC Standalone Smart Drives series. As a compact servo amplifier, it receives three-phase mains power and regulates motor torque and speed for positioning, conveying, and coordinated motion tasks in automated machinery. Integrated control, power, and regenerative circuitry allow the unit to operate as the primary motion component in an axis panel, reducing external wiring and simplifying cabinet layouts.
The drive delivers a continuous motor phase current of 5.5 A, supporting steady-state loads while remaining within its thermal limits. When connected to a 460 VAC supply, it can provide up to 2.4 kW of mechanical output for medium-frame servomotors in packaging or material-handling lines. The input hardware accommodates 3.33 kVA of apparent power, which determines the required transformer and breaker capacity on the mains side. Internal energy storage totals 240 µF across the DC bus, helping the voltage remain stable during rapid load changes. Line energization follows a 7.81 A RMS inrush profile, limiting the initial demand placed on upstream contactors. A nominal input current of 4.18 A RMS and a bus-link capacity of 2.0 kW allow multiple MMC units to share power without oversized feeders. The feedback ports accept encoder signals at frequencies up to 720 kHz, supporting high-resolution position loops during precise axis movement.
Dynamic loads are supported by a peak output current of 11.0 A, providing short-term acceleration torque before thermal rollback engages. Resistive braking is coordinated through a shunt switch that activates at 780 VDC. With a minimum resistance of 130 Ω, the braking circuit can dissipate 5 kW of regenerated power, while the internal capacitors absorb 22 J per cycle. Continuous power loss is limited to 60 W, allowing installation in sealed enclosures with moderate airflow. The housing weighs 10 lb, which makes it easier to position and secure during panel installation without placing excessive load on the mounting surface.
