Product Description:

The MMC-SD-1.0-230-D is a standalone smart drive from the MMC Standalone Smart Drives series manufactured by Kollmorgen. As an integrated servo amplifier and motion controller, it regulates torque, velocity, or position for small-to-medium AC servomotors used on conveyors, indexers, and other automated axes. By combining power electronics with embedded control, the unit simplifies cabinet layouts and supports decentralized installation in industrial automation cells. That combined design lets one unit handle both motor control and local motion tasks without a separate amplifier mounted elsewhere in the cabinet.

The drive delivers a continuous output of 1 kW while maintaining a steady phase current of 3.5 A RMS. For rapid acceleration, it can supply a peak current of 15 A peak without exceeding its normal operating limits. Input demand stays within 2.0 kVA and draws a nominal line current of 9 A RMS, allowing installation on 230 V single-phase feeders. Internal monitoring trips if the DC link exceeds 420 VDC, protecting the bus capacitor and power devices. Power dissipation is limited to 37 W under rated load, and the logic section typically consumes 375 mA, with a brief 1.5 A inrush for 10 ms. The housing measures 9.69 in high, 4.69 in wide, and 6.12 in deep, so it fits standard sub-panel rails while leaving space for airflow.

The braking circuit can redirect up to 831 VA of regenerative energy through its relay, and the power stage tolerates a 70 A peak mains inrush at power-up. A mass of 5.6 lb (2.55 kg) keeps the unit light enough for door mounting while still providing a solid mechanical presence in vibrating equipment. Passive convection cooling removes heat without an external fan, which helps keep the installation simple. Terminal access remains practical in shallow enclosures because the housing does not project far from the mounting surface.
