Product Description:

The MMC-SD-2.0-230-D is an AC servo drive produced by Kollmorgen for the MMC Standalone Smart Drives series. It integrates the power electronics, control logic, and safety relays required to run a single motion axis, turning a 230 V supply into a modulated output that commands motor speed and torque in automated equipment such as packaging lines and material-handling stages. This arrangement allows the drive to support precise axis control in compact machine layouts where motor regulation and protective functions are handled in one unit.

This drive sustains a continuous phase current of 7.1 A RMS, which supports steady operation at rated load. Its thermal design supports a continuous mechanical output of 2 kW from a 230 Vac source, while short acceleration bursts are handled with a peak current of 30 A. The input side draws up to 18 A RMS under full load and limits transient line excursions through a bus over-voltage trip set at 420 VDC. Control electronics are powered separately, drawing 9 W at 375 mA, and they have an inrush current of 1.5 A for 10 ms, while the main power section can see 70 A of inrush when the capacitors charge. An internal brake relay switches dynamic braking energy onto a resistor chain to help keep the DC bus within range.

The housing measures 257.18 mm tall, 119.05 mm wide, and 155.56 mm deep, and it dissipates 70 W of heat to ambient air through its finned aluminum chassis. Brake control contacts are rated for 831 VA, allowing rapid engagement of external dump resistors during deceleration. A bulk capacitance of 1880 µF stabilizes the internal DC bus against load changes and line sags, while magnetic components absorb the inrush current noted above. Overall mass is kept to 2.59 kg, so the unit can be panel mounted without added supports, and its compact footprint leaves room for adjacent fieldbus adapters and I/O modules.
