Product Description:

The MMC-SD-2.0-230-A is a standalone smart drive produced by Kollmorgen within the MMC Standalone Smart Drives series. This module functions as a servo amplifier that rectifies incoming line power, shapes current, and supervises dynamic braking so attached AC motors follow precise speed and torque commands in automated machinery. Its integrated motion controller and power stage allow one compact unit to be mounted instead of separate controller and drive components, which helps reduce panel complexity and cabling. Because the control and power sections share the same housing, the unit supports a more compact layout for space-limited installations.

The drive delivers a continuous mechanical output of 2 kW, sustained through a phase current of 7.1 A RMS, and this pairing supports steady-state motion. During rapid acceleration, it can reach 30 A (0-Peak), providing short-term headroom without exceeding thermal limits. The inverter pulls up to 2.0 kVA from the mains, so upstream fusing and wiring must be sized for that apparent power. A bulk-storage capacitance of 1880 µF holds energy on the DC bus and helps limit voltage ripple. The control electronics draw 375 mA after an inrush of 1.5 A lasting 10 ms, and they dissipate 9 W during normal operation. Overall dimensions are 257.18 mm high, 119.05 mm wide, and 155.56 mm deep, while the assembly weighs 2.59 kg, which helps with enclosure layout and mounting support.

An internal brake relay rated at 24 VDC energizes the motor brake and can switch up to 831 VA of regenerative energy without external contactors. Bus supervision trips the drive if voltage exceeds 420 VDC, protecting the IGBT bridge and connected loads during regenerative events or incoming line fluctuations. Under rated conditions, the power stage dissipates 70 W as heat, so cabinet airflow or a heat sink must remove this loss. That thermal load must be managed continuously so the housing can shed heat during repeated motion cycles.
