Product Description:

The MMC-SD-2.0-230 is a standalone smart drive produced by Kollmorgen within the MMC Standalone Smart Drives series. As a self-contained motion controller and amplifier, it converts three-phase 230 VAC into controlled variable-frequency power for a connected servo motor, enabling precise speed, torque, and position regulation in industrial automation cells. The housing measures 9.69 in in height, 4.69 in in width, and 6.12 in in depth, which supports panel installation where space is limited.

The drive supplies a continuous output current of 7.1 A RMS, which is the steady-state load the power stage can deliver without overheating. For transient events such as rapid acceleration, the current can rise momentarily to 30 A, providing additional torque before protective limits engage. When powered from a three-phase line, it draws up to 4.0 kVA at rated load, so upstream breakers and cabling must be sized for that apparent power. On the output side, the converter can deliver up to 2 kW to the motor when the mains voltage is 230 VAC. An internal monitor trips the bus if the DC link exceeds 420 VDC, helping prevent excessive stress on the semiconductors during regenerative events. Motion commands are digitized with 14-bit resolution, giving 16,384 discrete increments for loop calculations.

At power-up, the drive can draw an inrush current of 70 A, so the incoming supply path must tolerate the startup surge. The control electronics are supplied from a 24 V rail that demands only 375 mA, leaving headroom for sensors and network modules on the same supply. Mechanical integration is eased by the enclosure mass of 5.7 lb, which can be supported by standard back-panel standoffs. During full operation, the inverter dissipates 70 W as heat, and the line side can draw up to 18 A RMS, which guides cabinet cooling and branch protection sizing.
