Product Description:

The MMC-SD-1.0-230-DN is a standalone smart drive produced by Kollmorgen within the MMC Standalone Smart Drives series. Acting as a combined servo amplifier and motion controller, it delivers closed-loop control for brushless motors and coordinates axis motion in compact machines. In industrial automation, it replaces discrete drives and PLC cards, reducing cabinet space while maintaining deterministic performance for positioning, speed, and torque tasks. Its integrated control architecture allows one unit to manage motor commutation, motion sequencing, and local axis behavior without requiring a separate motion card.

The drive delivers a continuous phase output of 5 A, sufficient for steady-state loads up to its 1 kW mechanical rating, and can surge to 15 A for short acceleration periods. Incoming mains demand remains within the nominal 9 A RMS input current and draws about 2.0 kVA from a 230 V line. A bulk capacitor of 1880 µF smooths the DC bus so that current transitions do not propagate onto the supply. During startup, the capacitors charge through an inrush limiter, yet the initial peak still reaches 70 A, a value that helps determine fuse and contactor selection. These electrical values also help determine cabinet ventilation and upstream protection requirements.

Absorbed regenerative energy is limited to 51 J, which helps prevent overvoltage events when a motor decelerates. Field wiring is simplified by the 26-pin HD D-Sub drive I/O connector that carries eight digital inputs and four digital outputs, and each output can source up to 50 mA. For high-resolution motor feedback, the separate F1 port uses a 15-pin HD D-Sub layout. The input channels accept 24 V logic, allowing switches and control signals to connect directly to the embedded motion engine. This arrangement supports local connection of homing sensors, over-travel devices, and status signals without routing every point through a separate control module.
