Product Details

The Danaher Motion MMC-SD-4, also known as Kollmorgen MMC-SD-4.0, belongs to the renowned MMC SmartDrive family, an obsolete integrated servo amplifier combining motion controller and power stage in one compact unit. This MMC SmartDrive amplifier delivers high-precision torque, speed and position closed-loop control for brushless AC servo motors. As an integrated servo drive, it embeds motion programming capability, built-in I/O and multiple fieldbus ports, eliminating the need for a separate master controller in many standalone automation stations. This Kollmorgen motion drive is widely adopted for overhauling legacy automated machinery, packaging lines and CNC retrofits; it is stocked as genuine replacement spare part for industrial motion control systems.

Supported Functions

This SmartDrive executes standalone motion programs and generates real-time servo commands for connected motors. It supports electronic gearing, cam profiling, homing, jogging and continuous positioning. It reads discrete input signals from sensors and limit switches, drives output relays and indicators, and handles safety interlock logic. It provides comprehensive fault recording and diagnostic data for commissioning and troubleshooting, and can work either as a standalone motion unit or as a slave drive under a higher-level host controller.

Core Functions

The all-in-one design merges motion control logic and power output to save cabinet space and reduce wiring. It supports flexible motion profiling and easy parameter backup via dedicated software. Its native feedback and bus interfaces guarantee compatibility with original legacy Kollmorgen servo motors and system racks. All mounting dimensions and pin definitions follow factory original specifications, requiring minimal rework during swap, and it serves as direct drop‑in substitution for existing MMC-SD-4 SmartDrive units.
