Description
Designed for high-performance CNC machining applications, the MDS-C1-CV-260 serves as a centralized power regeneration converter module within the MDS-C1 Series architecture. This unit efficiently rectifies AC input power to a stable DC bus voltage while managing regenerative energy returned from servo and spindle drives during deceleration, returning clean power back to the main supply grid. Engineered with an integrated Intelligent Power Module (IPM), it minimizes thermal losses and optimizes system-wide energy efficiency in heavy-duty motion control environments.
By coordinating power distribution across multiple drive units, the MDS-C1-CV-260 stabilizes system voltage levels and protects delicate control components from transient voltage spikes. Its robust construction and built-in diagnostic communication channels ensure seamless synchronization with Mitsubishi Electric control units and servo drives.

Installation Guidelines
-
Mounting Orientation: Install vertically on a flat, non-flammable back panel to ensure proper heat dissipation and vertical airflow.
-
Environmental Clearance: Maintain a minimum clearance of 100 mm above and below the unit, and 40 mm on both sides for optimum ventilation.
-
Grounding: Connect the dedicated protective earth (PE) terminal to the main system ground bus before applying primary power.
-
Cable Shielding: Ensure all communication and low-voltage control cables are properly shielded and physically routed away from high-voltage AC input and DC bus cables to prevent electromagnetic interference (EMI).
