Product Description:
The DMC2 50412 is a single-axis drive module produced by Danaher and supplied under the DMC Motion Controllers series. It regulates permanent-magnet or induction motors in automated machinery, converting power from a regulated DC bus into a variable output that aligns motor speed with process demand. Within an automation cell, the unit functions as the current-loop element of the control system, accepting speed or torque commands and modulating the connected motor accordingly.
The controller connects to a DC link rated at 570 VDC, so upstream rectifiers or bus supplies must be sized for that voltage. At an ambient temperature of 40 °C, it can deliver a continuous mechanical output of 1.4 kW, drawing a root-mean-square phase current of 2.2 A while accommodating peak demands up to 12 A during acceleration. Efficiency at that continuous operating point reaches 95%, limiting cabinet heat generation and reducing auxiliary cooling needs. The minimum supported motor inductance is 10 mH, so lower-inductance windings require external reactors to preserve current stability. Speed regulation is supported by a linearity error of less than 1 percent and an electrical speed range of 1:9000, allowing precise low-speed positioning without sacrificing top-end velocity.
The drive has a continuous current ceiling of 4 A when the ambient temperature remains at 40 °C. The current loop is updated at 2 kHz, while the power stage switches at 4 kHz; this combination supports smooth torque production with minimal ripple. The enclosure is rated at IP20, so the unit must be mounted inside a suitable cabinet that prevents contact with internal electrical components. Its aluminum chassis measures 234 mm high, 46 mm wide, and 227 mm deep, allowing the module to fit into dense multi-axis layouts. The unit weighs 2.7 kg, which should be considered when selecting mounting hardware and arranging support within the cabinet.
