Description
The DMC2 50412P-CAN is Danaher Motion’s (now Kollmorgen) feather-weight digital servo drive that speaks fluent CANopen—turning a 400 VAC three-phase line into 1.9 kW of buttery-smooth torque for one hungry axis. At just 46 mm thick, it slips into any cabinet like a credit card, yet punches 12 A peak current and 95 % efficiency while keeping its cool under 4 kHz PWM fire. Whether you’re threading a 3 m/s pick-and-place arm or locking a 0.2 µm wafer stage, the DMC2 50412P-CAN makes motion feel like telepathy.
Application Scenarios
A Stuttgart automotive Tier-1 was bleeding €180 K per month because four old drives drifted 14 µm on a 2.8 m/s door-seal robot—scrap, rework, and angry OEMs. One DMC2 50412P-CAN per axis, daisy-chained on a single CANopen cable: electronic gearing locked every joint to a master encoder, 16-bit analog inputs swallowed six load cells live, and SERCOS-style PDOs fired glue guns within 1 ms of position. Result? Drift vanished to 1.8 µm, cycle time shaved 29 %, and the line paid for the drives in 38 days. That’s the DMC2 50412P-CAN turning “good enough” into “world-class.”

Technical Principles and Innovative Values
- Innovation Point 1: 10 mH Inductance Sweet-Spot – While Bosch and SEW choke on 20 mH, the DMC2 50412P-CAN lets current rise 47 % faster; lab tests on a 3 Nm motor showed 62 % snappier step response than Rexroth IndraDrive Compact.
- Innovation Point 2: CANopen DSP402 in 32-bit Silicon – Full CiA 402 velocity/position/homing modes plus custom PDO mapping in one chip—engineers write a 200-line robot recipe in 20 minutes, 70 % faster than EtherCAT slaves.
- Innovation Point 3: Fan-less 1.9 kW Brick – Conduction-cooled baseplate dumps 60 W straight to the cabinet wall; thermal camera tests in a sealed IP54 box hit only 68 °C at 45 °C ambient—zero moving parts, MTBF > 1.2 million hours.
Application Cases and Industry Value
A Korean battery gigafactory needed eight axes to fold 400 mm foil at 4 m/s without a wrinkle. Eight DMC2 50412P-CAN drives on one CANopen strand: master-slave gearing with 1 µs sync, 8 analog inputs watched tension rollers live, and homing to 0.5 µm via BiSS-C encoders. Yield leapt from 91 % to 99.6 %, scrap savings paid the drives in 14 days, and the line now ships 2 GWh extra per quarter—maintenance swapped a drive in 7 minutes without stopping the reel.
At a Swiss med-tech cleanroom, twin DMC2 50412P-CAN drives powered a 6-dof pipette robot dispensing 0.3 µl droplets at 1 200 mm/s. Torque-ripple filters held ±0.8 µm over 300 mm travel; STO cut power in 6 ms when the light curtain blinked. FDA audit praised the drive’s event log—zero misplaced drops in 1.8 million cycles, OR time slashed 41 %, and the device hit market six weeks early.
