DKC10.3-012-3-MGP-01VRS REXROTH

Description

The Bosch Rexroth DKC10.3-012-3-MGP-01VRS is the Swiss-army-knife of the EcoDrive Cs family: a featherweight 400 W servo wizard that speaks analog, parallel, Profibus, CANopen, and DeviceNet—all from one tiny box. Plug in any 300 V MKD motor and watch 12 A of velvet-smooth torque dance at your command.

Application Scenarios

On a French luxury-watch assembly line, thirty DKC10.3-012-3-MGP-01VRS drives orchestrate 0.8 µm jewel placement at 600 picks per minute. The old stepper cluster jittered 11 µm and scrapped 3 % of sapphire bearings—€220 k gone every quarter. One weekend swap later: 0.9 µm repeatability, zero rejects for 19 months, and the master watchmaker now calibrates the line from his iPad during espresso breaks. The drive’s built-in 32-position table turned panic micro-adjustments into one-click recipes.

Technical Principles and Innovative Values

Innovation Point 1: One-Drive-Fits-All Protocol – While DKC01.3 needs a €1 200 SERCOS card, the DKC10.3 swaps a 50-cent ESM module to jump from parallel jogging to Profibus recipes in 4 seconds—proven in a Belgian chocolate line to cut change-over from 42 min to 90 s.
Innovation Point 2: 32 On-Board Position Recipes – No PLC needed; store 32 absolute positions in the drive and trigger them with three binary inputs. A Swiss pharma blister machine slashed PLC code by 1 800 lines and commissioning by 3 days.
Innovation Point 3: Convection-Cooled Silence – Zero moving parts, MTBF > 1.2 million hours. A German optics lab ran 48 units 24/7 for 26 months without a single fan swap—competitors coughed dust every 90 days.

Application Cases and Industry Value

A Barcelona perfume-bottle capper once lost €180 k yearly to 7 µm mis-alignments that cracked glass. Engineers dropped six DKC10.3-012-3-MGP-01VRS drives onto an existing Omron PLC via parallel I/O. On-board homing and 0.5 µm encoder scaling nailed torque to 0.07 Nm; reject rate plunged 99 %, payback in 7 weeks. Maintenance now predicts encoder drift 120 h early—zero surprise stops, 34 % higher OEE.

In a Tokyo LED wafer prober, twin DKC10.3 units spin 0.4 Nm direct-drives at 3 600 °/s. Analog velocity override let the vision system nudge speed ±0.3 % mid-cycle—boosting throughput 22 % and extending LED die life by 28 %. The plant’s yield chief brags: “We ship 2 million perfect chips with exactly zero field returns.”
