Bosch Rexroth DKC01.3-012-3-MGP-01VRS – EcoDrive 03 single‑axis servo drive for 3×230 V systems

The DKC01.3-012-3-MGP-01VRS is a compact Bosch Rexroth (Indramat) EcoDrive 03 digital servo drive, typically used to run MKD/MHD synchronous servo motors or 2AD asynchronous motors in packaging, printing, and handling equipment. One thing I appreciate is the MGP “multi-interface” firmware: it gives you straightforward analog ±10 V control and fast digital I/O without forcing a fieldbus redesign. From my experience, this variant is a safe pick for retrofits where you need a 12 A class axis on a 3×200–230 VAC supply and want predictable commissioning.

Company’s Order Placement Process and Guarantees

• Lead time: typically 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• 12 A axis rating – Sized for small to mid‑torque applications; common on feeders, unwinders, gantries, and indexers.
• 3×200–230 VAC mains – Fits low‑voltage three‑phase cabinets; simplifies brownfield upgrades on 230 V lines.
• MGP multi‑interface control – Analog ±10 V setpoint, step/direction, and fast 24 V I/O for enable, homing, limit, and mode signals.
• Motor compatibility – Works with Bosch Rexroth Indramat MKD/MHD synchronous servo motors and, in many cases, 2AD induction motors with appropriate feedback.
• Service/diagnostic port – RS‑232 for parameterization and trace with Rexroth tools; helpful during commissioning and fault analysis.
• Booksize form factor – Space‑efficient panel mounting; you might notice it fits neatly in existing EcoDrive 03 lineups.
• Integrated brake chopper – External resistor connection for dynamic deceleration on high‑inertia moves.
• Protection and monitoring – Overcurrent, overvoltage/undervoltage, and thermal monitoring to protect the drive and motor.

Technical Specifications

Application Fields

This model shows up a lot in brownfield upgrades where machine builders keep their motion profiles but refresh the axis hardware. Typical use cases include:

• Packaging machines – rotary sealers, cartoners, and intermittent index tables using analog speed or position loops
• Printing & converting – unwind/rewind tension control and register correction on 230 V panels
• Textile & woodworking – feed rollers, spindles, and positioning axes where fast I/O is sufficient
• Material handling – pick-and-place, small gantries, and tool changers with quick homing cycles

A packaging OEM told us their swap from a legacy analog amplifier to this DKC cut their changeover time because the I/O mapping and gain tuning were more forgiving—no PLC rewrite, just a tidy MGP setup and they were running.

Advantages & Value

• Reliability: EcoDrive 03 hardware has a strong field record; spare parts and knowledge are still widely available.
• Compatibility: Plays nicely with existing 230 V cabinets, MKD/MHD motors, and analog control architectures.
• Cost control: In many cases you keep your PLC code and wiring—savings come from shorter downtime and fewer new components.
• Support: We can assist with parameter backups, MGP I/O mapping, and selecting matched braking resistors and filters.

Installation & Maintenance

• Cabinet & mounting: Install vertically in an IP54 (or better) control cabinet. Allow top/bottom clearance for airflow; avoid heat sources directly beneath the unit.
• Wiring: Use shielded motor and feedback cables; bond shields 360° at the entry. Keep power and signal runs separated. Verify PE grounding and braking resistor sizing.
• Environment: Operate within 0…45 °C and low dust/moisture. If cabinet temps run high, derate or improve ventilation.
• Commissioning: Through RS‑232, save/restore parameter sets. Check motor nameplate data, feedback type, and current limits before enabling torque.
• Routine care: Annually check fan and heatsink cleanliness, terminal tightness, and brake resistor connections. Firmware updates should match MGP release “01VRS”.
• Safety: Lockout/tagout mains; verify DC bus discharge. Test E‑stop chain and hardware limits after any wiring change.

Quality & Certifications

• CE compliant; UL/cUL conformity is typical for this series
• RoHS alignment for electronic assemblies where applicable
• Manufacturer quality system: ISO 9001
• Warranty coverage: 365 days

Helpful Companion Parts (for quicker selection)

• Motors: MKD and MHD series (e.g., MKD071, MKD090) and, in many cases, 2AD induction motors
• Braking resistor: external resistor sized for the kinetic load and duty (EcoDrive 03 compatible)
• Mains line filter/reactor: to meet EMC and protect against supply disturbances
• Cabling: motor power cable with brake cores, feedback cable matched to the motor’s encoder system

If you’re replacing a legacy DKC in an older machine, send the drive ID plate and motor type. We can cross‑check the 12 A rating, MGP interface needs, and braking resistor so the new unit drops in with minimal rewiring.
