Product Short Description
Product Name: Bosch Rexroth Indramat DKCxx EcoDrive03 Drive Controller Series (Generic DKC Platform Reference)
Product Overview: The DKCxx designation refers to the complete family of DKC EcoDrive03 digital servo drive controllers. The series spans multiple hardware generations (DKC01 through DKC22) and current ratings from 4 A to 200 A continuous. All units share the EcoDrive03 architecture with modular firmware and option card expansion.
Description

- DKC05.x – DKC06.x: Mid-range current variants
- DKC10.x – DKC11.x: High-current 100–200 A frames with internal blower
- DKC21.x – DKC22.x: Highest power density variants
Common Technical Specifications:
- DC-Bus Nominal Voltage: 700 V
- Input Voltage: 3×400–480 VAC (±10%), 50–60 Hz
- Control Voltage: 24 V DC
- Protection Class: IP20
- Device Height: 360 mm; Depth: 261 mm
- Width: 65 mm (040) / 105 mm (040–100) / 230 mm (200)
- Pollution Degree: 2 (UL)
- Operating Temperature: 45 °C (nominal) / 55 °C (reduced)
- UL Listing: UL 508 C; CSA C22.2 No. 14-05
Functional Features (across series):
- Up to 32 position recipes via I/O option card
- DriveTop software programming over RS-232
- Multiple communication options: SERCOS, PROFIBUS, CANopen, Analog
- Internal fan or blower cooling depending on frame size
- Dynamic brake (Zks) resistor integrated
- Bidirectional motor control
Application Scenarios: Single- and multi-axis motion control across packaging, printing, CNC, assembly, material handling, and robotics.
Installation Requirements (common to all DKC frames):
- Top clearance: 150 mm minimum
- Bottom clearance: 80 mm minimum
- Maximum installation elevation: 1000 m
- Branch circuit protection fuse per UL guidelines
- 60/75 °C copper wire, class 1
- Control cabinet with IP20 or better
Usage Notes:
- Firmware is sold separately for all DKC units
- Communication mode defaults to SERCOS; analog requires option card
- Units within the same current class are generally hardware-interchangeable if firmware matches project file
- The DKC series is now in end-of-production lifecycle (as of 2026); successor platform is Bosch Rexroth IndraDrive C/M series
- All live parts exceed 50 V—strict safety compliance required
