More Information

Overview Manuals PROFIBUS Project Mains & Bleeder 24 V & Brake Application
  • Match the PROFIBUS-DP station project to the DKC03.1 hardware and PDP firmware release
  • Size sustained axis duty from 16 A at 4 kHz or 12.5 A at 8 kHz, not the 40 A peak class
  • Account for the integrated mains and bleeder section when replacing this .1-generation controller

DKC03.1-040-7-FW is a Bosch Rexroth/Indramat ECODRIVE controller with an integrated mains power section and PROFIBUS-DP command communication.

The exact model accepts three-phase 380–480 V AC, provides a 40 A rated and peak current class, and has documented continuous current of 16 A at 4 kHz or 12.5 A at 8 kHz. Its application firmware is ordered separately; the documented PROFIBUS firmware family is FWA-ECODRV-PDP-03VRS-MS.

Before exchange, preserve the PROFIBUS station assignment and PLC data map, verify the firmware release, and check the mains, bleeder, motor-feedback, brake and 24 V control connections against the original axis record.

Availability, condition, price, and shipping time for DKC03.1-040-7-FW are confirmed during quotation.

  • Restore the station address and PLC module definition used by the original DKC03.1 axis
  • Compare cyclic input/output lengths and command/status word order before enabling motion
  • Use the PDP firmware type and release recorded for the machine project
  • Supply the controller from three-phase 380–480 V AC within the documented ±10% range
  • Check the integrated 10 kW peak / 0.15 kW continuous bleeder against regenerated axis energy
  • Verify branch protection, protective earth and the 500–800 V DC-bus operating range
  • Provide 19.2–28.8 V DC control power and include the documented 0.7 A controller load
  • Keep the holding-brake supply within 21.6–26.4 V and match its current to the connected MKD motor
  • Follow the documented DKC03.1 control-voltage switching arrangement before enabling the axis
  • PROFIBUS-DP machine axes exchanging cyclic command and status words with a PLC
  • Stored-positioning-block sequences selected through the DKC03.1 PROFIBUS interface
  • Handling and mounting stations engineered around the DKC03.1 controller project
Description
DKC03.1-040-7-FW is a Bosch Rexroth ECODRIVE DKC drive controller with a 40 A current class and voltage code 7.

Bosch Rexroth type-code documentation identifies FW as a separately ordered firmware identity. The installed firmware type and release must match the approved machine project.

Before replacement, record the complete controller type code, firmware identity, SERCOS configuration, motor feedback, mains supply and approved drive parameters.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which PROFIBUS project data must agree with DKC03.1-040-7-FW?
Match the physical PROFIBUS slave address, the PLC’s GSD or device-project entry, the master-selected baud rate and permitted segment layout, and the cyclic drive-control and drive-status word mapping. The positioning-block selection data and the complete FWA-ECODRV-PDP-03VRS-MS firmware type and release must also agree with the approved machine project.
Can DKC03.1-040-7-FW use positioning blocks stored for a different DKC interface variant?
Do not load them as an unverified complete block set. DKC03.1-040-7-FW can store up to 64 positioning blocks selected through PROFIBUS-DP, but their parameter structure must match the PDP firmware. Before migration, verify position units and scaling, homing data, travel modes, velocity and acceleration values, feedrate override, sensor conditions, travel limits, motor and feedback data. Use the approved DKC03.1 machine backup whenever available.
Why can DKC03.1-040-7-FW power up while the PROFIBUS master reports it offline?
First verify that the 24 V control supply is present at X4; the drive cannot communicate through PROFIBUS while its control voltage is off. Then check the front-panel slave address, H3 PROFIBUS indication, PLC project entry, X10 connector and A/B conductor polarity. Termination must be active only at the two physical ends of the segment, with the cable shield contacting the connector’s metal guide. Also verify cable length against the master’s baud rate and confirm the installed PDP firmware type and release.
Which application firmware belongs to DKC03.1-040-7-FW?
Bosch Rexroth specifies FWA-ECODRV-PDP-03VRS-MS for DKC03.1-040-7-FW. Match the complete release shown on the firmware plate and used by the PLC project. ASE, SSE and ECODR3-FGP firmware identify other command-interface or controller generations and are not substitutes.
Can the PROFIBUS connector on DKC03.1-040-7-FW be moved without preserving bus termination?
No. The PROFIBUS connector contains switchable termination. Termination must be on at the first and last physical stations and off at all intermediate stations. Before moving the connector, document the incoming and outgoing A/B conductors, termination-switch position and shield contact; an incorrect replacement can disconnect every downstream device.
Why can a restored positioning block on DKC03.1-040-7-FW stop at the wrong machine position?
DKC03.1-040-7-FW can store up to 64 positioning blocks, but their targets depend on the restored position units, gear or feed constant, reference offset and motor-feedback configuration. Also compare the block’s absolute or relative travel mode, sensor condition, feedrate override and software travel limits before changing the target value itself.
How should DKC03.1-040-7-FW be commissioned with a PLC after replacement?
Following the approved machine safety procedure and with motion inhibited, apply the 24 V control supply first and confirm status-word bits 7, 6 and 5 indicate 011. Apply mains power with the drive command stopped and confirm 101, then issue drive enable only after the required conditions are present and confirm 111. Verify the PLC control and status words, PROFIBUS diagnostics and emergency-stop response before motion. Establish the reference position, test direction at restricted speed and torque, and then validate every positioning block used by the production program, including limits, braking and sensor-dependent sequences.
