DKC11.3-040-7-FW is a Bosch Rexroth ecodrive servo drive controller in the ECODRIVE03 DKC family.

Bosch Rexroth Indramat DKC11.3-040-7-FW is a 40 A ECODRIVE servo drive controller with RS232/RS485 and analog interface, integrated mains power section and separately selected firmware. The complete type code identifies the DKC hardware series, design version, 40 A current class and voltage code 7; the FW suffix means that application firmware is a separate ordered identity and must match the machine project.

Before installation or replacement, verify the complete nameplate, firmware, command interface, mains and DC-bus design, motor, wiring and approved commissioning file.

Availability, condition, price, and shipping time for DKC11.3-040-7-FW are confirmed during quotation.

  • Match RS232 or RS485 protocol, address and framing
  • Keep serial termination, shield bonding and cable topology unchanged
  • Verify mains voltage, protective earth and branch protection
  • Review DC-bus sharing, bleeder energy and precharge
  • Match motor, feedback, brake and switching-frequency limits
  • Check analog zero and serial diagnostics with motion inhibited
  • Prove direction, feedback and command scaling at low load
  • Validate braking, current limits, noise immunity and full duty
  • Analog-command machine-tool servo axes
  • RS485-supervised handling and mounting systems
  • Analog-command packaging-machine motion axes
Description
DKC11.3-040-7-FW is an ECODRIVE03 DKC drive controller whose complete code identifies a 40 A, voltage-category-7 hardware unit; its function-defining firmware is selected separately.

Use it only after confirming the required RS232/RS485 and analog-command configuration, firmware module, motor and feedback data, mains and DC-bus design, and saved parameters for the installed axis.

During replacement, preserve interface wiring and configuration, then prove safe drive operation under the approved commissioning procedure before returning the axis to service.

Technical notes
DKC11.3-040-7-FW is the drive-controller hardware identity; its firmware is a separate ordered item. Match the RS232/RS485 and analog interface, motor/feedback system, mains design and saved parameters before replacement.

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.
How should the analog command for DKC11.3-040-7-FW be matched to an existing machine?
Record the command-voltage range, reference potential, polarity, scaling, offset, enable logic and shield termination. Reproduce the approved wiring and parameter scaling before applying a motion command.
Can the RS485 connection on DKC11.3-040-7-FW replace a PROFIBUS-DP command interface?
No. The serial RS485 interface on DKC11.3-040-7-FW and PROFIBUS-DP use different communication architectures and are not interchangeable. Before replacing a drive, confirm the machine’s command interface, controller type, interface hardware, PLC project, firmware and parameter set. An RS485 adapter alone cannot convert this model into a PROFIBUS-DP drive.
Why might DKC11.3-040-7-FW enable but drift with a zero command?
Check analog offset, reference-ground differences, shield bonding, noise pickup, input scaling, integrator settings and whether the restored parameter file belongs to this axis and motor.
What must be checked before connecting DKC11.3-040-7-FW to an existing RS485 multidrop link?
Confirm the supported serial protocol, cable topology, termination, address, baud rate, command format and controller configuration specified for the complete drive and its selected firmware. Do not apply serial settings from another DKC variant without verifying the installed hardware and project.
Is the correct application firmware automatically included with DKC11.3-040-7-FW?
Do not assume so. Bosch Rexroth states that the function-defining firmware must be ordered separately; the FW suffix does not identify the required firmware release. Before installation, verify the firmware module’s complete FWA code and version and confirm that the machine-specific parameter set is available.
Can a parameter file from another DKC11.3-040-7-FW be loaded directly into this drive?
Not automatically. First confirm the application firmware, command-source configuration, motor and feedback type, brake control, analog scaling, current limits and machine-specific safety settings. Back up the installed data before transferring only the approved parameter set.
Can DKC11.3-040-7-FW be used with any motor whose current is below the drive rating?
No. Motor selection must also match the supported Rexroth motor and feedback combination, voltage, continuous and peak duty, brake arrangement, temperature monitoring, firmware function and approved motor parameters. Current rating alone does not establish compatibility.
