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.
Can DKC03.3-040-7-FW directly replace DKC03.1-040-7-FW because both use PROFIBUS-DP?
No. DKC03.3-040-7-FW belongs to the ECODRIVE03 platform, while DKC03.1-040-7-FW belongs to the earlier ECODRIVE generation. The .3 unit uses the X30 PROFIBUS interface and a different programming-module, firmware, power and connector architecture. Match the complete controller type, firmware family, PLC device project, connector assignments, supply and DC-bus design, motor and feedback system, parameters and mechanical installation before migration.
What must be matched at the PROFIBUS connection of DKC03.3-040-7-FW?
Match the address set by switches S2 and S3, the X30 A/B conductor assignment, connector termination and shield connection, and the permitted cable length for the master’s baud rate. Termination must be active only at the first and last physical stations. The PLC device or GSD entry, cyclic input and output lengths, command/status mapping and the complete FWA-ECODR3-FGP firmware type and release must also match the approved project.
Why can DKC03.3-040-7-FW exchange diagnostics but not the expected process words?
PROFIBUS can be online even when the PLC contains the wrong device module, telegram profile or cyclic data length. Confirm that the project uses the ECODRIVE03 fieldbus definition rather than an older DKC03.1 PDP configuration. Compare the GSD or device entry, input and output lengths, byte and word order, command/status allocation, parameterized fieldbus profile and installed FGP firmware release.
Can DKC03.3-040-7-FW be added to a common DC bus as an unplanned extra axis?
No. Bosch Rexroth treats 040-class controllers on a common DC bus as an engineered group-supply arrangement using the required mains-contactor, control-voltage and ready-contact wiring. Before adding an axis, recalculate connected mains power, permissible continuous and peak DC-bus power, regenerative energy, bus capacitance, charging current, bleeder capacity and protection. The resulting controller and auxiliary-module combination must remain within the documented topology limits.
Why can the PDP firmware from DKC03.1-040-7-FW not be reused in DKC03.3-040-7-FW?
DKC03.1 belongs to the earlier ECODRIVE platform and uses the FWA-ECODRV-PDP firmware architecture. DKC03.3 belongs to ECODRIVE03 and uses the FWA-ECODR3-FGP fieldbus firmware family. The programming-module structure, parameter set and PLC device profile must match the .3 controller and its exact FGP release.
Why can the H30–H33 indications on DKC03.3-040-7-FW differ from the original unit even when the PROFIBUS address is correct?
The detailed meanings of H30–H33 are defined by the installed firmware, not solely by the hardware address. Compare the complete FGP firmware type and release, PLC device profile and current PROFIBUS state with the original axis. A correct S2/S3 address does not prove that the cyclic module definition or firmware diagnostic mapping is the same.
How should the PROFIBUS and motion sides of DKC03.3-040-7-FW be recommissioned together?
Restore the approved ECODRIVE03 FGP project and verify the slave address, device entry, cyclic data lengths and command/status word definitions before enabling motion. Confirm stable PROFIBUS diagnostics and prove the PLC transitions through halt, ready and enable states correctly. With active bus communication, the hardwired AH and RF inputs are not effective, so the corresponding PLC command-word control must be validated. Then test emergency-stop behavior, direction and feedback at restricted torque and speed, followed by the configured positioning or motion functions, travel limits, braking and the complete production cycle.
