Description
DKC03.3-100-7-FW is a Bosch Rexroth Indramat ECODRIVE03 drive controller with a PROFIBUS-DP command interface for PLC-integrated motion systems.

The 100 A, voltage-code 7 unit accepts 1 × AC or 3 × AC 200–480 V mains, supports 4 or 8 kHz switching, and provides an internal 6 Ω dynamic-brake path with forced-air cooling.

For replacement, retain the PROFIBUS station address, connector direction, bus termination, shield bonding, GSD and I/O mapping, and separately selected application firmware before motion is enabled.

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 DKC03.3-100-7-FW?
Match the station address, connector direction, end termination, baud-rate cable limits, shield bonding, GSD or PLC project entry, cyclic I/O lengths, command/status mapping and application firmware.
Can DKC03.3-100-7-FW replace DKC03.3-040-7-FW without cabinet and power changes?
No. The 100 A controller is wider and has different current, cooling, DC-bus capacitance and braking data. Recheck mounting, fusing, wiring, motor duty, bus grouping and the saved drive project.
Why can DKC03.3-100-7-FW appear online while the PLC receives the wrong process words?
The physical bus can be healthy while the configured module, I/O lengths, word order or command/status allocation is wrong. Compare the approved PLC project and firmware function with the installed drive.
What should be checked when downstream PROFIBUS nodes disappear after replacing DKC03.3-100-7-FW?
Confirm whether the drive is an end station, both connector directions, switchable termination, cable continuity, shield bonding, address uniqueness and that no unterminated spur was introduced.
Can the PROFIBUS address of DKC03.3-100-7-FW be changed without updating the PLC project?
No. The address configured for the drive must match the PLC hardware configuration and must remain unique on the segment. Apply the change using the documented procedure, restart communication when required and verify that the master reconnects to the intended drive.
Why can PROFIBUS communication with DKC03.3-100-7-FW become unstable only when the motor is enabled?
Motor-output interference may be coupling into the bus cable. Check PROFIBUS shielding and connector grounding, protective-earth bonding, cable separation from motor conductors, termination, routing and cabinet equipotential bonding.
What should DKC03.3-100-7-FW do if PROFIBUS communication is lost during operation?
It must follow the approved communication-loss response defined by the PLC and drive configuration. Under a controlled test, verify the resulting torque or stop behavior, fault indication, PLC alarm, recovery sequence and prevention of an unexpected automatic restart.
