Description
DKC02.3-100-7-FW is a Bosch Rexroth Indramat ECODRIVE03 drive controller with a SERCOS interface for fiber-optic command communication.

The 100 A, voltage-code 7 power section operates from 1 × AC or 3 × AC 200–480 V mains, supports 4 or 8 kHz switching, and uses internal forced-air cooling with an airflow requirement of approximately 48 m³/h.

For replacement, preserve the SERCOS ring order, fiber transmit/receive direction, drive address, optical power, data rate, and separately selected application firmware before restoring the validated machine 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.
What must match before DKC02.3-100-7-FW is inserted into an existing SERCOS ring?
Confirm the drive address, transmit and receive fiber direction, optical power setting, SERCOS data rate and phase parameters, controller project, ring order and the separately selected application firmware.
Can DKC02.3-100-7-FW directly replace the 40 A DKC02.3-040-7-FW?
No. The 100 A unit has different dimensions, current capability, DC-bus capacitance, cooling and braking data. The cabinet, protection, motor, bus group and parameters require an engineering review.
Why can the SERCOS ring remain below the operating phase after installing DKC02.3-100-7-FW?
Check reversed or open fibers, a duplicate address, incorrect optical power or data rate, wrong ring order, firmware mismatch and a controller project that still expects the previous drive identity.
What DC-bus and braking checks are specific to the 100 A DKC02.3-100-7-FW power class?
Verify bus polarity, precharge, grouping, capacitance, branch protection, regeneration duty, the 120 kW peak and 0.5 kW continuous bleeder limits and the internal 6-ohm dynamic-brake path.
Is application firmware supplied by the FW suffix of DKC02.3-100-7-FW?
No. FW is a placeholder for separately selected firmware. The exact firmware type and release must match the SERCOS project, motor and machine function.
Can application firmware from a DKC02.3-040-7-FW unit be reused in DKC02.3-100-7-FW?
Only when Bosch Rexroth documents the firmware release and application package as compatible with the 100 A hardware, motor and machine configuration. Verify power-section recognition, current scaling, option support and the approved parameter file before enabling torque.
Why can the SERCOS link become intermittent after DKC02.3-100-7-FW reaches the operating phase?
Inspect the fiber connectors for contamination or damage, confirm transmitter-to-receiver routing, observe the permitted bend radius, secure the cable against vibration and verify optical attenuation. A marginal optical path may initialize successfully but fail during machine operation.
