        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.
        VIEW ALL FAQS
        What must match before DKC02.1-040-7-FW is inserted into an existing SERCOS ring?
        Confirm the SERCOS address set by switches S2 and S3, the X10 transmit and X11 receive fiber routing, the S4 data-rate and transmitter-power settings, and the fiber connectors and cable type. The master project, cyclic telegram configuration and complete FWA-ECODRV-SSE firmware type and release must also match the original axis.
        Can DKC02.1-040-7-FW replace a parallel- or PROFIBUS-interface DKC controller?
        No. DKC02.1-040-7-FW is the SERCOS fiber-optic variant. A parallel- or PROFIBUS-interface controller uses different command hardware, cabling, controller configuration and firmware. Substitution requires an engineered control-system conversion and is not a direct replacement.
        Are the SERCOS fiber components and application firmware included with DKC02.1-040-7-FW?
        Not under the controller identity alone. Bosch Rexroth states that the fiber-optic plugs and cables for X10 and X11 are not included with the drive controller. The function-defining firmware also has its own order number and must be selected separately. Verify the complete firmware type and release, fiber connectors and cable lengths against the machine bill of material.
        Why can the SERCOS ring remain in phase zero after fitting DKC02.1-040-7-FW?
        Check that X10 Tx feeds the next device’s receive connection and that the complete fiber ring returns to the master without an open or reversed link. Verify that the S2/S3 address is unique and matches the master project, S4/1 is set to the master’s 2 or 4 Mbit/s data rate, and S4/2–S4/3 provide suitable transmitter power for the installed fiber length. Also inspect the connectors for contamination, damage or excessive cable bending.
        What happens if the SERCOS address on DKC02.1-040-7-FW duplicates another axis?
        The master cannot reliably assign the intended drive to its cyclic telegrams, so the ring may fail to reach the operating phase or may report an address or configuration error. Restore the documented unique address from 1 to 99, confirm the physical ring order and restart communication before enabling motion.
        Why can DKC02.1-040-7-FW communicate at 2 Mbit/s but become unstable after the SERCOS master is changed to 4 Mbit/s?
        Switch S4/1 on DKC02.1-040-7-FW must match the master’s SERCOS data rate. After selecting 4 Mbit/s, also verify the permitted fiber length and attenuation, connector condition and the S4/2–S4/3 transmitter-power setting. Excessive transmitter power is not a substitute for damaged, contaminated or incorrectly routed fiber.
        Why can DKC02.1-040-7-FW reach the SERCOS operating phase but report the wrong axis position?
        Reaching the operating phase confirms communication, not the axis reference or feedback configuration. Verify that the original motor-feedback parameters, position polarity, mechanical scaling and homing data were restored. If an external measuring system is connected to X2, confirm its signal type, direction and reference relationship before comparing the SERCOS actual-position value with the machine coordinate.
