The RZP Option Modules from Bosch Rexroth Indramat comprise a modular option-card series for the RD 500 drive family, designed to extend converter functionality through add-on modules installed in control-module slots 1 and 2.
The series includes communication and interface expansions such as Interbus S, CANopen, Profibus DP, SERCOS, SynchroLink, and peer-to-peer coupling, along with application-specific options for incremental encoder emulation, external encoder input, and extended control terminal strips. These modules communicate with the drive control card through the process-data interface, with the selected slot determining whether the firmware addresses the option through the SS2 or SS4 serial interface path. The platform is designed to support both factory-installed and retrofit configurations, with defined card-combination rules for RD51 and RD52 units and parameter settings required according to the installed module type and slot location. Overall, the RZP series is intended to add communication, feedback, synchronization, and terminal-level functionality to RD 500 converters without changing the base drive architecture.
