Product Description:
The DDS02.1-W025-DS04-03-FW is a unit produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed in multi-axis cabinets, it governs torque and speed commands sent to synchronous servomotors, allowing coordinated positioning tasks within automated production lines. It is used in machine tools, printing presses, and material-handling gantries where several axes must respond in a coordinated way. Its role is to regulate motor behavior within compact servo systems that use a modular rack layout.
The device occupies a single slot in the modular rack and connects to higher-level PLCs over the SERCOS interface, so real-time setpoint data and diagnostic words travel on a fiber-optic ring with deterministic timing. Continuous current capacity reaches 25 A, matching drives for medium-frame motors that demand rapid acceleration under load. Feedback from the motor arrives as digital servo feedback, enabling fine commutation without analog drift. This feedback arrangement lets the controller process rotor position and velocity information directly inside the drive. Thermal management is handled by internal air cooling, so cabinet air moves through the heat sink without an external blower. The current loops and pulse-width modulation are intended for digital AC servo operation rather than simple stepping or scalar voltage control.
The controller relies on a host supply module for DC bus power instead of carrying its own supply section. Within the DDS architecture, the unit is part of Line 02 and is Version 1. These identifiers place it within an early generation of the product line. Operating data is stored in non-volatile memory, so settings remain available after power cycling. Because the power section is shared at the rack level, the module remains focused on control and regulation functions for the connected motor. This arrangement supports compact cabinet layouts while preserving the coordinated servo control expected in modular automation systems.
