Product Description:

The DDS02.1-W200-DS46-02-FW is a modular servo drive manufactured by Bosch Rexroth Indramat and supplied in the DDS Drive Controllers series. As a closed-loop power stage, it mounts in multi-axis automation cabinets to convert a shared DC bus into controlled three-phase output for synchronous or induction servomotors. Within an industrial cell, it links high-level motion commands to the mechanical load and delivers coordinated speed, torque, and position regulation for conveyors, pick-and-place gantries, and packaging machinery where deterministic response is required. This arrangement lets the controller serve as the electrical interface between the supply module and the motor while supporting coordinated axis behavior across automated equipment.

The output section is rated at 200 A, so the drive can energize high-torque axes without thermal derating during continuous duty. All motion telegrams, diagnostic bits, and parameter sets are exchanged over a SERCOS interface, providing deterministic cycle times that allow multiple axes to stay synchronized within microseconds. Thermal management is handled by internal air cooling; cabinet air is pulled through the heat sink, eliminating the need for external ducting while maintaining permissible component temperatures. Position data from the motor is returned through digital servo feedback, enabling the current regulator to correct torque within each control cycle and minimize following error. Because feedback is processed inside the controller, speed and position loops can be closed directly in the drive rather than in an external module. The unit is a Digital AC Servo Drive Controller with the power electronics, signal processing, and axis parameter memory integrated into a single 300 mm Euro-card format module.

The drive belongs to Line 02 and is Version 1. The line and version codes identify the product generation used for this controller. Application-specific functions such as velocity feedforward, commutation tables, and safety shutdown routines reside in removable PROM modules. Keeping these functions in PROM modules allows the controller to be matched to the target machine program without changing the base power stage.
