Product Description:

The DDS02.1-W050-DS56-00-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and supplied within the DDS Drive Controllers series. It serves as the power and control interface between a servo motor and the plant’s higher-level motion system. The drive regulates current and velocity loops so automated machinery receives precise closed-loop actuation in multi-axis production lines and material-handling equipment. It is intended for high-speed applications where repeatable axis response is required during positioning and continuous motion.

This controller exchanges real-time setpoints and status data through the SERCOS interface, allowing deterministic communication with CNCs and PLCs. Its continuous output capability is rated at 50 A, which is the maximum motor phase current it can regulate during continuous operation without thermal overload. Heat generated by the switching devices is removed by internal air cooling, which moves cabinet air across the heat sink and removes the need for external ducting. Rotor position is tracked with digital servo feedback, enabling high-resolution speed control and electronic commutation. Electrical parts are housed behind an IP20 barrier, so the unit is intended for installation inside a protected enclosure.

The ambient operating range is 0 to 45 °C, so the surrounding cabinet must stay within that limit during continuous duty. For long-term storage, the electronics tolerate -30 to 85 °C when unpowered, which helps protect the unit during seasonal temperature swings. Installation heights up to 1000 m are permitted without derating, which suits most factory floors and elevated conveyor structures. The unit belongs to Line 02 and is delivered as Version 1. These conditions match typical indoor industrial installations where stable cabinet ventilation is available.
