Product Description:

The DDS02.2-W200-BE04-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Intended for multi-axis automation, the unit receives setpoints from higher-level motion controls and regulates motor current so that coupled servomotors follow commanded torque, speed, or position profiles. It serves as the power and control stage between the DC bus and the motor, allowing coordinated axis operation in automated equipment. This arrangement lets a central control system coordinate multiple axes with repeatable response during indexing, positioning, and speed-controlled motion.

The drive exchanges process data through the SERCOS interface, enabling synchronous communication with drives, I/O, and PLCs across a fiber-optic ring. Its rated current is 200 A, so the connected motor must remain within that output limit during operation. Thermal energy is removed by internal air cooling, which requires cabinet airflow to pass through the heat sink rather than use an external blower. The housing has an IP20 rating, so the controller must be installed in a closed panel away from conductive dust. Operation is permitted from 0 to 45 °C, allowing full output in standard factory conditions. The controller is part of Line 02 and is Version 2.

For storage or transport, the electronics remain stable from -30 to 85 °C, which helps protect internal components during non-operating periods. Elevation is limited to 1000 m, because higher altitudes reduce cooling effectiveness and electrical clearance margins. On the feedback side, the drive processes both digital servo feedback and resolver feedback, so it can operate with motors that use either encoder-based or resolver-based feedback devices. These feedback signals close the current and velocity loops inside the controller, while position values are transmitted to the SERCOS master at the configured cycle time. Because the unit accepts both feedback types, the same controller can be used with machines that have different motor feedback systems.
