Product Description:
Bosch Rexroth Indramat manufactures the DDS02.1-W150-DS04-02 as part of the DDS Drive Controllers series. This digital AC servo drive controller links a supply module to a synchronous or induction motor so that motion profiles sent by higher-level automation systems can be executed with closed-loop precision. In a multi-axis cabinet, it serves as the power conversion stage between the DC bus and the motor windings. This arrangement lets the drive respond quickly to command changes during acceleration, deceleration, and positioning. Within an installation, it occupies the drive position denoted as Line 02 and is intended for use in cabinets that comply with industrial control panel standards.
The unit exchanges real-time setpoints and status data with the master control through a SERCOS interface. Continuous motor current is limited to 150 A, which gives the power stage the current capacity needed for normal servo operation. Component ingress protection is rated at IP20, which blocks contact with larger solid objects while leaving environmental sealing to the cabinet. Thermal energy is removed by air from inside the control cabinet, so cabinet airflow has a direct effect on cooling. Rotor position and velocity are returned to the drive through digital servo feedback, allowing closed-loop control without a separate converter. The permissible ambient operating range is 0 – 45 °C, so internal cabinet temperature must stay within that span during use.
For storage, the electronics can withstand temperatures of -30 – 85 °C, which helps protect the unit during nonoperating periods in unconditioned spaces. This storage range applies when the unit is powered down rather than operating in a machine. Installation is approved up to 1000 m above sea level, because reduced air density above that height can lower cooling effectiveness and insulation margin. Cabinet elevation and ambient temperature both affect how effectively heat is removed during operation. The unit is Version 1, and that revision is used on the DDS02.1 platform with a shared DC bus and a SERCOS ring.
