Product Description:

The DDS02.1-A150-DG01-00 drive controller is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. It functions as a digital AC servo drive controller that regulates three-phase synchronous or induction motors in automated machinery. By converting command signals from the main motion controller into controlled current and voltage, the unit closes the torque and speed loops for precise axis positioning in packaging lines, material-handling gantries, and assembly stations. This control process helps the motor respond accurately to changing loads while maintaining stable motion through repeated machine cycles. Because the drive handles both command execution and motor regulation, it serves as the main control stage between the machine controller and the connected motor.

Its power section is sized for a continuous output of 150 A, so the drive can energize medium-to-large servo motors without thermal current limiting during normal operation. Thermal management relies on air drawn from outside the control cabinet, a cooling method that helps reduce heat buildup inside the enclosure during extended duty. The electronics have an IP20 rating, which supports installation inside electrical panels while protecting against accidental contact with live parts. Permissible ambient conditions range from 0 to 45 °C, making the unit suitable for operation in typical industrial spaces. The drive can be installed at elevations up to 1000 m above sea level without additional derating.

Signal handling is managed through the integrated digital servo feedback interface, allowing high-resolution position data exchange between compatible motors and the controller’s regulation circuits. This feedback path supports accurate motor control during speed changes and position corrections. When the machine is powered down, the unit can be stored at temperatures from -30 to 85 °C, which helps protect it during transport and storage. Those storage limits apply while the controller remains unpowered. Internal parameter sets are assigned to Function ID 01, so the drive uses the matching parameter structure for this configuration. The unit is built as Version 1, which identifies the released product revision for this controller.
