Product Description:

The DDS02.1-A100-DS46-02-FW is a drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed in multi-axis automation cabinets, it converts setpoint data from a master motion bus into controlled three-phase output for an AC servo motor. In a coordinated system, it serves as the power stage between the control network and the motor so commanded speed and torque can be applied with repeatable response. The unit is part of Line 02 and uses design version 1, so it matches the mechanical and electrical format used by other DDS modules in the same platform.

This controller exchanges real-time commands and diagnostic data through a SERCOS interface, allowing deterministic communication over fiber-optic cabling. This arrangement supports synchronized operation when several axes share motion data through the same control architecture. Cooling uses air from outside the control cabinet, so heat is removed without adding that thermal load to the enclosure interior. The power section is rated for a continuous current of 100 A, which is the maximum continuous RMS load the drive can deliver to a connected motor. An enclosure classification of IP20 provides basic finger protection, so the unit must be installed inside a protective rack or cabinet. Continuous operation is permitted in an ambient range of 0 to 45 °C, which suits normal factory conditions.

The unit can be mounted at elevations up to 1000 m above sea level without output reduction. It also withstands storage temperatures from -30 to 85 °C when not in operation, allowing the controller to be stored or transported through a wide temperature range. Position and speed signals from the motor are returned through digital servo feedback, which supports closed-loop control with accurate response to load changes. This feedback path lets the controller monitor rotor position and motor speed directly during acceleration, deceleration, and steady-state operation. The operating software is ordered separately from the controller hardware.
