Product Description:

The DDS02.1-W150-DL43-01-FW belongs to the DDS Drive Controllers series manufactured by Bosch Rexroth Indramat. It is a digital AC servo drive controller that provides closed-loop regulation between an Indramat supply module and a synchronous or induction motor, allowing precise torque and velocity management in automated machinery and material-handling cells. Command data are accepted through a single-axis position control interface, giving the application a direct channel for coordinate moves and homing routines. This arrangement suits machines that need repeatable axis motion during indexing, transfer, and other controlled movement sequences. The controller supports applications where stable speed control must be maintained while the load changes during operation.

The unit delivers a continuous output of 150 A, so the connected motor can receive high surge currents during rapid acceleration without exceeding the controller’s thermal limits. Feedback from the motor is returned via digital servo feedback, which supplies real-time position information for tight following error control. This closed-loop arrangement helps the controller correct deviations caused by changing load conditions or rapid speed transitions. Heat generated by the power electronics is removed through internal air cooling; cabinet air is drawn across the heatsink without requiring external ducting. The unit is part of Line 02, and motion parameter blocks use Function ID 01 for compatibility across the product family.

The drive uses a code-matched separate firmware subitem, so motion libraries and diagnostics align with the installed hardware. The hardware build is tagged as version 1, indicating the first released revision of the W150 power stage. The device mounts on a common backplane and can share a fiber-optic SERCOS loop with other DDS drives, allowing coordinated multi-axis operation without an added gateway module. This layout supports rack-based systems where several axes exchange control data over the same communication path. It can be used in multi-axis cabinets where synchronized motion and centralized control are required across several drive positions.
