Product Description:

The Bosch Rexroth Indramat CDB01.1C-S3-EN2-EN2-ENS-ENS-S2-S-NN-FW is a plug-in control unit within the CDB Control Units series. It occupies the command slot of a modular drive controller and provides axis processing, encoder interfacing, and field communication for multi-axis automation. Multiple feedback channels let the module translate high-resolution position signals into drive commands that regulate torque, velocity, and position in electric servo systems used on packaging machines, material handling lines, and other factory equipment. Because the control electronics are integrated on a removable card, the unit fits compact drive assemblies where centralized cabinet space is limited.

The unit can coordinate 2 independent drive axes, which suits applications that need synchronized motion from a single control platform. Its standby consumption is limited to 9 W, keeping idle heat generation low inside the cabinet. When the controller is energized, an inrush of 6 A for up to 60 ms must be accommodated by the supply. Diagnostic access is available through an RS-232 maintenance port that supports transfer rates up to 115 kBaud across cable runs of 15 m. For synchronous drive networks, the S3 cross-communication interface operates as a slave node on an RJ-45 8-pin connector, allowing peer messaging without an added gateway.

Encoder processing is divided between separate supply sections. The En2 channel sources 5.0 VDC at up to 350 mA, supports square-wave feedback frequencies to 1000 kHz, and allows sense-line compensation on cables up to 75 m. The Ens channel delivers 11.6 VDC with a drive budget of 500 mA and accepts TTL inputs to 400 kHz for resolver-to-digital and multi-turn feedback devices. A dedicated S2 terminal can also power external sensors at 1.6 A, which helps keep peripheral loads separate from the main drive electronics during peak motion demand.
