Product Description:

The CSB01.1C-SE-ENS-NNN-NN-S-NN-FW is an axis controller produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. It installs in a multi-axis cabinet slot and coordinates servo drives while providing closed-loop processing, safety expansion, and a basic front display for industrial automation cells. By integrating motion logic and feedback evaluation on one card, the unit reduces wiring and keeps time-critical servo functions on the controller instead of the higher-level PLC. This arrangement supports synchronized axis operation in machines that need fast response to position and velocity feedback.

The controller’s logic electronics are supplied with 24 VDC, allowing it to share the same low-voltage rail that powers cabinet sensors and relays. The controller has 8 opto-isolated input channels that accept positioning triggers or safety signals. The board also has 3 transistor outputs for drive-ready, fault, or user-defined status flags. This mix of inputs and outputs supports straightforward connection of interlocks, permissives, and status reporting within the control cabinet. For encoders, the board distributes 11.6 VDC, matching SinCos and TTL feedback devices without external supplies. When power is applied, the circuitry draws an inrush current of 4.5 A for up to 110 ms before settling to its normal operating level.

The communication layer uses the real-time SERCOS protocol for deterministic telegram exchange with connected drives. That timing behavior suits coordinated motion networks where command and feedback updates must remain predictable. Physical transmission occurs over fiber-optic cabling, which improves immunity to electromagnetic noise inside welding cells or presses. Once running, the electronics draw only 8 W from the auxiliary supply, which helps keep cabinet heat dissipation low. The digital I/O follows IEC 61131 Type 1 signaling, and a single-line panel display permits quick parameter checks on the controller itself.
