Product Description:

The CDB01.1C-SE-ENS-ENS-ENS-NNN-S2-S-NN-FW control card is built by Bosch Rexroth Indramat for the CDB Control Units series. As a modular control component, it slots into compatible drive stacks and supervises motion axes, fieldbus links, and machine safety channels inside automated cells. By combining high-speed encoder evaluation with configurable I/O, the board supplies the deterministic timing that servo amplifiers and PLC layers require during coordinated machine operation. It is suited to systems where several devices must exchange commands and status data without delays that would disturb axis synchronization.

It accepts differential 5 V TTL command streams up to 400 kHz, allowing pulse-train positioning without loss of edge integrity. The analog interface is tuned for precision, and a front-end impedance of 160 kΩ minimizes loading on process sensors. An input granularity of 1.23 mV/inc permits fine velocity trimming, while command values generated internally can also be sent to external drives with an output resolution of 19.5 mV/inc. Core logic and encoder slots draw only 9 W at idle, which helps limit heat buildup inside the cabinet. Real-time coordination with neighboring devices is carried on the fiber-optic bus identified as SERCOS II, so parameter sets and cyclic data move with sub-millisecond latency. This arrangement supports synchronized communication between the control layer and connected drive modules during motion and fault handling.

The encoder backplanes are supplied with 11.6 V rails, and a per-slot budget of 500 mA supports LED feedback and sensor power without external regulators. When service tools must bypass the optical network, the board exposes an RS-232 port that sustains diagnostic communication at 115 kBaud. Additional functions include 6 A inrush management, a 1 A DC relay contact, 60 ms pulse stretching, and Safe Motion technology. These functions support interlocks, status signaling, and controlled stopping while keeping the control layout compact.
