Product Description:
The CDB01.1C-SE-ENS-ENS-EN2-EN2-S2-S-NN-FW is a drive controller insert produced by Bosch Rexroth Indramat for the modular CDB Control Units series. Installed inside an IndraDrive power section, the board coordinates feedback, motion functions, and fieldbus traffic for multi-axis automation. It acts as the interface between the servo inverter and higher-level machine logic, converting command telegrams into precise current and position control tasks in production lines, packaging machines, or material-handling cells.
Real-time regulation is supported by a current loop that closes every 125 µs, giving the drive quick torque response under load swings. Host connection uses Sercos II fiber or copper rings for deterministic exchange of set points and status. Two independent analog outputs mean that 2 proportional signals can be wired to external instruments, while 4 software-selectable I/O points cover sensors or actuators that do not require separate PLC cards. Functional safety is addressed by the integrated Safe Motion (SIL2 / Cat. 3 PL d) monitoring circuit, enabling certified stop and speed limits. Feedback flexibility comes from the 2x ENS plus 2x EN2 encoder arrangement, and fast input channels accept command pulses up to 60 ms wide. A service computer connects through the 8-pin Mini-DIN RS-232 port for local setup and diagnostics.
The insert combines low control-power demand with a compact form factor for cabinet installation. The base circuit draws a maximum inrush of 6 A and maintains its logic with only 9 W of steady consumption, which helps limit cabinet heat. Sensor groups receive isolated supplies of 5 V for EN2 transducers and 12 V for ENS encoders, eliminating the need for external regulators. The card occupies 49.5 mm in width, 103 mm in depth, and 322.6 mm in height, allowing direct stacking with other IndraDrive modules. Its dimensions fit standard module spacing and leave clearance for airflow without additional spacers.
