Product Description:

Bosch Rexroth Indramat builds the CDB01.1C-ET-ENS-EN2-NNN-ENS-S2-S-NN-FW as part of the CDB Control Units series. Installed in an IndraDrive controller rack, this control section governs up to two servo axes, stores parameters, and handles real-time fieldbus traffic for coordinated motion. Its role in automation cells is to translate higher-level machine commands into drive-level setpoints while monitoring feedback and activating embedded safety routines during operation. Because it resides in the controller rack, it centralizes motion control, feedback processing, and safety response functions in one removable control section.

The unit communicates over Multi-Ethernet, allowing it to operate on SERCOS over Ethernet, EtherNet/IP, or PROFINET without extra option cards. Incoming mains energization produces a base inrush of 6 A, and once initialized the electronics draw only 9 W, which helps limit heat inside the cabinet. Network wiring attaches to a port rated for 100Base-TX, while legacy devices can still be serviced through an RS-232 diagnostic connector. A single-line display on the detachable control panel presents status codes, and an MMC card slot provides removable parameter memory. These interface options provide both network connectivity and direct local access for diagnostics and removable storage. The axis logic runs in a 12-bit analog-to-digital section labeled ENS, which captures reference voltages with a maximum pulse width allowance of 60 ms.

Encoder handling is divided between the ENS and EN2 blocks. The EN2 channel supplies 5 V to incremental sensors and requires a dedicated sense pair for cable-drop compensation, which helps maintain the intended supply voltage at the encoder. The ENS interface offers 12 V for absolute encoders and accepts TTL feedback up to 400 kHz. Integrated safety technology identified as Safe Motion lets the controller issue controlled stops and speed-limited operation without external relays. Relay outputs inside the module are rated at DC 24 V and 1 A for brake release or actuator signaling.
