Product Description:

The CDB01.1C-ET-ENS-ENS-NNN-NNN-S1-S-NN-FW belongs to the CDB Control Units series produced by Bosch Rexroth Indramat. This control card forms the central logic layer in a dual-axis drive package, managing motion commands, encoder feedback, and fieldbus traffic inside automated machinery. By translating higher-level instructions into synchronized drive signals, it helps coordinate position, speed, and torque loops for servo inverters that power industrial actuators.

Internally, the board supports 2 independent drive axes, each processed through high-impedance analog reference channels rated at 160 kΩ. This resistance keeps the command source from being loaded and preserves signal fidelity. Outgoing velocity or torque commands are created by a digital-to-analog stage with a granularity of 19.5 mV/inc, permitting fine scaling when interfacing with external regulators. All logic circuitry is powered from a DC 24 V supply that can withstand an inrush of 6 A, so upstream power modules must be sized to cope with the short charging surge. A fixed 60 ms pulse width drives the on-board watchdog relay, which can switch 30 V DC up to 1 A for status signaling.

During normal operation the unit draws only 9 W, minimizing cabinet heat. Drive controllers gain fieldbus access through the MultiEthernet master port, which supports multiple Ethernet-based protocols without extra hardware. Two identical feedback inputs accept IndraDyn/Hiperface/1 Vpp/TTL formats, allowing mixed encoder types on the same card. Functional safety is handled by the integrated Safety Technology I/O channel, eliminating the need for external safety relays. A standard front-mounted control panel enables local parameter entry, and an 8-pin Mini-DIN serial connector remains available for service tools. Because option slots 3 and 4 are not equipped, airflow inside the drive stack stays unobstructed and spare card allocation is simplified.
