Product Description:

The CDB01.1C-SE-EN1-EN1-EN2-MEM-L1-S-NN-FW is a double-axis control card manufactured by Bosch Rexroth Indramat for the CDB Control Units series. It plugs into IndraDrive power sections and governs motion sequences for two servo axes in automated machinery. By handling closed-loop current, velocity, and position tasks, the unit forms the interface between higher-level PLCs and the drive hardware, allowing precise axis coordination inside packaging, printing, and handling equipment. Its compact card format simplifies cabinet layouts and shortens signal paths between the controller and the inverter.

Fieldbus communication is provided through SERCOS II, so parameter data and real-time setpoints are exchanged over fiber at deterministic intervals. Each of the two axes is connected via EN1 incremental encoder inputs, and supplementary EN2 / MEM slots accommodate alternative feedback or memory modules. The two differential analog channels accept command signals within a span of ±10 V, and the input circuitry presents 180 kΩ of resistance to minimize loading on upstream sources. Two analog outputs supply velocity or torque feedback to external controllers. Current regulation is refreshed every 125 µs, while digital inputs trigger at a threshold of 24 V / 3 mA, matching standard sensor wiring.

Output logic lines can switch loads up to 500 mA each, and the carrier stage supports a maximum firing rate of 8 kHz for pulse-width-modulated control of the power section. The card is powered from a control supply of DC 24 V applied at the L1 terminal, and a matching relay contact rated at DC 24 V / 1 A is available for user signals. Two probe inputs of type 2 capture edge positions for metering or registration functions, and the minimum achievable SERCOS cycle time is 1000 µs for multi-drive networks. A safety circuit that implements Starting Lockout (L1) prevents unintended energization until all interlocks are cleared.
