Product Description:

The CDB01.1C-SE-ENS-ENS-EN2-MA1-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat within the CDB Control Units series. Designed for mounting on an IndraDrive power module, it governs two synchronized axes, conditions encoder signals, and routes safety channels for automated machining cells and material-handling stations. This arrangement allows the drive to execute the position, velocity, and torque loops required for coordinated motion.

This unit commands 2 axes and exchanges cyclic setpoints with the PLC over the SERCOS II fiber-optic interface, so synchronized motion can be maintained between connected drives. Internal electronics draw only 9 W, so cabinet thermal load remains low during continuous operation. Each digital input is sensed at 24 V / 3 mA, matching standard sensor power rails, while every transistor output can source up to 24 V / 0.5 A for contactor coils or indicator lamps. The available I/O lets the control section exchange status and permissive signals with surrounding machine hardware during normal operation. The ENS encoder ports supply 12 V to absolute or incremental sensors, whereas the EN2 connection feeds 5 V for mixed-signal formats. Inrush limiting reduces start-up stress on the backplane, and the integrated S1 safety I/O monitors enable lines without an external relay.

During power-up the module accepts an inrush current of 6 A for a maximum of 60 ms, after which consumption returns to its steady 9 W level. Two MA1 analog channels, with two inputs and two outputs, operate with 12 bits of resolution, permitting fine speed trim or torque feed-forward, and they can handle reference and monitoring signals without a separate analog interface. A built-in relay can switch loads up to DC 24 V / 1 A, providing galvanic isolation for emergency-stop chains. Three encoder receptacles, including two ENS connections and one EN2 connection, accept EnDat 2.1, 1 Vpp, or 5 V TTL feedback and can deliver 350 mA on the 5 V rail. Safety technology identified as S1 I/O links door switches and light curtains directly to the drive.
