Product Description:
Bosch Rexroth Indramat supplies the CDB01.1C-SE-EN2-EN2-EN2-EN2-L1-S-NN-FW, a plug-in control section within the CDB Control Units series. Fitted to a compatible power module, it orchestrates drive regulation for machines that demand precise positioning, coordinated speed loops, and deterministic data exchange. The card integrates axis logic, encoder processing, fieldbus management, and diagnostic resources, making it a compact control core for packaging lines, material-handling gantries, assembly stations, and similar automated equipment. By centralizing these tasks, the unit reduces overall panel complexity and keeps key control functions in one section.
The card regulates 2 servo axes and exchanges cyclic command data over the SERCOS II fiber-optic interface. Each axis accepts fast reference events through digital inputs rated at 24 V / 3 mA, while process feedback can be routed to analog monitors that provide 5 V / 1 mA sourcing capability. Motion telegrams can be refreshed every 1000 µs, giving the drive an update rate suited to path interpolation. The board also supports high-resolution EnDat 2.1, 1 Vpp, and 5 V TTL encoder channels for precise feedback processing. A separate RS-232 port can stream service data at 115 kBaud, and the probe latch input records position events with 1 µs accuracy for camming or print-registration duties.
During operation, the controller draws a base load of 9 W, so thermal rise inside the drive rack remains low even when the typical inrush current reaches 6 A for a 60 ms pulse at power-up. The board provides 4 feedback sockets for the supported encoder formats, enabling dual-loop setups without external splitters. Command relays can switch 24 VDC at 1 A, a shielded service port maintains configuration links, and PWM cycles never exceed 8 kHz to limit motor heating. A built-in safety layer enforces a Starting Lockout, letting machine builders satisfy Category 0 stop rules.
