Product Description:
The CDB01.1C-SE-EN2-EN2-MEM-MA1-NN-S-NN-FW is a plug-in control section from the CDB Control Units series manufactured by Bosch Rexroth Indramat. Designed for installation inside IndraDrive modular inverters, this board coordinates drive functions, fieldbus communication, and local analog or encoder feedback in multi-axis automation. By translating high-level motion commands into precisely timed drive signals, it serves as the intermediate controller that links programmable logic controllers to servo or spindle amplifiers used on packaging, printing, and material-handling equipment. Its layout supports coordinated motion tasks in which command timing, feedback processing, and network communication must remain aligned across several axes.
The analog interface accepts input swings up to ±10 V, allowing direct connection to standard process transducers or velocity setpoints. Signals are digitized with 12-bit resolution so the control electronics can resolve small command changes with stable response. Two analog input lines are provided as 2 differential pairs, and the board also generates two voltage outputs for reference feedback to external equipment. Motion commands and status data travel over the real-time fiber-optic network SERCOS II, giving deterministic cycle times in synchronized axis groups. For encoder supplies, an onboard regulator delivers 5.0 V to EnDat 2.1, 1 Vpp, or 5 V TTL feedback devices, eliminating the need for external power rails.
The encoder ports can source up to 350 mA, enough for dual high-resolution sensors while maintaining galvanic separation between internal and external grounds. Sense-guided feedback lines may be extended to a maximum of 75 m without degrading position accuracy when the correct cable is used. Auxiliary electronics on the card draw from the I/O bus, which must supply no more than 1.1 A at 19 to 30 V DC to maintain thermal limits. Current-generated analog outputs can drive loads down to 35 ohms, permitting direct actuation of proportional valves and similar devices. This arrangement lets the control section support both feedback handling and external signal interfacing from the same plug-in module.
