Product Description:
The CDB01.1C-SE-EN1-EN1-NNN-MEM-NN-S-NN-FW is a compact control unit from the CDB Control Units series manufactured by Bosch Rexroth Indramat. It is intended to coordinate multiple drive modules inside an automation cell, supplying timing, feedback processing, and fieldbus exchange required for precise motion tasks. By integrating power-stage commands, feedback conversion, and network communication in one assembly, the device simplifies cabinet layout while maintaining deterministic response for servo positioning and speed regulation.
This model manages up to 2 configured axes and links to the higher-level PLC through SERCOS II, allowing real-time transfer of setpoints and status data. Inside the motion loop the current controller runs every 125 µs, so torque corrections can be issued before mechanical lag becomes significant. Each digital output can source up to 500 mA, letting it drive relays or optocouplers directly. Position feedback may be duplicated on the optional encoder emulation port as SSI Absolute, which simplifies downstream registration tasks. Two resolver/HSF interfaces accept primary feedback. The resolver windings are energized with a 4 kHz carrier, and the resulting 18.2 Vpp signal is conditioned internally. The HSF channel provides an 8 V DC supply for high-speed feedback heads. One normally open relay contact is available for ready or fault signaling.
The controller includes 2 analog outputs for variable-speed references or instrumentation. High-speed machine synchronization is aided by the MEM output stream, which can toggle at up to 1 MHz. Cycle time on the SERCOS ring can be reduced to 1000 µs when application bandwidth demands it, and an auxiliary RS-232 maintenance port communicates at 115 kBaud for parameter loading or service diagnostics. These interfaces support coordinated motion on machinery that requires tight current, speed, and position control across multiple axes.
