Product Description:
The CDB01.1C-SE-ENS-ENS-EN2-MEM-NN-S-NN-FW is a drive control section developed by Bosch Rexroth Indramat for the CDB Control Units series. Installed in modular inverters, the unit processes signals between motion controllers and power stages in industrial automation cells. It coordinates encoder data, fieldbus communication, and local I/O so servo axes receive timely torque and velocity commands. By housing both primary and auxiliary sensor interfaces on one board, the control section simplifies cabinet wiring and setup.
At the analog level, the board sources an output current of 1 mA or an output voltage of 5 V for test or trim points that need a low-power reference. Communication with the drive system uses SERCOS II, allowing cycle-synchronous data exchange with deterministic latency. The unit includes 7 digital inputs for opto-isolated discrete commands. Machine status can be propagated externally through 4 digital outputs. For edge-triggered measurements, the card offers 2 fast probe inputs; these channels are synchronized with the motion bus and support a memory-based capture stream that reaches 1 MHz. These real-time resources permit speed and position verification without external oscilloscopes.
Primary feedback ports accept dual IndraDyn, Hiperface, or 1 Vpp sin-cos encoders, while auxiliary feedback can read EnDat 2.1, TTL, or additional 1 Vpp devices, enabling mixed-sensor topologies within the same axis group. The unit provides no integrated safety functions. The internal encoder emulation outputs both absolute and incremental formats so legacy controllers remain supported. During oscilloscope mode, the probe circuit guarantees a minimum pulse width of 4 µs, and the onboard relay can switch control voltages up to 24 VDC / 1 A to actuate interlocks, brake releases, or status lamps.
