Product Description:

The CDB01.1C-SE-EN1-EN1-MEM-MA1-NN-S-NN-FW is a compact control section produced by Bosch Rexroth Indramat for the CDB Control Units series. Installed on compatible drive controllers, it supervises axis functions, manages fieldbus traffic, and provides local I/O so that servo amplifiers can be coordinated within an automation cell. By concentrating communication, signal conditioning, and motion-related timing on a single plug-in card, it simplifies cabinet wiring and shortens controller response paths in multi-axis machine tools, printing systems, and material-handling stations.

This module draws only 9 W of base power, which helps limit heat buildup inside densely packed enclosures. Command exchange with higher-level PLCs runs through the SERCOS II interface, providing deterministic cycle times and standardized telegram structures. Each digital output can source up to 500 mA, allowing it to switch relays or optocouplers directly without external boosters. The EN1 encoder connector delivers a stabilized reference of 8 V for feedback devices, helping maintain signal integrity over typical cable runs. For time-critical positioning, the probe input accepts capture pulses as short as 60 ms. The unit also includes two MA1 analog inputs, two analog outputs, a relay path rated at 24 V DC / 1 A, and resolver excitation of 18.2 Vpp.

High-speed data latching is supported by a MEM output that toggles at up to 1 MHz, which is useful for drive-synchronized strobe signals. Position capture accuracy is held within 1 µs, so encoder events remain closely aligned with the servo cycle. Diagnostic access over the RS-232 port reaches 115 kBaud and supports cable lengths up to 15 m for local setup and diagnostics. During power-up, a typical inrush current of 6 A should be considered when selecting circuit protection. The card also includes a 10 kΩ HSF input for high-speed signal handling.
