Product Description:
The Bosch Rexroth Indramat CDB01.1C-PB-ENS-ENS-EN2-NNN-NN-S-NN-FW is a modular control section installed on IndraDrive power stages within the CDB Control Units series. Acting as the command and communication core, this plug-in module processes setpoints, monitors feedback, and exchanges data with higher-level PLCs to coordinate motion axes in automated assembly lines, packaging equipment, and material-handling stations. By combining fieldbus connectivity with onboard encoder evaluation, it streamlines axis control tasks and allows each drive to be matched to the sensor and network requirements of the installation. Because the control section mounts directly on the drive power stage, signal handling and motion coordination stay closely integrated within the axis hardware.
The module draws a base load of 9 W from the DC bus, and it can tolerate a momentary 6 A inrush when the drive rack is energized. Communication with central controllers uses a PROFIBUS-DP channel that operates at up to 12 MBaud, which helps reduce telegram latency when multiple axes share the segment. Command recognition on the fast digital channels begins at a logic high threshold of 15 V. Discrete actuator chains can be driven directly through an integrated relay rated for 24 VDC, 1 A, which allows simple switching of external status or control circuits.
The CDB01.1C variant also supports sourcing outputs up to 500 mA, enabling it to switch external status lamps or contactors. In the encoder section, the ENS channel filters signals to 500 kHz and accepts TTL edges up to 400 kHz, while its receiver has 120 Ω input resistance and a regulated supply for encoder electronics. The EN2 channel supplies 350 mA at 5.0 V and is intended for transducers that meet the 35 Ω load requirement. For service access, the front-panel 9-pin connector provides an RS-232 port that reaches 115 kBaud, and cable runs can extend to 15 m without signal conditioners. This layout supports local parameter access and diagnostic communication through a standard serial connection.
