Product Description:

The CSH01.1C-NN-EN2-NNN-MEM-NN-S-XP-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Designed as the command layer for IndraDrive power units, it processes motion profiles, manages local I/O, and provides the timing backbone for multi-axis machinery in assembly lines, packaging cells, and material-handling stations. It works with the drive software to execute interpolation tasks and sequence logic that would otherwise require an external PLC, reducing cabinet complexity while maintaining deterministic performance across synchronized axes.

It offers two differential analog input channels that accept a maximum signal range of ±10 V, and a built-in resistance of 160 kΩ helps prevent loading of the upstream transducer. The unit also includes one analog output that supplies up to 5 V / 1 mA for reference or test signals. Twenty-four digital input terminals are intended for industrial sensors and consume only 24 V / 3 mA per point, while eight transistor outputs switch field devices at 24 V / 0.5 A. These channels let the controller accept velocity commands, monitor limit switches, and energize contactors without additional interface cards, while the relay contact block supports DC 24 V at 1 A for auxiliary alarms and the internal memory module stores parameter sets without a separate external supply.

The En2 option board dissipates only 6 W, so cabinet ventilation demands remain low even when the unit starts with an inrush of 4 A. Motion feedback arrives through a multiprotocol encoder port that accepts EnDat 2.1 signaling, delivers a regulated 5 V supply to the sensor, and can emulate incremental outputs through a dedicated encoder-emulation circuit. The logic domain is powered by a busbar supply of DC 19 to 30 V, so no separate memory rail is needed. For low-noise position loops, feedback cables may extend to 75 m when sense lines are used or 50 m without them, and the unequipped control-communication slot allows higher-level networking to be added through separate SERCOS or EtherCAT modules when required.
