Product Description:

The CSH01.2C-NN-ENS-NNN-CCD-S1-S-NN-FW is a control section assembled by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive stacks, the unit coordinates motion and safety channels for servo axes, translating field feedback into deterministic command words. It receives encoder signals, manages network traffic, and issues real-time setpoints to power inverters so that positioning, velocity, and safe-stop functions remain synchronized with the machine cycle. This control role lets one section supervise both axis response and communication timing inside the drive system.

Internal dissipation is limited to 8.5 W, so only convective airflow is required. At power-up, an input surge of 4 A can occur for up to 100 ms, and line protection must absorb that pulse. The digital supply rail available for onboard I/O carries 1000 mA, while the interface accepts differential 5 V TTL position pulses at rates up to 400 kHz. Position resolution uses a feedback converter width of 12 bits. For programming and diagnostics, the board provides an IEEE 802.3-compliant Ethernet port that supports the 100Base-TX engineering link and eliminates the need for custom cables. A single analog monitor channel delivers 5 V at 1 mA for scope probing of internal variables during setup and troubleshooting.

The encoder subsystem is powered by 11.6 V at up to 500 mA, and its 120 ohm input resistance terminates transmission lines to reduce reflections. Signal bandwidth extends to 500 kHz, supporting high-speed sine-cosine transducers. Setup laptops can be located up to 100 m away because the engineering cable length is specified at that distance. For integrated safety, the controller provides a relay contact rated at 24 V / 1 A and a separate solid-state output rated at 24 V / 0.5 A for logic-level interlocks. The relay path can be used for switching safety circuits, while the solid-state path suits signal-level shutdown chains.
