Product Description:

The CSH01.1C-ET-EN2-NNN-MEM-L2-S-NN-FW is a control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. When plugged into an IndraDrive power module, it supplies motion logic, fieldbus links, and encoder processing so that multi-axis machines can position, regulate speed, and limit torque under one coordinated program in automated packaging, handling, or machining equipment. The controller’s galvanic isolation limits ground loops, and its combined signaling capabilities reduce external wiring.

Each of the card’s two analog voltage outputs completes a conversion cycle in 10 µs, enabling fine interpolation of velocity or torque setpoints. The step height of 19.5 mV/inc is the minimum command granularity delivered to the drive. Four digital outputs are rated for up to 24 V / 0.5 A, making them suitable for contactor actuation or status signaling. For simulated encoder feedback, the emulation channel is galvanically isolated and can drive 20 mA differential signals over motor cables. It supports frequencies up to 1 MHz, allowing high-speed incremental or absolute feedback reproduction. A maximum emulation line length of 40 m maintains signal integrity across large machines, and the channel can replicate both absolute and incremental formats without external converters.

The second feedback socket, labeled EN2, accepts EnDat 2.1, 1 Vpp, or 5 V TTL encoders, and its sense lines may be routed as far as 75 m with the prescribed shielded cable. The interface tolerates 35 ohms of load resistance and sources 350 mA to power reading heads. Network connectivity for higher-level controllers is provided through 100Base-TX Ethernet, while diagnostics can still be performed through an RS-232 port that reaches 115 kBaud. A relay output rated at DC 24 V / 1 A is available for ready or fault indication. Machine safety is integrated through the certified Safe Torque Off function, which removes drive energy without altering parameterization.
