Product Description:

The CSH01.1C-ET-EN2-EN2-NNN-L2-S-NN-FW is an advanced motion controller module manufactured by Bosch Rexroth Indramat and supplied within the CSH Advanced Controllers series. The unit mounts in a drive stack to coordinate servo axes, handle local digital and analog signals, and forward process data to supervisory automation systems. By integrating high-speed Ethernet links and encoder interfaces, it serves as the computational center that synchronizes motor torque, speed, and safety functions throughout an installation.

Power consumption for the logic board is limited to 7.5 W, allowing dense cabinet layouts without excessive thermal load. Each analog output can drive loads down to 5 kΩ, ensuring precise voltage signals even when connected to common industrial transducers. The digital input block is rated for 24 V, 3 mA, while the digital output stages can source up to 24 V, 0.5 A; these values indicate the I/O capability for sensors, limit switches, and contactors. Two independent feedback channels accept 2 × EnDat 2.1 / 1 Vpp / 5 V TTL encoders, and the controller supplies them with a regulated 350 mA current. Separate supply rails maintain 5.1 V when remote sense lines are unused and 5.0 V when sense wiring is present, helping prevent signal degradation over cable length.

Fieldbus traffic is carried on a Multi-Ethernet backplane that conforms to the 100Base-TX physical layer, offering deterministic communication for synchronized drives. At power-up, the module draws an inrush of 4 A for a maximum of 100 ms, so upstream fusing and supply units must tolerate this brief surge. The onboard relay channel can switch loads up to DC 24 V, 1 A, providing an isolated path for brake release or contactor actuation. Safe Torque Off is implemented in hardware, disabling gate signals instantly, and the analog outputs remain stable across the specified 5 kΩ load to support consistent reference generation.
