Product Description:

The CSH01.1C-SE-EN2-NNN-MA1-NN-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is installed in IndraDrive drive stacks to manage a single mechanical axis. It translates higher-level commands into precise current loops, position loops, and fieldbus communication for industrial automation tasks such as packaging, handling, and machining.

Its analog front end presents an input resistance of 160 kOhm, so process sensors can be connected without noticeable loading. The built-in ±10 V channel accepts signals over a range of ±10 V, making the card suitable for both velocity and torque references. Binary actuators are driven through a digital output block rated at 24 V, 0.5 A, which is enough to energize contactors or indicator lamps directly. Feedback data are digitized with a resolution of 12-bit, and the same resolution is used for internal arithmetic to preserve measurement fidelity. Rotary or linear encoders connect through a versatile interface that supports EnDat 2.1 / 1 Vpp / TTL, allowing the controller to accommodate absolute, incremental, and analog sinusoidal feedback devices.

An isolated supply rail of 5 VDC delivers up to 350 mA to power the attached encoder without an external converter. The optional MA1 channel complements this by offering two differential inputs and two ±10 V analog outputs that use the same resolution, enabling onboard velocity feedforward or process value forwarding. Real-time motion commands reach the section via Sercos. Its optical layer uses fiber-optic transmission, and the twin ports X20 (transmit) and X21 (receive) support ring or line topologies with automatic delay compensation. This arrangement allows the module to coordinate a standalone axis with deterministic timing while maintaining electrical isolation from noisy plant environments.
