Product Description:

The CSH01.1C-SE-ENS-NNN-MD2-L2-S-XP-FW is a motion and I/O controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It serves as the central command card in modular drive stacks, coordinating multiple axes while exchanging high-speed data with servo inverters. By combining logic processing with field-level connectivity, the unit handles positioning, speed control, and safety-related signal exchange in automated machinery and material-handling lines. This arrangement allows several machine functions to be managed from one control platform instead of being distributed across separate modules.

This controller integrates digital I/O and an SSI encoder channel, allowing discrete sensors and absolute position feedback to share one board. The auxiliary interface provides 16 individually configurable input points and an equal number of output points, with each channel delivering up to 0.5 A. Base power consumption is 7.5 W, which helps limit added cabinet heat in compact installations. Motion commands and diagnostic telegrams are exchanged over SERCOS II, and the card’s TTL capture can process edge transitions up to 400 kHz for pulse-train functions such as electronic gearing. Typical inrush current is 4 A, and discrete events can be stretched to a maximum pulse width of 100 ms when longer acknowledgment times are required.

The encoder interface uses a 15-pin female D-Sub connector and standard encoder evaluation, supplying the sensing head with up to 500 mA at a regulated 11.6 V. Synchronous communication to other Rexroth masters reaches a bus rate of 16 MBaud, supporting fast data exchange in coordinated systems. Relay outputs can switch external interlocks or contactors rated at 24 V DC, 1 A, which is useful when the control section must command peripheral devices directly. Safe Torque Off is implemented as the primary safety layer, removing drive energy without additional wiring and helping the controller fit into compact multi-axis assemblies.
