Product Description:

The CSH01.1C-SE-ENS-NNN-NNN-L2-S-XP-FW is a single-axis controller module produced by Bosch Rexroth Indramat and supplied within the CSH Advanced Controllers series. It serves as the motion and safety interface between a higher-level PLC and the power section of an IndraDrive system. The module coordinates position, velocity, and torque commands for industrial automation tasks such as packaging, printing, and material handling. Its role in the drive system is to manage command processing and feedback exchange so that the connected axis can respond accurately during continuous machine operation.

For networked drive topologies, the unit exchanges cyclic setpoints and feedback over the SERCOS II fiber-optic ring. An auxiliary RS-232 service port supports cable runs up to 15 m at 115 kBaud, while the analog monitor channel can source 5 V at a maximum of 1 mA with a resolution of 19.5 mV/inc for diagnostic measurements. Internal logic and interface electronics draw 7.5 W of base power, and the module can withstand an inrush current of 4 A at power-up. The encoder connector supplies 11.6 V at 500 mA to incremental or absolute sensors and accepts differential input signals, allowing the controller to work with common feedback devices used in closed-loop motion systems.

High-speed position feedback is processed with a cutoff frequency of 500 kHz, and the input impedance is 120 ohms to match standard line drivers. Encoder data is synchronized to the drive clock through the SERCOS telegram, which supports stable position handling during cyclic operation and helps maintain timing consistency between command values and returned feedback. Safety wiring terminates on a D-Sub 9-pin female connector, and the integrated Safe Torque Off function disconnects torque paths when the safety circuit is activated. This arrangement allows the controller to combine motion control, encoder handling, and a dedicated safety shutdown function within the same module.
