Product Description:

The CSH01.1C-CO-ENS-NNN-MEM-S2-S-NN-FW is a controller module produced by Bosch Rexroth Indramat for integration into the CSH Advanced Controllers series. When mounted in a Rexroth drive assembly, this module handles local motion logic, routes fieldbus traffic, and generates encoder-compatible feedback so multiple axes can run in tight electronic gearing. Its role in industrial automation is to coordinate servo drives, translate network commands into deterministic motor actions, and supervise the safety layer used on modern production lines. This arrangement lets the control section manage motion sequences and feedback translation inside the drive assembly instead of relying on a separate external controller for every function.

The control electronics are powered from a logic rail of DC 24 V, and under steady operation the module draws only 7.5 W, which helps limit cabinet heat load. Fieldbus connectivity is provided through a protocol stack that supports CANopen / DeviceNet, allowing the controller to exchange cyclic process data with PLCs over the 5-pin spring-terminal CO port. At startup, a charging circuit limits energy flow, yet an initial surge of 4 A for 100 ms must be considered when sizing the supply. The ENS encoder supply delivers 11.6 V at 500 mA for external sensors, and the RS232 service port handles diagnostic communication through a separate cable. A single-line display on the front panel reports status codes without requiring a separate HMI, which allows basic status checks directly at the module.

High-speed feedback is carried over the MEM interface, which produces position pulses at 1 MHz and supports remote encoder heads up to 40 m away. The same electronics also provide an asynchronous link for parameter tuning and service communication, so setup and diagnostics can be handled without additional interface hardware. The motion platform incorporates Safe Motion technology so axes can decelerate or hold when safety inputs change, and this layer operates independently of the main CPU. Additional features include SSI format emulation, a 9-pin female D-Sub on the S2 connector, and 24 V / 3 mA digital inputs for hardwired triggers. These inputs can be used for external events such as reference marks or simple machine interlocks.
