Product Description:

The CSH01.2C-PL-ENS-MA1-CCD-L1-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. As a motion and I/O expansion controller, it coordinates drive tasks and peripheral signaling inside modular automation cells. Its role is to link drive amplifiers, feedback devices, and field-level sensors so that position, velocity, and process variables are controlled in real time under a centralized command structure. In distributed machine layouts, it serves as the control point that connects axis commands with external signals and feedback activity.

This unit draws a base power of 8.5 W, a modest demand that simplifies cabinet thermal calculations. Command data reach the controller over a Parallel Interface, while deterministic peer exchange between multiple master devices is handled through IEEE 802.3 Master cross-communication. Rotor position feedback is accepted through a multifunction encoder port that supports IndraDyn, HIPERFACE, 1 Vpp formats; the port supplies up to 500 mA at an encoder voltage of 11.6 V. The base unit includes one analog input and two analog outputs for voltage or current references. An extension board adds two differential analog inputs and two additional analog outputs, and a single normally open relay contact can switch auxiliary circuits. This arrangement allows the controller to handle both drive feedback and process-side analog signaling within the same platform.

The digital header offering 16 Inputs / 16 Outputs is used for fast machine status collection such as guard switches, product sensors, and interlock signals. During startup, the device limits line stress with an inrush current ceiling of 4 A. Functional safety is addressed by the built-in Starting Lockout, which inhibits drive enable lines after a fault or emergency stop until a reset sequence is completed. That behavior helps prevent unintended motion when the machine is restarted after an interruption.
