Product Description:

The CSH01.2C-S3-ENS-EN2-CCD-NN-S-NN-FW is a modular motion control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Integrated into a Rexroth drive stack, this unit executes axis control, field networking, and encoder evaluation for coordinated multi-axis automation. It acts as the command layer that interprets high-level machine instructions and issues synchronized setpoints to the connected power stages, thereby enabling precise position, velocity, and torque regulation in packaging lines, printing presses, and general factory cells.

The main communication backbone is SERCOS III, used both for drive control and for cross-communication when this card operates as the network master. Parameter access and service functions are handled through the 100Base-TX engineering port, letting connected PCs perform setup and diagnostics without interrupting real-time traffic. A legacy RS-232 service socket supports data rates up to 115 kBaud for simple terminal access. The built-in probe input samples position triggers with an accuracy of 1 µs, which is suitable for registration marks or press cams. For analog process coupling, the module can source a reference of 5 V that is isolated from the internal logic rails.

Current-driven interfaces are also provided. The programmable analog channel can deliver up to 1 mA, and discrete outputs switch loads up to 0.5 A to actuate contactors or indicator lamps. Two encoder supplies are available: the first delivers 11.6 V at 500 mA for IndraDyn or HIPERFACE sensors, while the second offers 5 V at 350 mA for EnDat or TTL transducers, allowing mixed feedback topologies on one controller. For interlocking with higher-level safety circuits, a form-C relay rated at 24 V / 1 A provides galvanically separated status feedback. These ratings limit the connected loads and supported sensor combinations.
