Product Description:

The CSH01.1C-PB-ENS-MEM-MD2-L2-S-NN-FW is an axis controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in IndraDrive inverter stacks, it executes position loops and evaluates encoder data. It forwards setpoints to power modules, linking individual servo axes to supervisory PLCs in automated assembly, packaging, or material-handling equipment. This layout keeps axis control functions in the controller while the power section handles motor current.

The controller connects to higher-level control systems through PROFIBUS, providing deterministic cyclic exchange of motion parameters and status bits. An analog process channel presents an input resistance of 160 kΩ, so external sensors are not heavily loaded by the interface. Sixteen MD2 digital inputs accept 24 V logic, while the module can source up to 16 digital outputs at 0.5 A each for actuating contactors or pneumatic valves. Feedback connectors accommodate IndraDyn and Hiperface encoders; a regulated 12 V supply energizes the transducers, and the controller can emulate both absolute and incremental signals for auxiliary devices. These emulation channels are galvanically isolated, which helps separate feedback circuits from connected equipment. The integrated evaluator processes position words internally and passes them to the motion kernel without external converters, which streamlines cabinet wiring.

An RS-232 port supports service access and transmits parameter sets at up to 115 kBaud. For functional safety, the unit implements Safe Torque Off, and its safety input draws only 3 mA during operation. The acknowledgment path is rated at 24 VDC / 1 A, allowing direct connection to standard safety relays. Absolute position handling is standardized on the SSI format, complementing the integrated evaluator and supporting high-resolution multi-turn encoders.
