Product Description:

Bosch Rexroth Indramat manufactures the CSH Advanced Controllers series, which includes the CSH01.1C-PB-EN2-NNN-CCD-NN-S-NN-FW control section. The unit is installed inside an IndraDrive power module, where it executes motion commands, processes sensor feedback, and interfaces with higher-level PLCs. By coordinating velocity, torque, and positioning loops for multiple axes, it serves as a central element in automated assembly cells, packaging equipment, and material-handling stations.

The controller exchanges cyclic and acyclic data with the master through PROFIBUS-DP, allowing the drive to receive setpoints and return status within standard fieldbus timing. For analog signaling, it offers one differential output that can source up to 1 mA. This channel is quantized in steps of 19.5 mV/inc, supporting fine reference generation for external devices or test points. High-resolution position data arrive through the multi-protocol encoder port, which accepts EnDat 2.1, 1 Vpp, or 5 V TTL formats, and its square-wave track is evaluated at frequencies up to 1000 kHz. Four software-assignable terminals can operate as inputs or outputs; when configured as outputs, each line supplies up to 500 mA, enabling direct actuation of contactors, indicator lamps, or brake relays without interposing circuitry.

Internal logic and peripheral devices are powered from the drive’s 24 V auxiliary rail, and the card draws 1.1 A under maximum load conditions. The analog output remains within its operating range when the connected instrumentation presents at least 5 kΩ of impedance, which helps prevent clipping or current limiting. To protect signal integrity, the encoder feedback can be wired with sense conductors, extending the total cable length to 75 m; installations that omit the sense pair should use a shorter run. The encoder supply is regulated at 5.0 V, while a separate buffer provides the 1.0 Vpp sine amplitude needed for incremental channels, supporting clean edge detection in high-speed motion profiles.
