Product Description:

The CSH01.1C-PB-EN2-EN2-MEM-S2-S-NN-FW is a motion logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is intended to coordinate servo drives and related devices on a manufacturing cell, generating axis commands, evaluating feedback, and exchanging status data with a higher-level PLC or HMI. This arrangement allows the controller to serve as the link between machine-level control and the connected axis hardware during automated operation. Its control role suits machines that need local motion processing without separating feedback handling from command generation.

This unit manages one mechanical axis, so it is classified as a single-axis controller. Fieldbus communication is handled through PROFIBUS, allowing deterministic control messaging between the drive family and supervisory equipment. Command and monitoring values can also be exchanged through the integrated RS232 port for local service access. Feedback from the connected motor is accepted on two identical encoder channels, and both channels support EnDat 2.1 protocols with differential 1 Vpp and 5 V TTL signals for sine-cosine or incremental feedback. Application data and parameters are stored on a removable MultiMediaCard, so settings can be retained without manual re-entry. To accommodate local sensors and actuators, the device supplies integrated analog I/O along with separate digital inputs and outputs.

Functional safety is available under the designation Safe Motion; this feature lets the axis perform monitored stop and speed functions without an external safety relay. When drive-based position signals must be forwarded to third-party controls, the Option 3 slot provides Encoder Emulation that reproduces incremental pulses. An integrated relay output supplies a dry contact for hardware-level ready or fault indication, while the standard operator panel offers basic parameter access through front-mounted keys and LEDs. The controller’s second encoder port mirrors the first electrically, allowing redundant feedback or a second measurement transducer without extra hardware.
