Product Description:

The CSH01.1C-S3-ENS-EN2-MD1-NN-S-NN-FW is a control section module manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. The unit plugs into an IndraDrive power section to provide axis control, parameter storage, and fieldbus connectivity. By generating setpoint data and processing feedback signals, it coordinates servo motors and actuators in packaging machines, printing lines, and material-handling cells.

Its architecture supports a single-axis configuration, meaning one drive channel is processed on the board. Command traffic is exchanged over SERCOS III, so deterministic cyclic data can reach the drive with very low latency. The MD1 extension furnishes 12 digital inputs for limit switches or sensors and 8 digital outputs for contactors or pilot valves, with logic-level isolation on each channel. Two encoder supplies are present: channel 1 delivers 12 V for IndraDyn or HIPERFACE devices, while channel 2 provides 5 V for EnDat or TTL encoders. These interfaces allow simultaneous evaluation of absolute and incremental feedback without additional converter modules. The optional digital I/O extension occupies the third slot when installed.

Logic and sensor circuits draw up to 1.1 A from the internal 24 V bus, helping maintain stable switching of field signals without external relays. Both the input and output stages operate at 24 V, so wiring can follow standard machine-control pinouts. A maintenance port using RS-232 enables parameter backup and service access with a laptop in non-real-time mode. The single-line panel display presents status codes during startup, and the standard front panel houses membrane keys for local resets. The module has no integrated safety technology, so safe torque off must be implemented with external hardware when required.
