Product Description:

The CSH01.1C-S3-ENS-EN2-NNN-S2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power units, it acts as the command processor that links the drive with a master control system, executing real-time motion algorithms for positioning, speed regulation, and torque limitation in automated assembly lines, packaging machines, and material-handling workcells. This arrangement lets the control section handle motion processing while remaining integrated within the overall drive platform.

Its analog I/O stage delivers a maximum output current of 1 mA and can drive monitoring equipment with load impedances down to 5 kΩ. Each step of the converter changes the voltage by 19.5 mV per increment, a resolution that comes from an internal 8-bit digital-to-analog converter. Two encoder channels are available: channel 1 has 120 ohms of input resistance, can source 500 mA, and supplies 11.6 V to sine-cosine or TTL sensors, while channel 2 is rated for 35-ohm loads, provides 350 mA, and outputs 5.0 V for low-power feedback devices. Parameterization and service access are possible through an asynchronous serial link that reaches 115 kBaud on the RS-232 maintenance port.

The control core exchanges cyclic setpoints with the plant network over SERCOS III through an integrated electrical gateway that terminates on an 8-pin RJ-45 connector, keeping wiring consistent with standard Ethernet patch leads. For functional safety, the board implements the Safe Motion package and drives field actuators through a pair of galvanically isolated outputs rated at 24 V / 0.5 A. When higher current is required for external relays, an auxiliary contact rated for 24 V / 1 A is provided. These dedicated safety channels work alongside the analog stages and encoder supplies, allowing the controller to command, monitor, and reliably disable motion within one compact slot.
