Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PB-EN2-EN2-MEM-L2-S-NN-FW control section within the CSH Advanced Controllers series. The unit is mounted on IndraDrive power stages and serves as the motion and communication core for multi-axis machinery. It interprets encoder data, exchanges commands with higher-level PLCs, and generates gate signals that keep servomotors synchronized during coordinated positioning, printing, or material-handling tasks. By combining safety circuitry with fieldbus and feedback interfaces, the board allows automated equipment to maintain deterministic speed, torque, and position profiles under varying load conditions.

Its electrical overhead is limited to 7.5 W of base consumption, simplifying cabinet thermal design. Fieldbus traffic arrives through the PROFIBUS channel, and a D-Sub 9 female connector carries the differential RS485 signals so the controller can join existing line-topology segments. During power-up, the card can draw a 4 A inrush, an allowance to consider when sizing supply breakers. The secondary encoder port provides a regulated 5.0 V source on a D-Sub 15 female plug, and its line termination of 35 ohms matches shielded feedback cables to minimize reflections. It also accepts incremental or EnDat feedback while forwarding replicated pulses whose width can reach 100 ms.

An SSI channel supplies absolute position emulation, and the board can switch between absolute and incremental modes to match system requirements. The primary and secondary feedback inputs support EnDat 2.1, 1 Vpp sin-cos, and 5 V TTL signals, allowing a wide range of linear or rotary encoders. Up to 350 mA is available on the encoder supply for external sensors. Drive-level safety is implemented through the Safe Torque Off function on a dedicated D-Sub 9 female STO connector, which removes gate commands when the circuit is de-energized. Diagnostics and setup are handled via the onboard RS232 serial port.
