Product Description:

Bosch Rexroth Indramat manufactures the CSH01.3C-PB-EN2-EN2-CCD-L2-S-NN-FW, a plug-in motion and logic module in the CSH Advanced Controllers series for IndraDrive platforms. The module acts as the central processor for one or two drive axes, interpreting encoder signals, exchanging commands with higher-level PLCs, and issuing torque or velocity setpoints to the power stages. Its role in industrial automation is to synchronize motor movement, monitor safety channels, and coordinate network traffic so that packaging lines, gantries, and handling robots maintain precise trajectories. It also supports coordinated machine behavior by linking feedback processing with real-time control tasks inside the drive system.

Field device traffic is carried over PROFIBUS-DP, and the module sustains a cyclic bus rate of 12 MBaud, which helps reduce telegram latency during time-critical motion tasks. Two Ethernet connectors with a 2 × RJ-45 layout form the cross-communication interface; this interface operates at 100Base-TX under the IEEE 802.3 standard and lets multiple drives share position data without an external switch. Dual encoder slots accept feedback in the EnDat 2.1 / 1 Vpp / 5 V TTL format, allowing mixed use of absolute optical encoders and incremental sine-cosine transducers on separate axes. The built-in safety channel supports Safe Torque Off, which removes gate signals to the power stage when an emergency condition is detected and allows operation to resume after the fault is cleared.

The encoder supply delivers 5.0 V at up to 350 mA, removing the need for an external sensor power rail in many installations. Controller electronics draw a base power of 8.5 W, so cabinet thermal load remains low during standby, yet the inrush current peaks at 4 A, which requires properly rated line filters and fuses. The module also supports cross-bus master operation and RS-232 diagnostics at 115 kBaud, giving the drive system a compact supervisory layer for motion feedback, safety monitoring, and deterministic command handling. This arrangement helps keep control functions centralized without adding separate interface hardware.
