Product Description:
The CSH01.1C-ET-EN2-NNN-NNN-S1-S-NN-FW is a drive controller hardware module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It mounts inside IndraDrive power sections to execute motion commands, manage fieldbus communications, and supervise safety I/O in industrial automation cells. By processing encoder signals and network traffic in real time, the unit coordinates servo axes so conveyor lines, packaging stations, or pick-and-place robots reach commanded positions with deterministic timing.
For host connectivity, the module uses a Multi-Ethernet interface that can switch between several real-time protocols without additional hardware. Two front-panel ports marked 2 x RJ45 (8-pin) are wired to the copper physical layer and conform to the 100Base-TX standard, allowing twisted-pair cabling up to 75 m. Legacy devices may be linked through an RS-232 port that reaches a maximum data rate of 115 kBaud. Closed-loop positioning accuracy is supported by a sine analog-to-digital converter with a resolution of 12 bit, and the converter maintains linearity up to the 500 kHz cutoff frequency. The single-line control panel lets users read status or step through parameter numbers without external software. The encoder connector is a D-Sub 15-pin plug that accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals, and the sense leads can be routed up to the full 75 m length.
The encoder supply rail delivers 5.0 V at up to 350 mA, enough for high-resolution optical or magnetic feedback transducers. Functional safety is implemented locally, and a 9-pin female D-Sub provides channelized inputs and outputs for the controller’s Safety Technology I/O circuitry. A dry contact rated at 24 V DC / 1 A enables direct interlock of external contactors. The safety electronics draw their logic power from a dedicated 24 V DC feed, so motion tasks remain isolated from emergency-stop wiring. This arrangement keeps the safety circuit separate from the motion-control functions during normal operation and stop requests.
