Product Description:

The CSH01.2C-PB-ENS-EN2-CCD-S1-S-NN-FW motion control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed in a multi-axis drive rack, this module executes real-time axis control, processes encoder feedback, and exchanges fieldbus data so that servo inverters follow commanded positions and speeds. Its role is to bridge PLC instructions to the power electronics and motor sensors, forming the logic core of an IndraDrive automation cell.

At the signal level, the controller provides 2 analog outputs with a resolution of 19.5 mV/inc, allowing fine-grained command of external actuators. Its base power draw is 8.5 W, so the unit imposes a modest load on the control cabinet supply. Four discrete terminals are configured as 4 combined digital I/Os, selectable as inputs or outputs by parameter. Bus communication with the higher-level PLC is carried over PROFIBUS-DP, while peer data exchange between Rexroth drives runs on IEEE 802.3 Ethernet; this separation keeps motion data independent of plant traffic. RS-232 diagnostics are available up to 115 kBaud. One normally open relay contact offers galvanically isolated signaling to auxiliary circuits, and the integrated Safety Technology I/O block supports safe stop and emergency interlock functions.

Output drivers can source 500 mA of digital output current for solenoid or lamp loads, while the dedicated EN2 rail supplies 350 mA at 5 V to power incremental encoders. A separate ENS circuit offers 12 V at 500 mA for absolute encoder transducers. The card routes cross-drive messaging through its onboard Ethernet interface. Encoder Interface 1 accepts IndraDyn, HIPERFACE, and 1 Vpp signals, and Encoder Interface 2 operates with EnDat 2.1, 1 Vpp, or 5 V TTL formats.
