Product Description:

Bosch Rexroth Indramat builds the CSH01.1C-PL-ENS-EN1-EN2-L1-S-NN-FW control section as part of the CSH Advanced Controllers series. The unit slots into an IndraDrive power stage and executes axis commands, feedback evaluation, and safety responses required for multi-axis automation cells. By combining analog, digital, and encoder interfaces on a single board, it coordinates drive current loops, synchronizes motion sequences, and supervises emergency stop behavior in production machinery.

Analog acquisition is protected by an input resistance of 160 kOhm, minimizing load on upstream sensors and maintaining signal fidelity. The controller can retransmit reference levels through an analog output that sources a maximum of 1 mA, which is adequate for standard drive regulators. Command data reaches the board through a Parallel Interface, and sixteen digital inputs are complemented by sixteen transistor outputs that can each deliver 500 mA to actuators such as contactors or indicator lamps. Resolver feedback on channel EN1 is energized with 18.2 Vpp, while auxiliary Hall sensor power is available at 8.0 VDC. The module’s digital I/O scheme follows Stop Category 0 so that energy is removed without controlled deceleration once a stop request is detected.

Encoder channel EN2 furnishes quadrature devices with 5.0 VDC, and its signal receiver tolerates up to 350 mA of load, allowing long cable runs in harsh environments. For high-speed incremental encoders on the ENS connector, TTL edges are accepted up to 400 kHz, and the associated supply rail of 11.6 VDC supports sensors drawing as much as 500 mA. Safety acknowledgment logic is powered from 24 VDC / 1 A, while user signals observe a 24 V level at 3 mA to reduce wiring stress. Field cabling terminates on a 37-pin D-Sub header that matches standard ribbon assemblies and preserves compact installation inside the control cabinet.
