Product Description:
The CSH01.1C-PL-ENS-EN2-MEM-NN-S-NN-FW is part of the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. This plug-in control card is intended for IndraDrive systems, where it closes real-time position, speed, and current loops for servo axes. By combining encoder channels, discrete I/O, and a front-mounted single-line display, the card passes machine states to the power section and forwards drive feedback to a supervisory PLC for coordinated motion. Its role is to process motion data quickly enough that the connected drive can respond to changing command and load conditions without losing control stability.
The card exchanges command data through a Parallel Interface that terminates on a backplane D-Sub 37 connector, and this mapping supports time-critical handshake signals between the drive and a machine-level sequencer. Sixteen discrete inputs and sixteen outputs are onboard, providing 16 parallel inputs for limit switches and 16 parallel outputs for contactors or lamps. The auxiliary function of Encoder Emulation replicates incremental signals so external counters can track position without an additional sensor. A single-line control panel display shows parameter numbers and error codes, and local status remains visible even when no external HMI is connected. For high-resolution feedback, the primary encoder socket accepts IndraDyn, Hiperface, or 1 Vpp sine-cosine transmitters, allowing precise interpolation inside the drive.
Secondary feedback is handled by the EN2 channel, which uses a D-Sub 15 connector. That port supplies reference power at 5 V, sources up to 350 mA, and expects the encoder to present about 35 ohms of termination resistance. These electrical limits help maintain signal quality over longer cables and reduce reflections at the input. Supported formats include EnDat 2.1, 1 Vpp, and 5 V TTL, giving flexibility for absolute or incremental devices. The ENS rail provides an additional 12 V supply for external sensors, and the single-line display confirms voltage presence during startup. This allows the control card to work with several common feedback types without an external converter.
