Product Description:
The CSH01.1C-NN-EN2-NNN-MEM-L1-S-NN-FW is a motion-logic control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive power section, it supervises axis positioning, manages local I/O, and enforces the built-in starting-lockout safety function during machine startup. In an industrial automation line, the card serves as the command layer between higher-level PLCs and servo amplifiers, allowing deterministic signal processing without adding a separate controller enclosure. Its placement inside the drive keeps command processing close to the power electronics, which helps the axis respond quickly to changes in machine state.
The module accepts differential analog feedback signals within a span of ±10 V, buffered by an input resistance of 160 kΩ to minimize loading on external sensors. Independent DAC stages provide 2 analog outputs that source or sink control references at a calibrated level of 5 V. The 7 opto-isolated digital inputs support mode selection, limit switches, or handshaking, and the controller samples every channel at drive bus speed. Four terminals can be configured as either inputs or outputs, which allows mixed-signal wiring without extra terminal blocks. This arrangement supports compact machine wiring when a small group of peripheral signals must terminate directly at the drive. Physical depth is 103 mm, so the card fits inside standard IndraDrive shelves while maintaining clearance for airflow and neighboring assemblies.
A transistor driver supplies field devices through a digital output channel rated at 24 V / 0.5 A, and this line can energize contactors or lamps directly. Encoder feedback is accepted over the multiline interface specified as EnDat 2.1 / 1 Vpp / TTL, giving the axis controller immediate position and sine-cosine data. Overall height is 241 mm, and width is 49.5 mm, while the board connects to emergency-stop circuitry through a D-Sub 9-pin safety connector. The unit communicates with service PCs by the RS232 serial port, which provides a direct local path for parameter access and status review. It is shipped without a master communication option, so fieldbus access is handled through the host drive, and a starting-lockout relay chain is wired internally to meet machinery safety requirements.
