Product Description:

The CSH01.3C-ET-ENS-MEM-CCD-NN-S-NN-FW is an axis-control hardware module manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside an IndraDrive power section, it supervises velocity loops, position loops, and network data so servo drives follow commands from a supervisory PLC without drift. The module bridges motor feedback, local inputs, and real-time Ethernet traffic, allowing coordinated multi-axis motion in packaging, handling, and machining equipment. Because the control electronics are integrated into the drive platform, the unit supports compact machine layouts where communication and feedback processing must remain close to the power stage.

The analog interface is tuned for sensor compatibility, offering an input resistance of 160 kΩ that helps prevent signal loading, while the output side can source 5 V at 1 mA for reference generation. Digital logic accepts control bits at 24 V / 3 mA and can drive actuators at 24 V / 0.5 A, giving the controller direct contact with limit switches, relays, and similar machine signals. A current-control loop that refreshes every 62.5 µs shapes the motor phase currents, and this fast cycle works with a maximum PWM switching frequency of 16 kHz to reduce torque ripple. Multi-Ethernet connectivity carries common industrial protocols, allowing the same control section to communicate across different plant networks without changing the hardware.

For simulation duties, an emulation channel streams step signals up to 1 MHz, enabling high-resolution encoder feedback tests during setup and diagnostics. Dedicated encoder power rails supply DC 11.6 V at up to 500 mA, eliminating the need for an external supply on SSI, EnDat, or Hiperface transducers. Relay outputs are rated at DC 24 V / 1 A for contactor control, which helps the controller interact with external switching devices from the same platform. The card operates as a SERCOS III master for deterministic cross-communication, while its Multi-Ethernet slave port handles standard fieldbus traffic for upstream control integration.
