Product Description:

The CSH01.1C-ET-ENS-EN1-MEM-NN-S-NN-FW is a drive controller option card produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive power section, this card provides central motion logic and fieldbus routing for automated machinery. It accepts encoder feedback, distributes sensor power, and exposes Ethernet ports so that axis drives and higher-level PLCs can exchange real-time data. In an industrial automation line, the unit coordinates velocity, position, and diagnostic information across multiple servo axes. This lets the controller card manage communications and feedback tasks without requiring a separate external control module.

Normal operation is sustained through a control supply of 24 VDC; this low-voltage rail feeds the internal logic that draws only 7.5 W, which helps limit panel heat. Networking is handled by a Multi-Ethernet interface, so protocols such as EtherNet/IP or PROFINET can share the same port. Shared network access can simplify integration when supervisory control and drive traffic use the same physical interface. The optional EN1 encoder channel is excited by 18.2 Vpp and is sampled at 4 kHz, allowing sinusoidal encoders to report fine interpolation values during rapid axis movements. During start-up, inrush current is capped at 4 A, and the card rejects input pulses wider than 100 ms to improve immunity to wiring faults.

The secondary EN1 logic rail delivers 8 VDC to power incremental sensors, while the ENS output furnishes 12 VDC with a maximum sourcing capacity of 500 mA for external limit switches or reference encoders. These low-voltage outputs let connected feedback devices operate directly from the controller card. Memory-based position tracking uses an SSI absolute format that can clock data at up to 1 MHz, and the Ethernet connection is carried on an RJ-45 8-pin connector for 100Base-TX communication. The maximum cable length for the SSI channel is 40 m to preserve signal quality. Because the card includes no integrated safety technology, safe-torque-off and emergency-stop functions must be handled through separate safety hardware.
