Product Description:

The CSH01.1C-SE-EN2-NNN-MD1-NN-S-NN-FW is a single-axis motion and logic module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in modular drive platforms, it coordinates position, speed, and diagnostic data between drives and higher-level PLCs. The card provides the computation and fieldbus interfaces needed to sequence servo axes, handle local I/O events, and support deterministic communication in automated assembly cells and material-handling stations.

Its logic core is powered from a control circuit of 24 V DC, while cyclic setpoints and status words are exchanged over the SERCOS II fiber-optic ring to maintain sub-millisecond synchronization with compatible inverters. The analog process channel has an input resistance of 160 kΩ, which minimizes loading on external signal conditioners. Internal electronics draw only 7.5 W at base load, reducing panel thermal rise. For direct machine feedback, the MD1 extension offers 12 digital inputs that can latch edge-triggered events for rapid response tasks such as registration mark capture or over-travel interlocks.

In the output domain, the card can source up to 500 mA per channel, allowing it to actuate contactors or light curtains without external relays. Analog transmission to downstream regulators is available as a 5 V analog output with 1 mA drive capability for transducers that expect voltage references. Parameterization and service access are available through the RS-232 port operating at 115 kBaud, a rate that is fast enough for parameter transfer while remaining tolerant of long cables inside cabinets. Power-up surge is constrained to a 100 ms inrush window and a typical 4 A peak, helping designers size supply breakers and limit electromagnetic interference. Additional encoder provisions include EnDat 2.1, 1 Vpp, and 5 V TTL formats with 35 Ω load and 350 mA supply support, enabling direct wiring of high-resolution feedback devices without separate adapters.
