Product Description:

The CSH01.1C-SE-EN1-EN2-MD2-S1-S-NN-FW is a plug-in controller card from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Installed inside Rexroth drive stations, the card commands one servo axis, reads position feedback, and exchanges motion data with a plant-level PLC. By converting high-level position targets into velocity and torque references, it supports precise, deterministic motion sequences in assembly, packaging, and machining equipment.

Electrical overhead is low because the board draws only 7.5 W, which helps minimize cabinet heat. Network traffic uses SERCOS, so the drive, controller, and I/O remain time-aligned on the same optical ring. With its single-axis rating, all processing resources are concentrated on one motion channel, which simplifies setup and preserves full loop bandwidth. The first encoder interface supplies 8 V to a resolver or HSF transducer for stable signal operation. At startup, the power rail may see 4 A of inrush, so circuit protection must tolerate this brief surge. Its MD2 slot supports digital I/O expansion and an internal SSI encoder gate, allowing high-resolution linear scales to be read without using network bandwidth. The safety input is monitored at 24 V and 3 mA, allowing direct connection of light curtains or interlock switches.

An MD2 plug-in provides 16 digital inputs, matching transistor outputs, and an SSI port so sensors and actuators can connect directly to the controller. The second feedback channel accepts a 1 Vpp sine-cosine signal and offers a regulated 5 V supply for EnDat 2.1 encoders. For emergency-stop chains, a dedicated high-side driver is rated at 24 V / 0.5 A to switch external contactors. That driver is limited to a pulse not exceeding 100 ms, which reduces the energy delivered during diagnostic tests.
