Product Description:

The CSH01.1C-SE-ENS-EN1-MD1-NN-S-NN-FW is a control section assembled by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for mounting on IndraDrive power sections, this module acts as the primary processor that links motion axes, field devices, and higher-level PLCs inside automated production lines. By hosting real-time bus communication and local signal conditioning, the unit supplies deterministic command execution required for packaging, assembly, and material-handling equipment within compact control cabinets. It integrates with the drive backplane, sharing power and diagnostics channels so that wiring remains minimal in multiaxis installations.

During power-up, the controller draws a peak inrush of 4 A for up to 100 ms, after which its steady demand settles at 7.5 W. Motion and drive data are exchanged through SERCOS II, and telegram intervals can be reduced to 1000 µs when precise torque or position loops are required. Two integrated analog outputs provide direct setpoints to external devices. The first feedback port supports standard encoder evaluation, while the second accepts resolver and high-speed HSF signals, allowing mixed feedback topologies within a single axis group.

System setup is handled through the engineering port, which uses a RJ-45, 8-Pin connector linked to Ethernet 100Base-TX for setup and diagnostics. At machine level, the MD1 board supplies 12 x 24 V digital inputs for sensor states and 8 x 24 V digital outputs for actuator commands; additional channels can be added later with the digital I/O extension option. Sercos telegrams are transmitted over a fiber-optic ring to minimize electromagnetic interference, while a fallback RS232 serial link supports basic diagnostics when the bus is offline. The unit includes no integrated safety technology, so external safety relays must be used where required.
