Product Description:

The CSH01.1C-SE-EN2-ENS-MD1-S1-S-NN-FW is a controller plug-in module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in a Rexroth drive rack, it manages axis control, fieldbus communication, and safety supervision within automated production equipment. By integrating motion algorithms and interface circuitry on a single board, the unit synchronizes servo motors, encoder feedback, and external sensors so that assembly, packaging, and printing stations maintain precise speed and position profiles. This arrangement keeps control functions close to the drive system and reduces the need for separate interface hardware.

The module links to the drive master through a fiber-optic ring that carries the SERCOS II protocol, giving deterministic cycle times and immunity to electrical noise. One analog channel supplies a reference of 5 V / 1 mA for proportional actuators or diagnostics. Encoder channel 1 provides 11.6 V to IndraDyn S, HIPERFACE, or EnDat 2.1 transducers, while channel 2 outputs 5.0 V with a maximum draw of 350 mA for EnDat 2.1, 1 Vpp, or 5 V TTL devices. Separate encoder supply levels allow the module to support different feedback technologies without external signal converters. A standard control panel can be docked to the front for local parameter access, and a ready relay rated 24 V / 1 A signals operational state to other controllers.

The MD1 expansion furnishes 12 x 24 V digital inputs for limit switches and 8 x 24 V digital outputs for contactors or stack lights. Functional safety lines are integrated, and the power stage for safe output is limited to 24 V / 0.5 A, while associated 24 V / 3 mA inputs and 24 V / 1 A relay contacts support emergency stop chains. A built-in RS232 port offers point-to-point serial access for diagnostics and service tasks while the optical ring remains active. The digital, analog, and safety connections support drive-ready signals, status reporting, and orderly shutdown commands when required.
