Product Description:

The CSH01.1C-PL-ENS-NNN-MD2-L1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The module plugs into an IndraDrive power rack and manages motion axes, field signals, and diagnostic data inside automated machinery. By integrating high-speed encoder evaluation, digital I/O processing, and a starting-lockout safety circuit, it functions as the central processor that coordinates servo drives and prevents unintended motor starts during startup or service operations.

During operation, the controller draws only 7.5 W of base power, so cabinet heat dissipation remains minimal. At start-up it can momentarily pull 4 A, and supply breakers must tolerate this surge. System commands arrive over a Parallel Interface, which provides fixed cycle times without fieldbus latency. The encoder supply bus outputs 12 V at 500 mA for IndraDyn sensors, eliminating separate power rails. For discrete feedback, the MD2 board accepts 16 channels of digital inputs that are sampled synchronously with the drive cycle. Physical dimensions of 241 mm high, 49.5 mm wide, and 103 mm deep allow two units to share a 19-inch rack line, and the integrated starting lockout blocks drive enable until safety logic is closed.

The MD2 output side delivers 16 channels that can source 24 V loads, giving the motion program direct control of actuators. Position data is accepted through the IndraDyn/HIPERFACE/1 Vpp/TTL encoder port, enabling fine interpolation and quick fault detection. When SSI feedback is preferred, the board feeds transducers with a regulated 24 VDC supply at 0.2 A through an RJ12 connector. Pulse trains with a maximum duration of 100 ms can be generated for step-direction axes before an internal watchdog resets the channel. The controller can synchronize multiple drives and I/O points in packaging, assembly, or material-handling cells.
