Product Description:

The Bosch Rexroth Indramat CSH01.1C-PB-NNN-NNN-MD2-L1-S-NN-FW is a single-axis control section in the CSH Advanced Controllers series. It fits into Rexroth drive racks where it supervises servo amplifiers, gathers field data, and issues motion commands to higher-level PLCs, giving automated cells coordinated axis control. Its hardware platform combines dedicated signal processing and bus interfaces so cycle times stay predictable even when multiple axes and sensors operate at the same time, which removes the need for a separate PC-based controller.

At the I/O level, the MD2 expansion supplies 16 digital inputs and an equal number of digital outputs, each routed through a D-Sub HD 44-pin connector for panel wiring. 2 analog channels are available; they deliver 5 V and sink or source up to 1 mA, making them suitable for setpoint signaling to external drives or transducers. The module can energize devices that draw 0.5 A per point and count pulses from high-speed sensors without extra conditioning. For fieldbus traffic, the control section relies on PROFIBUS, linking the axis drives with plant PLCs. These resources let the board execute position, velocity, and torque commands while supporting auxiliary machine functions.

Service and encoder interfaces are separated on the unit for straightforward machine integration. Fieldbus wiring exits through the D-Sub, 9-pin female connector, while a Mini-DIN 8-pin RS232 port supports setup and diagnostics. Incremental or absolute encoders that use synchronous serial interface are accepted through the RJ12, 6-pin socket. Emergency conditions are handled electrically; a Category 0 stop removes power to all outputs, and the integrated Starting Lockout prevents uncontrolled restart after a fault reset. The enclosure measures 241 mm in height, 49.5 mm in width, and 103 mm in depth, allowing side-by-side mounting in 300 mm control cabinets without violating airflow clearances.
