Product Description:

The CSH01.1C-PB-EN2-NNN-MD1-S2-S-NN-FW is a motion-control processor card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power section, the board provides the real-time computing core that closes position, velocity, and torque loops for connected servo axes. It receives encoder feedback, exchanges fieldbus data, and executes integrated safety routines so mechanical movements stay synchronized with higher-level PLC commands. By assigning these tasks to a dedicated slot module, the drive cabinet gains deterministic axis coordination without relying on an external motion CPU.

Field communication is handled through PROFIBUS, enabling cyclical data exchange with the plant controller at standard 12 Mbaud rates. Each analog channel accepts a differential span of ±10 VDC and is buffered by an input impedance of 160 kΩ to prevent loading of remote sensors. Two single-ended outputs are present; each can source 5 VDC / 1 mA, and the base analog output count is 2, which is useful for external setpoint generation. Position feedback arrives on terminal X4, which supports the mixed-signal interface EnDat 2.1 / 1 Vpp / TTL, allowing absolute or incremental encoders to be selected without hardware changes.

The controller’s MD1 terminal provides 12 digital inputs and 8 transistor outputs, while heavier loads can be switched by an isolated relay contact rated at 24 VDC / 1 A. Motion supervision is implemented through the Safe Motion package, and the integrity of these circuits is certified to SIL2 / Cat. 3 PL d, permitting their use on axes that require controlled stops or limited-speed monitoring. Despite the I/O density, the board occupies only 49.5 mm of cabinet width, with a depth of 103 mm and a height of 241 mm, supporting compact multi-axis drive stacks without sacrificing signal capacity.
