Product Description:

The CSH01.1C-C0-ENS-NNN-NNN-NN-S-NN-FW control module is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This card mounts beside IndraDrive power sections and executes position, velocity, and torque loops for electric axes. It converts fieldbus commands into synchronized motion signals and manages local digital and analog I/O. This layout lets one module coordinate command processing, feedback handling, and local signal exchange inside the drive system.

The analog output channel has a resolution of 19.5 mV/inc, allowing fine voltage trimming when the drive responds to external feedback. The ENS encoder interface digitizes incremental tracks with a 12-bit width and uses an input resistance of 120 ohms to support stable signal acquisition. A selectable low-pass characteristic limits spectrum content above 500 kHz, and the dedicated encoder supply provides 11.6 V so compatible SinCos or TTL devices can be powered directly from the module. Discrete machine signals pass through relay contacts rated at 1 A, and the bus line is terminated on the board with 124 ohms to reduce signal reflections on the connection.

This controller supervises 1 mechanical axis, so applications with additional axes require more control channels on the same drive platform. Network communication is handled through the integrated CAN interface, which supports CANopen and DeviceNet and can address as many as 127 subordinate devices on one segment before expansion hardware is needed. The same connector block carries five poles, and its clamping screws must remain within the stated tightening limit to protect the threads and maintain a secure electrical connection. For service access, the RS-232 diagnostic port supports line speeds up to 115 kBaud, allowing parameter transfer and trace capture without using the fieldbus.
