Product Description:

The CSH01.1C-NN-ENS-MEM-MD1-NN-S-NN-FW is a single-axis control section from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Intended for installation inside IndraDrive modular inverters, the unit generates command and feedback signals that coordinate servo drives, positioning tables, and other motion elements in automated production lines. Because it does not include built-in safety circuitry, it focuses on high-speed general motion tasks rather than certified safety stop functions. It is intended for applications where motion control is handled in the drive while safety functions are managed elsewhere in the system.

During operation, the controller draws a control supply of 24 V DC, and its internal electronics consume only 7.5 W, allowing low-heat panel layouts. A brief switch-on surge of 4 A must be considered when sizing auxiliary supplies, because this inrush current affects fuse and cable selection. Communication with external PLCs is handled through an integrated RS232 serial port that supports transfer speeds up to 115 kBaud, enabling data transfer and diagnostics without a fieldbus option. This connection supports local access when no dedicated network interface is installed. The unit therefore relies on the host inverter for network connectivity, and the control communication header on this version is absent.

For encoder simulation, the board can drive incremental or SSI receivers over an emulation cable up to 40 m long, delivering square-wave pulses at rates as high as 1 MHz while sourcing 20 mA per channel. The encoder supply of 11.6 V powers external interpolation hardware, and pulse width settings can be adjusted to 100 ms when required by slower counters. Local machine I/O is provided through the MD1 extension, which offers 12 digital inputs and eight digital outputs for limit switches, home sensors, or valve actuation. The available I/O allows direct connection to common machine signals without an additional remote module. A 15 m limit on serial cable length helps maintain signal integrity, and any category-rated stop or guard logic must be handled by the upstream control system.
