Product Description:

The CSH01.2C-NN-EN2-MEM-CCD-NN-S-NN-FW is a single-axis controller module manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive power section, the card executes position, velocity, and logic commands that coordinate connected servo drives, sensors, and field I/O. By combining internal processing with dedicated encoder and network interfaces, it provides deterministic motion control for packaging lines, material-handling stations, and general factory automation cells. Its role is to handle axis regulation and local control tasks inside the drive platform rather than rely on a separate standalone motion controller for every function.

The module operates from a control supply of 24 VDC and draws a base load of 8.5 W, which helps keep control-power demand modest within the cabinet. Each analog input presents 160 kΩ of resistance, reducing source loading, while the analog output stage supplies up to 1 mA with a resolution of 19.5 mV/inc for reference generation. Digital inputs accept 24 VDC signals at 3 mA, and the transistor outputs switch 24 VDC loads at 0.5 A, allowing direct connection of sensors, interlocks, and command signals. At power-up, the unit absorbs a 4 A inrush for 100 ms, so the upstream supply must tolerate that short transient. Relay contacts are rated for 24 VDC at 1 A, allowing galvanically isolated fault signaling to external circuits.

For feedback, the En2 interface sources 5.0 VDC and can deliver 350 mA to high-resolution encoders, while the channel input impedance of 120 Ω helps maintain signal quality on longer cable runs. A memory expansion slot supports a maximum data clock of 1 MHz for fast parameter backup and data handling. The engineering port follows the 100Base-TX Ethernet standard, giving real-time access to drive parameters without using fieldbus bandwidth. This arrangement keeps encoder support, memory functions, and service communication on the controller module in a single pluggable assembly.
