Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-NN-EN2-NNN-MEM-L2-S-NN-FW control section, a module in the CSH Advanced Controllers series. This device acts as the command element for synchronous and asynchronous drive packages, translating motion program data into real-time axis signals for industrial automation cells, packaging lines, and material-handling stations. Its primary role is to coordinate torque, speed, and position loops while interfacing with PLC networks through dedicated encoder and safety channels.

During power-up the controller draws a base inrush of 4 A, limited to a maximum pulse width of 100 ms to avoid tripping supply fuses. Once energized it maintains only 7.5 W of continuous consumption, allowing dense cabinet layouts with minimal heat dissipation. Field wiring can use the integrated digital outputs that deliver up to 500 mA per channel for contactors or signal lamps. The communication option bay is not equipped, so axis data are forwarded through the encoder and emulation ports. For legacy drives, the module provides an emulation channel that supports cable runs up to 40 m, sources 2 W internally, and reproduces reference marks at 1 MHz. STO control inputs accept 24 V logic at 3 mA and isolate functional safety from general I/O.

Position feedback handling is based on absolute and incremental encoder emulation, and the dedicated interface supports EnDat 2.1 / 1 Vpp / 5 V TTL formats. The encoder supply rail delivers 5 V while allocating 6 W for optional sensor power, enabling mixed feedback topologies over distances to 75 m when sense lines are used. The integrated safety layer activates Safe Torque Off once a fault is confirmed. The acknowledge path releases a 24 V, 1 A signal to upstream control after the drive reaches torque-free status, ensuring deterministic restart sequencing without duplicating interlocks.
