Product Description:

The CSH01.1C-PB-EN2-NNN-MEM-L2-S-NN-FW controller module is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit serves as the central processing section inside drive assemblies, where it executes axis commands, monitors feedback data, and exchanges field-level messages with higher automation layers. Designed for industrial motion systems, the board coordinates power-stage behavior so motors start, stop, and position accurately under PLC supervision. Its compact format lets it mount directly on a drive stack, which helps reduce internal cabinet wiring and keeps the control layout compact. This arrangement lets one module manage command handling and feedback evaluation in the same location, which supports consistent response during speed and position control.

Powered from a control bus of 24 V DC, the module draws only 7.5 W during steady-state operation, which helps limit heat dissipation inside the drive. A brief inrush of 4 A appears when the supply is first applied. The integrated PROFIBUS-DP port links the unit to PLC networks, and the auxiliary RS232 port supports local setup and diagnostic access. Event inputs accept trigger windows of up to 100 ms, and a standard front control panel provides local parameter access, while data can be loaded through the memory card slot if removable storage is used. Because the front panel is built in, routine status review and parameter entry can be done at the drive without relying on network access.

The encoder interface accepts EnDat 2.1 / 1 Vpp / 5 V TTL feedback and supplies 5 V ±5% to the sensor line. With encoder emulation included, the controller can forward simulated incremental pulses to devices that do not process serial feedback directly. That combination supports use with feedback devices that provide serial data as well as applications that still need incremental-style signals for related equipment. The safety channel implements Safe Torque Off, allowing rapid energy removal from connected amplifiers without external relays. Nonvolatile storage for motion data and log files resides on a MultiMediaCard, which keeps operating data available after power is removed.
