Product Description:

The CSH01.1C-PB-EN1-NNN-MD2-S1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Once mounted on an IndraDrive power unit, it handles axis regulation, fieldbus traffic, and local safety monitoring. This allows the drive to interact precisely with plant-wide automation sequences.

This control section has a configured power draw of 17.5 W, which is low enough to limit cabinet heat while still supporting its signal processors and I/O logic. Machine connectivity is centered on PROFIBUS-DP, and telegrams move across this bus at up to 12 MBaud for tight cycle synchronization with the supervising PLC. A resolver and HSF interface is provided for primary position feedback, and its excitation rail supplies the encoder with 8 V. Sixteen MD2 digital inputs accept 24 V control signals, while another 16 output channels can drive opto-isolated loads or pass axis status bits to peripheral terminals. Parameter files are stored on an internal MultiMediaCard for local retention.

Additional communication is available through the RS232 serial port, which is useful for service diagnostics or early-generation control links. The integrated Safety Technology I/O option routes safety-related signals on segregated tracks. Its input threshold is 24 V / 3 mA, and the fail-safe sourcing outputs can deliver up to 24 V / 0.5 A. A relay contact rated for DC 24 V at 1 A is available for hardware interlocking such as drive enable chains. When the optional Digital I/O with SSI slot is populated, the unit can process absolute position data from an SSI encoder in parallel with standard feedback, which supports applications that combine incremental spindle feedback with absolute tooling references.
