Product Description:
The CSH01.1C-NN-ENS-EN1-MEM-L2-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive servo inverters, the module executes motion sequences, supervises feedback channels, and distributes fieldbus data so that drives can coordinate axes in industrial automation cells. It interfaces directly with embedded sensor nodes and higher-level PLCs, providing the computation and signal conditioning layer between machine control logic and power electronics. Because the control section is separate from the inverter power stage, it focuses on command processing, feedback evaluation, and network exchange within the drive.
The controller offers one differential analog input that accepts a full-scale range of ±10 V and is buffered by a 160 kΩ input resistance to protect upstream sensors. Its single analog output delivers up to 5 V with a step size of 19.5 mV/inc, allowing fine reference generation for external amplifiers. Internal logic and communication draw only 7.5 W, an important consideration when sizing cabinet power supplies. Control data reach the module through Multi-Ethernet, while an auxiliary RS-232 maintenance port supports serial transfers for setup and diagnostics. The safety layer is implemented through a Safe Torque Off channel that can remove drive power without cycling the control CPU.
Position feedback from EnDat encoders is energized by a carrier of 4 kHz at 18.2 Vpp, and the ENS interface supplies 11.6 VDC with 500 mA available for external sensors. Digital outputs can source 500 mA per channel, and the MEM high-speed measurement bus propagates edge-aligned pulses at 1 MHz with a logic high of 5 V; cabling on this link can extend up to 40 m without repeaters. For legacy equipment, an asynchronous link operates at 115 kBaud. This mix of interfaces lets the section support fast motion signals, sensor supply functions, and communication with older serial equipment in the same system.
