Product Description:
The CSH01.1C-NN-EN2-MEM-MA1-L2-S-NN-FW control section is a plug-in module for Bosch Rexroth Indramat IndraDrive stacks and belongs to the CSH Advanced Controllers series. It serves as the central processing and I/O interface within an IndraDrive stack, linking feedback channels, analog references, serial links, and safety circuits to the drive firmware. It sits between the machine controller and the power section so command and feedback data can be handled in one place. Because it is a control section rather than a power stage, it focuses on signal handling, coordination, and interface management instead of motor current generation. This supports precise torque, speed, and position regulation in packaging, printing, and automated assembly stations.
Channel EN2 tolerates a load resistance of 35 ohms, draws up to 350 mA from the logic rail, and is energized at 5.0 V. The same channel accepts position data through the EnDat 2.1 / 1 Vpp / 5 V TTL interface, so the controller can read absolute or incremental feedback without external adapters. MA1 is the dedicated analog channel, and it presents a ±10 V differential input span with 12-bit resolution for accurate command capture. The channel can source 10 mA across an identical output span, and a 12-bit digital-to-analog converter helps reproduce that reference consistently during closed-loop operation.
A separate MEM transmitter produces complement-phase pulses, and it can deliver 20 mA line-driver current while switching at up to 1 MHz. The complement-phase output helps maintain signal reliability over longer cable runs and in electrically noisy drive cabinets. For diagnostics, the board offers an RS-232 port that communicates at 115 kBaud. Functional safety wiring is handled by the STO circuitry: the control input needs 24 V at 3 mA, while the acknowledge output provides 24 V DC / 1 A to signal that safe torque off has cleared.
