Product Description:

The CSH01.2C-PB-EN2-NNN-CCD-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It functions as the central processor in an IndraDrive stack, coordinating servo and spindle axes so automated machinery tracks programmed motion profiles. By combining fieldbus handling, encoder evaluation, and local I/O on one board, the module reduces panel wiring and supports deterministic cycle execution for packaging lines, assembly stations, and material-handling cells. This arrangement keeps motion control, feedback processing, and network communication in one place, helping the drive system respond consistently during coordinated machine movement.

The controller draws 8.5 W of base power and withstands an inrush of 4 A, allowing quick energization without oversizing the supply fuse. Analog command channels present an input impedance of 160 kOhm, minimizing load on upstream sensors, while the corresponding output delivers 5 V / 1 mA with a resolution of 19.5 mV/inc for fine trim signals. Discrete states arrive on IEC 61131 Type 1 lines that expect 24 V / 3 mA. Drive parameters, diagnostics, and motion commands move over the PROFIBUS-DP interface integrated on the card. Low-side transistor outputs switch 24 V loads up to 0.5 A, and a 100 ms maximum pulse width rating applies to momentary functions such as brake release or clamp signals. The combination of analog channels, digital inputs, and bus communication allows the control section to exchange reference values, status signals, and interlocks with surrounding machine hardware.

Multi-axis synchronization is provided through the SERCOS III Master port, enabling drives to share a common real-time cycle for contouring tasks. A dedicated safety input enforces the rated Starting Lockout, blocking drive-enable signals until external guards or PLC logic confirm safe conditions. For galvanically isolated control, an onboard relay can switch DC 24 V at 1 A, and its contacts are rated for 1 × 10⁸ cycles, supporting frequent actuation over long production runs without mechanical replacement. That separation between motion synchronization and safety-related enable logic supports controlled startup behavior in multi-axis systems.
