Product Description:

The CSH01.3C-PB-EN1-NNN-CCD-L2-S-NN-FW belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. As a modular control section for IndraDrive units, it supervises axis tasks, processes feedback, and links the drive to higher-level automation systems. Its role in industrial automation is to coordinate motion sequences, monitor safety states, and translate fieldbus commands into real-time drive signals.

The controller accepts differential process signals within a ±10 V analog input window, and a high input impedance of 160 kΩ minimizes sensor loading. It can source a 5 V / 1 mA analog output for reference generation to external modules. Base power demand is limited to 8.5 W, yet the unit draws a momentary 4 A inrush at startup, so supply breakers must tolerate that surge. The main supply is DC 24 V, which also feeds a digital output channel rated at 24 V / 0.5 A for actuator switching. A maximum pulse width of 100 ms applies to probe latches, and time-critical capture is supported by 1 µs probe accuracy. Resolver and HSF encoder evaluation lets the drive close position loops without external cards.

Field communication uses PROFIBUS-DP for plant-wide control while drive-to-drive coordination is handled by a SERCOS III Master interface. Parameter access over the serial service port is provided through RS232. Integrated safety complies with the Safe Torque Off function; the corresponding STO input expects 24 V at 3 mA to enable power. Auxiliary relays can switch DC 24 V loads up to 1 A, allowing direct alarm lamp or contactor control. A relay-free path is available through the 24 V / 0.5 A digital output for faster response. Together these interfaces, timing features, and safety circuits let the control section fit into mixed-protocol machines while maintaining deterministic motion and certified shutdown behavior.
