Product Description:

The Bosch Rexroth Indramat CSH01.1C-S3-EN1-EN2-NNN-L2-S-NN-FW is a control section from the CSH Advanced Controllers series. Mounted inside an IndraDrive modular drive stack, it manages motion axes and field devices through integrated I/O and network interfaces. The unit functions as the central processor that links servo inverters to higher-level PLCs in industrial automation, handling setpoint generation, feedback evaluation, and safety interlocking for coordinated multi-axis movement. This arrangement lets one module coordinate drive commands and local device signals within the same control stack. Its extension slot allows compatible updates without exchanging the control section, which helps extend service life.

The control board provides one differential analog input that accepts signals up to ±10 V; this range allows direct connection of standard feedback sensors without additional scaling circuitry. Input impedance is specified at 160 kΩ, so source devices experience only a minimal load. A single analog output delivers 5 V / 1 mA, enabling the board to forward calculated setpoints to external monitors. Digital acquisition is handled by eight channels rated at 24 V / 3 mA, while eight sourcing outputs can switch actuators at 24 V / 0.5 A. These electrical ratings support direct wiring to compatible sensors and actuators.

For network control, the module employs the SERCOS III real-time Ethernet bus through dual RJ45 connectors, which supports deterministic cycle times across multiple drives. The encoder supply on the En1 port can source up to 250 mA at 8 V for legacy MHD or MKD feedback devices, while the En2 port supports EnDat 2.1 and TTL formats with a higher drive capability of 350 mA. When certified shutdown behavior is required, the integrated safety circuit provides Safe Torque Off. This function removes drive energy without interrupting fieldbus communication, so the controller can remain connected during a safety stop.
