Product Description:

The CSH01.1C-CO-ENS-NNN-NNN-L2-S-NN-FW is a drive controller section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It mounts beside an IndraDrive power module and provides the closed-loop control needed for servo torque, velocity, and position in automated machinery. Through its integrated fieldbus, encoder, and I/O resources, the unit coordinates real-time motion sequences used in packaging lines, pick-and-place robots, and light machining cells.

The controller has two differential analog input channels with a high input impedance of 160 kOhm, which helps minimize loading on external transducers. These channels accept signals within a ±10 V range for standard process feedback. All discrete I/O rails are powered from a dedicated 24 V DC source, and the sink-type digital outputs can supply 0.5 A per point. Motion feedback is handled through a primary encoder interface rated for IndraDyn / Hiperface / 1 Vpp / TTL, allowing compatibility with several common sensor types. A standard control panel on the front supports parameter entry, and an RS232 service port remains available for diagnostics. Since module slots X8 and X10 are not equipped, the unit keeps a simpler base configuration and leaves expansion functions to the adjacent drive section.

The controller supports functional safety through Safe Torque Off (SIL3 / cat. 3 PL e), which allows the axis to meet demanding risk-reduction requirements without external relays. The housing is 241 mm high, 103 mm wide, and 49.5 mm deep, so it fits within a single drive bay while leaving space for airflow. Field communication with the supervisory PLC is handled through CANopen / DeviceNet, which helps reduce wiring when several drives share a common bus. Relay signaling is provided by a 1 A contact for interlock chains, and the digital outputs use the same control voltage as the rest of the I/O system.
