Product Description:

The CSH01.1C-SE-ENS-NNN-NNN-S2-S-XP-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. As a control section, it forms the interface between higher-level automation systems and the power electronics of an IndraDrive unit. It provides the signal processing and fieldbus communication needed for coordinated motion sequences in industrial machinery.

This section receives analog feedback through inputs that present an impedance of 160 kΩ, and the high resistance helps prevent loading of sensor circuits. Each incremental step on that channel corresponds to 1.23 mV/inc, enabling fine-grained conversion of low-level process signals. Analog commands are returned on an output that can drive loads down to 5 kΩ, and every step on that path is quantized at 19.5 mV/inc, matching typical ±10 V command ranges. Internal electronics draw only 7.5 W of base power, leaving most cabinet capacity for actuators. For deterministic axis coordination, it exchanges real-time data over the SERCOS II optical ring. A differential input with 120 Ω termination is included for noise-immune high-speed reference pulses, while an SE expansion module is supported with a dedicated 2 W supply to power option boards without overloading the main bus.

A digital output stage can source up to 500 mA, allowing direct actuation of status lamps or small relays, and the TTL capture circuit accepts encoder marker frequencies as high as 400 kHz. The embedded encoder supply delivers 11.6 V at 500 mA through a D-Sub 15-pin female connector, providing both power and reference signals for incremental transducers. Safety-related wiring is routed to a dedicated D-Sub 9-pin female socket, and Safe Motion functions are included to support machine safety. Serial diagnostics remain accessible over RS-232 cables up to 15 m, allowing local setup without a network connection.
