Product Description:

The CSH01.3C-CO-ENS-ENS-CCD-S2-S-NN-FW is a single-axis control section from Bosch Rexroth Indramat in the CSH Advanced Controllers series. The module is intended to mount on Indramat drive racks and coordinate servo motion, fieldbus communication, and safety functions in automated machinery. By combining high-speed encoder evaluation, multiple network interfaces, and integrated logic, the unit acts as the command layer between PLCs and power stages and supports deterministic position control with safe torque-off routines.

Each ±10 V analog output has a resolution of 19.5 mV/inc, so motion commands can be adjusted in fine 512-step increments across the full span. While operating, the section draws a base load of 8.5 W, which is useful for cabinet thermal planning. A 124 ohm CANopen terminator is factory installed to maintain signal integrity on the network, which can support up to 127 nodes before repeaters are needed. Position feedback is filtered at 500 kHz to match high-resolution encoders. The sensor supply provides 11.6 V to transducers, and supplementary data lines follow the IEEE 802.3 cross-communication standard. TTL command inputs accept edges up to 400 kHz, and digital outputs can source 500 mA for pilot relays or optical isolators.

A separate DeviceNet channel supports 64 nodes for legacy plant segments. During cold start, the logic capacitance can draw 4 A of inrush current, so upstream protection must account for the temporary surge. Once energized, the onboard relay contacts can switch up to 1 A DC for functions such as motor brake control. Encoder inputs use 120 ohm termination and can supply 500 mA, while the TTL monitor accepts edges down to 15 ns. A dedicated D-Sub 9-pin Safe Motion connector carries STO and SLS signals, and the RS-232 service port remains reliable with cable lengths up to 15 m for offline diagnostics.
