Product Description:

The CSH01.1C-S3-EN1-NNN-NNN-S2-S-NN-FW advanced controller is part of the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. This compact control section mounts inside IndraDrive stacks and governs servo axes in assembly lines, packaging machines, and general motion platforms. By combining axis logic, fieldbus communication, and safety monitoring in a single slot, the unit coordinates real-time motor commands and feedback within an industrial automation cell.

Its base electronics draw only 7.5 W, limiting heat generation inside the cabinet. The analog input channels present 160 kOhm of resistance, so connected sensors experience minimal loading, while each analog output can source up to 1 mA for loop-powered devices. On the discrete side, the module supplies 500 mA per digital output, enough to drive contactors or optocouplers directly. A power-up surge of 4 A is tolerated by the internal capacitors before the bus voltage stabilizes. Motion and parameter data are exchanged over the deterministic SERCOS III network, giving cycle times compatible with multi-axis interpolation. These values describe the controller's electrical loading, signal capability, and network operation.

The feedback interface accepts resolver signals driven at 4 kHz and referenced to 18.2 Vpp; these enter a dual-purpose Resolver/HSF evaluator that also powers high-speed feedback devices with 8 VDC at 250 mA. Parameterized pulse outputs may be stretched to 100 ms, supporting diagnostics that require longer strobe widths. The controller's S3 port is an RJ-45, 8-pin connector wired for 100Base-TX, enabling direct copper cabling to switches or drive peers. The RS-232 link can extend 15 m for local setup and diagnostic access. Safe Motion technology supervises velocity, position, and standstill functions without interrupting the main bus.
