Product Description:

The CSH01.1C-S3-EN1-EN1-NNN-L2-S-NN-FW motion logic controller is built by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It mounts alongside IndraDrive power units and issues position, velocity, and torque commands so multi-axis machinery can follow programmed profiles with millisecond accuracy. By combining Ethernet-based motion bus interfaces, safety circuitry, and encoder processing on one compact card, the module acts as the coordination layer between a central PLC and individual servo axes in industrial packaging, printing, and material-handling lines.

This controller provides an analog output step of 19.5 mV/inc for fine voltage reference generation to external actuators. Its primary Ethernet port is an RJ-45, 8-pin jack that communicates in compliance with IEEE 802.3, allowing real-time exchange over the SERCOS III motion network. Four high-side switches carry loads up to 24 V, 0.5 A for valve or relay control. The EN1 I/O extension dissipates only 6 W, while the separate S3 module requires 1 W, helping keep cabinet temperatures low. Two Resolver/HSF encoder ports capture rotor position, and a 4 kHz excitation signal is generated internally so the feedback remains synchronized with the drive algorithms.

Encoder electronics supply the transducers with 8 V and drive the resolver carrier at 18.2 Vpp, supporting accurate sine-cosine pickup. When serial diagnostics are required, the integrated RS-232 interface supports data rates up to 115 kBaud. Functional safety is delivered through the hardware-based Safe Torque Off channel, which is wired on a D-Sub 9-pin female connector. Its input monitors a 24 V, 3 mA signal, and the acknowledge path can sink 24 V at 1 A. These parameters allow the controller to remove drive power rapidly without disrupting the fieldbus or encoder supply on packaging, gantry, and conveyor axes.
