Product Description:

The CSH01.3C-CO-ENS-NNN-CCD-S2-S-NN-FW is a compact motion and communication controller manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in drive cabinets, it generates setpoint signals, gathers feedback, and mediates network traffic so that servo drives and peripheral I/O stay synchronized with the higher-level PLC. Its role is to coordinate axis movement and auxiliary devices in production machinery where deterministic timing is mandatory.

The controller has 2 analog voltage channels that provide motion references. With a resolution of 19.5 mV/inc, each command signal can be trimmed precisely within the ±10 V span. The converter that produces those signals operates with an 8-bit width, giving 256 discrete steps for each waveform update. On the network side, the control bus can be wired as CANopen or DeviceNet, and the module accepts up to 127 CANopen nodes and 64 DeviceNet nodes. A 124 Ω, 1% bus terminator rated at 200 mW is integrated so the trunk line can be ended locally when the controller is installed at the last position. Ethernet cross communication follows the IEEE 802.3 standard, providing a familiar physical layer for diagnostics and data exchange.

High-resolution feedback processing is handled through a D-Sub 15 female connector. The differential lines present a 120 Ω input, and incoming pulses are filtered at a ceiling of 500 kHz so incremental encoders do not alias at maximum machine speed. The controller supplies up to 500 mA to power external encoders, and its internal output stages can switch at 16 kHz, a frequency that helps keep current ripple low in modern permanent-magnet motors. A dedicated RS-232 serial interface is provided for setup and service. It supports cable runs up to 15 m and communicates at 115 kBaud, providing a reliable fallback link when fieldbuses are unavailable.
