Product Description:

The CSH01.3C-PL-ENN-CCD-NN-S-NN-FW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. This module is a drive controller option card that integrates motion control, analog I/O processing, and network handling inside IndraDrive power sections. Within an automation cell, it conditions field-level signals, executes current and velocity loops, and exchanges status data with higher-level PLCs. This arrangement allows the drive to coordinate axis behavior and local machine signals without requiring a separate interface card for each control task.

The analog input stage offers a common-mode rejection of 48 dB, allowing differential measurements to ignore most external noise. Each input is digitized through a 12 bit converter and is terminated by a 160 kΩ impedance, which helps minimize sensor loading at the input channel. The effective step size on these inputs is 1.23 mV/inc, so small voltage variations can be captured without external amplification. On the output side, setpoint voltages are produced through an 8 bit DAC, and the signals can drive instrumentation or inverter reference inputs when the load remains at or above 5 kΩ. Parallel interfacing is handled with 16 discrete inputs and 16 discrete outputs, enabling direct start-stop, limit, or interlock wiring without extra remote I/O hardware. This mix of analog and digital channels supports feedback devices, reference signals, and simple machine interlocks through the same control platform.

Back-plane and peer-to-peer traffic rely on the Ethernet-based standard IEEE 802.3, giving the card access to high-speed messaging when paired with compatible motion networks. Torque commands are refreshed every 62.5 µs, which helps the controller respond quickly to changing load conditions during synchronized motion. During power-up, the inrush profile is limited to 4 A for 100 ms, protecting cabinet circuit breakers, while each digital output can source up to 500 mA for solenoid or relay loads. Total board demand is only 8.5 W, so added heat inside the drive remains low even when the analog and parallel channels are active. The low board demand also helps compact multi-axis assemblies manage internal temperature without adding separate cooling hardware for the option card.
