Product Description:

The CSH01.3C-PL-EN2-EN2-CCD-S2-S-NN-FW is a motion-control module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Within multi-axis drive systems, this controller manages feedback, safety, and network tasks so connected drives respond accurately to setpoint commands and changing machine conditions. It serves as the local control layer between higher-level PLCs and power inverters, coordinating position loops and supervising Safe Motion functions in automated equipment that requires reliable axis monitoring.

The unit provides 1 analog input for accepting process variables such as a torque command or external reference signal. It also has 2 analog outputs that can source 1 mA at 5 V across a 5 kΩ load, allowing reference values to be passed to compatible external devices. For discrete signal handling, the controller includes 11 digital inputs for fast status monitoring and 4 digital outputs, each rated for 500 mA, for driving contactors or indicator lamps. All logic ports share a common supply, and the total load must remain within 1.1 A digital I/O current so the internal electronics stay within their operating limits.

Field connectivity is handled through CCD cross communication, allowing direct data exchange between drives in coordinated applications. The feedback interface accepts EnDat 2.1 / 1Vpp / TTL encoder signals, supporting precise position evaluation for closed-loop motion control. An Ethernet-based engineering port provides access for setup and diagnostics, while a parallel master interface transfers setpoint data with low latency from the central controller. Motion safety is managed by integrated Safe Motion (SIL2 / Cat. 3 PL d) logic, which can actuate a hardware relay rated at 24 VDC, 1 A to interrupt power during a safety event. An RS232 serial interface is also available for service diagnostics when network access is not used.
