Product Description:

The CSH01.1C-S3-EN1-NNN-MD2-NN-S-NN-FW is an advanced motion and logic controller board produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is installed in IndraDrive modular inverters to coordinate axis control, feedback processing, and field communication. By linking servo drives, encoders, and plant-level networks, the module handles synchronized motion sequences required in automated assembly, packaging, and material-handling cells.

The board exchanges real-time commands over SERCOS III; an RJ-45 link on the S3 channel carries this deterministic Ethernet protocol while drawing 1 W of S3 power. The EN1 encoder port supplies 8 V and dissipates 6 W, allowing resolver or Hiperface sensors attached through the combined resolver and HSF interface to receive stable excitation. For engineering access, the integrated 100Base-TX port provides a direct TCP/IP path to a service computer. Legacy diagnostics are available through the RS-232 serial interface, which supports speeds up to 115 kBaud. When an SSI feedback device is used, signal integrity is maintained along cables up to 75 m, aided by the RJ12 encoder jack and adjustable clock timing.

Local machine signals are handled through the MD2 expansion, which offers 16 digital inputs and the same number of sourcing outputs while adding only 1 W to the controller’s internal load. These channels permit direct connection of sensors, valves, or interlock switches without external I/O cards. The resolver excitation is generated at 4 kHz, matching common motor transducers and supporting smooth position calculation across the full speed range. Physical connection to the drive stack is simplified by an RJ-45 8-pin plug on the S3 side, while the SSI option uses a separate RJ12 six-pin socket. These interfaces support motion feedback, axis coordination, and discrete machine control within a compact slot module.
