Product Description:

The Bosch Rexroth Indramat CSH01.1C-SE-EN1-NNN-MA1-S2-S-XP-FW is a control section in the CSH Advanced Controllers series. Installed in an IndraDrive stack, it handles axis coordination, parameter processing, and safety supervision for servo drives used in packaging, handling, and machining equipment. The card combines fieldbus links, feedback evaluation, and analog I/O in one slot, providing the control logic needed for accurate velocity, position, and torque regulation across multi-axis automation cells.

Internal power consumption is limited to 7.5 W, so the unit adds little thermal load inside a crowded drive cabinet. Command exchange with the inverter stack occurs over SERCOS II, a deterministic fiber-optic bus that maintains synchronized cycle times. The encoder connector supports resolver or Hiperface signals and delivers a regulated supply of 8 V DC to the sensor electronics. Setup and diagnostics can be performed through the RJ45 service port that operates on 100Base-TX, allowing parameter data to be transferred quickly through standard Ethernet tools. The MA1 analog option provides two input channels with a resolution of 12-bit for speed or torque commands, and two output channels that can source up to 10 mA each for external indicators or control valves. A load of 1 kΩ on the outputs preserves full linearity across the programmed range.

The resolver interface excites the position sensor with 18.2 Vpp at 4 kHz, allowing accurate angle evaluation without external line drivers. Safe Motion functionality adds certified stop and limited-speed modes that operate independently of the primary PLC, which helps retain drive-level safety handling during machine operation. Network throughput reaches 16 MBaud on the SERCOS ring, supporting rapid position updates when multiple axes share the bus. A legacy RS232 maintenance port also supports service access when Ethernet tools are unavailable, which is useful on existing installations that still rely on serial connections.
