Product Description:

The CSH01.1C-SE-NNN-NNN-NNN-NN-S-NN-FW is a control section designed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It slides into an IndraDrive stack and provides axis-related computing power for coordinated motion tasks such as positioning, synchronizing, and speed regulation. Within an industrial automation cell, the unit links the drive to higher-level PLCs and field devices, translating network commands into deterministic current loops while collecting status data needed for preventive maintenance. Its modular format lets machine builders scale both single-axis and multi-axis configurations without redesigning peripheral wiring.

This section offers precision analog processing. Each voltage input presents an impedance of 160 kΩ, minimizing load on external sensors. Conversion granularity is 1.23 mV/inc on the inputs, while the feedback outputs resolve at 19.5 mV/inc, supporting closed-loop control of proportional valves or torque references. The current control loop refreshes every 125 µs, and the minimum SERCOS telegram time is 1000 µs, so motion data stay synchronous across multiple axes. A SERCOS II fiber ring forms the primary communication interface, and a standard control panel is available for local parameter entry. Basic logic demand is only 7.5 W, keeping cabinet heat low even when the safety technology option is omitted.

Discrete resources include four high-side outputs that can source up to 500 mA each for relays or brake solenoids. At power-up, the module withstands an inrush of 4 A lasting no longer than 100 ms, allowing small breakers to be used upstream. One form-A relay is integrated, and its contacts are rated at 30 VDC, 1 A for signaling tasks. Fast probing inputs achieve 1 µs edge accuracy and issue 4 µs capture pulses so position-latch events remain coherent with the active torque cycle. Probe edges, relay status, and digital outputs are timestamped on the SERCOS bus without requiring extra interface cards.
