Product Description:

The CSH01.1C-ET-EN1-NNN-NNN-L1-S-NN-FW is a drive controller section manufactured by Bosch Rexroth Indramat and assigned to the CSH Advanced Controllers series. Installed inside IndraDrive inverters, it supervises motor current, speed, and position for compact servo axes used in packaging, handling, and machining cells. The module receives high-level motion commands, processes feedback from resolvers or HSF encoders, and issues precise gate signals to the power stage, so it serves as the core of closed-loop regulation in modern automation lines.

This section supports a single-axis configuration and links to supervisory equipment through Multi-Ethernet ports that accept several protocol stacks without extra hardware. Current is recalculated every 125 µs, giving tight torque control for fast indexing duties. One analog input and two analog outputs allow drive-level data exchange, and the outputs step in 19.5 mV per increment for fine reference generation. Digital outputs can sink or source up to 500 mA, allowing the board to switch contactors or status lamps directly. Feedback enters through resolver and HSF interfaces, and the excitation lines deliver 8 V to the transducer to maintain signal integrity over long motor cables. A single-line display on the front assists with local setup and diagnostics.

Network timing is synchronized on the 100Base-TX physical layer, so telegrams share the same wiring used for standard industrial Ethernet. When power is applied, the module draws an inrush of 4 A, and once energized its logic circuitry typically dissipates 7.5 W, which helps reduce thermal load in crowded cabinets. The control electronics are enabled by an external 24 V / 3 mA L1 signal, and a watchdog channel can stretch the output pulses up to 100 ms to accommodate slower relays. One floating make contact rated 1 N/O is available for ready or fault indication.
