Product Description:

The CSH01.1C-S3-ENS-EN2-NNN-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in an IndraDrive servo inverter, the module provides the computational layer that handles axis interpolation, real-time fieldbus exchange, and encoder processing so that multi-axis machinery maintains position and torque accuracy during automated production tasks. It serves as a flexible platform that can be reparameterized for packaging lines, gantry robots, or conveyor applications without changing the power stage.

Signal flexibility is provided through an analog command channel that accepts ±10 V, permitting both unipolar and bipolar reference signals from supervisory PLCs. The board returns measured values through a buffered output rated at 5 V / 1 mA, which is suitable for high-impedance monitoring devices. High-speed deterministic traffic is carried over SERCOS III; the controller connects to the 100Base-TX ring through an RJ-45, 8-pin socket and supports cycle times suited to sub-millisecond position loops. Single-turn and multi-turn feedback from IndraDyn motors or Hiperface transducers are accepted on the first encoder port, while EnDat 2.1, 1 Vpp, or 5 V TTL formats are processed on the second. The digital pulse input channel remains reliable with pulse widths up to 100 ms, and all logic circuits operate from a stabilized DC 24 V source supplied by the drive power module.

Total steady-state dissipation stays at only 7.5 W, which eases cabinet ventilation requirements. Safety Technology I/O is provided through a D-Sub 9 female connector, where each channel is continuously diagnosed and the solid-state safe output can switch up to 24 V / 0.5 A to interlock contactors or light curtains. During power-up, the internal filter capacitors draw a typical inrush current of 4 A, which should be considered when sizing the auxiliary supply breakers. Additional safety functions are available through relay contacts rated at DC 24 V / 1 A.
