The Bosch Rexroth Indramat CSH01.2C-PL-ENS-EN2-CCD-NN-S-NN-FW belongs to the CSH Advanced Controllers series and functions as a pluggable motion-control card for IndraDrive platforms. It supervises axis positioning, manages local inputs and outputs, and conditions encoder signals so integrated machines maintain coordinated movement during automated production. Its role within the drive system is to process motion commands and feedback signals so the connected axis can respond accurately during continuous machine operation.

This controller is powered from a system rail of 24 V DC. It accepts digital commands at 24 V / 3 mA and can drive field devices with source capability up to 24 V / 0.5 A. The analog front end reads process variables across a ±10 V span and issues control voltages from 0 to 5 V for actuators such as proportional valves. A parallel interface links the board directly to machine logic, while Encoder Interface 1 processes IndraDyn or HIPERFACE feedback in 1 Vpp format and Encoder Interface 2 handles EnDat 2.1, 1 Vpp, or 5 V TTL signals. Separate header pins provide 5.0 V DC at 350 mA for En2 feedback electronics and 11.6 V DC at 500 mA for Ens sensor rails, which reduces the need for external auxiliary power.

During power-up, the module draws an inrush current of 4 A, yet steady consumption is limited to 8.5 W, which helps reduce heat inside the control cabinet. Deterministic cross-device traffic is carried on SERCOS III, and output drivers can sustain a pulse width of 100 ms so mechanical relays can reach full travel. The base power supply, inrush limit, and dedicated En2 and Ens outputs help keep low-voltage buses stable while high-resolution encoder data and analog references are updated during operation.
