Product Description:

The CSH01.1C-PB-EN1-ENS-NNN-S1-S-NN-FW is a motion-logic controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power sections, it coordinates command processing, fieldbus exchange, and encoder feedback for servo axes used in automated machinery. By combining bus repeater circuitry, dual encoder channels, and dedicated safety I/O, the board serves as the central interface between higher-level PLCs and the drive’s power electronics.

Control communication is via PROFIBUS-DP, and the onboard repeater draws 75 mA from a 5 V rail to regenerate telegrams across the drive rack. Resolver channel EN1 operates at a 4 kHz carrier frequency and energizes the transducer with 18.2 Vpp, accepting feedback through the Resolver / HSF interface when standard motor resolvers are used. A second encoder port supports IndraDyn / HIPERFACE / 1 Vpp signals, giving the controller flexibility to process absolute or incremental feedback. For this channel, the board can source 500 mA, while an additional 11.6 V supply feeds encoders that need constant excitation. Together, these electrical limits set the sensor power budget, and the dual-channel architecture lets the control loop use fine-resolution or coarse-resolution data without rewiring.

Input circuitry presents 120 Ω termination so incoming differential pairs are properly matched, which helps minimize signal reflections on long cable runs. The service port follows the RS-232 standard; it supports cables up to 15 m and a top transfer rate of 115 kBaud, enabling parameter uploads during setup. The S1 terminal block brings a 24 V logic line rated at 3 mA for state sensing and a 24 V transistor output rated at 0.5 A for actuator driving, while the integrated Safety Technology I/O option permits hardware-level shutdown of connected axes. These secondary resources allow the controller to manage status lamps, interlocks, and emergency chains without adding external interface modules.
