Product Description:

The CSH01.1C-PB-EN1-NNN-CCD-S1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is a plug-in motion controller that supervises axis positioning, fieldbus exchange, and safety logic inside IndraDrive modular systems. In industrial automation, this board bridges higher-level PLC orders to the servo power module, interprets encoder feedback, and issues velocity or torque commands so conveyors, pick-and-place arms, or machining spindles follow programmed profiles. By combining communication ports, analog channels, and encoder supplies on one board, it reduces cabinet wiring and simplifies setup in multi-axis machines.

The board provides 1 differential analog input to accept a precision reference such as an external torque setpoint, while 2 analog outputs can retransmit speed or current values to a supervisory control loop. For serial diagnostics, the board uses EIA-RS485 bus signaling, which helps protect data lines from noise over long cable runs. Real-time motion commands from the PLC arrive through the board’s PROFIBUS-DP master channel, allowing fast cyclic exchange of drive parameters. For parameter access or plant network connectivity, the CCD ports use 10/100Base-T Ethernet and are presented on dual RJ45 sockets, so the drive can be daisy-chained without additional switches. These interfaces support deterministic motion control and standard TCP/IP service functions.

The encoder side supplies 8 V DC at up to 250 mA to power HSF transducers, and its resolver track is excited at 4 kHz to obtain noise-resistant position data. A 9-pin D-Sub female connector on the front panel carries the PROFIBUS cable shield directly to the housing, which helps minimize EMC issues. Safety circuits use the same connector style, and their inputs operate at 24 V / 3 mA, while solid-state outputs can source 24 V / 0.5 A to external relays. The keyed connectors help prevent wiring errors during installation.
