Product Description:

The CSH01.1C-PL-ENS-NNN-NNN-L2-S-NN-FW is a single-axis control section from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It plugs into IndraDrive power sections and supplies motion commands, encoder evaluation, and field I/O needed for industrial automation tasks such as packaging axes or material-handling gantries. By combining drive regulation with integrated safety, the card reduces panel space and simplifies wiring for multi-motor assemblies.

This control section draws a base power of 7.5 W, so cabinet thermal load remains low during continuous operation. The encoder interface digitizes position data with 12-bit resolution and accepts incremental signals up to 500 kHz. A differential input of 120 ohms terminates the line to limit reflections. The sensor port supplies up to 500 mA at 11.6 V (typ) to power external encoders. A D-Sub 15-pin female connector carries these signals, while a separate D-Sub 37-pin parallel connector handles 16 input and 16 output channels for fast PLC-type tasks. TTL reference pulses can be processed at 400 kHz, enabling fine electronic gearing. When the drive first energizes, a 100 ms inrush pulse is permitted by the power stage.

Serial diagnostics use the RS-232 port, which supports data exchange rates up to 115 kBaud on cable runs as long as 15 m. The mandatory safety channel is the Safe Torque Off function, which removes gate power internally so the motor cannot generate torque. During line energization, the module can draw a typical inrush current of 4 A before settling to its steady-state demand. Combined with the D-Sub parallel I/O, the card’s 37-pin plug allows direct wiring to light curtains and sensors without extra interface boards, and the matching 16 transistor outputs can switch valves or contactors that require synchronous reaction times.
