Product Description:

The CSH01.1C-PL-ENS-EN2-NNN-NN-S-NN-FW is a control section from Bosch Rexroth Indramat’s CSH Advanced Controllers series. As a plug-in module, it manages motion commands, communication links, and local digital I/O for IndraDrive power units used in automated machining cells, packaging lines, and material-handling axes. It supervises feedback processing and internal control functions so connected power sections can respond predictably to commanded motion. This role lets the controller coordinate axis behavior with upstream automation while keeping signal handling inside the drive platform.

It draws 7.5 W of base power from the backplane, yet the initial energizing phase can momentarily reach an inrush of 4 A, so cabinet fusing must tolerate that brief surge. Communication with the drive logic is handled through a parallel interface, and the external plug is a D-Sub 37 connector that carries the mixed-purpose lines. Thirty-two digital channels are present, arranged as 16 In / 16 Out, so simple sensors, interlocks, and output devices can be wired directly to the controller. For local serial communication, the integrated RS-232 port operates at up to 115 kBaud.

Sensor and actuator lines are powered directly from the control section. A regulated analog channel provides 5 V DC for potentiometer or reference outputs, and the stable supply supports downstream A/D conversion. The ENS encoder interface delivers 11.6 V DC at 500 mA with an input resistance of 120 ohms; its capture circuit accepts square-wave signals at up to 400 kHz, and each pulse can be stretched to a maximum of 100 ms for low-speed transducers. A second encoder rail, EN2, supplies 5.0 V DC at 350 mA and supports devices with load resistance down to 35 ohms. When field devices must be energized, the on-board relay contacts can switch up to 1 A, allowing direct control of small solenoids, pilot circuits, or indicator loads without external amplifiers.
