Product Description:

The CSH01.1C-NN-ENS-NNN-MD2-NN-S-NN-FW is a control section module manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on IndraDrive power sections, it executes motion algorithms, handles field signal conditioning, and coordinates feedback loops in automated assembly lines, packaging stations, and material-handling cells. By integrating signal acquisition, encoder evaluation, and operator interaction in one plug-in card, the unit concentrates the deterministic control functions required to synchronize multiple servo axes within an industrial automation environment.

The processing chain begins with a 12-bit analog-to-digital converter that resolves sensor voltages into 4,096 numerical increments for precise loop updates. Rotary encoders wired to the D-Sub interface are furnished with a regulated supply of 12 V, and a maximum sourcing capability of 500 mA supports transducers that include internal LED drivers or level shifters. The MD2 expansion adds 16 digital inputs for on/off states such as limit switches, and these events can be diagnosed or parameterized through the integrated RS232 maintenance port, eliminating the need for an external gateway.

Complementing the input side, each MD2 channel delivers up to 3 mA of sink current, while discrete outputs can switch loads as high as 0.5 A so contactors or stack lights can be driven directly from the controller. High-frequency edge recognition is maintained by a maximum TTL capture rate of 400 kHz, letting the card monitor fine-pitch encoders on fast spindle axes without loss of counts. For resolver-style sine signals, an internal termination of 120 ohms matches cable impedance and minimizes reflections, supporting reliable feedback over extended cable runs in electrically noisy plant environments.
