Product Description:

Bosch Rexroth Indramat designs the CSH01.1C-PB-ENS-EN1-MD1-NN-S-NN-FW as a component within its CSH Advanced Controllers series. The card functions as a single-axis motion controller that coordinates servo drive tasks, fieldbus communication, and local I/O processing in automated machinery. It combines axis supervision, signal handling, and communication functions in one control platform for compact automation layouts.

It draws a base power of 7.5 W, allowing low standby consumption while the processing core supervises axis commands. Field integration is handled through PROFIBUS-DP; the interface supports a maximum data rate of 12 MBaud for deterministic exchange with PLC masters, and a service port based on RS232 is present for parameter transfer. Position feedback can be evaluated through the first encoder channel configured for standard encoder evaluation, and a second channel accepts resolver or high-speed feedback signals. An I/O extension option supplies additional digital points, and the ENS section delivers a regulated output of 11.6 VDC at up to 500 mA for external sensors. No integrated safety technology is installed, so safety functions must be provided by other system components.

Power-up demands are limited by a maximum inrush current of 4 A, which helps reduce supply-side surge during startup. The MD1 module exposes 12 x 24 V inputs for limit switches or probes and 8 x 24 V transistor outputs for contactors or indicator lamps. Each output pulse can be stretched to a maximum width of 100 ms, while the probe capture circuit responds within 1 µs, supporting precise registration moves and print-mark detection. A digital I/O extension bus is available for additional points when machine layouts expand, and this helps the controller adapt to applications that need more sensors or actuators without changing its basic control role.
