Product Description:

The CSH01.1C-CO-ENS-NNN-NNN-NN-S-NN-FW is a motion-control logic module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into IndraDrive power sections and coordinates servo axes, discrete sensors, and fieldbus data flows inside automated machinery. Within an automation rack, this controller executes positioning, velocity, and sequence logic so that actuators follow programmed profiles while safety circuits and diagnostic channels remain synchronized. Because the module is installed directly in the drive platform, signal handling and axis control can be kept close together without requiring a separate standalone motion controller.

For local signal processing, the unit provides 1 analog input for voltage feedback such as potentiometer wipers, and it drives actuators through 2 analog outputs rated at 5 V up to 1 mA. Eleven onboard digital terminals accept 24 V field signals, and this group of 11 digital inputs draws only 3 mA per line to reduce sensor loading. Four configurable I/O points can be set as either inputs or outputs, which helps simplify panel wiring when signal requirements vary between machines. Two probe inputs capture edge-triggered events, and a relay with one normally open contact can switch external loads at 24 V and 1 A. The controller’s housekeeping consumption is 7.5 W, and its DC link sees an inrush of 4 A, so the incoming supply path must tolerate that brief surge.

Position capture is handled through the ENS encoder interface, whose differential receiver presents 120 ohms of input resistance and is powered from an internal 11.6 V source. The driver side can source 500 mA to external evaluation electronics, and TTL edges up to 400 kHz are accepted without pulse shortening. When used for measuring tasks, the unit registers pulses as narrow as 100 ms, which supports reliable detection of slow limit-switch signals as well as encoder markers. The fixed digital input load of 24 V, 3 mA remains constant across the full temperature range, which helps with current-budget planning for connected field devices.
