Product Description:

The CSH01.1C-PB-ENS-NNN-NNN-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on a power module, it acts as the command layer that processes motion profiles, interfaces with feedback devices, and exchanges data with higher-level PLCs in automated cells. Its onboard control functions execute interpolation, diagnostic, and safety routines so multiple axes can be driven from a single logic platform without external supervisory hardware.

The module conditions field signals through isolated analog and digital channels. Each differential analog input accepts a span of ±10 V and is buffered by a 160 kΩ input resistance to limit loading on transducers. A rear-panel DAC provides a reference of 5 V / 1 mA for drive setpoint generation. Discrete command lines are recognized when they reach 24 V / 3 mA, while actuator coils can be driven directly from the sourcing outputs that deliver 24 V / 0.5 A. Cycle-to-cycle coordination with neighboring controllers is handled over PROFIBUS, and the logic board itself draws only 7.5 W from the shared DC bus. A TTL capture channel samples edge-triggered feedback up to 400 kHz so fine-pitch encoders and proximity probes can be evaluated without aliasing.

Encoder support is provided through a D-Sub 15-pin connector, and the evaluation circuit is set to standard mode for incremental or absolute formats. The sensor port sources 500 mA at 11.6 V, eliminating the need for an external supply. A controlled inrush of 4 A protects cabinet breakers when the rack is energized, and the relay interface can switch loads up to 24 V DC / 1 A for brake or contactor control. Time-critical latching is aided by a maximum pulse width acceptance of 100 ms, while asynchronous diagnostics stream over the serial maintenance port at up to 115 kBaud.
