Product Description:

The CSH01.3C-PB-ENS-NNN-CCD-L2-S-NN-FW is a control section supplied by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a programmable drive controller module, it coordinates motion tasks and peripheral signals inside multi-axis IndraDrive systems. It manages command handling, feedback processing, and signal exchange between the power section and higher-level automation hardware. This arrangement helps the drive system keep axis behavior synchronized during positioning, speed regulation, and general machine sequencing. It is intended for applications where several axes and peripheral devices must exchange data in a coordinated manner.

This unit communicates over the PROFIBUS-DP fieldbus, so cyclic setpoints and diagnostic data travel on a widely adopted 12 Mbit/s bus. Internal losses remain low because total power consumption is only 8.5 W. Encoders tied to the module receive a regulated supply of 11.6 V at up to 500 mA, allowing absolute and incremental feedback devices to power directly from the controller. That arrangement lets compatible feedback devices operate without a separate external supply in the cabinet. High-speed position latching is supported through TTL channels that accept pulse streams up to 400 kHz, preserving encoder resolution at elevated speeds. The module can therefore handle bus traffic and local feedback tasks in the same control section without requiring separate interface hardware.

The integrated safety architecture provides Safe Torque Off, a hardware cut that silences gate drives without relying on software intervention. STO command lines monitor the control-voltage domain; the inputs sink just 3 mA, while the redundant relay contacts can switch 1 A on that circuit to satisfy external enable loops. Startup current is limited to 4 A for a maximum of 100 ms, which keeps the power-on demand brief. Once running, the logic section operates on a stable 24 V supply. Separate outputs forward that same voltage to interlock circuitry for straightforward integration with external safety chains.
