Product Description:
The CSH01.1C-PB-ENS-NNN-MEM-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for integration into the CSH Advanced Controllers series used in IndraDrive automation platforms. As a motion and I/O coordinator, it occupies one slot of a multi-axis drive stack. It processes fieldbus signals, encoder feedback, and safety data so the surrounding servo inverters can execute precise speed, torque, or position commands. This arrangement lets the control section handle communication and feedback tasks separately from the adjacent power electronics.
This unit draws only 7.5 W from the DC bus, so cabinet heat rise stays minimal even when all logic channels are active. Its main fieldbus interface is PROFIBUS-DP, enabling cyclic exchange of setpoints and diagnostic words with PLCs over a single shielded pair. That interface supports coordinated control across networked machine axes. The encoder emulation path is galvanically isolated, preventing ground loops between the drive and downstream measurement electronics. A service port based on RS232 supports setup tasks, and data transfer on this port can be selected up to 115 kBaud. For machine-level risk reduction, a dedicated hardware channel implements Safe Torque Off, cutting power devices in less than a millisecond when an external safety relay opens the contact. The controller accepts encoder plugs through a D-Sub 15-pin female header, interprets them with a standard evaluation algorithm, and forwards position words to the axis processor.
The encoder supply rail provides 12 V to power external sensors, and its emulation output can deliver absolute and incremental formats at the same time, allowing mixed feedback schemes on the machine. STO logic arrives on a separate 9-pin female D-Sub connector, with each channel sensing a 24 V / 3 mA signal to meet typical safety relay currents. When the controller receives valid inputs, it enables normal inverter gating. If the signal disappears, the unit blocks drive output without affecting upstream communication lines.
