Product Description:

The CSH01.2C-PB-EN1-MEM-CCD-NN-S-NN-FW is a compact motion and logic controller released by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the command section inside IndraDrive amplifier assemblies, executing axis control, fieldbus communication, and encoder processing for automated machinery. By combining PLC functionality with hardware interfaces for drives and feedback devices, the unit coordinates position loops and synchronizes multi-axis systems in industrial automation cells. This arrangement allows one control section to manage motion commands and feedback handling for tightly coordinated machine operation.

This controller operates from a supply of DC 24 V, and its base power demand is only 8.5 W, which helps limit cabinet heat rise. At startup, the electronics draw an inrush current of 4 A, so the supply circuit must tolerate that brief peak. Cross-communication to neighboring drive sections is handled through SERCOS III Master, supporting deterministic real-time data exchange. For plant-level networks, the module provides a PROFIBUS-DP interface routed to a D-sub, 9-pin female connector. Engineering access is available through 100Base-TX Ethernet on an RJ-45, 8-pin port, which allows parameter access without removing the front cover. Resolver and HSF feedback signals are processed internally, while the analog path uses a 100 kHz cutoff to reject noise outside that band. A resolver carrier of 4 kHz supplies the transformer windings.

For drive simulators and test stands, the integrated encoder emulation can issue incremental and SSI signals at up to 1 MHz, allowing downstream devices to follow a virtual axis without additional hardware. These differential pulses can travel over shielded cable runs as long as 40 m before regeneration is needed. When converter mode is active, the HSF path keeps its digital width at 12-bit, so each analog cycle is reproduced accurately. Safety watchdog logic also limits every generated pulse to a maximum width of 100 ms, which helps prevent latch-up in receiving counters.
