Product Description:

The CSH01.2C-SE-EN2-EN2-CCD-NN-S-FW is a configurable control section supplied by Bosch Rexroth Indramat and assigned to the CSH Advanced Controllers series. Installed inside a Rexroth drive, this module executes axis control, manages fieldbus exchanges, and interfaces with encoder feedback to direct servo or spindle hardware in automated machinery. It serves as the command layer that interprets motion commands, calculates setpoints, and forwards them to the power stage so production lines and robots maintain synchronized movement.

To minimize cabinet load, the unit draws a base power of 8.5 W while idle. For deterministic motion profiles, it links to the drive bus through the SERCOS II interface, and network arbitration follows IEEE 802.3 rules because the cross-communication channel is configured as Master. A 100Base-TX engineering port allows Ethernet-based setup without disturbing cyclic data. Up to 500 mA can be sourced from the digital outputs to actuate relays or sensors directly. Position feedback is accepted through the multi-protocol encoder input, and the first format, EnDat 2.1, shares the terminal with 1 Vpp and 5 V TTL signals. The encoder supply is regulated internally at 5 V, and a standard control panel on the front provides local jogging, status LEDs, and access to stored parameters.

During power-up, the module withstands an inrush of 4 A before settling to its nominal demand, and its watchdog issues a ready pulse that lasts 100 ms so downstream devices can synchronize start-up. Diagnostic servicing is aided by an RS-232 fallback link that supports one node running at 115 kBaud. When high-speed coordination is required, the Sercos channel transmits real-time telegrams at 16 MBaud. No integrated safety technology is present, so emergency-stop logic must be implemented in external hardware.
