Product Description:

The CSH01.1C-PB-ENS-ENS-CCD-S1-S-NN-FW is a control section module manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Housed inside an IndraDrive power section, this board provides axis command processing, network bridging, and integrated safety supervision for automated machinery. It accepts encoder feedback directly and exports coordinated motion profiles to connected drive inverters, reducing the need for external PLC cards inside compact machine cabinets. The module is suited for drive applications that require feedback handling, fieldbus communication, and safety monitoring within one assembly.

It draws logic power from a 24 V DC control supply that feeds the microprocessor core, opto-isolated inputs, and watchdog circuits. When that rail is first applied, an inrush current of 4 A can occur, so cabinet fusing and wiring must tolerate the brief surge. Once running, total power consumption stabilizes at 23.5 W, which helps limit heat buildup in densely packed enclosures. The RS-232 diagnostic port supports a single node and operates over cable lengths of up to 15 m with transfer speeds up to 115 kBaud, allowing parameter uploads without removing the module. The input-capture channel accommodates trigger events with a maximum pulse width of 100 ms, making it suitable for slower inductive or mechanical probes used on heavy equipment.

For high-speed edge detection, the dedicated probe line recognizes pulses as short as 4 µs. Motion data are exchanged between multiple drives through the module’s role as a SERCOS III Master, while machine-level coordination with PLCs is handled on the PROFIBUS-DP fieldbus. Safety resources include solid-state outputs rated at 24 V / 0.5 A that feed external contactors, backed by a D-Sub 9 safety connector and dual ENS encoder inputs for redundant position monitoring. The redundant encoder paths support safety functions that rely on cross-checking position information from separate feedback channels.
