Product Description:

The CSH01.2C-CO-EN2-EN1-CCD-S1-S-NN-FW is a plug-in control section in the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Installed on an IndraDrive power base, it coordinates servo axis commands, handles fieldbus traffic, and streams diagnostic data for automated production cells. By integrating encoder inputs, cross-communication hardware, and an engineering port, the module serves as the central logic element for motion control and direct status monitoring from a PC or PLC. This arrangement keeps the control functions close to the power section and supports compact multi-axis cabinet layouts.

The unit draws a base power of 8.5 W, which helps limit cabinet heat while sustaining internal logic. On the Co expansion slot, a 124 ohm bus terminator matches line impedance, and wiring lands on a 5-pole spring terminal. Ethernet cross-communication follows IEEE 802.3, allowing deterministic data exchange between adjacent control sections. The engineering interface uses 100Base-TX signaling and is presented on an 8-pin RJ-45 port, so standard CAT5e cables can be used. When control voltage is applied, an inrush current of 4 A occurs briefly, so the supply must tolerate that peak. The internal watchdog can issue fault pulses up to 100 ms wide, which supports orderly shutdown behavior if the control section detects a critical condition.

Motion feedback links are divided across two encoder channels. EN1 excites resolver windings with 8.0 V at 4 kHz, while EN2 supplies 5.0 V at 350 mA and permits cable runs up to 75 m, which suits remote feedback devices such as linear scales. The engineering port accepts cables up to 100 m without repeaters while maintaining full throughput. The S1 diagnostic header uses a female D-Sub 9-pin connector and can source up to 0.5 A for status lamps or test loads. These electrical limits help keep feedback, communication, and auxiliary power stable throughout the drive system.
