Product Description:

The CSH01.3C-ET-ENS-EN1-CCD-NN-S-NN-FW is a control section module built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive controller stack, the card provides the processing and interface resources that link motion axes with higher-level control networks in automated production lines. Within an automation cell, it converts drive feedback, manages fieldbus telegrams, and supervises digital and analog signals so the connected power stage can execute precise torque, speed, and position commands.

The analog section supplies one voltage channel and one current channel. The current channel can deliver 1 mA, while the complementary voltage output is fixed at 5 V; both can be used as reference setpoints for external amplifiers or sensors. Network exchange is accomplished through Multi-Ethernet, allowing the same port to negotiate Sercos III, EtherNet/IP, Profinet IO, or EtherCAT without hardware changes. For discrete actuation, the board carries eight transistor outputs; each line can draw up to 500 mA, and the combined group is limited to 1000 mA, which helps protect the onboard driver transistors from thermal overload. A relay contact rated for 1 A at DC 24 V is included for safety-related interlocks, and two encoder connectors accept incremental or resolver feedback for real-time position evaluation.

The dedicated EN1 channel works with resolver transducers at a 4 kHz carrier frequency and senses rotor position with an excitation level of 18.2 Vpp to maintain noise-tolerant feedback over long motor leads. An integrated Ethernet link rated for 100Base-TX supports cable runs to the plant switch up to 100 m, which matches typical cabinet-to-network distances. When the drive stack uses the optional cross-communication card, this unit serves in the master role and forwards global setpoints to peer axes through deterministic backplane messaging. A separate RS232 port remains available for service diagnostics without disturbing real-time traffic.
