Product Description:

The CSH01.1C-ET-EN2-NNN-NNN-L1-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for use in the CSH Advanced Controllers series. Installed in an IndraDrive power unit, this module supplies motion control logic, axis feedback processing, and fieldbus connectivity so a servo system can execute position, velocity, and torque loops under centralized supervision. Its role in industrial automation is to translate program commands and network data into synchronized drive signals, allowing multi-axis machines to maintain repeatable cycles and coordinated trajectories.

The module draws a base idle power of 7.5 W, so heat dissipation in standby is limited and cabinet ventilation can be sized accordingly. Command and diagnostic traffic moves through a Multi-Ethernet interface, giving the drive access to protocols such as EtherNet/IP and PROFINET without additional option cards. Physical layer signaling complies with the 100Base-TX standard and therefore uses conventional Cat-5e cabling over twisted-pair copper. Control electronics are supplied from the drive bus at 24 V DC, and the on-board transistor outputs can source up to 500 mA to actuate relays, contactors, or indicator lamps located in the machine wiring harness.

Position information is handled by the En2 channel, whose signal conditioning supports EnDat 2.1 encoders and both incremental 1 Vpp and 5 V TTL formats. The port maintains reliable drive-line termination by requiring a 35 Ohm load, while the associated sensor power rail remains regulated at 5.0 V DC with a maximum draw of 350 mA. Two form-C relays on the logic board can switch up to 1 A at 30 V DC for readiness flags. The integrated safety layer enforces a Starting Lockout, so the axis cannot energize until all enable conditions and the 24 V acknowledge circuit are present.
