Product Description:

The CSH01.1C-ET-EN2-NNN-NNN-L2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for single-axis drive tasks, it serves as the central processing unit that links feedback devices, fieldbus networks, and safety circuits inside an IndraDrive system. Within an automation cell, it processes motion commands, supervises torque shutoff functions, and routes analog or digital I/O to the associated power stage. This arrangement allows one compact module to manage command handling, feedback evaluation, and interface coordination for the connected axis.

The controller accepts an analog reference of ±10 V so a PLC can deliver speed or torque commands directly, and the matching analog output supplies 5 V / 1 mA for status or follower signals. Eight digital inputs are wired for 24 V / 3 mA, while four transistor outputs switch up to 24 V / 0.5 A for contactors or indicator lamps. Network access is provided through Multi-Ethernet, allowing configuration for SERCOS III, EtherNet/IP, PROFINET, or EtherCAT without hardware changes. Motor position data is read over the EnDat 2.1 / 1 Vpp / 5 V TTL interface, giving the drive accurate incremental and absolute feedback. Its front panel is the standard variant with membrane keys and diagnostic LEDs, and a MultiMediaCard slot stores user parameters for local use. The built-in indicators provide direct visual status information at the unit.

A relay channel rated at DC 24 V / 1 A is included for galvanically isolated fault signaling, and the integrated safety circuit executes Safe Torque Off through a 9-pin D-Sub connector tied to external emergency-stop loops. For service access, the RS232 serial interface is available on a MiniDin 8-pin female port and reaches a maximum transfer rate of 115 kBaud over cable lengths up to 15 m. This serial connection provides a separate path for diagnostics when the main network is reserved for real-time control. The auxiliary links work alongside the Ethernet port without changing the controller’s primary motion-control role.
