Product Description:

The CSH01.3C-PB-EN2-MA1-CCD-L2-S-NN-FW control section is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is intended for mounting inside an IndraDrive power unit, where it processes motion commands and fieldbus data for one drive axis in factory automation. By combining axis regulation, encoder evaluation, and functional safety on a single plug-in board, the module streamlines cabinet layouts and reduces wiring in multi-station production cells. Its plug-in format keeps the control electronics close to the power stage and feedback connections, which helps shorten internal signal paths inside the drive assembly.

This unit is configured for a single-axis drive, meaning its internal regulators and I/O map support one power section. Cross-communication through CCD lets multiple CSH controllers exchange position data without external fieldbus overhead. The integrated encoder interface is coded as EN2, which accepts EnDat 2.1, 1 Vpp, or 5 V TTL sensor formats, and the connected transducer is energized by a stabilized output of 5 V. Parameter access is available through an Ethernet-based engineering port, allowing communication over standard TCP/IP networks. Two MA1 analog channels, each with 2 inputs and 2 outputs, permit ±10 V command or feedback signals for process variables such as torque or tension.

Field-level integration is handled by the PROFIBUS master interface that reaches the plant bus through connector X30, while coordinated motion shutdown relies on the certified Safe Torque Off function. That safety path is energized at a nominal 24 V / 3 mA and enters the controller through a 9-pin female D-Sub. Parameter download or simple diagnostics can also be carried out through the built-in RS232 serial port. This arrangement lets the controller support plant communication, local access, and safety shutdown from the same module.
