Product Description:

The CSH01.1C-PB-ENS-EN2-MEM-L2-S-NN-FW is a control section from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Installed in an IndraDrive drive stack, it provides axis monitoring, fieldbus communication, and integrated safety for factory automation equipment. Through its PROFIBUS master channel, the unit exchanges cyclic data with PLCs, while the Safe Torque Off function disables power modules when a stop command is issued. This arrangement allows motion systems to support Category 3 or Category 4 safety architectures when the surrounding system is designed accordingly.

This controller has two differential analog inputs that accept signals in the ±10 V range and present an input impedance of 160 kOhm, so external transducers see only a minimal load. Four transistor digital outputs are rated at 24 V / 0.5 A, allowing direct actuation of contactors or indicator lamps. The housing is 49.5 mm wide and 103 mm deep, which helps save cabinet space, while the overall height is 241 mm for compatibility with standard IndraDrive power sections. Encoder Interface 1 supports IndraDyn, Hiperface, 1 Vpp, or TTL feedback, and Encoder Interface 2 supports EnDat 2.1, 1 Vpp, or TTL signals. The module also outputs position data in SSI format, allowing downstream devices to read the same axis position without an additional transducer.

Secondary encoder supply rails are also provided. En2 delivers a regulated 5.0 VDC with a maximum load of 350 mA, while Ens supplies 11.6 VDC up to 500 mA for higher-power multi-turn sensors. Both rails support absolute and incremental encoder emulation, which helps maintain deterministic feedback when the drive shares position information with external motion controllers. The remaining I/O channels use the controller’s 24-bit internal resolution, and the compact steel enclosure supports electromagnetic compatibility without additional shielding hardware.
