Product Description:

The CSH01.1C-PB-ENS-EN2-MD1-L1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive cabinet, this module furnishes processor power, feedback evaluation, and fieldbus connectivity needed to synchronize multiple axes and peripheral actuators in automated assembly lines, packaging machines, and material-handling cells. It translates motion commands from a higher-level PLC into precise drive signals while continuously supervising encoder data and integrated safety channels.

Communication with the plant network is handled over the PROFIBUS-DP interface, permitting cyclic setpoint and diagnostic exchange through a 9-pin female port. During operation, the board draws a base load of only 7.5 W, so cabinet ventilation demands remain moderate. The analog monitor output is rated at 5 V / 1 mA, giving a non-loading test point for velocity or torque traces. For secondary feedback, the En2 port delivers 5 V at 350 mA and tolerates a channel impedance of 35 ohms while transferring EnDat 2.1, 1 Vpp, or 5 V TTL signals to the drive. Motion-related I/O resides on the MD1 header, which carries 12 digital inputs and 8 digital outputs to external sensors and actuators.

Safety wiring terminates on a 9-pin female connector that accepts inputs at 24 V / 3 mA and returns an acknowledge line capable of switching DC 24 V / 1 A. The same rating applies to the built-in relay contacts used for drive-ready signaling. An auxiliary encoder supply labeled ENS provides 12 V so multiturn encoders stay powered during logic-off states. MD1 signals can be checked with standard breakout leads because the header follows the D-Sub, 25-pin format. When the controller detects a critical condition, it activates a starting lockout compliant with Stop Category 0, immediately removing motor power without controlled deceleration.
