Product Description:
The CSH01.1C-NN-EN2-ENS-MD2-S2-S-NN-FW is an automation controller produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. This module is intended to be installed in an IndraDrive cabinet alongside power inverters, where it generates axis commands, evaluates encoder feedback, and supervises safety states. By handling these tasks locally, the board reduces fieldbus load and allows deterministic positioning and speed regulation in packaging machines, material-handling lines, and general motion platforms. It operates as the motion-control section of the drive assembly, while the associated inverter handles power conversion to the motor.
Its signal conditioning section accepts an analog reference of ±10 V, while the integrated digital-to-analog converter provides a feedback channel from 0 to +5 V for process values such as torque or velocity. Normal operation draws only 7.5 W from the backplane supply, so cabinet thermal load remains low. Each fast transistor output can source up to 500 mA, and the MD2 expansion adds 16 opto-isolated digital inputs for limit switches or sensor flags. For electromechanical actuators, the onboard relay is rated at DC 24 V / 1 A, allowing direct control of contactors or brake solenoids without an external interposing relay.
The second encoder slot supports EnDat 2.1, 1 Vpp, and 5 V TTL formats, while the first slot performs standard incremental evaluation; both use an EN2 input whose twisted-pair run may extend to 75 m before signal regeneration is required. This interface is energized by a regulated 5 V rail (±5%) and a separate ENS line that supplies 11.6 V at up to 500 mA for reference marker sensors. Command diagnostics are handled through an RS-232 channel selectable from 9.6 to 115 kBaud. The controller also provides 16 digital outputs on the MD2 board, a 24 V SSI supply for absolute encoders, and the Safe Motion package that monitors velocity and position independently of the main CPU. Separate encoder, SSI, and digital I/O channels let the controller interface with external encoders, sensors, and switching signals.
