Product Description:
The CSH01.1C-NN-EN2-NNN-MD2-S1-S-NN-FW is an advanced control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power module, it orchestrates motion axes by processing encoder feedback, furnishing digital I/O, and issuing real-time drive commands that synchronize motors, sensors, and actuators in industrial automation lines. This control section serves as the logic and interface layer of the drive, linking field signals with closed-loop motion functions inside a compact module. It is suited for applications that require coordinated axis behavior, consistent feedback handling, and direct integration with machine wiring.
The EN2 encoder interface draws 350 mA from a dedicated 5.0 V rail and tolerates a load resistance of 35 Ω, allowing reliable differential signal reception from position transducers. At power-up, the control section presents an inrush of 4 A, which is relevant when sizing cabinet fusing and auxiliary supplies. Total internal demand stabilizes at 7.5 W during normal operation, which helps limit thermal rise inside compact enclosures. The EN2 sense lines can be clocked by an SSI channel that reaches a maximum of 1000 kHz, supporting fast absolute position updates for high-speed machinery. A maximum pulse width of 100 ms is supported for reference mark or latch inputs, so longer dwell signals can be captured without a timeout condition.
The MD2 expansion provides 16 digital inputs and an equal number of outputs, arranged in two input and four output groups so machine functions can be separated across different signal sections. Encoder sense cable length may extend up to 75 m when correct shielding is used, permitting remote feedback devices on gantries or transfer lines. The S1 terminal block distributes a control voltage of 24 VDC. Each transistor output can deliver 0.5 A, while the combined I/O rail is limited to 1.6 A and the relay contact is rated at 1 A for pilot-duty loads. These limits determine how many indicators, contactors, or brakes can be powered directly from the controller before external interface devices are needed.
