Product Description:

The CSH01.1C-SE-ENS-EN1-MA1-NN-S-NN-FW is a motion-control master from Bosch Rexroth Indramat, supplied within the CSH Advanced Controllers series. It occupies the command layer of multi-axis drive systems, exchanging real-time setpoints and feedback with servo inverters so that coordinated positioning, velocity, and process timing can be executed in industrial automation cells. The unit is intended for centralized control tasks in machines that require synchronized axis behavior, repeatable motion sequences, and stable communication between the control section and the connected drives. It also supports coordinated machine functions where several drive axes must respond together during indexing, transfer, or position correction.

This controller links to drives over SERCOS II, a fiber-optic ring that furnishes deterministic 2 ms cycle times for synchronized motion. For service access, it carries a 100Base-TX Ethernet port that supports parameter adjustment and diagnostics. Its digital output stage can source up to 500 mA, letting it actuate indicator lamps or small relays directly. The internal excitation for the En1 encoder connector is generated at 4 kHz to maintain clean sine-cosine feedback signals at high motor speeds. The MA1 module’s differential input pair presents a high input resistance of 1000 kΩ, minimizing loading on external analog sensors while allowing full-range acquisition of process variables.

Two encoder supply rails are provided: channel 1 delivers 12 V for IndraDyn or Hiperface transducers, and channel 2 outputs 8 VDC for resolver-based devices. Analog input bandwidth is limited to 1 kHz, which filters high-frequency noise while still passing speed reference signals accurately, and the corresponding outputs drive 1 kΩ loads with 5 mV resolution per increment. For discrete power switching, a form-C relay is integrated and rated at 30 VDC, 1 A, permitting isolation of brake valves or contactor coils. Additional interfaces include an RS-232 maintenance port that supports cable runs up to 15 m and two unmodulated analog outputs for actuator command voltages. These interfaces allow the controller to exchange service data and supply straightforward analog command signals to connected machine devices.
