Product Description:

The CSH01.1C-CO-EN2-MA1-MD1-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Within an IndraDrive power unit, this section governs servo axes, handles fieldbus communication, and processes local I/O needed for coordinated motion. By combining bus interfacing, encoder evaluation, and analog expansion on one plug-in module, the product provides compact command functionality for industrial automation cells that demand deterministic drive control and flexible signal handling.

Communication is routed through a 5-pin spring terminal that carries either CANopen or DeviceNet traffic. When operated on the former network, the node table can extend to 127 devices, while a DeviceNet topology permits up to 64 addressed stations. Four configurable local I/O points allow status bits or handshake lines to be mapped directly into the fieldbus telegrams, and another seven dedicated digital inputs accept machine-level signals such as limit switches or stop commands. A single voltage-scaled analog output provides 0 to +5 V for speed reference or actuator bias, making the module suitable for both discrete and proportional control loops.

Feedback resources are provided on a 15-pin D-Sub connector that supports EnDat 2.1, 1 Vpp sine-cosine, or 5 V TTL encoders. Sensor power is supplied internally at 5 VDC, and the channel can deliver up to 350 mA, which removes the need for an external regulator. The main board includes an analog input range of ±10 V for torque or velocity command signals, and the MA1 daughter card adds 2 differential inputs and 2 analog outputs for secondary axes. The MD1 expansion adds 12 more digital inputs and 8 sourcing outputs, so motion events, interlocks, and diagnostics can be handled without an external PLC.
