Product Description:
The CSH01.1C-S3-ENS-EN2-MA1-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is a plug-in control section for IndraDrive power modules that executes motion commands, manages feedback, and coordinates auxiliary functions across multiple servo drives. By combining fieldbus communication with onboard analog and digital I/O, the card serves as a compact logic layer for axis control in high-speed automated machinery.
The controller’s base analog input range is ±10 V, allowing the drive to accept proportional speed or torque references from external sources, while the complementary base analog output supplies a reference of 5 V at 1 mA for status feedback to an external monitor. Digital inputs operate at a logic level of 24 V and sink only 3 mA, which helps reduce sensor loading, while the digital outputs can source up to 0.5 A for small relays or indicator lamps. Master communication takes place over the deterministic SERCOS III interface, enabling synchronous data exchange between the drive, PLC, and other motion nodes. The MA1 extension adds two ±10 V, 12-bit analog inputs and two matching analog outputs to provide additional process channels.
For high-precision edge-detection tasks, the probe input reacts within 1 µs, supporting electronic cam or registration functions. Point-to-point service diagnostics are available through the dedicated RS-232 serial port. The housing measures 241 mm in height, 49.5 mm in depth, and 103 mm in width, allowing dense mounting inside control cabinets. A relay contact rated at 24 VDC, 1 A provides isolated signaling to external interlocks. Two encoder ports expand feedback flexibility: X4 accepts IndraDyn, HIPERFACE, 1 Vpp, or TTL signals, while X8 supports EnDat 2.1 along with 1 Vpp and TTL formats. This arrangement supports compact integration while allowing multiple feedback types without extra daughterboards.
