Product Description:
The CSH01.1C-S3-EN2-EN1-MA1-S1-S-NN-FW is a plug-in control section created by Bosch Rexroth Indramat for use in Rexroth drive assemblies. Part of the CSH Advanced Controllers series, it manages axis commands, encoder evaluation, and safety responses inside multi-axis automation platforms. By combining fieldbus connectivity, analog I/O, and feedback processing on one board, it functions as the real-time interface between a machine-level PLC and the associated power modules.
In continuous operation, the controller dissipates only 7.5 W, reducing internal cabinet heating. A startup surge reaches 4 A but is limited to a pulse duration of 100 ms, so upstream protection can tolerate the brief inrush. Command exchange with the supervisory PLC is carried over SERCOS III, providing deterministic cyclic telegrams for motion profiles and diagnostics. Encoder supply on the EN2 port is stabilized at 5.0 V DC, which supports EnDat 2.1, 1 Vpp sine-cosine, or 5 V TTL feedback formats. The second encoder interface accepts HSF or resolver feedback, which allows digital and analog sensors to be used on the same axis.
The EN1 connector carries a hall/serial supply of 8 V DC plus a resolver excitation rated at 18.2 Vpp AC. EN2 can source up to 350 mA, which supports multiturn encoders or absolute position transducers. Two differential input channels and two voltage output channels are provided on the MA1 block; each path spans ±10 V, enabling direct control of proportional valves, tension sensors, or external drives without signal conditioning. Safety integration uses a 24 V / 3 mA logic input that activates stop functions and a 24 V / 0.5 A transistor output that can disengage power contactors once the axis reaches a safe state. This arrangement also allows the control section to exchange safety status with external switching hardware.
