Product Description:
The CSH01.1C-SE-ENS-EN1-EN2-L1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It mounts on compatible power sections to execute closed-loop positioning, velocity, and torque tasks in industrial automation. This arrangement separates the control electronics from the power stage while keeping both units integrated in the same drive assembly. It is intended for motion systems that require deterministic command updates and tightly timed feedback processing. The unit communicates with higher-level PLCs through a fiber-optic ring, delivering cycle-synchronous data exchange that is essential for coordinated multi-drive machinery.
The controller’s analog monitor channel has a resolution of 19.5 mV/inc, allowing fine-grained observation of internal variables during loop analysis. Idle operation draws only 7.5 W, which minimizes cabinet heat and eases UPS capacity requirements. Each of the four protected transistor outputs can source up to 500 mA for lamp loads, relays, or brake release coils, while command and diagnostic traffic moves across the SERCOS II interface at 2 or 4 Mb/s. When DC power is first applied, an inrush limiter caps the surge to 4 A for 100 ms to protect upstream fuses and prevent excessive bus droop. The module also offers four configurable digital outputs, eleven sink-type digital inputs, and a fast probe channel for position latch functions. These I/O resources support status signaling, interlocks, and simple actuator control without requiring a separate interface module.
Feedback and encoder support are distributed over three ports. EN1 provides Hall sensor feedback and supplies 250 mA at 5 V plus a resolver excitation of 18.2 Vpp at 4 kHz for hybrid motor encoders. EN2 supplies 5.0 V at 350 mA to power SSI or BiSS interfaces. The ENS high-speed input accepts incremental signals up to 500 kHz and furnishes 11.6 V to differential receivers. An internal probe circuit tags edge events with 1 µs accuracy during spindle orientation or registration cuts. This mix of feedback connections allows the control section to work with motors and external measuring devices that use different signal formats.
