Product Description:

The CSH01.1C-S3-ENS-EN1-EN2-S1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on an IndraDrive power base, it governs servo axes, evaluates multiple encoder formats, and distributes real-time data to plant controllers. By combining motion processing with onboard safety inputs, the unit helps simplify drive cabinet layouts in automated assembly, material handling, and processing equipment. This arrangement also reduces wiring complexity when several coordinated axes share the same control architecture.

For fieldbus connectivity, the card relies on SERCOS III, allowing synchronized communication between the drive, PLC, and HMI. The internal current loop updates every 125 µs, and the power stage can modulate up to 8 kHz so torque changes remain tightly controlled. During startup, the electronics admit a base inrush of 4 A for no longer than 100 ms, and continuous consumption drops to 7.5 W. The unit supports several feedback interfaces: Interface 1 performs standard encoder evaluation, Interface 2 handles resolver and HSF signals, and Interface 3 reads EnDat 2.1, 1 Vpp, or 5 V TTL feedback. The primary resolver channel uses a 4 kHz carrier to maintain accurate position acquisition during vibration.

The controller also provides 2 analog outputs for speed reference or diagnostics, while the configurable digital channel can deliver up to 500 mA to external devices. Encoder power is available on the ENS port at 11.6 V, and the EN2 connection supplies sensors with 5.0 V. Machine safe-stop circuits connect directly to the board through Safety Technology I/O, and a single normally open relay contact is available for hardwired fault signaling. This mix of analog, digital, and safety connections allows the control section to exchange command and status signals without separate interface modules for common machine functions.
