Product Description:

The CSH01.1C-S3-EN2-NNN-MD1-S1-S-NN-FW controller is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is intended for cabinet installation where it supervises multi-axis drive groups, processes encoder feedback, and exchanges real-time data with higher-level PLCs. By combining motion logic with integrated safety inputs and outputs, the unit helps coordinate packaging, pick-and-place, and material-handling operations with deterministic timing.

During continuous operation, the electronics draw 16.5 W, so cabinet thermal planning can be based on low internal dissipation. When the supply is first energized, an inrush current of 4 A appears briefly before the device settles to its rated load. Command and feedback data move over the fiber-optic real-time bus SERCOS III, while a separate copper port supports standard Ethernet messaging at 100Base-TX speeds. For analog interfacing, the board provides a 5 V voltage channel and a current channel that can source or sink up to 1 mA, allowing direct connection to potentiometers, reference generators, or actuator transducers. Pulse-train tasks are accommodated by an adjustable output whose maximum width is 100 ms.

The EN2 measurement section filters incoming sine signals up to 500 kHz and accepts square-wave tracks up to 1000 kHz, giving the motion processor ample bandwidth for high-resolution feedback. Encoder Interface 1 supports EnDat 2.1, 1 Vpp, or 5 V TTL formats and delivers a regulated 5 V supply to the sensor. The MD1 extension carries 12 digital inputs and 8 digital outputs for proximity switches, relays, or lamp stacks, each following the stated timing limit. Safety Technology I/O channels draw 3 mA when monitoring external guards and can drive contactors with up to 0.5 A, so emergency stops can be wired without auxiliary relays.
