Product Description:

The CSH01.1C-S3-ENS-NNN-MD1-NN-S-NN-FW is a modular motion-logic controller manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed as the control section of an IndraDrive stack, it commands servo axes, processes local I/O, and exchanges data with supervisory PLCs to coordinate gantry systems, pick-and-place arms, and high-speed packaging lines. As a universal drive controller card, it combines axis processing, fieldbus communication, and encoder handling to provide deterministic control in decentralized machine architectures. This arrangement lets the control section manage motion tasks locally while still supporting coordinated machine-level control.

The controller shares cyclic setpoints and status frames over SERCOS III; this real-time ring keeps connected drives synchronized for torque and velocity control. Two differential analog channels accept signals within ±10 V, and each presents an input impedance of 160 kOhm, so transducers can be connected without external buffers. Eight transistor outputs are rated at 24 V, 0.5 A, allowing the card to actuate solenoid valves or pilot relays directly. For position feedback, the front panel provides a 15-pin D-Sub female connector linked to the internal ASIC. The board performs encoder evaluation for incremental and absolute formats, supplies 500 mA to powered sensors, and terminates differential lines at 120 Ω to maintain signal integrity.

Additional interfaces broaden the controller’s application range. A fieldbus port built on an 8-pin RJ-45 jack conforms to IEEE 802.3u 100Base-TX, enabling PLC traffic over standard Ethernet. When extra machine signals are needed, the Digital I/O Extension adds twelve 24 V inputs, eight 24 V outputs, and a relay contact rated at DC 24 V, 1 A for isolated switching. Encoders that require power can draw 11.6 V at up to 500 mA from the dedicated rail. For direct local communication, an integrated RS-232 port offers a point-to-point channel independent of the real-time networks. Separating these auxiliary connections from the motion network helps the controller handle feedback devices and machine signals without burdening the primary control link.
