Product Description:
The CSH01.3C-S3-NNN-MA1-CCD-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It is a multi-protocol motion and logic controller that installs in IndraDrive power sections to coordinate servo axes, sensors, and fieldbus devices. Within an automation cell, this module executes drive-based control tasks and helps synchronize position, velocity, and process signals between machines and supervisory PLCs. Its compact format allows direct cabinet mounting alongside power electronics. This arrangement helps keep control functions close to the drive hardware and reduces the need for separate interface modules in the cabinet.
Two differential analog inputs on the MA1 expansion board present an input resistance of 160 kΩ, minimizing load on upstream transducers. Each channel is digitized at a step size of 1.23 mV/inc, which supports fine setpoint or feedback scaling without external amplifiers. The card also offers two analog outputs and four combined I/Os that can be configured as additional sensing or actuation points. Deterministic network integration is handled by SERCOS III, and the section assumes the master role for cross-communication between drives. For discrete loads, the digital output channel sources up to 0.5 A. Engineering access is provided through an RJ-45, 8-pin connector running 100Base-TX Ethernet, which supports direct service communication with the controller.
The two probe inputs capture edge events with a minimum pulse width of 4 µs, enabling accurate position latching for fast axes. Analog command values generated by the MA1 outputs are resolved at 12 bit, matching the precision used by many servo drive interfaces. Switching functions rely on a relay channel approved for up to DC 24 V, 1 A, and the contact is normally open. Long-distance or legacy diagnostics can be performed over the built-in RS232 serial interface, supplementing the Ethernet service port. This combination of probe capture, analog signaling, relay switching, and serial access supports integration with both newer automation networks and older auxiliary equipment.
