Product Description:

The CSH01.2C-PL-ENS-EN1-CCD-NN-S-NN-FW is a modular motion-logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. In multi-axis drive assemblies, the unit manages position loops and coordinates field devices through integrated communication channels. By combining decentralized I/O handling with drive-side setpoint generation, it serves as the core interface between higher-level PLCs and IndraDrive servo inverters in automated assembly lines, packaging stations, and material-handling cells. Its role is to keep command flow, feedback handling, and local signal processing in one control platform so connected axes can operate in a coordinated manner.

For networked operation, the controller implements the Ethernet-based cross-communication standard IEEE 802.3 and dedicates 1 W of internal power to that link. Each of the 16 parallel digital inputs is opto-isolated, while 16 transistor outputs have a maximum sink current of 500 mA per channel. Logic circuits for the drive bus are energized by a stabilized 8 V rail that can deliver 250 mA for servo feedback electronics. Separate field wiring is supplied by an I/O bus that tolerates a peak draw of 1.1 A. When switching inductive valves or contactors, the output stage can absorb 400 mJ of release energy, which helps protect the transistors from voltage spikes. Two auxiliary 1 W supplies also feed the onboard parallel module for panels or status lamps.

Output groups that fire simultaneously can source a total of 1000 mA, which helps when several controlled functions are active at the same time. Rotor position channels rely on a resolver interface that excites the stator windings at 4 kHz and is rated for 6 W. The pre-amplifier supplies an amplitude of 18.2 Vpp to the transducer. When a standard incremental or absolute encoder is used instead, the board provides a dedicated 6 W output at 12 V to energize the sensor head. Combined with the digital servo current limit of 250 mA, this arrangement supports low-voltage coupling of feedback devices without requiring external regulators.
