Product Description:

The CSH01.3C-PL-ENS-NNN-CCD-L2-S-NN-FW control section is a plug-in module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Intended for IndraDrive platforms, the unit provides motion and logic processing so that servomotors, actuators, and peripheral devices can be coordinated from a single slot in the power drive. In an automation cabinet, it acts as the central point that interprets field signals, executes parameter sets, and exchanges data with the plant network to synchronize speed, position, and process variables.

Analog channels dominate its local feedback layer. The differential input stage can read voltage references in a range of ±10 V, and its input path presents 160 kΩ of resistance, limiting sensor loading. Outgoing commands are generated across a 0 to 5 V span, and they resolve changes in steps of 19.5 mV/inc while driving loads down to 5 kΩ. During idle operation, the module draws only 8.5 W, allowing dense cabinet layouts. Fast parameter access is provided through the 100Base-TX engineering port, which remains isolated from the real-time drive bus to prevent cross-traffic.

Plant-wide communication is handled over the integrated cross-communication bus that complies with IEEE 802.3. When power is first applied, the input capacitor network briefly absorbs a peak of 4 A, after which current settles to its base level. Legacy diagnostics are supported through the asynchronous port, which reaches a maximum rate of 115 kBaud, and fast edge counting is performed on TTL inputs up to 400 kHz. Sixteen discrete inputs and sixteen outputs allow direct wiring of limit switches or relays. Encoder channels supply 11.6 VDC at 500 mA, accept 1.0 Vpp sinusoidal signals through a 120 Ω termination, and feed position data into the controller without external converters.
