Product Description:

The CSH01.3C-PL-ENS-ENS-CCD-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into Rexroth drive racks to manage motion axes, read incremental or absolute position devices, and pass deterministic signals to higher-level automation. Within an industrial cell, the unit coordinates drive functions, bridging field controllers with motor-side feedback so that speed, torque, and positional loops remain synchronized during indexing, positioning, and continuous-motion tasks. That arrangement lets the drive system react quickly to command changes and incoming feedback events.

This control section exchanges cyclic data through a Parallel Interface, and it offers 16 parallel inputs for fast machine signals such as limit switches or probe triggers. Cross-controller messaging adheres to the IEEE 802.3 standard, and the module is configured as a network master to publish timing frames to subordinate stations. Two separate feedback channels are available, and the hardware provides 2 encoder interfaces that follow a standard encoder evaluation format and support a 500 kHz encoder cutoff frequency so high-resolution transducers can be read without aliasing. Sixteen parallel outputs share a common 24 V rail and can source up to 500 mA total for solenoids or relay coils. Safe-torque-off functions are handled by external hardware, while the onboard analog outputs can be used for proportional valves or reference speed generation.

Each feedback channel uses 12-bit conversion, which balances signal detail with low latency during closed-loop operation. Encoders may draw up to 500 mA encoder supply current from the card, and the regulated supply is 11.6 V encoder supply voltage to support connected feedback devices. For discrete counting tasks, the TTL ports accept pulses up to 400 kHz TTL input frequency, allowing direct interfacing with incremental gratings in high-speed pick-and-place systems. This supports fast counters and encoder-style inputs without requiring a separate interface module. The line receivers limit loading to 120 Ω to preserve edge fidelity on incoming signals.
