Product Description:
The CSH01.2C-NN-ENS-MEM-CCD-NN-S-NN-FW is a modular motion and communication controller designed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive rack, it links axis drives, encoders, and plant networks so coordinated interpolation, safety monitoring, and parameter storage can occur on a single card. By handling setpoint generation and real-time feedback inside the drive cabinet, it supports decentralized automation where fast servo loops and a compact control footprint are required. Its combined control and communication functions also reduce the need for separate hardware in densely packed multi-axis systems.
The analog front end captures reference signals with a bandwidth of 1.4 kHz, allowing the control loop to respond to rapid command changes. A high input impedance of 160 kOhm helps keep upstream signal levels stable, while process values are returned on a unipolar output of 5 V. Each digital step equals 19.5 mV/Inc, which provides fine resolution for velocity or torque feedback. Encoder processing uses a cutoff frequency of 500 kHz for reliable decoding of high-resolution sine-cosine or TTL sensors. The module also accepts TTL inputs up to 400 kHz, applies a probe pulse width of 4 microseconds for precise latching, and provides internal enable power from an 11.6 VDC, 500 mA rail.
Cross communication runs as Master on the IEEE 802.3 physical layer, while the engineering connector offers a 100Base-TX link for setup and service access. Each digital output can deliver up to 500 mA, and the integrated relay is rated for 24 VDC at 1 A, allowing direct actuation of brakes or contactors. Differential encoder lines use 120 ohm termination, which helps preserve signal quality on high-speed feedback channels. The analog outputs are also filtered to improve noise immunity where the controller operates alongside multiple switching drive axes.
