CSH01.1C-PB-ENS-EN2-MA1-S2-S-NN-FW

The Bosch Rexroth Indramat CSH01.1C-PB-ENS-EN2-MA1-S2-S-NN-FW from the CSH Advanced Controllers series features native PROFIBUS master communication and two precise analog outputs to support advanced drive applications. This control section employs a primary encoder option Indradyn/Hiperface/1 Vpp/TTL and an optional EnDat2.1 encoder for high-resolution feedback. Designed for efficient thermal performance, the unit relies on natural convection cooling without fans and maintains a consistent SERCOS cycle period of 1000 µs. The control section consumes just 7.5 W of power and accommodates an inrush current of 4 A for reliable start-up dynamics.

The module provides extensive I/O capabilities with 11 digital inputs, two of which double as touch probes, and 4 digital outputs for versatile signal routing. A single analog input and an integrated RS232 serial port enable straightforward integration into industrial networks, while a dedicated relay output offers fail-safe switching. Safety is enhanced by the S2 (safe motion) option, and all functions remain fully operational up to 1000 m altitude under standard atmospheric conditions. Pulse-width modulation can be tuned across a 2–16 kHz frequency range with a maximum pulse width of 100 ms, ensuring precise current shaping and motor control.

Commissioning is streamlined with current control periods of 62.5–125 µs, speed control times of 125–250 µs, and position control times of 250–500 µs, delivering responsive axis regulation. The compact control section measures 103 mm wide x 241 mm tall x 49.5 mm deep and must be installed in compliance with applicable safety regulations by trained personnel. In total, the CSH01.1C-PB-ENS-EN2-MA1-S2-S-NN-FW offers a robust foundation for high-performance motion systems in packaging, machining, and process automation.
