Product Description:

The CSH01.2C-NN-EN2-EN2-CCD-S1-S-NN-FW is a drive and motion controller module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit installs into IndraDrive power sections and supplies axis control, fieldbus handling, and safety monitoring for coordinated multi-axis machinery. By combining encoder evaluation, analog I/O, and real-time bus functions on one plug-in card, it forms the computational core that closes position, velocity, and torque loops in industrial automation.

This controller operates from a logic supply of DC 24 V and draws a base power of 8.5 W when the application program is idle. The single-ended analog input channel presents a high input impedance of 160 kΩ, minimizing loading on external sensors. Fast position capture is supported by a probe circuit with an edge accuracy of 1 µs, allowing precise synchronization with external triggers. Cross-communication between multiple IndraDrive units is handled through SERCOS III; this deterministic fiber or Ethernet ring transfers setpoints and status data every cycle and removes the need for an additional fieldbus card. The board carries two identical encoder interfaces for EnDat 2.1, 1 Vpp, or 5 V TTL feedback, so two feedback devices can be evaluated without extra hardware.

The analog output channel sources a reference level of 5 V at up to 1 mA for external actuators or test points. During power-up, the logic rails exhibit a typical inrush current of 4 A that lasts no longer than 100 ms, so the power supply must accommodate this short surge without triggering protection circuits. An Ethernet-based engineering port gives access to device parameters and diagnostics, while an RS232 serial interface remains available for legacy service tools. Safety Technology I/O terminals are integrated so safe shutdown or enable signals can be wired directly to the card.
