Product Description:

The CSH01.1C-C0-EN2-NNN-MEM-NN-S-NN-FW is an automation controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It serves as the primary command card inside IndraDrive systems, processing motion commands, fieldbus data, and local I/O signals so that servo axes follow programmed trajectories without an external PC. This role lets the controller coordinate axis response, manage communication traffic, and keep motion behavior consistent during synchronized machine cycles. The board mounts in the power section of the drive and supplies deterministic timing, interpolation, and safety-related logic needed for coordinated multi-axis movement.

The controller operates from a logic supply of 24 V DC, and its digital circuitry draws a steady 7.5 W while the system is running. When the rail is first energized, an inrush current of 4 A charges internal capacitors, so the upstream supply must tolerate that brief surge. Analog command channels are referenced to an output level of 5 V, giving connected motion hardware a common span for speed or torque setpoints. A matching En2 encoder port is intended to drive incremental sensors through a 35 Ω load without signal degradation. Pulse-train tasks such as position latching are limited to a maximum width of 100 ms, which helps preserve deterministic cycle times for axis control.

High-speed camming or electronic gearing is handled by the MEM interface, which streams position pulses at up to 1 MHz while adding only 2 W to the board’s thermal budget. This supports tightly timed synchronization tasks where pulse accuracy affects registration and axis coordination. The same channel can sink an En2 index current of 350 mA when driving long encoder cables, supporting stable feedback transmission over extended routing. Parameter downloads and diagnostics pass through an RS-232 link that supports cables up to 15 m and data rates as high as 115 kBaud. An onboard relay switches DC loads up to 1 A, isolating the control electronics from actuator lines.
