Product Description:

The CSH01.1C-CO-EN2-NNN-MEM-L1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside modular IndraDrive servo inverters, the board coordinates axis motion, handles fieldbus traffic, and supervises local safety inputs. In an automation cell, it translates high-level commands into encoder-synchronized torque or velocity references, allowing precise positioning, stable speed regulation, and direct diagnostic feedback within the drive system.

The card accepts an acknowledge supply of 24 V / 1 A that keeps internal logic active during emergency-stop chains. One analog output channel delivers 5 V for reference tracking or test-point use during signal checks. Network communication is handled through CANopen/DeviceNet, giving deterministic data exchange with multiple drives on the same trunk and supporting coordinated control across linked axes. For virtual feedback, the encoder emulation port drives line receivers up to 40 m away at 1 MHz, which helps maintain reliable signal transfer where a remote receiving device must follow the generated position data. Direct sensor inputs are supported through the EnDat 2.1 / 1 Vpp / 5 V TTL connection, allowing the board to work with absolute and incremental feedback devices in one control platform.

The sensor interface tolerates up to 35 ohms of line impedance and supplies current for stable operation of connected measuring devices over extended cable runs. The fieldbus lines terminate on an X60 5-pin spring terminal, which simplifies wiring and permits sense cables up to 75 m for position feedback monitoring. A single-line display reports operating mode and error codes directly on the drive front, so local status remains easy to read during operation. The board can also transmit absolute position frames in SSI format alongside incremental replicas for downstream equipment. In addition, a dedicated lockout input accepts a 24 V control signal at low current to force torque off during protective interlocks, while the maintenance port supports RS-232 diagnostics on suitably short cables.
