Product Description:

The CSH01.1C-PL-EN1-EN1-NNN-NN-S-NN-FW is an axis controller card from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. It serves as the control section in multi-axis drive assemblies, translating motion commands from the machine PLC into real-time drive signals for industrial automation tasks such as packaging lines and material handling cells. By combining sensor feedback with program instructions, the board determines velocity, position, and torque targets for connected power sections.

The card’s electronics require a base consumption of 7.5 W, a figure that helps calculate cabinet power budgets and thermal dissipation. Its analog monitor channel sources up to 5 V / 1 mA, allowing low-power reference outputs for external indicators or test points. Control inputs are rated at 24 V / 3 mA, so standard PLC sourcing modules can drive the 16 digital lines without added buffering. Complementary outputs switch loads of 24 V / 0.5 A, which is adequate for pilot relays or status lamps. For machine data exchange, a parallel interface supplies 16 inputs / 16 outputs channels, supporting deterministic handshake signals between the controller and higher-level logic, while the RS232 serial port handles parameter setting or diagnostics. The PL module mounted on the board draws 1 W, so its heat contribution is minimal compared with the main logic section.

Each En1 encoder channel is powered from an internal supply limited to 6 W, with the excitation rail held at DC 8 V to suit TTL or HTL feedback devices. When serial communication is preferred, the RS232 connector operates up to 115 kBaud, providing sufficient bandwidth for setup software. Relay contacts on the board can switch auxiliary circuits carrying DC 24 V, 1 A, eliminating the need for external interposing relays. Resolver feedback is supported through a 4 kHz carrier and 18.2 Vpp excitation, enabling absolute shaft position calculation over a full mechanical revolution.
