Product Description:

The CSH01.1C-PL-ENS-ENS-NNN-NN-S-NN-FW is a single-axis motion control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside a modular drive rack, this card manages command processing, sensor interfacing, and I/O coordination for IndraDrive servo inverters. Its control logic processes encoder feedback and issues velocity, torque, and position setpoints so the drive can follow PLC instructions and machine-level sequences. It communicates with the higher-level automation PC through a dedicated parallel interface, which avoids the delay associated with fieldbus traffic during time-critical cycles. This arrangement is well suited to packaging, printing, and assembly machines that require direct axis supervision inside the drive system.

Two differential analog channels accept process signals with an input resistance of 160 kΩ, which helps prevent excessive loading of upstream transmitters. The analog outputs can source up to 1 mA with a ceiling of 5 V, allowing the card to provide reference signals for external converters or test points without overstressing connected circuits. Digital output lines are also available; the high level is fixed at 24 VDC and each driver can deliver 0.5 A, so contactor coils and similar loads can be switched directly from the board. This combination lets the card exchange low-level analog references and discrete control signals with peripheral devices through the same control platform.

The base board draws 7.5 W from the shared backplane, which helps limit heat buildup in densely populated cabinets. During power-on, an inrush of 4 A is tolerated for 100 ms before the current settles to its normal operating level. Relay-isolated outputs rated for 1 A provide an alternative interface when electrical isolation is required, and a matching set of 16 inputs supports parallel handshaking with legacy controllers. Separate isolated switching paths are useful when external devices must remain electrically separated from the control electronics. The ENS encoder ports also supply operating power to two feedback devices, helping maintain stable position acquisition during startup and continuous motion.
