VT 16000-2X-101 by Bosch Rexroth Indramat

The VT 16000-2X-101 is a servo amplifier card manufactured by Bosch Rexroth Indramat for the VT 1600 Servo Amplifiers series. It mounts in a control rack and translates numeric motion commands into current-controlled signals for proportional valves. The module acts as the interface between a machine controller and hydraulic power stages, closing position and pressure loops directly in industrial automation cells.

Signal processing is supported by 8 combined analog inputs that accept command and feedback voltages or currents and 4 combined analog outputs that return conditioned values or drive external devices. For discrete control, the card offers 8 digital inputs for limit switches or mode selection and 8 digital outputs for status flags or interlocks. The motion power stages can control up to 4 hydraulic axes, allowing synchronized operation of multiple cylinders or motors from a single board. The measuring system interface accepts analog, incremental, and SSI transducers, so mixed feedback types can be processed without auxiliary hardware. Four plug-in modules provide slots for pressure controllers, fieldbus cards, or diagnostic functions.

Position reference handling is extended by 2 counter and encoder channels for quadrature or single-ended pulse trains and by 4 SSI encoder channels for absolute position devices, providing deterministic sampling for axis summing junctions. Complex camming tables are supported through 32 cross-axis cams, allowing each hydraulic axis to trigger timed events on companion axes without PLC intervention. A maximum of 2,000 NC sets can be stored in nonvolatile memory, enabling intricate multistep cycles that remain available after power loss. The multi-format measuring inputs allow the amplifier to manage coordinated servo-hydraulic motion while reducing system wiring and controller processing demands.
