Product Description:

The VT 16000-2X-131-A servo amplifier belongs to the VT 1600 Servo Amplifiers series from Bosch Rexroth Indramat. It is a rack-mount motion and pressure control module that links electro-hydraulic axes with numeric control programs in automated machinery. By combining closed-loop position, velocity, and pressure regulation on several hydraulic cylinders, the unit acts as an interface between the machine PLC and proportional valves, letting production equipment execute coordinated moves defined in a standardized NC language.

Using the integrated communication software COM252M, parameter sets can be transferred from a supervisory PC while the amplifier is online. Motion computation is supported by 2 counter module channels that capture reference marks or probe points from external sensors. For axis interlocking, the firmware stores 32 cross-axis cams, providing time-critical switching without additional hardware. Up to 4 hydraulic axes can be commanded concurrently, and each axis may draw on as many as 2000 NC sets to execute contour segments or pressure profiles. Four peripheral module slots are available for expansion cards, and the board accepts position data from analog, incremental, or SSI feedback devices as well as a dedicated analog transducer for pressure monitoring.

At the periphery, the basic rack presents 8 analog inputs, 4 analog outputs, and 8 digital inputs alongside 8 digital outputs, enabling direct wiring of valve coils, sensors, and limit switches. Four SSI encoder inputs let high-resolution displacement signals reach the control loop. Part programming follows DIN 66025, so tool path code generated on standard CAM systems can be executed without conversion. The amplifier exchanges process data over PROFIBUS or through parallel I/O with Siemens controllers, and its PLC interface list includes S5-115U; S5-135U; S5-155U; S7-400, assuring straightforward integration into existing plant architectures.
