Product Description:

The VT 16000-2X-100 is a servo amplifier card produced by Bosch Rexroth Indramat for the VT 1600 Servo Amplifiers series. Installed in hydraulic press and motion platforms, the unit coordinates several closed-loop axes by processing position feedback from incremental and absolute encoders, issuing analog commands to proportional valves, and exchanging data with a supervising PLC. Its role in an automation cell is to translate numeric NC data into synchronized hydraulic movements that match the programmed tool path and cycle time.

The controller accepts up to eight analog combination-module inputs for pressure or position signals and provides four analog outputs to drive servo-proportional valves. Program loading and diagnostic interaction are carried out with the COM252M communication package over an RS-232 link. Two counter slots read two incremental encoders, while a cam generator can manage 32 cross-axis cam profiles so coupled tooling fires at precise angles. Eight digital inputs and eight digital outputs are present for limit switches, solenoids, or interlocks. The rack accommodates four plug-in boards, and the internal backplane routes power and fieldbus signals so wiring stays organized. Up to four hydraulic axes can be tuned separately, each receiving its own set of gain, ramp, and dead-band parameters.

An SSI board can monitor four absolute encoders, enabling the amplifier to track cylinder positions after power cycles and resume operation without rehoming. The NC kernel stores 2,000 complete data sets, letting job changes occur without a host download. Motion blocks are coded in the DIN 66 025 NC language and then queued for execution. For supervisory control, the card links to Siemens S5-115U, S5-135U, S5-155U, or a modern S7-400 PLC, letting existing installations upgrade axis resolution while retaining the plant's primary controller.
