VT 16000-2X-111 by Bosch Rexroth Indramat

The VT 16000-2X-111 is a servo amplifier card manufactured by Bosch Rexroth Indramat for the VT 1600 Servo Amplifiers series. It translates numerical commands into controlled current for proportional valves, enabling position, pressure, and velocity control loops on hydraulic machinery. Installed in a rack with I/O and encoder boards, the unit serves as the motion core for presses, injection systems, and other CNC stations that require synchronized multi-axis control.

One combination module provides 8 analog inputs and four analog outputs; the inputs accept signals from position or pressure transducers, while the outputs send reference levels to proportional valves or external drives. Setup and diagnostics are performed through the COM252M communication program. Dynamic response can be tuned because the software includes the PDT1 regulator option alongside PI and PIDT1 control modes. For coordinated events, the controller stores 32 cross-axis cams that trigger outputs when multiple axes reach preset positions. A counter board with 2 counter encoders captures high-speed feedback from incremental scales. Eight digital inputs and eight digital outputs are also available for connecting limit switches and solenoids.

The system has four card slots, and a fully equipped rack can manage 4 hydraulic axes, with each axis configurable for analog, incremental, or SSI feedback. The controller retains up to 2000 NC sets, allowing extensive part programs to run locally. Motion commands follow DIN 66025, so standard G-code can be downloaded without conversion. The amplifier exchanges process data with SIMATIC controllers and supports the S7-400 PLC for high-level sequencing. Four SSI encoder inputs accommodate compatible position-feedback devices in multi-axis applications. An analog pressure transducer channel also supports closed-loop force or pressure control without requiring an additional signal-processing module.
