VT 16000-2X-110 by Bosch Rexroth Indramat

The VT 16000-2X-110 is a servo amplifier card produced by Bosch Rexroth Indramat, and it belongs to the VT 1600 Servo Amplifiers series. In a multi-axis hydraulic press or motion system, it conditions feedback signals and drives valves so the PLC can maintain target positions and forces. By integrating cam profiling with position, pressure, and synchronization loops, the card provides closed-loop control for up to four hydraulic axes within larger SIMATIC-based automation cells.

Each combination module attached to the amplifier supplies 8 analog inputs and 4 analog outputs, enabling proportional reference updates and sensor feedback on every axis. A separate digital board provides 8 digital inputs and 8 digital outputs for limit switches, interlocks, and diagnostic flags. For motion feedback, the controller accepts 2 incremental and 4 SSI encoder inputs, while the backplane supports analog, incremental, and SSI interfaces so mixed transducers can operate in one rack. The hardware stores 32 cross-axis cams that coordinate cylinder triggering with master motion. The controller can process commands for 4 hydraulic axes simultaneously. Up to four plug-in peripheral modules can expand fieldbus or memory capacity when complex tooling requires additional resources.

Application logic runs on the IP252mH platform, allowing the controller to manage a maximum of 2000 NC sets for detailed stroke tables and sequence steps. A PLC selects these data sets through the SIMATIC S5-115U, S5-135U, S5-155U, or S7-400 interface, allowing compatible Siemens controllers to direct hydraulic motion through the established control program. Fine-tuning is handled by the PDT1 position controller. Complementary control functions include a PIDT1 pressure and force regulator and a PI synchronization controller that aligns slave axes with a master axis. When higher-level coordination is required, available peripheral-module slots can accept communication cards for supervising additional sensors or field devices without exceeding the four-module limit.
