The REXROTH VT2000-52 is an analog servo amplifier from Bosch Rexroth’s widely used VT2000 series, originally developed under the Indramat brand for precise control of DC and brushless servo motors in industrial automation. Designed for applications requiring high dynamic response and smooth torque control—such as CNC machines, hydraulic servo valves, robotic arms, and plastic injection molding equipment—the VT2000-52 delivers up to 10 A peak current with true 4-quadrant operation (motoring and regenerative braking in both directions).
As an analog command interface drive, the REXROTH VT2000-52 accepts standard ±10 V velocity or torque signals from a motion controller or PLC, making it ideal for integrating into legacy systems where digital fieldbus communication (e.g., SERCOS, EtherCAT) is not available. It supports incremental encoder feedback for commutation and speed regulation, and can be adapted for tachometer or resolver feedback using optional interface modules (e.g., FE01, FE02). The unit features comprehensive protection functions—including overcurrent, overtemperature, and undervoltage shutdown—and includes status LEDs and test points for rapid commissioning and troubleshooting.
Housed in a compact, DIN rail-mountable enclosure, the REXROTH VT2000-52 remains a go-to solution for maintaining and upgrading decades-old production lines where reliability, simplicity, and motor compatibility outweigh the need for modern digital networking.

Main Features and Advantages
Analog Simplicity with Industrial Robustness
The REXROTH VT2000-52 avoids the complexity of parameterization software—setup is performed via onboard potentiometers for gain, offset, and current limits. This makes it exceptionally reliable in environments where EMI or IT restrictions limit PC-based configuration tools.
True 4-Quadrant Operation
Capable of driving and braking in both forward and reverse directions, the VT2000-52 enables energy-efficient deceleration and precise tension control—critical in winding, pressing, and test stand applications.
Legacy Motor Compatibility
Fully compatible with classic Indramat motors such as MSK, HMD, and MDD series, allowing plants to retain proven mechanical systems while replacing only failed electronics—saving significant capital expenditure.
Integrated Safety and Diagnostics
A dedicated 24 V enable input acts as a hardware safety interlock; if removed, the drive disables output immediately. Fault codes are indicated via LED blink patterns, and test points allow oscilloscope-based signal verification during tuning.
REXROTH VT2000-52
Application Field
The REXROTH VT2000-52 is commonly found in:
- Metal forming presses(position and force control)
- Plastic injection molding machines(screw recovery and clamp control)
- Printing and converting lines(tension regulation)
- Test benchesfor automotive or aerospace components
- Legacy CNC retrofitswhere analog axis cards (e.g., from Siemens or Heidenhain) still output ±10 V signals
Its ability to operate without a digital network makes it especially valuable in brownfield facilities undergoing partial modernization—where new PLCs may coexist with older motion subsystems. Many users also deploy the VT2000-52 in R&D labs and prototype machines due to its ease of integration and transparent control behavior.
