Note: Always refer to the specific data sheet for the exact model (e.g., A4VSO 180 HD) for precise technical data.

3. Available Controls (Examples)

The pump's functionality is defined by its control. Common options include:

· HD Control: Pressure control. Adjusts displacement to maintain a preset system pressure (pressure compensation).
· EO Control: Electro-proportional displacement control. Flow is adjusted via an electrical input signal (e.g., 0-10V, 4-20mA), enabling easy integration with PLCs.
· LR Control: Power-limiting control. Limits the drive power consumption by reducing flow when a preset pressure is reached.
· EL Control: Electric control. Uses a solenoid valve to switch between two pressure settings.
