The Bosch Rexroth VT-VACAF-500-10/V0 Force Control (0811405147) is an advanced analog amplifier designed to manage high-response valves with precision and efficiency. This device boasts a robust set of features, including a pressure differential controller with PID behavior, ensuring responsive and stable operation in various applications. It is equipped with short-circuit-proof outputs and additional electronics via a daughter card, enhancing its functionality and reliability. The amplifier is suitable for installation in standard 19" racks, adhering to the common European format for ease of integration into existing systems. It offers external shut-off capabilities for the pressure controller, adding an extra layer of safety and control. Users will appreciate the separate acceleration and braking ramps that can be adjusted independently or switched off entirely, providing flexibility in controlling the motion profiles. With an adjustable area adjustment specifically designed for cylinder applications, this device caters to precise force control requirements. Its compatibility with pressure sensors (ranging from 0...10 V to 4...20 mA as detailed in data sheet 30271) further extends its versatility. The unit also includes supply provisions for these pressure sensors as well as cable break detection features to ensure continuous monitoring and immediate response to any sensor issues. Overall, the Bosch VT-VACAF-500-10/V0 Force Control offers a comprehensive solution for controlling valve operations with precision, making it a valuable component in a wide range of industrial settings where accurate force application is critical.

a	Ideal development (only a square is shown)
b	Problem: P share too small Solution: ➝ Rotate Kp against 16 (fine adjustment) → P gain > see table 2, DIL 11–13
c	Problem: P share too large Solution: → Rotate Kp against 1 (fine adjustment) → Use DIL 11–13 to reduce the P gain according to table 2
d	Problem: P share correct, control deviation too large Solution: → Increase the I gain share according to table 3 → Rotate KI against 16
e	Problem: Time constant of the I share too low Solution: ➝ Rotate KI against 16 until control deviation and vibration are perfect → if KI = 16 is not sufficient, the P share must also be reduced, see table 2
f	Problem: D share too low Solution: ➝ Rotate KD against 16 → D share >, see table 1 (DIL 6–10)
