FAQ

Q: When should I choose 5464-552 over 5464-551?
A: Choose 5464-552 when your application requires integrating control to eliminate steady-state error, such as precise valve positioning where long-term drift is unacceptable. Use 5464-551 for simpler proportional control applications.

Q: Does 5464-552 require external position feedback?
A: Yes. The integrating function requires LVDT, RVDT, or equivalent position feedback to close the control loop. Without feedback, the integrating function cannot operate correctly.

Installation Guide

1. Install 5464-552 into NetCon 5000 chassis slot.
2. Connect servo valve coils and position feedback (LVDT) to designated terminals.
3. Configure integrating gain, proportional gain, and deadband in control software.
4. Perform step response test to tune integrating time constant.
5. Verify no oscillation or hunting at steady-state position.

Selection Tips

• Feedback Sensor: Ensure LVDT/RVDT signal range matches the module's input specifications.
• Tuning: Integrating drivers require careful tuning—allocate time for commissioning and stability verification.
