What it means
F07751 (Drive: valve does not respond) is raised when a valve is parameterized with a valve feedback signal (p0218.2 = 1) but the valve does not follow the setpoint. The manual describes this fault for SINAMICS S120 and S150.
Why it appears
- A valve with a valve feedback signal is parameterized (p0218.2 = 1), however the valve does not follow the setpoint.
What to check
- If the valve does not actually have a feedback signal, correct the configuration and set p0218.2 = 0 for a valve without valve feedback signal.
- Check the valve natural frequency in p0216.
- If the sign is incorrect, invert the valve actual value by means of p0218.3.
- Check the valve and the valve connection.
Parameters the manual names
- p0218 (Cylinder safety configuration / Cyl safety config): this is where the valve feedback is configured — p0218.2 = 1 means valve with valve feedback signal, p0218.2 = 0 means valve without valve feedback signal; p0218.3 inverts the valve actual value when the sign is incorrect.
- p0216 (Valve natural frequency / Valve fn): the valve natural frequency that must be checked for this fault.

Questions technicians ask
What does fault F07751 mean in SINAMICS?
The drive has parameterized a valve with a valve feedback signal (p0218.2 = 1), but the valve does not follow the setpoint given to it. The fault is described for SINAMICS S120 and S150.
How can I fix fault F07751?
If the valve has no feedback signal, set p0218.2 = 0. Otherwise check the valve natural frequency in p0216, invert the valve actual value with p0218.3 if the sign is wrong, and check the valve and its valve connection.
Which parameters belong to fault F07751?
p0218 (Cylinder safety configuration) with the settings p0218.2 and p0218.3, and p0216 (Valve natural frequency).
