F7085 fault in siemens sinamics V90 drive indicates Open-loop/closed-loop control parameters changed. This means the drive automatically adjusted your control parameters because they exceeded hardware limits or were incompatible with the current hardware features.
Cause:
Open-loop/closed-loop control parameters have had to be changed for the following reasons:
- As a result of other parameters, they have exceeded the dynamic limits.
- They cannot be used due to the fact that the hardware detected not having certain features.
Remedy:
It is not necessary to change the parameters as they have already been correctly limited.
