0.00–100%
The FBV (Feedback Value Check) message P5.1 (2.3) = 25 is
output if the actual value in RUN mode is below the lower limit
value P9.16. It stays active until:
The actual value exceeds the upper limit value P = 9.15
The frequency inverter switches from RUN mode to STOP mode

If the PID controller is activated (P9.1 = 1), and the deviation
between the setpoint and the actual value exceeds the value
entered here, the PID monitoring is activated. Setting at P5.1
