F20.12 value is a percentage of the maximum reference source.
If the PID reference value is lower than the detected value (F20.12) in the detection time
（
F20.13
）
, the
inverter will implement PID reference loss alarm (E0025).
• When F20.12 or F20.13 is set to 0, the inverter will not detect PID reference loss fault.

F20.14 value is a percentage of the maximum feedback source.
If the PID feedback value is lower than the detected value (F20.14) in the detection time (F20.15), the
inverter will implement PID feedback loss alarm (E0026).
• When F20.14 or F20.15 is set to 0, the inverter will not detect PID feedback loss fault.

F20.16 value is a percentage of the maximum feedback source.
If the PID feedback value exceed the detection value (F20.16) in the detection time (F20.17), the
inverter will alarm PID feedback out of limiting (E0027).
• When F20.16 is set to 100 or F20.17 is set to 0, the inverter will not detect PID feedback out of
limiting fault.
