The PID control function provides closed-loop system control. In case PID feedback is lost, the
inverter output frequency may be increase to the maximum output frequency.
10-11=1:Warning
A feedback loss condition is detected when the PID feedback value falls below the value set in
parameter 10-12 (PID feedback loss detection level) for the time set in parameter 10-13 (PID
feedback loss detection time). PID feedback loss warning message "
Fb
" will be displayed on the
keypad and the inverter will continue to operate.
10-11=2:Fault
A feedback loss condition is detected when the PID feedback value falls below the value set in
parameter 10-12 (PID feedback loss detection level) for the time set in parameter 10-13 (PID
feedback loss detection time). PID feedback loss fault message "Pb" will be displayed on the keypad,
the inverter stops and the fault contact is activated. Refer to figure 4.3.82
