PID Feedback Loss Detection
When performing PID control, be sure to use the PID feedback loss detection function. Otherwise if the PID
feedback gets lost, the Inverter output frequency may accelerate to the maximum output frequency.
Low Feedback (b5-12 = 1 or 2)
When b5-12 is set to 1 and the PID feedback value falls below the PID feedback loss detection level (b5-13)
for a time longer than the PID feedback loss detection time (b5-14), a “FBL - Feedback Loss” alarm will be
displayed at the operator and inverter operation is continued.
When the same happens and b5-12 is set to 2 a “FBL - Feedback Loss” fault will be displayed on the digital
operator and the inverter operation will be stopped. The motor coasts to stop and the fault contact is operated.
The time chart for PID feedback loss detection is shown below.
Fig 6.81 Low PID Feedback Loss Detection Time Chart
High Feedback (b5-12 = 3 or 4)
When b5-12 is set to 3 and the PID feedback value exceeds the PID feedback loss detection level (b5-13) for a
time longer than the PID feedback loss detection time (b5-14), a “FBL - Feedback Loss” alarm will be dis-
played at the operator and inverter operation is continued.
When the same happens and b5-12 is set to 4 a “FBL - Feedback Loss” fault will be displayed on the digital
operator and the inverter operation will be stopped. The motor coasts to stop and the fault contact is operated.
The time chart for PID feedback loss detection is shown below.
