PID High Feedback
Detection Lvl
Sets the level that triggers Excessive PID Feedback [FbH] as a percentage of the
Maximum Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the
maximum output frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]

PID High Feedback
Detection Time
Sets the length of time that the PID feedback signal must be more than the level set in
b5-36 [PID Feedback High Detection Lvl] to cause Excessive PID Feedback [FbH].
