Integral Limit
Sets the upper limit for integral control (I) 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 Offset Adjustment
Sets the offset for the PID control output 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]

Sets the level that triggers PID Feedback Loss [FbL] detection as a percentage of the
Maximum Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the
maximum output frequency.
