PID Mode Setting Sets the type of PID control.
0 : Disabled
1 : Standard
2 : Standard (D on feedback)
3 : Fref + PID Trim
4 : Fref + PID Trim (D on feedback)
5 : Same as 7series & prior, b5-01=1
6 : Same as 7series & prior, b5-01=2
7 : Same as 7series & prior, b5-01=3
8 : Same as 7series & prior, b5-01=4
Note:
Use settings 5 to 8 instead of settings 1 to 4 when the drive is a replacement for Varispeed F7.

RUN
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]

RUN
PID Output Limit Sets the maximum possible output from the PID controller as a percentage of the Maximum Output
Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.

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]
