A521 [Freq 1 Kp] Related Parameter(s): A509, A510
A523 [Freq 2 Kp]
A525 [Freq 3 Kp]
PowerFlex 525 only.
Sets P-gain of “Vector” control mode when in frequency region 1, 2 or 3 for faster speed response during dynamic-state where motor is still accelerating. If A509 [Speed Reg Sel] is set
to 1 “Manual”, these parameters can be changed.
Values Default: 100.0%
Min/Max: 0.0/500.0%
Display: 0.1%

A522 [Freq 1 Ki] Related Parameter(s): A509, A510
A524 [Freq 2 Ki]
A526 [Freq 3 Ki]
PowerFlex 525 only.
Sets I-gain of “Vector” control mode when in frequency region 1, 2 or 3 for faster speed response during steady-state where motor is at its rated speed. If A509 [Speed Reg Sel] is set to
1 “Manual”, these parameters can be changed.
Values Default: 0.100 s
