4001
PI
PROPORTIONAL
GAIN
PI Controller Proportional Gain. Higher values provide
a greater change in the drive output frequency in
response to small changes in the feedback signal.
Too high a value can cause instability 1.0
0.0…30.0
4002
PI INTEGRAL
TIME CONSTANT
PI Controller Integral Time. Larger values provide a
more damped response for systems where the overall
process responds slowly 1.0 s
0.0…30.0 S
4005
PI OPERATING
MODE 0
0 : DIRECT
OPERATION Use this mode if an increase in the motor speed
should result in an increase in the feedback signal
1 : INVERSE
OPERATION Use this mode if an increase in the motor speed
should result in a decrease in the feedback signal
