F4 Speed Loop, Torque and Flux Control
Parameter
Function codes F4.00 ～ F4.07 are valid in no
PG vector control mode.
In vector control mode, change speed
response character by setting proportional
gain P and integral time I of speed regulator.
1. Speed regulator (ASR) has structure as
showed in 󽗉gure F4-1. KP is proportional gain
P, TI is integral time I.
Fig. F4-1 Speed Regulator
In vector control mode, these above function
codes are used to adjust steady-speed
precision of motor. When motor is overload
and the speed is low, increase the parameter,
otherwise decrease the parameter.
Positive slip compensation factor works for
the speed when motor slip ratio is positive,
and negative slip compensation factor works
for the speed when motor slip ration is
negative.
