☞ Note 1: Ls and Noload-Curr are only valid during Motor
Rotation mode.
☞ Note 2: The motor constants values change with
temperature change, so auto tuning is to be conducted
after the temperature of the motor is stabilized.
☞ Note 3: The auto-tuning result could be different unless
LG motor is used.
☞ Note 4: The actual motor parameters (Rs, Rr, Lsigma,
Tr) can be used or set by user.

FU2-45: P Gain for Sensorless Control
FU2-46: I Gain for Sensorless Control
SL P-gain is the proportional gain of speed controller. If
this value is set high, you can get fast speed response
characteristic. However, if this value is set too high, the
steady state characteristics may become unstable.
SL I-gain is the integral gain of speed controller. If this
value is set low, you can get better transient response
characteristic and steady state characteristic. However,
if this value is set too low, there may be an overshoot in
speed control.
