0: Method 1
1: Method 2
Sets the internal speed feedback detection control gain in the automatic frequency
regulator (AFR).
If hunting occurs, increase the set value. If response is low, decrease the set value.
Sets the time constant used for speed feedback detection control (AFR).
Sets the AFR time constant to be used during regen.
0: Disabled
1: Enabled
Sets the time required to accelerate the motor at 100% torque from 0 to the nominal
speed.
Sets the ratio between motor and load inertia. Lower this setting if overshoot occurs at
the end of acceleration.
0: Disabled
1: Enabled
2: Test Mode
Sets the proportional gain for the Speed Feedback Compensation.
0: Disabled
1: Line-to-line resistance tuning
2: Voltage correction.
Decrease this setting for motors with a relatively large rotor time constant.
If overload occurs, increase this setting slowly in increments of 0.1.
