Motor Constant 3 (Leak Inductance)
Program Motor Vector Motor Model
This parameter is used to set the leakage inductance of the
motor.
A larger setting here results in higher output torque at high
speeds.
Motor Constant 4 (Rated Slip)
Program Motor Vector Motor Model
This parameter is used to set the secondary resistance of the
motor.
An increase in this parameter setting results in an increase of
compensation for motor slip.
Exciting Strengthening Coefficient
Program Special  Special Parameters
This parameter is used to increase the magnetic flux of the motor
at low-speed. This feature is useful when increased torque at low
speeds is required.
Stall Prevention Factor 1
Program Protection  Stall
This parameter is to be adjusted in the event that the motor stalls
when operated above the base frequency.
If a momentary heavy load occurs the motor may stall before the
load current reaches the stall prevention level setting of F601.
A drop in the supply voltage may cause fluctuations of the load
current or may cause motor vibration. A gradual adjustment of
this parameter may alleviate this condition.
Start with a setting of 85 at these parameters and gradually
adjust them from there one at a time until the desired results are
produced.
Adjustments to this parameter may increase the load current of
the motor and subsequently warrant an adjustment at the Motor
Overload Protection Level setting.
