Setting procedure |
|
|
Adjust the following parameters: |
| |
: Select " | " to set the motor constant independently using the ∼parameters. | |
: Set the slip frequency for the motor. A higher slip frequency reduces motor slipping correspond- | ||
ingly. (The slip frequency can be set on the basis of test records of the motor.) |
| |
: Adjust the primary resistive component of the motor. Decreases in torque due to a possible volt- | ||
age drop during | ||
(Perform adjustments according to the actual operation.) |
| |
: Adjust the secondary component of the motor. This parameter is enabled only when | is | |
set to " | ". A larger adjustment value gives more slip correction. (Perform adjustments according | |
to the actual operation.) |
| |
: Set the excitation inductance for the motor. A larger inductance creates a smaller | ||
(Perform adjustments according to the actual operation.)
: Set a load inertia moment with a multiple of the motor inertia moment. A transient response can be adjusted. A larger adjustment value reduces inertial overshoot, and thus prevents the occur- rence of an overcurrent and an overvoltage, correspondingly.
: Set "1" if the rated capacity of the motor is one size smaller than that of the inverter.
6 | * Sensorless vector control may not operate properly if the motor capacity differs from the appli- | |
cable rated capacity of the inverter by more than two grades. | ||
