6-3
Note 1.
The value will be set in 0.01-mH increments if the resistance is less than 100 mH and 0.1-mH
increments if the resistance is 100 mH or over.
Note 2.
The default setting for this parameter is the standard leakage inductance of the maximum
applicable motor.
6-1-2 Adjusting Output Torque in Vector Control
•
The Inverter controls the output torque of the motor according to the required load torque in vector
control. Normally, no special adjustments are required. Adjust the output torque if the maximum
torque of the motor is unavailable or improvements are required in the output torque and response in a
low-speed range.
H
Adjusting the Torque Compensation Limit (n109)
•
Adjust the set value in n109 (torque compensation limit) if the maximum torque of the motor is insuffi-
cient or to limit the output torque to a certain degree while the motor is driven by the Inverter in vector
control.
•
Set the torque compensation limit in percentage based on the rated output current of the Inverter as
100%.
Compensating Torque Insufficiency
•
Set n109 to a larger value if the maximum torque of the motor is insufficient.
•
Set the value in 5% increments while checking the operation of the Inverter and motor.
•
Check that no overload (OL1 or OL2) is detected. If an overload is detected, decrease the set values or
consider the use of an Inverter model or motor with a higher capacity.
Limiting Output Torque
•
Set n109 to a smaller value if the fluctuation of the output torque is large and heavy shock is imposed
on the load, or excessive output torque is not required.
•
Set the value according to the condition of the load.

Note 1.
The Inverter in torque compensation control limits the torque at a current 1.5 times larger than
the set value.
Note 2.
This parameter is enabled only when the Inverter is in vector control.
H
Adjusting the Torque and Response through the V/f Pattern (n011
through n017)
•
The Inverter in vector control uses the V/f pattern as the reference value of the output voltage. There-
fore, by adjusting the V/f pattern the output torque and response are adjusted.
•
If the application requires high torque, adjust the V/f pattern so that the output voltage at the required
frequency will be high. Furthermore, energy-saving effects can be expected by decreasing the output
voltage values in the frequency ranges where high torque is not required.
