In order to apply effective overload protection to
different kinds of motors, the motor overload
protection factor should be correctly set to limit the
Max.output current of the driver. The factor is the
percentage of motor rated current to the rated output
current of the driver.
When the motor’s power level matches the driver, the
protection factor can be set to 100%, as showed in Fig.
FA-1.
Fig.FA-1 Motor Overload Protection Factor
When the power of VFD is larger than the motor, in
order to apply effective overload protection to motors
with different specification, the factor should be set
correctly as showed in Fig.FA-2.
Fig. FA-2 Motor Overload Protection Factor Setting
The factor is calculated by the formula below:
Generally, the max. load current is the motors rated
current.
