Figure 6.34 Motor overload protection curve.
The value can be determined by the following formula:
Motor overload protection current = (motor rated current / inverter rated current) * 100%
Notice:
l
This parameter is normally used when rated power of inverter is greater than
rated power of motor.
l
Motor overload protection time: 60s with 200% of rated current. For details,
please refer to above figure.
