The Motor Capacity attribute is the real-time estimate of the continuous rated
motor thermal capacity utilized during operation based on the motor thermal
model. A value of 100% would indicate that the motor is being used at 100% of
rated capacity as determined by the continuous current rating of the motor. If the
drive device applies I
2
T overload protection rather than thermal model based
overload protection, the Motor Capacity value is zero until the motor current
exceeds the product of the Motor Overload Limit and the Motor Rated
Continuous Current. Once in an overload condition the Motor Capacity
increases from 0 according to the I
2
T calculation. A value of 100% in this case
indicates that the drive has used up 100% of the motor's I
2
T overload capacity.
The motor overload protection method applied by the drive device is indicated by
the Motor Overload Protection Method attribute.

The Inverter Capacity attribute is the real-time estimate of the continuous rated
inverter thermal capacity utilized during operation based on the inverter thermal
model. A value of 100% would indicate that the inverter is being used at 100% of
rated capacity as determined by the continuous current rating of the inverter. If
the drive device applies I
2
T overload protection rather than thermal model based
overload protection, the Inverter Capacity value is zero until the inverter current
exceeds the product of the factory set Inverter Overload Limit and the continuous
current rating of the inverter. Once in an overload condition the Inverter Capacity
increases from 0 according to the I
2
T calculation. A value of 100% in this case
indicates that the drive has used up 100% of the inverter's I
2
T overload capacity.
The inverter overload protection method applied by the drive device is indicated
by the Inverter Overload Protection Method attribute.
