increase in resistance signifies an increase in motor temperature. The ADDvantage-32
PLUS takes the difference between the two values and calculates the temperature
(A***:MOTOR TEMP).
X***:THERMAL TC - Used to set up the IIR integrator for the motor (A***:11R
INTEGR), it is the amount of time the ADDvantage-32
PLUS can operate at 150% rating before a value of 100 is
obtained. A value of 60 seconds at 150% will allow the
motor 8 seconds at 200%. A value of 425 seconds at 150%
will allow the motor 60 seconds at 200%. (See the
following chart.)
X***:M-TEMP WARN - This parameter is used to generate the warning bit D***:M-
TEMP WARN. When the calculated motor temperature
goes above this value, D***:M-TEMP WARN turns on.
This bit could then be configured to a user fault or a digital
output to display a warning. This temperature is calculated
from the change in field resistance.
The drive IIR is not settable and is set to fault when the drive is R/A outputting 150% of
the rated bridge for 60 seconds. On non-UL AFM applications, this can be disabled by
the factory.
There are three possible IIT curves to choose from: one that trips after 8 seconds of
200%, one that trips after 10 seconds of 250%, and one that trips after 10 seconds of
300%. See Figure 3-2B.
Use parameter Y***: IIT CURVE to select the desired curve.
