Characteristics of the particular motor used, and should there fore be made
by the user when the drive is installed. Jobsite adjustment of “IR” is
necessary to achieve specified regulation. The adjustments are permanent;
periodic readjustment is not necessary. (The IR adjustment is set fully
counter clockwise when using tachometer feedback.)
Perform adjustments per Table II and in the order listed in Table II. The
adjustments are completely independent of each other except as noted
below:
a)
“IR” has a slight effect on
“MIN”, but “MIN” does not
effect “IR”
b)
“MIN” has a slight effect on
“MAX”
Performing adjustments in the order listed in Table II thus eliminates any
necessity for repeating a calibration operation.
Note that torque limit (“TORQ”) is independent of the other adjustments.
Since this is basically a protective adjustment, preset at the factory, it should
not be readjusted except to decrease the limit point.
