Motor power factor (Cos )
(MOTOR PWR FACT)
Value:
0.50 - 0.99
0.75
Function:
This parameter calibrates and optimizes the AEO
function for motors of different power factor (Cos ).
Description of choice:
Motors having > 4 poles have a lower power factor
which would restrict or prevent use of the AEO function
for energy savings. This parameter allows the user to
calibrate the AEO function to the power factor of the
motor so that AEO can be used with motors of 6, 8,
and 12 poles as well as 4 and 2 poles.
NB!
The default value is 0.75 and should
NOT be changed unless the specific mo-
tor has power factor lower than 0.75. This
is typically the case for motors having
more than 4 poles or low efficiency mo-
tors.
