Adaptive Tune
The adaptive tune automatically calculates,
under certain operating conditions, the
percentage no load current and the rated rpm
(slip frequency). The HPV 600 software uses
these two adaptive tune calculated values to
obtain the maximum performance from the
motor.
Adaptive Tune Operating Conditions
The HPV 600 software estimates the motor’s
percent no load current and the motor’s rated
rpm. These estimated values are only estimated
around a window of
±
25% of the parameter
settings for:
•
percent no-load current (% NO LOAD
CURR)
•
rated motor speed (RATED MTR SPEED)
The adaptive tune will estimate:
•
the motor’s percent no load current when
the motor torque is below 20%.
•
the motor’s rated rpm when the motor torque
is above 30%.
Using the Adaptive Tune to Obtain Maximum
Motor Performance
The following is a step-by-step procedure to
optimize the window around which the adaptive
tune will estimate its two values.
NOTE: Although the listed speeds are
recommended, the adaptive tune procedure can
be ran initially at lower speeds, as long as the
speed is greater than 10% of contract speed.
Initial Set-up
Select a valid Motor ID or one of the two default
motors (either 4 or 6 pole) for the MOTOR ID
parameter
The default motor selections for the motor id will
place a zero values in the motor nameplate
parameters. This selection will also load nominal
values for the other motor parameters listed
below.
