Closed Loop Adaptive Tune
The adaptive tune automatically calculates,
under certain operating conditions, the
percentage no load current and the rated rpm
(slip frequency). The HPV 900 Series 2
software uses these two adaptive tune
calculated values to obtain the maximum
performance from the motor.
Adaptive Tune Operating Conditions
The HPV 900 Series 2 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 (see Figure 38). This selection will
also load nominal values for the other motor
parameters listed in Table 24
Now, enter the motor nameplate data into
the needed motor nameplate parameters
(see Figure 38)
Tuning Motor No-Load Current
With a balanced car, run the car at 70%
contract speed from top floor to the bottom
floor then back to the top floor.
During these runs verify under DISPLAY
MENU - POWER DATA D2 that the
MOTOR TORQUE is between
15%. If the
value is larger then
15% the car is not
balanced correctly.
