APPENDIX
– Adaptive Tune
154
NOTE: If you are having problems getting
the motor torque under 15% the cause
may be:
No compensation chains
If the elevator system has no
compensation chains, achieving
balanced condition may be difficult. In
that case, the MOTOR TORQUE
should be between
15% for as much
of the run as possible.
High elevator system friction
If the elevator system has high friction,
achieving motor torque of under 15%
may be difficult. In that case, have
less than the balance car weight in the
car, thus letting the counterweight help
to overcome the frictional losses. In
this case, you should look only at the
estimated values in the up direction
and run the car in the up direction a
number of times before changing any
parameter settings.
Also, verify that the FLUX REFERENCE is
100%. If the value is not equal to 100%
reduce the speed to less than 70% contract
speed and check again.
While still performing these top / bottom
runs observe under DISPLAY MENU -
POWER DATA D2 the EST NO LOAD
CURR value.
Enter this estimated value into the motor
parameter.
Continue iterating the above two steps until
the two values are within 2%. If the values
do not converge after two iterations, verify
the information entered in the initial set-up
is correct.
After the values converge, again verify the
MOTOR TORQUE < 15% and the FLUX
REFERENCE = 100%.
Tuning Motor’s Flux Saturation Curve
With a balanced car, run the car at 100%
contract speed from top floor to the bottom
floor then back to the top floor.
During these top / bottom runs observe
under DISPLAY MENU - POWER DATA
D2 the EST NO LOAD CURR value.
Compare the displayed value EST NO
LOAD CURR with the value entered for %
NO LOAD CURR under the ADJUST
MENU - MOTOR A5
If the EST NO LOAD CURR is 2% larger
than the % NO LOAD CURR then,
decrease the FLUX SAT SLOPE 2 by 10%.
