7B.4 Hpv 900 Adaptive Tune - O. Thompson Microflite Ultra 2000 Installation & Adjustment Manual

Microflite Ultra 2000 - Magnetek HPV 900 AC Vector Drive
Run the car from the top floor to the bottom floor. Observe the meter. The voltage
3.
should be -7.00 volts. If not, adjust MPU pot R28 to obtain an equal voltage, but of
opposite polarity, while the car is running up and down.
Note: It may be easier to adjust the R28 pot while the car is in leveling speed.
TEMPORARILY set the "ADVANCE COUNTS" parameter in the motion parameter screen
to 90. Run the car and adjust R28 to obtain the same speed reference but opposite
polarity while the car is leveling up and down.
4. If pot R28 was changed, it will be necessary to adjust pot R25 again. Verify that the
voltage to the drive is +7.00 volts in the up direction, and -7.00 volts in the down.
5. Observe the diagnostic screen on the monitor. Check that the actual car speed as
shown on the monitor is contract speed of the car. If not, adjust the CONTRACT MTR
SPD parameter to obtain as close contract speed as possible.
The car should now be running at contract speed. Some minor modifications may be
necessary to obtain the best ride from the car. If an adaptive tune is required, it must be
.
performed at this time

7b.4 HPV 900 Adaptive Tune

If the motor to which the drive is connected is an old motor and no data is available for it, an
adaptive tune must be performed. The adaptive tune requires that the car is run at contract
speed and is capable of lifting full load.
1. Select the "Default Motor" option for the Motor ID parameter. This will load default
values into the motor data parameters to prepare the drive for the adaptive tune.
2. Enter the following motor data into the drive:
a. Motor HP or kW from nameplate into "RATED MTR POWER."
b. Motor AC voltage from nameplate into "RATED MTR VOLTS."
c. Motor AC frequency (usually 60 cycles) into "RATED EXIT FREQ."
d. Motor nameplate full load amps into "RATED MTR CURR."
e. The number of motor poles into "MOTOR POLES."
f. Motor RPM with full load at the correct frequency into "RATED MTR SPEED."
NOTE: The Motor RPM value must be less than 900 for 8 pole motors, 1200 for 6 pole
motors, and 1800 for 4 pole motors or a drive fault will occur. The motor nameplate may
not be correct.
Place a balanced load into the car. Reduce the car speed to 70% of contract speed. To
3.
do this, adjust pot R25 on the MPU so 4.9 volts is present at relay board terminals
RJ20-7 (positive) to RJ20-7 (negative).
4. Run the car from top to bottom and back. While the car is running, monitor the MOTOR
TORQUE (found under Display Menu – Power Data D2). The torque should be
between + 15%. If not, verify that the car is balanced correctly.
Note: If the car does not have compensation, the motor torque will vary depending on
where in the hoistway the car is. Verify that the motor torque is between ± 15% as
the car passes through the center of the hoistway.
