Starting Up the Drive for Vector Regulation 2-27
Step 8. Perform Vector Regulator Self-Tuning
Before performing the self-tuning procedure, you should have performed steps 1
through 7 above and adjusted all the parameters as described. Note that U.016 may
also need to be set if your application requires field weakening.
This step describes how to start the vector regulator self-tuning procedure. This
procedure is enabled by setting parameter U.008, Torque Self-Tune Enable, to ON.
Self-tuning is performed by the drive and determines the proper no-load current value
for parameter U.006 and, for flux vector control (U.001
≠
SE), the encoder PPR value
for parameter U.001. These values must be accurate to ensure that rated motor
torque, speed, and horsepower can be developed for drives set up for vector
regulation. During the procedure, the drive will accelerate up to the value specified in
U.017 (Motor Top Speed).
Verify the following before starting the self-tuning procedure:
• The motor is unloaded.
• The drive is not running. If the RUN LED is on, press the STOP/RESET key.
• There are no faults in the error log. If a fault is flashing on the display, refer to
chapter 5 for instructions on clearing the errors.
How to Interrupt the Self-Tuning Procedure:
If the procedure is enabled only but not active (S-En is displayed), set U.008 to OFF.
If the procedure is active (S-Ac is displayed), press the STOP/RESET key.
Step 7.4 Press the ENTER key to save the displayed value.
After pressing ENTER, the same parameter
number is displayed. You can now go to the
next step.
!
ATTENTION: The motor will rotate during the self-tuning procedure. Stay
clear of rotating machinery. Failure to observe this precaution could result
in severe bodily injury or loss of life.
ATTENTION: The motor must be uncoupled from the driven load during
the self-tuning operation or incorrect parameter values will result. This
includes any shaft-coupled devices, such as reducers, belts, and brakes.
Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
