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.
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.
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 RUNNING 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.
