5-8 Control and Configuration Software V6.1
Use the following procedure to tune the Speed Loop.
Step 1. Enter the inertia value for the motor and load in the Lb-Ft**2 box. Continue to
step 2.
or
a. Click Start Self-Tune. The following message is displayed:
“The load must be coupled to the motor shaft before running this test. If the
load is not coupled, the test results will be incorrect. Select OK when you
are ready to begin this test or Cancel to quit.”
b. Lock out and tag all power to the drive and its load.
c. Connect the load to the motor.
d. Remove the lockout and reapply power to the drive.
e. Click OK. The following message is displayed:
“Warning:
This test will set Current Limit (P.005) to the Magnetizing Current (U.006)
plus 20%. The motor will be run at 10% of synchronous speed for several
seconds and then step to 95% of synchronous speed. Select OK to begin
the test or select Cancel to quit.”
f. Click OK to start the motor and accelerate to 95% of base speed.
g. The drive will run the motor and driven machinery to measure inertia.
h. When the measurement is complete, click OK to continue.
