Dynamic or Static Autotune tests will be performed during the Autotune Procedures.
• Dynamic - the motor shaft will rotate during this test. The dynamic autotune
procedure determines the stator resistance, motor flux current, and leakage
inductance. The test to identify the motor flux current requires the load to be
uncoupled from the motor to find an accurate value. If this is not possible then the
static test can be performed.
• Static - the motor shaft will not rotate during this test. The static test determines
only IR Voltage Drop (62) and Ixo Voltage Drop (64). This test does not require the
load to be uncoupled from the motor.
The static and dynamic tests can be performed during the Start-up routine on the LCD
OIM. The tests can also be run manually by setting the value of Autotune (61) to “1,”
(Static Tune) or “2” (Rotate Tune), respectively, and then starting the drive.
After the Static or Dynamic Autotune the Inertia test should be performed. The motor
shaft will rotate during the inertia test. During the inertia test the motor should be
coupled to the load to find an accurate value. The inertia test can be performed during
the Start-up routine on the LCD OIM. The inertia test can also be run manually by
setting Inertia Autotune to 1 = “Inertia Tune”, and then starting the drive.
Troubleshooting the Autotune Procedure
If any errors are encountered during the Autotune process drive parameters are not
changed, the appropriate fault code will be displayed in the fault queue, and Autotune
(61) is reset to 0. If the Autotune procedure is aborted by the user, the drive
parameters are not changed and the Autotune (61) parameter is reset to 0.
The following conditions will generate a fault during an Autotune procedure:
• Incorrect stator resistance measurement
• Incorrect motor flux current measurement
• Load too large
• Autotune aborted by user
• Incorrect leakage inductance measurement
