13-2 Understanding the Auto-tuning Procedure
To manually run the auto-tune test, you need to use Autotune/Dgn Sel
(parameter 173). It has the following bit definitions:
Bits 6 through 15 are reserved; leave 0.
Important: You must run the motor phase rotation test, inductance
test, resistance test, flux test, and inertia test in order.
To run a particular test:
1. Set the bit in Autotune/Dgn Sel that corresponds to the test you
want to run.
2. Enable the drive.
When the test is complete, the bit is cleared (0). If a fault occurred,
refer to the Troubleshooting section.
You can run the auto-tune tests individually.
Running the Power Structure
and Transistor Diagnostics
Tests
The power structure and transistor diagnostics routines let you
determine if any problems exist in the power structure of the drive and
determine the probable cause of these problems.
The diagnostic software determines hardware problems through a
series of system tests. These tests are parameter dependent. The test
results depend on drive size, motor size, system wiring, and other
factors that affect system voltage and load impedance.
In most cases, the software can properly determine if faults exist;
however, there may be some installations where some faults cannot be
properly checked. In general, test results are listed as failed if a
questionable case is found. You must review test results with respect
to the whole drive system to properly interpret whether a real problem
exists.
You can run the transistor diagnostics before a start by setting bit 8 of
Logic Options (parameter 17). Transistor diagnostics require motor
current, so a user-start transition is required to run the tests.
To run the transistor diagnostics independently:
1. In Autotune/Dgn Sel (parameter 173), set bit 0 to 1.
2. Enable the drive.

1 Although the motor does not have to be coupled to the load during these tests, you
can have it coupled to the load during any of the tests. The motor must be coupled
to the drive for all of these tests.
