Inertia Tune
The Inertia Autotune selection involves only one test. Several parameters are
updated from the test results. Refer to the tables in the Individual Tests section.
A temporary command initiates an inertia test of the motor/load combination.
The motor ramps up and down while the drive measures the amount of inertia.
This option applies only to FV modes selected in P35 [Motor Ctrl Mode].
Obtain final test results with the load coupled to the motor as long as the rotation
won’t damage the machine.
Test Dependencies
When running the flux test, the selected accel rate is used unless it is less than 10
seconds. In this case, 10 seconds is forced. In the case of the Inertia test, a 0.1
second accel rate is used. The selected direction used during normal operation is
used for all rotation tests. Also, during any rotate test, the normal speed limits are
enforced.
The thermal manager is always being run in the 2 ms loop, which provides
protection during all of the Autotune tests.
