Chapter 4 Configure and Start Up the Drive
Rotate Tune
If the Motor is uncoupled, perform a Rotate Tune by using the procedure in
Autotune/Static Tune
on page 97. The screens show how to configure the test
for Rotate Tune. This test is used when the motor is not coupled to the load, or
the load is low friction. Rotate Tune is used to better identify motor flux and
stator electrical properties, which are used to automatically tune the torque/
current loop.
The Rotate Tune test causes motor rotation at different speeds while it is
executing. Set 00:70 [Autotune] to Rotate Tune (3). See step 7
on page 99 for
more information
Inertia Tune
After the Autotune and Rotate Tune are complete, perform an Inertia Tune.
The motor should be uncoupled. During the test, the drive/motor is
accelerated using the entered Autotune Torque value. The time required to
accelerate the motor and load from zero speed to rated speed is measured.
The Inertia Tune test causes motor rotation at different speeds while it is
executing. Set 00:70 [Autotune] to Inertia Tune (4). See step 7
on page 99 for
more information.
ATTENTION: If the drive was never operated before (new installation), verify
that safeguards are in place to remove power safely from the drive during an
unstable situation where the drive can produce undesired motion.
