[ATune Frictn]
The system friction as measured by the auto tune
cycle is represented through this parameter.

[ATune Inertia]
System inertia as measured by auto tuning. This
parameter is calculated during auto tune and is
the time that the motor and load takes to reach
[ATune Vel] at [ATune Current] and back to zero
rpm. This needs no manual user adjustment,
since it is a product of the auto tune function. To
determine the inertia of the machine system, use
the following formula:

[ATune Select]
This parameter initiates an auto tune cycle that
measures the [ATune Inertia] and [ATune Frictn]
by accelerating the motor up to the [ATune Vel]
at the [ATune Current]. The parameter also
calculates the gains based on auto tune
information.

"Idle"
Indicates the auto tune system can be used, written
command forces the system to idle.
1
"Axis Tune"
Written as a command, initiates the auto tune
process, messages will be displayed to enable axis,
wait, disable axis. "Calculate" is also performed.
2
"Calculate"
Calculates gain coefficients based off data acquired
during auto tuning. This command can be issued
manually to calculate gains after manual
modifications to the auto-tune acquired information.
[ATune Vel]
This parameter specifies the maximum velocity
of the motor attained during an auto tune cycle,
as well as direction of movement.
