3. Set the Speed to the expected operation speed.
4. Set the Torque to the level you want to apply to the motor during the
Autotune.
The default of 100% Rated Torque usually give good results.
5. Set the Direction that is based on machine constrains.
Unidirectional tune profile measures inertia and friction. Bidirectional
tune profile adds measurement of active torque loading.
6. Click Start.
This message appears if you have edits that have not been applied. If you
don’t save pending edits, Autotune does not run.
The Autotune status should display Success. A tune configuration fault
can occur if any number of attributes are zero.
The Autotune profile accelerates and decelerates the motor according to
the Tune Direction.
TIP
Blue arrows next to a field means that these values are immediately
applied. Once you put a value in the field and then leave that field, it is
automatically sent to the controller.
Fault Description
Tune Configuration Fault A tune configuration fault can occur if any number of
attributes are zero. This occurs only when you use Nameplate
Data as the motor data source. The following attributes are
checked for zero:
• Tuning Torque
• Conversion Constant
• Drive Model Time Constant
• System Damping (Damping Factor)
• Rotary Motor Inertia
• Linear Motor Mass
– The Kinetix 350 drive does not support this attribute.
• Motor Rated Continuous Current
• PM Motor Rotary Voltage Constant
• PM Motor Linear Voltage Constant
• Rotary Motor Rated Speed
• Linear Motor Rated Speed
