• The main circuit power supply must be ON.
• There must be no overtravel.
• The servo must be OFF.
• The control method must not be set to torque control.
• The gain selection switch must be set to manual gain selection (Pn139 = n.
• The first gains must be selected.
• The test without a motor function must be disabled (Pn00C = n.
• There must be no alarms or warnings.
• The parameters must not be write prohibited.
• The tuning-less function must be disabled (Pn170 = n.

Operating Procedure

Use the following procedure to perform autotuning without a host reference.
 If you specify not estimating the moment of inertia, set the moment of inertia ratio (Pn103)
correctly. If the setting greatly differs from the actual moment of inertia ratio, normal control
of the machine may not be possible, and vibration may result.
 If you are using the SERVOPACK for phase control, set the mode selection to 1. If 2 or 3 is
selected for the mode, correct phase control may not be possible.
1.
Confirm that the moment of inertia ratio (Pn103) is set correctly.
2.
Click the
maWin+.
3.
Select Tuning in the Menu Dialog Box.
The Tuning Dialog Box will be displayed.
Click the Cancel Button to cancel tuning.
for mode 2 or 3, the SERVOPACK will change to position control automatically to perform
autotuning without a host reference. The SERVOPACK will return to speed control after
autotuning has been completed.
