If a position controller is being used, a position error in that controller may have
accumulated during the jogging operation. This error results in a command signal
from the position controller to the amplifier. Clear this position error before starting
normal operation; otherwise, the amplifier will make a sudden move in the direction
to eliminate the position error.
Auto-tuning operation with PY Setup Software
1. Select Test Mode on Main Menu.
2. Select Offline Auto Tuning on Test Mode Menu.
3. You will be prompted whether or not an OFV (deviation) alarm should occur on
when tuning is completed. Select "yes" if you want an alarm generated (this could
serve as an indication to your controller that the axis is no longer in position).
Otherwise select "no".
4. Select High, Medium, or Low Tuning on Menu.
5. Select Yes for Offline Tuning Start Okay?
6. Tuning Successful window will appear showing tuning values.

In applications where auto-tuning is not suitable, the servo loops may be tuned manually.
If you are not familiar with the operation of PI (Proportional and Integral) controls,
please review our Handbook of AC Servo Systems which is available as a PDF file from
our website.
If you are in position mode, refer to the diagram on page 68 for a complete list of
parameters that affect tuning. If you are using Velocity Control refer to page 79 for a
