Automatic offset adjustment
Automatic offset adjustment is that after the servo drive measures the offset, it automatically adjusts
the analog voltage of velocity command. The offset needs to be saved to the servo drive. (Save RAM
to Flash) If not, automatic offset adjustment must be done after the servo drive is turned on again.
The conditions for performing automatic offset adjustment are: (a) The servo drive is in servo OFF
state. (b) The controller does not input any signal.
Click on Tools in the main screen of Thunder and select Analog offset. Click on Set zero button in
Analog offset window to automatically adjust offset.
