What does the FLG gain adjustment do for the Altivar 58 drive?

The gain function allows adjustment of the response time of the drive controller to sudden changes in the motor load.  Decreasing the gain parameter slows the responce time of the drive controller.  Increasing the gain parameter makes the drive controller respond more quickly to load change.  This parameter should be increased in applications where the undesirable changes in motor speed occur due to changes in motor load.  Applications that have fast cycle times or high torque requirements may require and increase in gain.
