Advanced Auto Torque Boost Setting Details
Code Description
DRV-16 Fwd Boost Adjusts the torque boost amount for forward rotation
DRV-17 Rev Boost Adjusts the torque boost amount for reverse rotation.
DRV-26 Adv ATB Filter Filter gain for calculating the Auto Torque Boost value.
DRV-27 Adv ATB M Gain Gain for calculating the reverse Auto Torque Boost value.
DRV-28 Adv ATB G Gain Gain for calculating the regeneration Auto Torque Boost value.
If there is no load, the additional voltage amount due to Auto Torque Boost is 0, which gives
the same result as the normal manual boost.
When the load is applied, the amount of compensation voltage varies depending on the
operation and reverse directions.
If you set the DRV-16 and DRV-17 values differently when using Advanced Auto Torque Boost
at no load, a current hunting operation may occur.
