Using an Altivar 11 drive on an undersized motor, how can it be set up to use V/Hz control? The reason this is needed is so that the acceleration and deceleration is linear.

The FLG parameter should be set at 0% which essentially makes ATV11 a volts per hertz drive.

In some cases, when motors are very small, the drive can not sense the current. When declerating using factory settings, the drive may appear to hesitate to decelerate then suddenly decelerate at the end of the ramp time. Lowering the FLG to 0 can often effectively deal with this issue.
