Is the ILT setting for the ATV28 in terms of amps or in terms of percentage?

This adjustment is in amps.
The manual indicates the possible range of this setting as being 0.20 to to 1.15 In for 208/230 and 400/460 V drives and 0.50 to 1.15 In for 575 V drives. In is the current rating of the drive.
The above formulas are for calculating the adjustment range that is available for each size Altivar 28. The actual values in this parameter correspond to amps rather than a percentage or mulitplier value.
