Product Line:

Resolution:
The nominal motor current parameter (nCr)  in  Drive menu 3, is from 0.25 to 1.36 of the nominal current rating for the drive (In).
In = drive controller constant torque output current rating shown on the drive controller nameplate.
The actual adjustment range is shown on the display for the nCr parameter is in terms of amps. The actual amperage range depends on the rating of the drive being used.
