Notes:
1) Standard duty VT motor rating based on a 110% overload for 1 minute. Heavy-duty VT or Standard Duty CT
motor ratings based on 150% overload for 1 minute. The motor horsepower ratings are based on VFD nominal
voltage and 4-pole motor design. Operation at lower input voltages or motors with six or more motor poles
may require to upsize the drive depending on actual motor FLA rating.
2) Output voltage cannot exceed the input voltage. An output voltage should be programmed in the range from
input voltage to a minimum of the VFD voltage rating.
3) The standard conduit box attachment adds 1.8kg (4 lbs.), as minimum, to the weight of the drive.
4) MMC (Multi Motor Control) function is not available for 150HP and above VFDs.
5) De-rate VFD by 50% when the single-phase power will be applied to the VFD.
6) UL Open Type VFD with installed UL Type 1 kit.
