Inverter Load Rating Settings

The duty rating mode of the inverter can be chosen from Normal Duty (ND), Low Duty (LD), and Very
Low Duty (VLD).
The rated current, excess duty endurance, and rated temperature of the inverter vary depending on the
duty rating mode.
A change of the inverter duty rating mode is reflected immediately after the Load type selection [Ub-03]
is changed.
Precautions for Correct Use
• When [Ub-03] is changed, the parameter set for the electric current is automatically adjusted
at the ratio of the changed rated current and the set value is changed accordingly.
• Another check is necessary if the electric current is set by using the excess duty limit func-
tion, direct current control function, electronic thermal function, excess duty warning function,
or low current detection function.
• When VLD is selected and the control mode is selected out of the Control mode selection,
1st-motor [AA121], the control mode is automatically set to the V/f control. Another check is
necessary when the control type setting is changed.
