►
H33: Enter the motor nameplate rated current.
►
H34: Enter the measured current when the motor is running at rated frequency after the
load is removed. Enter 50% of the rated motor current when it is difficult to measure the
motor no load current.
►
H36: Enter motor efficiency on the nameplate.
►
H37: Select load inertia based on motor inertia as shown below.
H37 [Load inertia rate]
0 Less than 10 times motor inertia
1 About 10 times motor inertia
2 Greater than 10 times motor inertia
►
As the loads are heavier, the speed gap between rated RPM and synchronous speed is
widening (see the figure below). This function compensates for this inherent slip.
