H33: Enter the motor nameplate rated current.

H34: Enter the measured current when the motor is running at rated frequency without load. Enter 50%
of the rated motor current when it is difficult to measure the motor no load current.

H36: Enter motor efficiency as shown on the nameplate.

H37: Select load inertia related to the motor inertia as shown below.
H37 [Load inertia
