H
: Used to set the rated current (A) of the motor. Enter the rated current printed on the
motor’s rating plate.
H
: Used to set the no-load current in percentage with respect to the rated current of the
motor. Enter the value calculated from a motor test report value or the power factor
printed on the rating plate of the motor.
H
: Used to set the rated rotational speed (min
-1
) of the motor. Enter the rotating speed
printed on the motor’s rating plate.
H
: Used to adjust the response to the frequency command.
• Increase the value to increase response.
• Decrease the value to decrease response.
Adjust the value in increments of 10 (%) or so while checking the effective response.
H
: Used to adjust the effective response to the frequency command.
• Increase the value if overshooting or hunting occurs.
• Increase the value if the speed reducer makes a gear noise.
• Increase the value if overvoltage tripping occurs on completion of deceleration.
Adjust the value in increments of 10 (%) or so while checking the effective response.
