1.
Set the rated motor voltage in
(No function at the setting of "9999" or "8888".)
2.
Set
Pr.71 Applied motor
3.
Set frequency and voltage to be set in
CAUTION
• Make sure to set the parameters correctly according to the motor used. Incorrect setting may cause the motor to overheat
and burn.
NOTE
• The adjustable 3 points V/F is enabled under V/F control.
• When Pr.19 Base frequency voltage = "8888 or 9999", setting of Pr.71 = "2" is not available. To set "2" in Pr.71, set the rated
motor voltage in Pr.19.
• A write disable error "
• Set frequency or voltage for each point in Pr.100 to Pr.105 within the range of Pr.3 Base frequency or Pr.19 Base frequency
voltage.
• When Pr.71 = "2", the inverter calculates the characteristic of the electronic thermal O/L relay for a standard motor.
• By simultaneously using Pr.60 Energy saving control selection and the adjustable 3 points V/F, further energy saving effect
is expected.
